A new Book The Incremental Commitment Spiral Model: Principles and Practices of Successful Systems and Software, is now out.
From another source The right principles trump practices everytime - Dean Leffingwell.
This notion that practices and processes can be put forward in the absence of testing them against principles has become popular.
The most visible of course is that decisions can be made in the absence of estimating the cost and impact of that decision. The principle of MicroEconomics of Software development was first stated by Dr. Boehm. Early in that #NoEstimates discussion was a comment that all those ideas are old and no longer applicable. Of course that ignores the principle of Microeconomics along with most every other principle of managing projects while spending other peoples money.
As well there are other principles of project success
- What does done look like in units of Effectiveness and Performance?
- What is the Plan to reach Done on the needed date for the needed cost?
- What are the resources required to reach Done?
- What impediments will be encountered along the way that must be handled?
- How are we going to measure progress toward Done in units of measure meaningful to the decision makers?
Here's how to develop the answers to those Principles questions.
