Suppose you do a typo, a simple spelling mistake in your code. What is the cost of the bug?

If it is caught:

• at development environment - 1 min of developer's time
• at code review - Reviewer's time and developer's time .
• at testing environment - Build time, tester's time, developer's time.
• at staging environment - Tester's time, developer's time, testing environment build and re-test time, staging environment build and re-test time.
• at production environment - Tester's time, developer's time, testing environment build and re-test time, staging environment build and re-test time, production environment build and re-test time, bad name in the memory of users who has already noticed the typo.
• by client - Start preparing for another project/job.

Think about it!!!!
