Running Lean: Iterate from Plan A to a Plan That Works (Lean (O'Reilly))

Treat your future feature ideas like experiments.

Most of your time immediately after launch should be spent measuring and improving existing features versus chasing after shiny new features.

A good test for an MMF is to ask yourself if you’d announce it to your customers in a blog post or newsletter. If it’s too tiny to mention, it’s not an MMF.

You can always feel when product/market fit isn’t happening. The customers aren’t quite getting value out of the product, word of mouth isn’t spreading, usage isn’t growing that fast, press reviews are kind of “blah,” the sales cycle takes too long, and lots of deals never close.
