NVA - Defect or Rework

In my previous post I talked about customer value add and talked about non value add (NVA).
D.O.W.N.T.I.M.E is the word I used to talk about waste. The first one in the downtime is Defects or rework.

Customers don't pay us for rework. They don't expect defects and when they do find defects they are unhappy. To increase customer satisfaction we have to focus on preventing defects.

What can we do to reduce defects and rework?

Its "self certification".

If I can certify my work then I can reduce the number of defects that escape. If business analysts make sure their requirements are accurate, software engineers make sure their code is unit tested and software testers can make sure they have good coverage during testing there are chances of fewer defects will escape to the customer.

To reduce waste and create more value to customer lets start looking at our work and see how we can reduce rework and defects. We can do this one step at a time.
