Grandtrek WT M3 Snow Tires – Are These the Right Choice for Safe Winter Traction?

[ad_1]

Dunlop’s new Grandtrek WT M3 snow tires are a class-leading winter traction tire for luxury SUVs and 4x4s. This tire is uniquely designed for modern low profile tire and rim combinations popular on larger high performance SUVs such as the Porsche Cayenne, BMW X5, Audi Q, Mercedes GL, Cadillac Escalade, and Volkswagen Touareg. These are also known as Grandtrek WTM3 without the space.

The main problem with these high performance SUVs is the difficulty in optimizing the tire footprint for snowy and icy winter conditions. All-weather tires do not cut the mustard in snow, slush, and ice because they are not designed with widely spaced tread blocks and fine grooves to bite into snow and ice. In addition, the extra width of performance rubber prevents the tire from biting deeply into the snow and tends to cause hydroplaning in slush and freezing rain. As a result, your standard low profile all weather tires will slip badly or simply float on top of the snow, slush, and ice and completely lose traction.

If you own a luxury SUV or high performance truck or 4×4 featuring large rims with low profile wide tires, you need to either purchase a snow tire specifically designed for the purpose, or replace your entire rim and tire package. Since the latter option is extremely expensive, the best bet is to buy low profile snow tires that fit your high performance application. This is where the Grandtrek WT M3 comes in.

Grandtrek Dunlop WT M3 snow tires offer a directional V-pattern that quickly extricates large amounts of snow and slush from the tread, giving you excellent grip in the snow. Their low profile retains excellent response and feedback you expect from your high performance vehicle. The high silica rubber ensures the tire remains pliable even in the coldest conditions. Customer feedback on comfort, handling, noise, and treadwear has been very strong, meaning these are tires you can get great value from. The tires are V speed rated up to 149 mph/240 kph.

The Grandtrek WT M3 also comes in a Run Flat Grandtrek WT M3 ROF version. Dunlop’s patented Self Supporting Technology (DSST) provides an immensely important safety measure that allows you to drive 50 miles or more on a flat tire. If you have ever gotten a puncture at -10 degrees in a blinding blizzard, you know that you never want to change a tire in those conditions again! So if you’re looking for that extra measure of safety for you and your family, you should seriously consider the Dunlop Grandtrek WT M3 ROF Run On Flat as an option.

When shopping for snow tires for your luxury performance SUV or 4×4 this winter, hopefully these positives and negatives come to mind if you’re considering the Grandtrek WT M3.

Road Trip: Dubai to Jebel Jais

[ad_1]

Jebel Jais happens to be the highest mountain peak within UAE, and is situated the emirate of Ras Al Khaimah, and is a part of the Hajar Mountains. It stands at a height of about 1900 mts (abt 5800 ft) about sea level and is about 30 kms from Ras Al Khaimah city area. The distance from Dubai to Jebel Jais is about 180 kms, and from Abu Dhabi is about 260 Kms.

As you pass the Lantern round-about near the RAK Hospital you need to keep driving towards the mountains where a small board points you to the direction of Jebel Jais. The mountains appear on your left side, till you reach the flat smooth tarmac that leads you to the top. From here it is about 25 kilometers to the top. Google Maps does a decent job of leading you to the spot.

We were a few families, raring to go out for a day trip inside UAE. We wanted to make this a family holiday. We had children and older people in our team and thus needed to find a place which will be accommodating as well as a fun day trip. Jebel Jais came as a new lead and we zoomed on it as our next location. One weekend in March, when the temperature is still fine for a day’s outing in the sun, we packed our whole rations of food, water, snacks and the necessary supplies. Our intention was also to have a grand barbecue there at Jebel Jais..

The drive from Dubai to Ras Al Khaimah was smooth and we took the Mohammad Bin Jayed Road E 311 (Old Emirates Road). Once we reached Ras Al Khaimah we picked up the signs to Jebel Jais direction. Parts of this stretch of about 10 kilometers are on stretches of broken, dusty and slightly rocky unmarked roads. Mind you, the signs are very limited) and from then on it is a wonderful drive mostly on smooth tarmac surface.

Ras Al Khaimah tourism is now actively investing to promote Jebel Jais as a weekend getaway destination in UAE. The Emirate has started building a modernistic Hotel and a para-gliding range in this location.

We were grouped into three cars, including a Toyota Corolla, a Nissan Altima and a Mitsubishi Pajero. Though you may read to be otherwise, it is pretty well possible to use a sedan car in order to reach Jebel Jais. But do not wander offroads, keep to the beaten path if you are driving a non-SUV.

The view in this stretch of 25 kilometers to the top (or almost to the top) is simply breath-taking. Rugged hilltops rise on three sides of you the more you drive into the lap of the mountains, sweeping views of rocky valleys stretch on one side, gorges can be viewed at different directions, and we tackled around eight hair-pin bends till we reached the top. It takes about 45 minutes from RAK city area to reach here. We have driven to most locales in UAE and this scenic drive of forty odd minutes, beats the others hands-down. It is fantastically exhilarating.

As you reach the summit, you will find that the final 5 kms or so has been blocked off (as off March 2015), as the tarmac roads were still being built. It was mostly stretches of rocks and rubble, from the last checkpoint on the route upwards. All along the higher sections of the route, at different turns, there are parking locations and toilets erected for the needy. Again, the condition of these toilets then were not much to be happy about, but it is still an option. The parking spots have been built at advantage points along the route, where it feels great to park awhile and absorb the beauty and serenity of the mountains around you.

The temperature continuously falls as you drive up to the summit, and the drop is by almost 10 degree Celsius if compared to the city down below, and that was a very welcome change. The Jebel Jais summit has been reported to receive quite a few inches of snowfall in 2004 and then in 2009. This is surely the coldest point in UAE.

Once we reached the end of the black armac road where the last checkpoint stops you from venturing further, we turned back drove down for about a couple of bends till we saw this hilly side road. The hilly road brought us to a ridge on the side of the mountains which gave us a great viewpoint along with a little privacy. Over the ridge we could see the sea near the “ghailah” area of UAE at the end of the horizon downwards over the mountains on the other side.

We parked our cars and unpacked our supplies and prepared for our grand barbecue. Mind you, there are no shops or cafes in this route, (as of March 2015). Every drop of water and every morsel of food needed, has to be brought here.The children loved the little hikes over the boulders and embankments around this rocky spot that we chose. Quickly we got our supplies spread out on the mat, and arranged to light up the charcoal grill. There were some waste collection pits around here too. Mats were put on the ground, and the women in our team helped us prepare the ingredients for the grill. In about 20 minutes we had a lovely barbecue fire ready for the grill.Children loved the nippy air, and got busy in their fun activities. The sun warmed our backs amidst the little nip in the air.

The food tasted awesome, charcoal grilling always has this special aroma and brings that exquisite softness in the chicken or mutton that you grill. We had also brought in plentiful supplies of water and soft drinks to quench the thirst for all, and also had snacks to bite on till the grilled food was ready. Then we all sat around and had this hearty meal along with some hummous and garlic paste for the Lebanese wheat rolls that we brought. The atmosphere was one of joy, people laughing, jokes and some mindless fun all along. We enjoyed the great views all around, quiet serene rocky mountains, a rocky valley and gorge in front of us, and great views to the blue Ocean below. The weather was fantastic and it was a time to chill out and unwind from our stressful city lives.

As evening approached, we boiled a hot pot of water to make us some instant coffee. Adults also shrugged out of their lazy bones and had their few moments of extreme wishful fun, tackling extreme rocks and boulders for a better scenic view.The sun set was softly approaching us, causing wonderful myriad of colours on the mountain tops. and the chill increased with the setting of the sun.

With the approach of darkness we could slowly see the lights in the towns below us come to life. The main motorways looked like bright ribbons in the evening horizon while little trinkets of lights came up marking the residential and commercial districts. As darkness fell, we packed our stuff back in the car. Mind you street lights are very few and the parking zones have the lights burning till it was around seven, after which they switched off.

Navigating back down the steep roads and hair-pin bends back into civilizations was guided by the moon. All in all, Jebel Jais is probably the best drive and mountain spot in UAE. It needs more infrastructure at the moment, but it has already become a magnetic attractions to travel lovers in Dubai or in UAE. Visitors or residents alike, if you have a car, do not miss this destination. You would love it!!!

Nissan Engine Range for Nissan Skyline – RB20-RB24-RB25-RB26-RB30

[ad_1]

Nissan Engine Range for Nissan Skyline – RB20-RB24-RB25-RB26-RB30

The Nissan Skyline started the lifespan of the RB Engine line. The Technical Specifications for the Line are as follows:

  • RB20-2 LITRE 1998CC, 78MM BORE, 69.7MM STROKE
  • RB24-2.4 LITRE 2428CC, 86MM BORE, 69.7MM STROKE
  • RB25-2.5 LITRE 2498CC, 86MM BORE, 71.7MM STROKE
  • RB26-2.6 LITRE 2568CC, 86MM BORE, 73.7MM STROKE
  • RB30-3.0 LITRE 2962CC, 86MM BORE, 85MM STROKE

Common letter designations across the range were:

  • D-indicates double overhead cam (DOHC)
  • E-indicates engine is fuel injected
  • S-indicates engine is carburetted
  • T-indicates engine came equipped with factory installed turbo charger
  • TT-indicated engine came equipped with twin turbo chargers

The first of the RB20 engines came in the R31 Skyline in 1986. The first incarnations of these engines had two main variants. The earliest version was dual overhead cam using a NICS (Nissan Induction Control System), this was an injection system with twelve small intake runners, it included a butterfly system that divided the air intake ports for better low end performance. This system was later replaced with a system called ECCS (Electronically Concentrated Control System), this system replaced the twelve small runners in exchange for six larger ones although they still retained twelve ports on the cylinder head, these they divided with air splitter plates.

The different variations of the RB20 through the years were denoted by the addition of a letter code system.

  • RB20E-denoted a single cam variant
  • RB20ET- single cam turbocharged
  • RB20DE-dual over head cam
  • RB20DET-dual overhead cam turbocharged
  • RB20P-another single cam variant
  • RB20DET-R-dual overhead cam turbocharged
  • RB20DE-NEO-dual overhead cam with improved low end torque designed to reduce fuel consumptions and lower emissions.

The RB24 was a very rare engine. It was mechanically made from different engine parts in the RB line. The block was from a RB25DE/DET, the cylinder head was from a RB30 and the crankshaft was from a RB20DE/DET with 34mm pistons. This engine was not injected but came with carburettors. This configuration allowed the engine to have essentially the same displacement as the RB25DE/DET but rev higher.

The RB25 engine was mass produced in four main forms:

  • RB25DE-non turbo twin cam
  • RB25DET-twin cam turbocharged
  • RB25DE-NEO-non turbo twin cam
  • RB25DET-NEO-twin cam turbocharged

From 1993, the RB25DE and RB25DET came equipped with NVCS (Nissan Variable Cam System) this allowed the engine to produce more torque and power at lower RPM ranges than was possible in previous versions. Other changes that were made were the addition of a revised electrical system, the turbo charger on the Rb25DET was changed from an aluminium compressor to a plastic one, the ignition system got an upgrade with the introduction of ignition coils with built in igniters, eliminating the need for a separate coil ignitor. Other changes during this time to the engine were revised engine ecu, new cam angle and throttle position sensors and a newly designed mass air flow meter. Mechanically the engines were identical in series 1 and 2 engines.

The RB26DETT engine was produced throughout 1989-2002 primarily for the Nissan Skyline GT-R. The intake for the RB26DETT varies from the other RB series engines because it uses six individual throttle bodies instead of a single throttle body. It also uses a twin turbo system run in parallel. Both turbo chargers are of equal size and the wastegate is set to limit boost to pressure to 10psi. this engine is known for its strength and power potential. It is not unheard of to see people get 600hp from these engines without any modifications to the internals. Also from a reliability standpoint, these engines regularly hit 100,000 miles and even 200,000 miles as long as it is serviced regularly.

RB26DETT engines produced before 1992 were found to have a common oiling problem. The surface where the crank meets the oil pump was machined slightly too small, this eventually leads to an oil starvation problem and oil pump failure at higher RPM’s. Later versions of the engine fixed this problem and aftermarket performance part manufacturers make oil pump extension drives to eliminate this problem.

The RB30 engine came in the following configurations:

  • RB30S- single cam carburetted
  • RB30E- single cam fuel injected
  • RB30ET-fuel injected single cam turbo charged

The RB30DET engine was not actually produced by Nissan, the RB30DETT demarcation actually refers to a turbo charged engine which commonly had a engine block from a RB30E, this was mated to a Cylinder head from either a RB25DE, RB25DET or RB25DETT, RB20DE/DET heads were not used because of the difference in bore size.

You may be able to find slightly different variations of the above engines, these are commonly made by engine builders with a bit of know how in the field. These engines are used quite often when people are doing transplants into different vehicles and intend to use them for performance applications. The engines are powerful and dependable and are capable of generating huge amounts of horsepower when built correctly.

Limit Test for Arsenic in Pharmaceutical Analysis

[ad_1]

This is based on the reaction of the arsenic gas with hydrogen ion to a yellow stain of mercuric chloride paper. The test is provided to demonstrate that the content of arsenic does not exceed the limit given the individual monograph in terms of arsenic per gram of the test substance.

Potassium iodide used as a lessening agent. It is also known as the Gutzeit test and a special apparatus is required. The limit for arsenic is indicated in the individual monographs in terms of ppm. All reagent used should be as low as a content of arsenic as possible.

Arsenic which is present as arsenic in the taste is decreased to arsenious acidic by minimizing agents just like potassium iodide, stannous acid, zinc and hydrochloric acid.

The arsenous acid is further reduced to arsine gas by hydrogen and reacts with mercuric chloride paper to give a yellow stain.

H3AsO4 + H2SnO2 ­­-­­­­— H3As03 +H2SnO3.

Arsenic acid Arsenous acid.

H3AsO3 + 3H —— AsH3 + 3H2O.

Arsenous acid Arsine

The quality of arsenic present in the same will determine the amount of the yellow stain on the mercuric chloride.

Apparatus.

They consist of a 100 ml bottle of conical flask closed with a ground rubber stopper. A glass tube of about 20 cm by 5mm passes through it.

The lower part of the tube is drawn to an internal diameter of 1.0 mm, a lateral orifice of 15 mm from its tips and 3 mm in diameter.

Procedures for limit test for arsenic:

Introduce the test solution prepared as directed in the individual monograph into the conical flask.

Add 5 ml of 1M potassium iodide and 10 g of zinc AsT.

Assemble the apparatus and immerse the flask in a water bath at a temperature of about 40 deg. C to ensure that a homogenous evolution of a gas is maintained. The temperature may be adjusted to obtain a regular but not too violent evolution of the gas.

The reaction may be increased by placing the apparatus on a warm surface, care being taken for the mercuric chloride paper to remain quite dry throughout the test.

After 40 mins any stain produced on the mercuric chloride, the paper is not more intense than that obtained by treating, in the same manner, 1.0 ml arsenic standard solutions (10 ppm As) diluted to 50ml with water.

Between successive tests, the tube must be washed with hydrochloric acid (250 g/l) AsTS, rinsed with water and dried.

Standard Stain

Obtain by preparation of a solution by adding 10 ml of stagnated hydrochloric acid and (250 g/l) AsTs and 1ml of dilute arsenic AsTs, to 50 ml of water. The resulting solution, when treated as described in the general test, yield a stain on the mercuric iodide paper as ASR, Known as the Standard Stain.

Note

  • Stannous chloride is commonly used for full expansion of arsine.
  • Zinc, potassium iodide are used as reducing agents.
  • Hydrochloric acid is used as a tool to make the solution of acidic.
  • Mercuric iodide papers are used to trap any hydrogen sulphide which may be evolved along the arsine.

Precaution

Arsenic compounds are very toxic and care should be taken when handling this test. It really important and should be aware of this.

What Wheels and Tyres Can You Use on Your Freelander?

[ad_1]

Because a Freelander is a 4×4 vehicle the type of wheels and tyres you use are very important to ensure you do no damage to the drive train.

Recommended Tyre Sizes

The recommended tyre sizes for a Freelander 1 (1998 – 2006) are:

  • 15 inch wheels: 195/80 R15
  • 16 inch wheels: 215/65 R16
  • 17 inch wheels: 235/55 R17
  • 18 inch wheels: 235/50 R18
  • 19 inch wheels: 245/45 R19
  • 20 inch wheels: 245/40 R20
  • 22 inch wheels: 295/30 R22

Although we don’t come across many Freelanders with 22 inch wheels!

For the Freelander 2 (2006 onwards) the recommended tyre sizes are:

  • 16 inch wheels: 215/75 R16
  • 17 inch wheels: 235/65 R17
  • 18 inch wheels: 235/60 R18
  • 19 inch wheels: 235/55 R19
  • 20 inch wheels: 275/40 R20
  • 22 inch wheels: 265/35 R22

What do the Tyre Size Numbers Mean?

Although many of us are quite used to ordering tyres by their numbers, and know they are important, we don’t all understand what they mean.

If we take the 16 inch wheels for a Freelander 1 the tyres should be:

215/65 R16

The first number, 215, is the width of the tyre in mm from side wall to side wall when it is not stressed and you are looking at it from the top. The technical name is the section width.

The second number, 65, is the ratio of the height of the tyre sidewall expressed as a percentage of the width. The technical name is the aspect ratio, or section height. In this case, 65% of 215 mm is 139.75 mm.

The R means the tyre is of a radial construction, this just means the cord plies are arranged at 90 degrees to the direction of travel, or radially (from the centre of the tire).

The next number, 16, is the diameter in inches of the rim of the wheel the tyre is designed to fit on. So in this case it is a tyre for a 16 inch wheel.

It is a bit strange that tyre sizes mix inches with mm, but that’s the way it is done!

When you look at the size printed on the tyre this number, e.g. 215/65 R16, will be followed by two numbers and a letter. The two numbers are the load index and the letter is the speed rating. The load index indicates how much weight the tyre can take (for a Freelander you need a minimum load index of 84 or 85, depending on the exact model of Freelander you have) and the speed rating refers to the speed you can travel at for 10 minutes continuously without the tyre breaking into pieces.

The speed ratings are:

  • Speed Symbol Max Speed Capability
  • MPH Km/h
  • L 120 75
  • M 130 81
  • N 140 87
  • P 150 95
  • Q 160 100
  • R 170 105
  • S 180 113
  • T 190 118
  • U 200 125
  • H 210 130
  • V 240 150
  • W 270 168
  • Y 300 186
  • Z 240+ 150+

Can You Use a Different Sized Tyre from the Recommended on Your Freelander?

Provided the overall circumference of the wheel with the tyre fitted is within plus or minus 2.5% of the recommended then you should not have any problems in fitting different tyre sizes to your Freelander (although the speedometer will be reading slightly inaccurately). The overall circumference is calculated from the overall diameter.

If the overall circumference is more than plus or minus 2.5% then you run the risk of damage to your drive train.

Taking the most common Freelander tyre sizes, here are some alternative sizes you could use:

195/80 R15 alternatives are:

  • 205/75 R15 (-0.87% difference in circumference)
  • 215/70 R15 (-1.70% difference in circumference)
  • 215/75 R15 (+1.47% difference in circumference)
  • 225/70 R15 (+0.32% difference in circumference)
  • 235/70 R15 (+2.34% difference in circumference)

215/65 R16 alternatives are:

  • 225/65 R16 (+1.76% difference in circumference)
  • 225/60 R16 (-1.44% difference in circumference)
  • 235/60 R16 (+0.28% difference in circumference)
  • 255/55 R16 (0% difference in circumference)

215/75 R16 alternatives are:

  • 225/70 R16 (-0.83% difference in circumference)
  • 225/75 R16 (+2.19% difference in circumference)
  • 235/65 R16 (-2.19% difference in circumference)
  • 235/70 R16 (+1.09% difference in circumference)
  • 255/65 R16 (+1.36% difference in circumference)

235/65 R17 alternatives are:

  • 245/65 R17 (+1.64% difference in circumference)
  • 255/60 R17 (0% difference in circumference)
  • 265/60 R17 (+1.64% difference in circumference)
  • 275/55 R17 (-1.52% difference in circumference)

Do remember that if there is a difference in the circumference then your speedometer reading will be slightly wrong.

You can check whether it is safe to replace your current tyres with any other size by using one of the tyre size calculators available, so if you would like to check for yourself then try this tyre calculator.

How Many Tyres Should You Replace on Your Freelander?

It is always recommended to replace all four tyres at the same time on your Freelander, with the same make, model and type, so as not to cause damage to the drive train.

The 4×4 system on the Freelander 1 is very sensitive to differences in the rolling radius of the tyres, and if these differ by more than 5mm you are risking damage to the drive train, particularly to the rear differential.

To check that your tyres are not winding up your viscous coupling unit (VCU) – the bulbous piece in the centre of the prop shaft running from the front to the back of your Freelander 1 – which is the hub of sending drive to the rear wheels, then drive your Freelander for about 5 – 10 miles, then get underneath and check the temperature of the VCU. BE CAREFUL, the VCU can get very hot! If the VCU is too hot to comfortably hold your hand on it then you have an issue with your tyres, and you should look to replacing them IMMEDIATELY – otherwise you are going to have a very big bill for drive train items.

If you do only replace two tyres on your Freelander 1 then make sure the new tyres go on the rear (the same make, model and type as the front ones) AND check the temperature of the VCU, as above, to make sure it is not heating up. Never replace just one tyre on a Freelander.

A Little More Technical Detail on Freelander Tyres and Wheels

For those of you who like a little more technical detail on your Freelander tyres and wheels here is a bit more information.

For the Freelander 1:

  • PCD 5 x 114
  • Offset 35 to 45
  • Bore 64.1
  • Fittings N 12 x 1.5

For the Freelander 2:

  • PCD 5 x 108
  • Offset 35 to 50
  • Bore 63.4
  • Fittings N 14 x 1.5

If you do not understand what these mean, here is a brief explanation.

PCD is the Pitch Circle Diameter. This is the diameter, in mm, of a circle drawn through the wheels bolt holes. It also indicates the number of studs, or bolts, the wheel will have. So the Freelander 1 has 5 bolts and the diameter of a circle drawn through the bolt holes is 114 mm. The Freelander 2 has 5 bolts and a diameter of 108 mm.

The offset is where the wheel will sit in relation to the body line of the vehicle. Offset is usually stamped on the wheel and is measured in millimetres of et (et is the short form of the German word ‘Einpresstiefe’ which literally translates as insertion depth). The numbers are essentially the distance between the centre of the wheel and the hub.

The centre bore of a wheel is the centre which fits over the hub. The bore measurement is the diameter in mm of the centre bore.

The fittings are the wheel nuts and bolts required.

Fix for Sticking Accelerator Pedal at Zero Cost

[ad_1]

This relates to a 2002 Buick LeSabre with a 3.8L engine, but the same general principles would apply to most any car with the same problem, I’d guess.

Occasionally, the accelerator would briefly resist moving when pressed. Then, when sufficient pressure was applied, it would break loose and operate normally. This seemed to be happening more frequently and the pressure required to break it loose became greater.

Time to look at it!

Step one was to remove the plastic shroud which covers the engine. This can easily be done by unscrewing the oil fill spout (the 3-inch extension onto which the oil filler cap fits) by unscrewing it a half turn and lifting it out. This exposed the fuel injector body and mechanism.

By manually working the sector pulley which was activated by the accelerator, I concluded that the butterfly was sticking in the closed position. But how to get at it was the problem!

I removed the rubber boot between the air box and the fuel injector body. But this revealed a “screen” which totally covered the intake!

That “screen” was held in by a “C” ring which I removed next. But the “screen” didn’t come out easily. It’s not a flat screen; it’s a honeycomb piece about 1/4 inch in thickness. It worked best to work it out a little all around the circumference and going around multiple times. I used a knife blade to pry it out, but next time I’d use a wire with a hook on the end to go in and pull it out from the inside.

    I think its purpose is two-fold:

  1. Create a laminar air flow into the chamber, and
  2. Serve as a “heat absorber” or flame suppressor in event of a backfire.

Once that was removed, I could see the butterfly and could pretty much confirm that was where the problem was. I cleaned it up around the circumference, but it still stuck. Then I squirted some AMSOIL MP (sort of like WD-40) into the butterfly shaft bushings.

That did the trick! No more sticking!

How long it will stay that way remains to be seen!

If it fails again, I’ll remove the throttle position sensor on the front of the injector body. That should expose one end of the butterfly shaft, and that was the end which gave the most trouble this time. (This requires a Torx wrench to remove.)

What was the cause? Truly, I don’t know. It acted like there was “old grease” in there which gummed up, but doubt that it was lubricated with grease. Maybe “sticky stuff” in the gasoline over 60k miles?

Soft Key Performance Indicators Are "Mission-Critical" – This is the Way to Develop Them

[ad_1]

In this article we will work through a real example of an operational soft KPI that changed the relationship of a business with its customers. After reading it you will be able to apply a similar thought process to your own business.

Setting target levels of service.

The Business: Specialist auto component repair services. The business had a working KPI model in place.

The Customers: Auto repair firms dealing with consumers and their insurers.So

The service: Pick up of repair jobs, repair in a dedicated specialist facility, and return to the customer.

The symptom: Frequent enquiries and constant complaints about delivery date and time.

The real problem: Jobs queued in order of receipt, regardless of the complexity of the repair. Small simple jobs would wait because they were queued behind large complex jobs.

The first solution: Jobs scheduled to meet a specified day and time of return; complex jobs would be scheduled for a later time. The customer was advised of the return delivery run with the price quote before the job was started.

Did it work? Partially. There was no target level of service, and no measure of performance. It was not linked to the business marketing strategy.

Setting the target level of service: Ask the customers. A quick and dirty phone survey suggested that 48 hours was an acceptable lead-time, because the critical thing was their ability to tell the customer when the vehicle would be ready.

Performance target: An assessment of 2 month’s history showed that around 15% of jobs were complex and could not be reasonably completed in 48 hours. We guessed that 85% might be the right point.

Target Level of Service: 85% of jobs to be returned within 48 hours. This was a promise that no competitor could match.

Performance measure: We predicted that, if the target LOS was achieved, complaints and enquiries would drop to a low level. The complaints log showed that complaints dropped to zero inside 4 weeks of launching the new system and publicizing it to the customers.

The results: Market share increased dramatically as the auto repair industry adopted the new standard and the word got around that the service was reliable.

Internally, productivity rose due to better scheduling. Disruptive enquiries and demands for special treatment were virtually eliminated.

Operating profit increased.

Proof of the Soft KPI

On three occasions over the next 2 years, complaints rose in volume suddenly. A quick check of the level of service showed that it had dropped below 85%. Prompt corrective action restored the complaint incidence to its normal low level.

My conclusion: We were lucky that our first estimate of the desired level of service was correct. If the customers needed 90% then we would not have seen the desired reduction in complaints.

If the customers would have been happy with 75% we could have experimented with that and monitored complaints. If they rose we could move back to the 85% LOS, but we would have upset some customers unnecessarily, and put our goodwill at risk. Also 75% would have been achievable by some competitors, so there would be no competitive advantage.

The 85% LOS worked for everyone, so do not fiddle with a winning formula.

This is a classic “Soft KPI”.

Measuring it does not help you understand what is going on. Understanding what is going on does not help you find a solution without measurement. Both are necessary to make sound decisions.

Setting Soft KPIs

Look out for performance indicators that logically influence business performance but where the effects are distant in time and place from the cause, and where you cannot link into your KPI model using an algorithm.

An example is Labour Turnover. Everyone knows that this is very costly, and that high labour turnover has highly disruptive effects on business performance.

Is Labour turnover a KPI?

It cannot be a hard KPI because you can only estimate the effects on profitability with varying degrees of uncertainty. You cannot build it into your accounting system even though you can find some of the costs eventually buried somewhere in your accounts. The rest of the costs come from loss of something that drives a hard KPI, typically in the way loss of a customer drives a downturn in sales. The reason is that you cannot predict the cost of losing a single good employee, or the extra profit from losing a single bad employee.

It all depends, but on what?

You can correlate labour turnover with profitability, but only over an extensive time period. You cannot define a formula that links labour turnover with a hard KPI with any confidence.

Labour turnover may be a soft KPI but only in some businesses. In highly seasonal businesses dependent on casual labour the costs of recruiting and training casuals are high, can be factored into the budget and managed as a hard performance indicator.

Contrast that with the loss of a key sales person; the value of their knowledge of your business and your/their customers is always hard to estimate and expensive to replace.

So a soft KPI must satisfy some, perhaps all of the following criteria if it is to be useful.

* Clear correlation of the soft with a related hard KPI.

* A metric that enables performance against the soft KPI to be tracked.

* Clear links to either a driver KPI or a “consequence” KPI that can be tracked. Driver KPIs are leading indicators.

* The ability to estimate a threshold that may operate.

* Is it Mission Critical? Does it warn of a potentially fatal error.

Can you fit them into a KPI model?

Probably not. That does not mean that they are not “mission critical”. They must be tracked.

Product safety issues that drive product recalls are mission critical, as Toyota recently found to its great cost. I am sure that Toyota know what their hard product recall KPIs told them after the event but the soft KPIs that could have highlighted the cause of the problem were clearly missing

Threshold effects confuse the setting of Soft KPI targets.

Many cause and effect relationships in business are not a straight-line correlation. In some cases there is a threshold effect at work.

The problem of setting the right level of advertising spending is a good example. We know that in some markets advertising spend has to buy enough space to become visible to customers. Spending below that threshold level, wherever it is, does not increase sales, because below the threshold you are invisible. Above the threshold, results flow in,

In the same way, looking at our service example, setting the target LOS too low would achieve nothing by way of customer satisfaction. Hitting the right number worked like magic.

Places to look for Soft KPIs

Quality and service are essential functions, where mission critical soft KPIs can be found. As I have shown, threshold effects are common. Both hard and soft KPIs are useful in assessment of product and service quality and it is productive to link the two types of KPI.

Project management is similarly dependent on soft KPIs as well as hard measures. The predictive element of project forecasts are inevitably soft because it uses probability measures; critical, but only hard after the event.

In the sales and marketing field measures like customer satisfaction are confused by the challenge of finding reliable measures, and the correlations with hard measures are not as high as we would like. Market share numbers are usually dependent on surveys or industry statistics and these can be quite unreliable.

Employee morale and engagement are clearly important and difficult to measure reliably because the inherent errors associated with opinion surveys confound the results.

You should be alert to the need for leading indicators. These are the most useful, because they enable you to take corrective action before things go off the rail.

Sales forecasts, in fact all forecasts, are soft KPIs, despite being provided as hard numbers. They are KPIs but every forecast should have confidence limits around it so that you can assess its reliability. Forecasts are of course mission critical in most businesses.

Soft KPIs and your management process

Soft KPIs offer huge value to your management process so you should never ignore their existence. It is just that the differences between soft and hard KPIs mean you need a different approach to the way you develop them and the way you use them. If you follow the tips and the thinking process illustrated in the story you will be on the right track to identify your soft KPIs and put them to work.

Hard KPIs are easy to work with because they have one unchanging characteristic; they are mathematically linked to measurable changes in performance of the business.

Soft KPIs are a bit more difficult, because you can identify the reasons for their importance to your processes, but there is no algorithm to define the way they interact with business performance.

When you find the soft KPIs that are meaningful to your customers, you can refocus your staff on the really important things, and transform your business.

Soft KPIs are business or sometimes industry specific so you may find a source like kpilibrary.com useful to prompt ideas.

3 Major Reasons Why Marketing is Important

[ad_1]

Kotler and Armstrong define marketing as “the process by which companies create value for customers and build strong customer relationships in order to capture value from customer in return.” This definition alone can explain why marketing is important, but let’s outline several reasons why marketing should be one of the small business owner’s main priorities.

1. Marketing builds value in your products and services for your customers.

Most salespeople want to know as little as possible to make the sale. Some sales staff needs technical specifications and things of that nature, but ultimately, the less they have to learn the better. This makes sense, because their goal is to make sales. Therefore, marketing has to step in and create value for your customer. If you can not create value for your customers, why will they buy from you? Sometimes they will buy from you once, but will they come back if there is no value?

Many times, business owners don’t capitalize on all the ways they can give value to their customers. They get lost in the production or product concept of marketing and end up with marketing myopia. Marketing myopia happens when a company pays more attention to the product/service than the value or benefits it offers to the customer. You can not let this happen to you. Pay attention to your customers and why they buy your products. People buy a Toyota Prius not only because it saves on gas, but because it makes them fell more eco-friendly.

2. Marketing helps build customer relationships.

Everyone put emphasis on the sales staff when it comes to sales. “If the sales team doesn’t work harder, we won’t increase sales,” but this is not necessarily true. It costs three times as much to obtain a new customer as it does to keep an existing one. This means you need to maintain the relationship with your current customers in order to lower marketing and sales costs and increase sales.

Properly planned and implemented marketing activities are the only real way to build customer relationships. These activities can include a lot of things: loyalty programs, thank-you cards, customer appreciation events, free gifts, and so on. Each company must find a unique way to set themselves apart from the competition while building a loyal and long-lasting relationship.

3. Marketing establishes a brand image.

When you use FedEx for shipping, you know what you are getting: fast delivery, flexible shipping options, and better service than other shippers. Are all of these things true? They may be, but their marketing activities established all of these. FedEx will have to live up to these expectations of their brand, but their marketing department set the customer up with this image.

You must use marketing to establish your brand. Customers need to know what to expect from your company based on your brand image. What kind of products and what types of service will you provide the customer? Let your marketing tell the story and establish your brand.
