Integration 4D – WHAT/WHEN CPM – WHAT Pull Planning – HOW LBS – WHERE 16 th LCI Congress | San Francisco, CA | October 7-10, 2014
CPM-the WHAT Provides planned work breakdown structure, with key milestones Typically created in Push manner Created early in process CPM – P6 Schedule 16 th LCI Congress | San Francisco, CA | October 7-10, 2014
LBS-the WHERE Identified in P6 where Remaining Durations should be Modified to account for real world production Helped Create a Better Master Plan Provides “should start” dates rather than CPM – P6 Schedule CPM early start or late start dates Ensures continuous work between locations Identified bottle necks & inefficiencies 16 th LCI Congress | San Francisco, CA | October 7-10, 2014
PULL – the HOW Communication – Trades; Last Planners of the Work Create Daily Measurable Detailed Used CPM Milestones to Tasks and then held the Trades Create 3 to 6 Week Detailed accountable Schedules CPM – P6 Schedule Actuals in P6 would Reflect the Promises Kept by the Trades Flushed Out Field Conflicts Pull Planning and Issues Prior to starting the work 16 th LCI Congress | San Francisco, CA | October 7-10, 2014
