You don’t need Testers – Or do you? | Thursday, April 19, 2012 |  ]

It doesn’t matter how you are working, what method you follow – Agile or Waterfall doesn’t change the need for testers. If you’re moving fast and light, testers need to adapt to the pace and to the way that they get and share information. That’s ok. Good testers can do that.

I hope that the testers will find any important or obvious bugs before customers do.

Without testers, not only do you put out code that you shouldn’t with bugs that you should have caught – you also lose a lot of important information about how good your software really is and what you need to do to make it better. If you care about building good software, this is an opportunity that you cannot pass up.
