8. Jonathan Japka, PMP8 Critical Path Roles Scheduler  Perform Critical Path Analysis  Present Critical Path Report  Narrative Project Management  Consumer of Scheduler work  Are We Meeting Key Milestones?  What's Driving the Milestones?  Use to make decisions !!!

9. Jonathan Japka, PMP9 Critical Path Goals Use Report and Narrative to make decisions! Story must be clear and concise!

10. Jonathan Japka, PMP10 Definitions Critical Path Method  Creating a logical network of activities  Assigning durations to each activity.  Flowing the network to calculate; Early dates, Late dates, and total float. Total Float  The difference between the late date minus the early date.  Amount of time a single task can be delayed without delaying project completion

11. Jonathan Japka, PMP11 Definitions Critical Path  Path of activities with lowest float and determines the project completion date.  Longest path of activities through a project Wikipedia definition  Is the sequence of project network activities which add up to the longest overall duration, regardless if that longest duration has float or not.  This determines the shortest time possible to complete the project.  There can be 'total float' (unused time) within the critical path

12. Jonathan Japka, PMP12 Critical Path Analysis Process of Identifying the Critical Path Two basic methods Lowest Float  Sort Activities by Total Float  Simple straight forward  Does not work with multiple calendars  Commingles Parallel Paths Longest Path  Follow Driving Predecessor

13. Jonathan Japka, PMP13 Preparation Clean up all open ends  Activities without predecessor  Activities without successor Find with  Report, Filter, and/or Column Warning!!  Activities with just a Start-to-Start successor are open ends  Add a Finish-to-Start and/or Finish-to-Finish  Hard to find, export relationships to Excel

14. Jonathan Japka, PMP14 Preparation Remove “Start On” and “Finish-On” Constraints  Activities have zero float no matter what  Violates logic Use Retained Logic schedule option  Progress override creates open ends Uncheck “Make open ends critical” Clean up Out-of-Sequence errors  Find with Schedule “Log” Report  Driving predecessor can go “through” a completed activity and then hard to find

15. Jonathan Japka, PMP15 Preparation What is an Out-of-Sequence Error? Remedy  Remove logic tie – just wrong, or  Replace with a Finish-to-Finish AB A B Before After update FF x

16. Jonathan Japka, PMP16 Log report ( Error report ) Preparation

17. Jonathan Japka, PMP17 Let's go..... First Method  Lowest Float Isolate Activities with a Filter  Hide Completed Activities  Hide Level of Effort  Hide WBS / Summary Activity Group by Total Float

19. Jonathan Japka, PMP19 Critical Path by Float

20. Jonathan Japka, PMP20 Critical Path by Float Weakness: Multiple Paths Commingled

21. Jonathan Japka, PMP21 Critical Path by Float Weakness: Multiple Calendars

22. Jonathan Japka, PMP22 Critical Path by Float Lowest Float Method  Float is Calendar Dependent  Does not work with multiple calendars A 5 day B C 5 day duration 0 days Total Float TF 6 day 1 day 7 day 2 days Workweek

23. Jonathan Japka, PMP23 Critical Path by Longest Path Identifying Longest Path  From the predecessor window  Find activity with latest finish  “Driving” Predecessor A C B D

24. Jonathan Japka, PMP24 Driving Predecessor

25. Jonathan Japka, PMP25 Critical Path by Longest Path Filter on Longest Path ( P6 global filter )

26. Jonathan Japka, PMP26 Critical Path by Longest Path Does not always work

27. Jonathan Japka, PMP27 P6 Multiple Path Tool From the Schedule window; Options, Advance Choose Milestone you want to evaluate

28. Jonathan Japka, PMP28 P6 Multiple Path Tool Populates field called Float Path

29. Jonathan Japka, PMP29 P6 Multiple Path Tool Display of Multiple Path(s)

30. Jonathan Japka, PMP30 Reporting the Critical Path No Method Seems to Capture it just right Propose a hybrid approach  Use any method; Float, Longest, Multiple  Tag Activity with PATH Activity code Report  Filter by PATH code  Group by PATH code  Sort by Finish, Start

31. Jonathan Japka, PMP31 Reporting the Critical Path Tag Activity with PATH Activity Code  Create an Activity Code called PATH  Populate code with values 1 thru 20 1 = Critical Path 2 = Path 2, etc.  Create Layout with PATH as a column Follow the Path  Start with “Completion Milestone”, Tag Activity  Goto Driving Predecessor, Tag Activity  Use pop up box or right side floating box

32. Jonathan Japka, PMP32 Reporting Secondary Critical Paths This is where you earn your keep!!! Focus on the Here and Now  Suppress activities in future  Look ahead filters Eliminate Parallel Path for Clarity  Remember it’s a tool for decisions Sometime highlight for discussion  Problem Area’s

33. Jonathan Japka, PMP33 The Skill Part  Tag and Goto Driving Predecessor Activity  Follow Branches Follow “Path” until  Reach a completed activity  Reach an in-progress activity  Reach a Start Constraint Review Report  Paths make senses?  Change Order ( change tag )  Remove ( delete tag ) Reporting Critical Path(s)

34. Jonathan Japka, PMP34 Presentation with Primavera P6 Define PATH activity code

35. Jonathan Japka, PMP35 Presentation with Primavera P6 Layout Grouped by Float with PATH Column

36. Jonathan Japka, PMP36 Presentation with Primavera P6 Tag Activity with PATH code

37. Jonathan Japka, PMP37 Presentation with Primavera P6 Find and GoTo Driving Predecessor

38. Jonathan Japka, PMP38 Presentation with Primavera P6 Open Layout Filtered and Grouped by PATH code

39. Jonathan Japka, PMP39 Closing Avoid Pit-Falls  Use Retain Logic  Clean up Open Ends  Clean up Out of Sequence  For parallel Do not use negative lags Use SS and FF with positive lags  Do not use FS with a lag Replace with activities  Do not use On or Mandatory Constraints

40. Jonathan Japka, PMP40 S-Curve – Bonus Round

41. Jonathan Japka, PMP41 S-Curve

42. Jonathan Japka, PMP42 S-Curve Simple Copy / Paste  From P6 Layout  Enter baseline dates  Copy / Paste into Excel data table  Done! Primavera P6 Setup  Set up Baselines  Create Start and Finish UDF  Remove Actual A with Global Change

43. Jonathan Japka, PMP43 S-Curve – Baselines

44. Jonathan Japka, PMP44 S-Curve – UDF’s

45. Jonathan Japka, PMP45 S-Curve – Layout with Columns

46. Jonathan Japka, PMP46 S-Curve – Global Change Issue: remove that A at the end of the date

47. Jonathan Japka, PMP47 S-Curve – Layout with Columns

48. Jonathan Japka, PMP48 S-Curve – set up Excel dates
