Agile and Defect
“We will deliver defect free software every time.”

“We will deliver defect free software every time.”

Many software company have embraced some variant of this motto. This is the right thing to do … after all who wants software which has bugs. It is an open and shut case – right?

Or is it? … Especially in the context of agile development.

Let us start by asking two stupid question:

  • How do you measure number of defects?
  • When do you consider a software to be delivered?

Standard method of measuring defect is to:

  • Define and freeze the requirement
  • Derive test cases from the requirement
  • Use the test cases to test the software
  • Measure the number of test cases that has failed

Defect free software means all the identified test cases are passed.

  • But from the perspective of the user is this sufficient?
  • How do you draw the line between what has to be explicitly stated and is obvious but not stated?
  • When do you consider a delivery to have been made? After every sprint?
  • Can you ensure that every user story implemented in a sprint is without any defect?

These questions are not rhetorical. These questions need to be answered as in many organization developer performance measurement and even incentive depend measure of defect.
