A startup PO has limited budget and needs to validate whether their target segment will use a new expense tracking feature. The FASTEST low-cost experiment is:
-
A
Build the full feature in one sprint and measure usage
-
B
Create a fake door test: add the feature button to the UI and measure click-through before building it
-
C
Commission a market research firm to survey 1,000 users
-
D
Ask the sales team to pitch the feature in demos and count positive reactions
