Small surface. Real software.
The objective is not to maximise feature count. It is to understand the workflow well enough to build the smallest useful product, put it in front of real users and keep the implementation understandable as it grows.
Understand the workflow
Map what happens today, who touches it, where the friction lives and what a genuinely useful outcome looks like.
Build the real thing
Work in short feedback loops around the actual use case instead of spending months specifying features before anyone can use them.
Operate it properly
Treat deployment, reliability, security and maintainability as part of the product rather than work left for later.
