Why did you choose X?
Including a technology selection section in your software architecture document gives you somewhere to document the decisions that went into choosing or not choosing technologies. It’s often useful to have a summary of these decisions so that they can be referred to later in the project.
- Is it clear why the selected technologies were chosen?
- If there were options, why were they not chosen?
- Do they all fit in with the constraints outlined previously?
- Are all software and hardware tiers covered?
