Scheduling: CPM, PPM & Lean

Project schedules are the lifeblood of any company. Tell me your project schedule and I'll tell you what kind of company you run, your cashflow, the personality of your superintendent, the effectiveness of your team, and the success of your organization. Schedules are the great revealers. They're the great equalizers. Schedules dictate installation, sequencing, production rates, crew sizes, cashflow, milestones, expectations and more. History has remained the same on this point, construction companies live and die by the schedule. 

As technology continues to evolve, the ways in which a superintendent can capture and communicate project timelines have improved as well. And the three main ways in which the AEC is managing scheduled work is through a) the Critical Path Methodology, b) Project Portfolio Management and c) Lean Planning.

Critical Path Methodology, or CPM, conveys a sequence of work organized by a list of activities that dictate milestone completion.

Project Portfolio Management, or PPM, looks and analyzes a complete project schedule based on key characteristics. 

Lean Planning, usually incorporating Last Planner® methodologies, is designed to produce predictable workflow and rapid learning.

In this section, Blue Collar Labs explores the solutions within the Scheduling Workflow that include construction planning, sequenced work, critical path, long-path, resource allocation, pull-planning, PPC, cashflow, inoperability, workforce, work visualization, crew scheduling, gantt charts and more.
