Agreed. It’s not hard. Maintain a priority list. Always work on what is #1 priority. If #1 priority is blocked then work on #2 priority. I've described this same approach as "risk driven development." Identify the highest risk to an effort's success, address it, then the next highest, etc. If, during this process, a newly discovered risk is identified as being more than what is currently being worked, put the new risk at the front of the queue and address it. This drives risk to 0, which drives the probability of success to 1. And as you succinctly stated: It’s simple. It works.
