Three amigos refers to the primary perspectives to examine an increment of work before, during, and after development. Those perspectives are:
- Business - What problem are we trying to solve?
- Development - How might we build a solution to solve that problem?
- Testing - What about this, what could possibly happen?
People holding these different perspectives should collaborate to define what to do, and agree on how they know when it is done correctly. The end result of such a collaboration results in a clearer description of an increment of work often in the form of examples, leading to a shared understanding for the team.
It’s also good practice for to review increments of the product that have been implemented to make sure it’s correct from those different perspectives.
The concept of three amigos intends to balance between no collaboration between people with different perspectives and involving an entire team in discussing all the details of every increment of work.
