This is a good strategy, imo. I was following it for almost a year and I was having a blast working in a startup. Then a new manager came along and started to dictate how things should be done without much input from the technical team. I kept fighting for what I thought was good for the product instead of aligning with him. In the end it was just too stressful (the manager was not only an idiot but also rude). I resigned, but I wouldn't have done any other way. I simply can't be made to do dumb things from uncurious people.

It's a shame when resigning is the only way out. Before reaching that point, the usual strategies should be attempted:

  Picking your battles;
  Negotiate rather than fight;
  Be better at analytics and research than anyone else. So you have the data to measure or predict success about a particular feature or direction. 
  Armed with your data, you must carefully communicate findings without shaming others. 

It's a fine line between fostering a positive work environment in the face of misguided decisions, and being condescending or derisive towards other team members. There is no silver bullet, but a touch of self-deprecating humour never hurt. If you advice isn't taken, you'll have a non-snarky receipt. Any email written with an irritated tone, will look twice as bad months later.

I did create benchmarks and simulated impact following different scenarios (including the one I was advocating for). Unfortunately that was received in deaf ears. Even worse, actually; they thought I was being too pushy by adding the scenario I was proposing to the analysis. At this point I knew I had to leave.
