88. You can't be half pregnant

A feature cannot be released when it is not ready. It is either ready to release, or it is not. There is no half way line. A feature can't be half ready, just like you can't be half pregnant.

Developers usually work in two-week cycles, when they are focussed on a specific set of tasks. For example, in a two week period, developers may be working on a specific feature for an app. Then they release it, and start on another feature.

Since what developers do affects the rest of what the product team does, this lesson is relevant if you want to work with other people in the product team, like designers, community managers and data scientists.

Corporate accelerators for technology start-ups, which are ran by people who have never worked in a tech start-up are a very risky use of your time.
