I have invented a new way to write software when people who hold decision power are not available. It's called Flag Assisted Programming and it goes like this: whenever you have a question on how to proceed with your development, instead of bothering decision makers, add a flag to the configuration that determines which way to go. Then estimate for all the possible answers to your question and implement them all. This way, management not only has more time to do real work, but also the ability to go back and forth on their decisions as they see fit. Bonus points, FAPing allows middle management to say you have A/B testing at least partially implemented, and that you work in a very agile environment.
