This week we have had all our presentation done already, and Qian and I were responsible for the topic "Promotion and Firing Policy".
GE has a vitality curve, which differentiate people into three categories and our presentation is to find out the logic and validity behind the vitality curve in light of Deming's system of profound knowledge and discuss the likely impact on employees.
For people who don't understand what the Vitality Curve is, it basically differentiates people into three categories, the top 20% are A players, the Middle 70% are B players and the Bottom 10% are C players. For the A players, they will get promotions, bonuses etc, whereas the C players have to leave the company.
There are a lot of critics about false ranking, first, it can be subjective, and might be bias. Second it just simply cannot be fair for the C players, because they might not have done anything wrong, but because they are in the lowest 10%, so they lose their jobs.
Deming's philosophy is about fairness, no reward for the winners and no penalty for the under performers, since there are variations in the system. today, for those that perform well it doesn't mean they will perform well next time, and the same for those that under-perform, if they didn't perform well today it might not be their fault, but some externalities, such as the machinery, wrong methods etc...
After the other team presented their understanding about false ranking, I thought I should raise the question that if false ranking has so many critics, why are there still so many companies using it? for example, GE, and why it seems the vitality curve works well in GE. I think the question I was asking was also what we are required to acheive from the mini project that is to find out the "Logics and Validity".
However, I think I was misunderstood by others. I never said GE's success was build on the vitality curve. What I am saying is the Vitality Curve is a part of the organisation and as a successful company, GE seems to works well with it. All I want to ask is why?
I suppose in my own presentation, I answered myself, that is using Jack Welch's words, "being transparent and being honest" and also in conjunction with a performance system including the 360 feedback and Session C meeting, etc
Deming will be against the idea of the Vitality Curve, since it not only punishes the low performers, but also creates fear in the working environment. there are also examples showing that false use of the Vitality Curve can lead to disastrous results. However, can I say GE is a successful example that is using it? is it Valid? I don't work for GE, so I don't really know.
There will definitely be more competition than cooperation, but on the other hand does it encourage winning and doing a good job?
The society we are living in is competitive, right? if not, why do we always talk about "improving competitiveness" for a company?
If everything is fair, why do we need to work hard to get at least a 2:1 degree so we can get a good job? why is there high un employment?
If ranking systems are so bad, and ranking people is one of Deming's 7 deadly diseases, why are so many companies still using it?
I am just simply asking questions, doesn't mean that I am a big fan of false ranking, because I am not, I know it is unfair and all the other shortcomings, I have done my research.
