I just posted a new article: “What is the Most Important Metric of Critical Path Analysis?”
The article starts by differentiating between CPM scheduling and critical path analysis, pointing out that the latter is relevant in optimizing the value of the project investment no matter how the schedule was originally developed. Then it goes on to show why those little known metrics, critical path drag and drag cost, are critical to critical path analysis.
You can find the article here. [1]
