A couple of points I learned from Lean Startup book:
No need to deliver on time things people ignore.
Customer insight is key. Validate their feedbacks, testing what you think they want, and then adapt your product / solution.
In a nutshell: build, (and immediately) mesure, learn.
Mesure innovation success measuring amount of customers using it and revenue generated.
Do not build features, build customer stories.
It seems like a poor sum up. But it's huge.
This book is, of course, great for startup managers but it's also great for any people creating and offering stuff.
I leaned amazing concepts for work and even for life.
