Abstract

Critical Path Method (CPM) scheduling is the hallmark of current project management practice. This paper explains how one practitioner applies the Lean ideal of a “custom product, delivered instantly, without waste” to CPM scheduling. The paper also demonstrates how CPM scheduling and the Last Planner™ System can be complimentary processes that improve crew flow and work flow in a Lean based project management approach. Further, the paper introduces the concept of attention as a wasteable project resource and presents methods for its efficient utilization.
