Project research lens
3 checks
Do not start from the feature list. Start with the job, then the packaging, then the sharpness of the wedge.
1
Start by asking whether it solves a clear, repeated, monetizable user job.
2
Then inspect the docs, demo flow, and default experience to see if the product is already packageable.
3
Only then ask whether you can reorganize it around a narrower wedge and a faster value path.
