The Herfindahl Index covered in the prior post is an excellent way of measuring competition. Sadly it involves squaring market shares. This seems too much math so in the spirit of simple metrics I’m suggesting a new measure of competitiveness; the BPI or The Bendle Panda Index. It makes Net Promoter look complex and Gigerenzer…

Measuring Competiton 1 The Herfindahl Index
The competitiveness of any industry matters. One way to measure competitiveness is the Herfindahl Index, also known as the Herfindahl-Hirschman Index. Competition Changes Market Outcomes Consumers usually get a bad deal in “concentrated” markets. This is because markets with fewer significant players usually mean less competition. This matters to managers too. If you are considering entering…
Net Promoter
One of the most interesting discussions about marketing metrics in recent years concerns the Net Promoter System/Score, (NPS). Net Promoter Net Promoter is very simple. It compares % of customers who give high scores on “would you recommend to a friend?” with % of customers who give low scores. The Net Promoter is just the…
The Problem Of Overfitting
Nate Silver’s The Signal and the Noise has much to recommend it. It is about prediction generally, rather than being focused specifically on baseball or politics where he built his reputation. He also notes challenges with statistical models, specifically the problem of overfitting. The Problem Of Overfitting A problem Silver addresses is the overfitting of mathematical…
CLV And Limited Capacity
Customer Lifetime Value (CLV) is a great thing to calculate. It encourages marketers to take the numbers seriously. It helps finance people see the numerical basis of marketing.

Beating Rivals Should Not Be Your Goal

The technical term is competitor orientation — when your ultimate objective is to beat your competitors. The point is that pretty much whatever your view of business,…
Marketers Prefer Contribution
A couple of years ago teaching introductory marketing I told my students they must have calculations in the final exam. They listened and gave me numbers. My students were mostly aim for investment banking. They thought finance had the “best” numbers and so used these. They gave me some marvellous numbers, e.g., EBITDA and NOPAT….
How Bad Metrics Help
In this post, I will examine how bad metrics help. Something doesn’t have to be perfect to be useful. Often the act of creating a metric, even a bad metric, creates debate/conversations which highlight what we do, or do not, know. Two Scenarios Consider the following scenarios: A) The plan was unveiled in the meeting….
Does Acquisition Cost Reduce CLV? No
Marketing suffers from serious definitional problems which undermine the communication function of metrics. For example, Does Acquisition Cost Reduce CLV? I therefore recommend a step forward; lets all exclude acquisition costs from customer lifetime value (CLV) calculations. CLV Is The Net Present Value Of A Customer Relationship Customer lifetime value is the net present value…
Market Share is Malarkey
Students, teachers, managers, and commentators all love market share. Many think a reasonable business goal is to increase market share. My only question is: Why? To use a Joe Biden word, Market Share is Malarkey. [This was written in 2012, but Joe Biden phrases still work now in 2021]. Market Share Is Not The Same…
