Higher Scores Aren’t Always Better: Percent Planned Complete (PPC) Example

Construction is full of competitive personalities - more is always better. This is not always the case, and you must be careful when setting targets that your goals don't have unintended consequences. Percent Planned Complete (PPC) is a perfect example.

Percent Planned Complete (PPC) is a critical measure of a weekly work plan or SIP (Short-Interval Plan). 

David MacNeel from On Point Lean describes that higher scores aren't always better in this interview with Felipe Engineer-Manriquez on the EBFC (Easier, Better, for Construction) Show (4 minutes starting at 0:20:00)



54% was the average amount of weekly tasks that got completed as planned when Greg Howell and Glenn Ballard first studied the problem in the late 90s. 

Low to Mid 70s: Likely on-track with schedule and productivity (Two Key Results for Project Planning)

High 70s to High 80s: Likely ahead of schedule and productivity targets. 

High 80s to Low 90s: Great team and conditions.

Mid to High 90s: Likely gaming the system - sandbagging or misreporting. 


An important part of your scorekeeping process is setting appropriate targets with tolerances and clear management escalations if there are large variances, or they are trending in the wrong direction for too long.

What is Lean
Labor productivity in the construction industry impacts all contractors and project owners and has become even more challenging with the craft labor shortage.
Setting Standards and the Feedback Loop
Set the standard. Train to the standard. Certify to the standard. Plan the work to the standard. Execute to the plan and the standard. Check against the standard. Make prioritized improvements to the standard, training, planning, and execution.
Lean Principle - 8 Categories of Waste
The first step in improving labor productivity in construction is improving everyone’s ability to see the waste. Waste can then be broken down into 8 major categories. Like colors these are often interrelated.
