Scared / afraid
“I don’t report those bugs so the developer won’t be angry at me”
Talk about the mutual expectations and how you can help each other.
(important lesson for scared IT-people ;-)

Early reviews are a much better way to save time and effort than postponing activities to the end of the project! (important lesson for lazy IT-people ;-)

Example: Begin with the end in mind
•What is the most important result of testing?
•The report for the stakeholder (that he uses for the go/nogo decision)
•So…− You don’t start by making a plan…− You start by making the report-template, this defines
what information the testing process should deliver,− And that’s the basis for the plan.
