And……

When regular feature work is progressing smoothly

When creating new teams

Deadlines approaching – dev test pairing from the feature team works wonderfully

http://raji.me/ @raji_bh

Slide22

Because it’s a new fad

http://raji.me/ @raji_bh

Slide23

Tight deadlines – testers new to pairing or team

http://raji.me/ @raji_bh

Slide27

And…

Subjective and difficult to prove that it works

Failed attempts can be counter

productive

Not time efficient as 2 people are doing the same task

Try it for a considerable time with different people

Celebrate success stories. This generates

confidence

Compare

it with

pair programming
