You tried Net Promoter® and it didn’t work: Here is where you went wrong

Get the Business Leaders’ Practical Guide to Implementing Net Promoter

On occasion I speak to people who have tried the Net Promoter approach but it failed and they canned the whole project. After discussing it with them I find it always comes down to just a few reasons.

So if your Net Promoter project failed, or it’s looking a bit shaky, look down the list to find out what happened and fix it now.

You made it a Market Research Project

There are plenty of good market research approaches out there but Net Promoter is not one of them.

As a transactional customer feedback tool, NPS® excels. It helps you to uncover current high impact customer issues and how to fix them.

Customers responding to transactional surveys will tell you that you failed to deliver your widget to them on time, or that your web check out is too hard to use. They will tell you exactly where the problem is and often how to fix it.

However, it is not market research and it will fail if you try to make it do that task.

You tried to explain every change in NPS

We’ve all seen them. The chart showing the NPS target for the month, the gap to actual and the attempt to post-hock justify the difference in the chart comments.

Just don’t do it. This doesn’t work for two reasons.

Statistical noise

Net Promoter has some curious features and care needs to be taken to be sure you really know when a change has occurred in the Net Promoter score.

What looks like a change may just be statistical noise and not worth commenting upon.

If you are reasonably sure (95%) that a change has occurred you may run into the second issue.

Many things impact on NPS

Tracking exactly what has impacted on your score is not like doing the variance report on the last widget production run.

A single factor, like Bob in shipping being off sick this month, is not likely to drive a change in your score. The items that might impact on a single month’s NPS are many and varied and you cannot always link changes to specific external factors.

(This is not always true, some of our customers see distinct seasonality in their scores as annual factors drive the score up and down. In this case the are quite sure that those factors are driving the score)

However, you should still chart you score but focus on the trend. The trend is your friend. Look to see how the score is moving over time. Is it generally increasing or decreasing?

You tried to make it a discontinuous innovation tool

I’ve talked before about discontinuous and continuous innovation. Net Promoter is a very good continuous innovation tool. It can help you to make continuous changes to your business to improve customer loyalty.

What it does not do so well is discontinuous innovation: coming up with the automobile, iPAD or Walkman. I say “not so wel”l because recently a customer told me that they estimate that 1 in 1,000 customer comments is the gem of an idea for a discontinuous innovation opportunity.

You collected scores but did nothing else

Your’e collecting NPS week after week, month after month. Did the score change? No! Well of course not. Weighing a pig doesn’t make it fatter.

It is not enough to add a the “would recommend” question to your current customer survey. You have to collect the score AND information on why customers gave you that score AND you have to make some changes in your business.

This is the real key. NPS is just a way of identifying where you are up to.

To improve the score you have to make change within your organisation and it is only the qualitative feedback, and perhaps scored attribute questions, that can help you to do that.

You didn’t do any root cause analysis

Okay so you’re knee deep in data and you’ve got verbatim customer comments flowing down the sides of your desk. So what.

Now you have to make sense of all that data and do some root cause analysis. To do that you probably need to use some quality system tools like “The Five Whys“.

You never worked out how much a Promoter is worth

You collected some great data and performed a really excellent root cause analysis process. The result was a terrific opportunity to improve the NPS but management would never sign off on the funding because you couldn’t justify the ROI.

Did you calculate the value of a Promoter and factor that into your business case? Often it is not difficult to do this calculation — we published an example of how to value a promoter.

The trouble is that without this piece of information you will be hard pressed to make any business case watertight.


So did the reasons you quit turn up in this list or was it some other issue? Either way please let me know your experiences in the comments below.
