1Critical Path Analysis One Way to DevelopTop 3 Critical PathsAngelo Arcoleo18 May2011
2Purpose – This presentation describes one way to analyze total slack and develop a projects’ Top 3 Critical Paths. (There are several other ways….) Essential steps include: 1- Selecting your program end-deliverable as your Primary Critical or Driving Path end-task. 2- Setting a temporary deadline on that end-task, 2 months earlier than contract end-date. 3- Performing Total Slack analysis to determine remaining Critical or Driving Paths. 4- View Top 3 Critical Paths.

4Using Gantt Chart view, select end-deliverable task 1- Select your program end-deliverable as your Primary CP end-task.Using Gantt Chart view, select end-deliverable taskto define Primary Critical or Driving Path
5Use the ‘Find Path to Selected Task’ icon to run macro and find controlling predecessors
6Use the Driving Path Widget to find controlling predecessors The Driving Path Widget locates all predecessor tasks that drive a specific task. Have you ever looked at a long list of predecessor tasks in a project and wondered which one is causing the schedule delay? With the Driving Path Widget, you will stop wasting time manually checking tasks to identify a path of predecessors that determine any given task’s schedule. Just select a task and push the "Driving Path" toolbar button.Available from: Project Widgets
7Select Yes when warning pops-up. Four fields (2-Text, 2-Flag) are used in this macro;Then select View 09 - Path Gantt Chart to view resultsFYI: Here’s what these fields are titled…
8Use View 09 – Path Gantt Chart, to see path leading to that task Sort byDP,Then byFinish
9Select PS-UID Column in MS Project Copy and Paste into Excel for DP numberingthen Copy DP # and Paste into DP field09 AngelosubsystemDriving pathstepSmart DP numbering helps to define subsystem, automatically define DP/CP and sort tasks in sequential order
10Add Formula for CP, if missing… CP will populate as a function of DP 09 AngeloIn a Master Shell environment, using a subsystem prefix in DP field helps identify what subsystem a paths lies.
11Review and adjust DP order to eliminate schedule “knots”, then Sort by DP, Then by Finish09 AngeloSchedule “knots” are out-of-sequence tasks. Manual renumbering smart DP ID fixes this situation.
12Set task Deadline: 2 months earlier, 2- Setting a temporary deadline on selected end-deliverable task,2 months before contract end-dateSet task Deadline: 2 months earlier,to create a negative TS condition…09 AngeloDeadline can be set earlier, depending on the level of “sensitivity” you want to temporarily “push” TS.

15Copy PS-UID for Secondary Critical or Driving Path, Paste in Excel and Number Driving Path09 AngeloReview and adjust DP order to eliminate any schedule “knots”,Sort by DP, Then by Finish
16Define Tertiary Critical Path You may need to further “push” the deadline to define 3rd DPYou can manually number DP for short paths09 AngeloReview and adjust DP order to eliminate any schedule “knots”,Sort by DP, Then by Finish
