In retrospect, missed schedule falls into two big causes: - Unplanned Work - Planned Work That Didn't End Up Mattering A prerequisite to No Unplanned Work is Knowing All The Work. To get from a hypothesis of the work, to a validated understanding of the work, requires there to be Value Delivery, i.e. you've already demonstrated you understand at least institutionally how to get an increment of value delivered into the hands of a customer, which is how you validate that the Work Ended Up Mattering. (Consequently, any work that hasn't been validated by a customer, is actually only hypothetical work, as we have not validated that the Work Ended Up Mattering.) So you want to establish an end-to-end "throughline" as rapidly as possible so you can start iterating and setting up your feedback loops which facilitate work discovery and value validation. Here's the full maturity ladder that I like, trigger warning bigco language, my product management coach actually doesn't like this: https://www.dustingetz.com/#/page/devops%20maturity%20levels https://www.dustingetz.com/#/page/devops%20maturity%20levels
