Right first
time is wrong
by Phil Cohen
Most popular movements
are built on slogans, and this is just as true of management revolutions
as it is of political ones. Slogans are a little like sugary caffeine-laden
soft drinks: there's an initial hit, but it wears off after a while and
leaves a sour taste.
One of the most misleading catchphrases in the quality management vocabulary
is "quality is doing it right first time". In fact, quality
isn't.
Quality assurance, for example, is about setting up systems to make the
work you do more repeatable, so that even if you're making mistakes, at
least you're making the same mistake each time. The point, of course,
is that you can correct the mistakes once they're repeatable; unrepeatable
mistakes can never be corrected. Quality assurance will eventually lead
to a system in which mistakes have been eliminated - but nowhere near
first time.
In fact, the existence of imperfections is assumed as part of the ISO
9000 model for quality assurance systems. Much of the text of the standard
deals with the handling of defective product, corrective action and so
on. Without imperfections, how can there be improvement?
The implication of the slogan 'do it right first time' is that by putting
more effort into their work (and this must, after all, be the aim of such
a slogan), the people involved in the system can somehow make product
which is perfect. The message is that the problem lies with the people,
not the system they work in. In fact, the opposite is the case: even in
sales, motivation is not a good predictor of success; what's left must
be the system in which the person operates, and the tools and methods
they use.
Now let's look a little closer to the concept of 'right'. How right is
right, anyway? If the product you're producing meets your customer's specifications,
is it perfect? Dr Genichi Taguchi would say not; he pointed out that there
is always variation present in any system, and that that variation is
always a bad thing. An often-quoted example is the width of car engine
pistons: if they are within tolerance, are they perfect? The answer is
no - slight variations in width will cause either excess friction (too
wide) or poor fuel economy (too narrow). The point is that it's only by
making pistons more and more accurately that the quality of the product
can be improved - and they will never be perfect. There never be any such
thing as 'doing it right'.
The late TQM guru D Edwards Deming set as one of his 14 points the command
to "eliminate slogans". His point was that motivating people
without giving them the tools to do the job properly will only dismay
them. Similarly, telling them that 'quality is in your hands', or 'do
it right first time' will have no effect on product or service quality,
and will only provide discouragement.
So what do you use in place of slogans? Give people the tools - quality
assurance to stablise systems, TQM to generate improvements - to actually
improve what they do on a continual basis. Stop blaming the workforce
for their mistakes, and start blaming the system they work in; its artificial
barriers, limited resources, nonsensical restrictions and lack of concern
for the customer.
