Set it up correctly at the start
A precision manufacturer launched their first Agile project to develop new machine control software. NVP Software Solutions was called to provide the testing of the project. Starting with no processes, NVP set up a testing environment, identified and acquired a testing tool to complete later testing and coordinated the testing to a successful conclusion. The organisation is still using the test plans and test processes as defined and have expanded their use of the Agile methodology to most of their projects.
The effort involved in getting processes correct at the beginning is frequently underfunded or ignored. However, it does pay back in the long term.
