I have bootstrapped my own company, and so far things are moving along. However I struggle with something that I am not entirely sure how to solve.
The book "Lean Startup" recommends testing every new feature, and the feature's impact on cohorts. For example:
I want to implement social login on my website
My hypothesis is that social login will increase user sign-ups
I can validate the hypothesis over a specified time period (say, two weeks)
If sign-ups as a percent of total visits increases, then the experiment is true
I have one developer who finishes features that I lay out for her. Ideally, I would be getting feedback from users who are providing me with features that I should be building. I want my developer to have consistent work, so I come up with features that I think may be useful, but have no backing behind customer input.
How do I create a system where I can give my developer user-driven features, or do I just have to rely on gut feeling for features to be tested later?
