Once it becomes clearer what some of the main driving forces are behind the definition of an API strategy, the next step is to put together goals and objectives that can ensure the initiative remains on track and doesn't derail as it progresses.
The idea is that it should be routine to, at any point in time, take a step back and verify that goals and objectives are (or are on the right path to) being met, and if not, something somewhere could've gone wrong and a review of the initiative should take place in order to prevent further derail.
