The company began using Lean principles in 2018 to increase efficiency, improve quality, and enhance collaboration on a major hospital project. The Last Planner System was the first Lean tool that we used on our journey. By restructuring our early project coordination process, we were able to bring in our trade partners’ employees most engaged in the project. Conducting collaborative scheduling meetings prior to the start of specific milestone activities, the WMJ Project Team and the trades work together to review activity sequencing, durations, and manpower needs while discussing any constraints preventing work from starting.
Conducting these collaborative meetings, also known as Pull Plans, allow trade partners to weigh-in on the activity sequencing and scheduling, in turn decreasing the overall project duration while increasing quality.
The Project Team uses the activity milestones shown on the project’s CPM schedule as the start and stop activities for each pull plan session. While considering their needs for each activity and obtaining buy-in from one another, the trades use their experience and knowledge to build the schedule.
