Looking for fundamental best practices. How to design, how to get useful customer feedback, how to be responsive and quickly iterate. I know it's a huge topic. Looking for great starting points. I'm a veteran and MBA teaming up with another vet/MBA to make breathing masks (health care, shooting ranges, motorcycle riders). Validating cost structure now and then first target market. Considering form factor, fashion, design.
Great question! Here are the basics:
The Lean Startup by Eric Reis
Running Lean by Ash Maurya

The Startup Owner's Manual by Steve Blank
Lean Customer Development by Cindy Alvarez

When in doubt, **stop debating**. You are not your customer. Get out of the building. Don't build unless you're testing what you build, and ready to throw away what you build when you get answers.
Good luck! Books are helpful as background, but for specific advice on where you and your company specifically should invest time, set up a call with me.
