Delivered at PMI SCoP's 9th Annual Scheduling Conference, this presentation is an introduction of a new approach which enables a project to undergo iterative "what if" scenarios until a balance between successful acceleration and achievability.
7. // Measuring Project Performance
Baseline Compliance™
◦ Traditional measures include:
◦ Earned value: heavy time investment to implement
◦ Earned schedule: similar to EV
◦ % complete: what does this really tell us?
◦ Ahead/behind baseline: too granular a scale…
◦ Baseline Compliance™
◦ Determine how close schedule is executed against baseline
◦ Measure of change during planning phase
◦ Measure of well the plan is being executed
◦ More than just date comparison
◦ Looks at period-compliance

14. // Case Study
Owner/contractor Alignment
• Houston-based oil/gas owner
• Objective:
• More on-time completion for projects over $250MM
• Encourage more mature contractor schedules
• Overcome “brain drain” in scheduling
• How achieved:
• Mandated contractor Fuse Schedule Index of 75+
• Gave contractor opportunity to self-assess

17. // S1 > S2 Schedule Critique
Sound Basis of Schedule
◦ Validated multiple sub-projects
◦ Test to ensure true path to First Gas
◦ Analysis showed break in path around Early
Works
◦ Fixing this, First Gas moved to the right by 2
months
◦ Schedule cleanse: further 3 months adjustment

18. // GasCom Logic Density™
Planning Consistency
◦ Determine Logic Hotspots™ in schedule
◦ Level of detail was lacking towards the end of
the project – mainly around interfaces &
integration

◦ Schedule Critique Details:
◦ Missing Logic was added
◦ Lags converted to activities
◦ Float analysis
◦ Showed padding of early activities

21. // Float Analysis
GasCom
◦ S1 showed high float in early stage of project
◦ S2 resolved schedule showed the opposite
◦ Early acceleration opportunity went away
Originally perceived opportunity
for making up lost time through Resolved schedule not
