Many organizations are experimenting with different operational models to sustain a strong testing team with various business challenges they are facing. I am sharing my observations made in entire journey as software professional. Each model attempted had its own issues and challenges. It is important that organization attempting any of this model to aware of these potential issues and take necessary steps to counter them.
Effective test process and long sustenance of test engineers were observed more in the case of “Independent testing team under Test Manager” model. Test engineers started seeing career path for their growths. Test process improvement initiatives focused at organization level than project level.
