Critical Path or Longest Path

Updated: Aug 24


Critical path or Longest path - challenged and explained



Critical Path or Longest Path? The document "Longest Path Value" by Ron Winter discusses the limitations of using Total Float for scheduling and introduces the concept of "Longest Path" as a more effective metric.


It critiques traditional Critical Path Method (CPM) scheduling, highlighting issues with float calculation and proposing a shift towards identifying and analyzing the Longest Path in project scheduling.


The paper suggests methods for calculating the Longest Path Value, addressing challenges like sequencing, constraints, and the integration of activities with different calendars.


It emphasizes the importance of understanding driving relationships between activities and proposes using "slack" to describe the flexibility within these relationships, ultimately aiming to improve project management through more accurate and insightful scheduling techniques.
