This week Stack Ranking system shot up to the top of the
news, when two large tech companies, Yahoo and Microsoft, took opposite
stands, on this (controversial) employee performance system. Stack Ranking
is an HR practice that is resorted to, for putting employees into pre-defined
buckets to identify the “C” level workers.
GE Famed Forced Ranking System
Microsoft, that has taken some heat, and has been flayed in
the media for following this practice, announced that it is moving away from
this form of force fitting. Yahoo, on the other hand, decided to adopt this
system and walked
into HR Crosshairs.
These developments added fuel to the fire, reigniting the
debate once again. The question being asked is that whether this system,
introduced by Jack Welch, back in 1980 at GE, is still useful in today’s
workforce environment. Remember that the workforce in US has moved steadily
away from manufacturing. Today it is turning into predominantly knowledge
based force. GE, since then, has abandoned this system of performance evaluation.
Are tech managers up to the task?
There is, of course, plenty of ammunition on both sides to
go on. Some HR advocates take the view that the forced stacking system is
sound, but is not being implemented properly. Others believe that
embracing the system is symptomatic of incompetency
in the middle management, in that the managers are unable to coach
“under-performers.” This highlights the point that often the goals are not set well,
or there is a strong element of subjectivity in evaluation. It is not unheard
of that employees try to game the system where "anyone's loss is your gain."
However, the proponents of this system concede that this should be used only for a short time.
In tech companies this problem becomes exacerbated since
SMEs often rise to the position of managers. More often than not, they have no
training or skills in talent management.
One of the issues with the forced stack ranking is that it
tends to fit the employees on a standard “bell curve” – with a leading edge of
top performers, most in the average “meets the expectation” category, and the trailing
edge of under-performers, who would be on the chopping block.
The “bell curve” is a representation of a “Normal
Distribution” or “Gaussian Distribution” in statistics. Like many things in
life we tend to fit most “occurrences” into a “bell curve.”
Does Talent Follow the Bell Curve?
There is some belief that things in nature follow the Pareto
Principle, or its more popular moniker- the 80/20 Rule. Scientists have shown
that this behavior has been pervasive and, has been observed in both natural and man-made artifacts.
This distribution has been found to exist in place as diverse as in social networks,
biology, urban planning, website visits, political landscape and other sociological phenomena.
The 80/20 Rule: Note the steep fall
This distribution has been recognized
to exist in workplace also, where we all agree that 80% of employees in any
team deliver only 20% of the work.
A typical Pareto curve shows a tall head that drops quickly
and sports a long tail. It has been found that the long tail of a Pareto Curve
persists far longer than a trailing edge of a “bell curve.”
A Company of Super Performers
This does not mean that if a company fires 80% of its work
force and hires instead, few super-workers, it will turn into a
hyper-performing company. We are yet to
see the rise of such a super company that has only the highest performing
employees.
Maybe it is time that the HR Gurus need to consider the
implications of Pareto Principle in workplace, and suggest an alternative
approach to the forced staking into a bell curve. Note that a stacking system
focuses on individuals over the team. The emphasis is growing on work collaboration
where output is often highly interdependent.
The 21st Century workforce that is rapidly
transforming into knowledge workers engaged in a flatter system will demand
such a change. We see than in Generation Y whose expectation at the work place is very different from the one just two decades ago.
Organizations, that are agile at the cutting edge, have a
different problem to solve. In their case innovation drives the growth. This often requires flashes of genius with a
team to do the quick operational heavy lifting. More often than not, innovation is not a big bolt from the blue, but a series of little flashes that need
to be tested quickly and discarded if need be.
In such organizations morale is the key.
Talent usually does not indulge in game playing to beat the staking principle
and, if the atmosphere gets murky they are the first ones to leave.
