INTRODUCTION TO PULL PLANNING
XXXXXXXXX
Current Scheduling Process
Work expands to fill the time allowed Work flow (hand-off) is not reliable Work production is not steady Dates and durations are determines by few Traditional methods of how work, information and
material are processed needs to change
What is Pull Planning?
Working from a target completion date (milestone) backward, tasks
are defined and sequenced so that their completion releases work
How does Pull Planning Work?
Work tasks, information flow, and material deliveries are planned based on the request (or “pull”) of downstream customers
Pull scheduling will often expose the need for smaller batches, just in time delivery, improved leveling of resources, and reduced lead times
Workflow becomes more reliable and efficient as the waste of waiting, redundancy, and over-processing are eliminated
Pull Planning Step
1. Define the phasing of the work 2. Determine completion dates for the phases (or
milestones) 3. Using team scheduling and sticky’s on a wall, develop
the network of activities required to complete the phase working backward from the completion date
4. Apply durations to each activity with no contingency or float in the estimates
5. Re-examine logic to try to shorten the duration 6. Determine the earliest practical start date
Pull Planning Step continued
7. Decide what activities to buffer or pad with time contingency Which activity durations are most fragile?
What are the risks?
Rank order by degree of uncertainty
Allocate available time to the fragile activities in rank order
8. Is the team comfortable that the available buffers are sufficient to assure completion within the milestone? If not, either re-plan or shift milestone as needed and possible
Milestone or Phases
Sticky Format
Sticky Wall
Pull Planning Rules
All work shall be clear as to content, sequence, timing and outcome
Every connection (hand off of work) in the work stream must be direct and there must be a clear way to request action and receive a response
The pathway for production must be simple and direct Tasks and completion dates must be negotiated with
“performer” and “receiver” No one can assign or move another persons sticky
Now What?
Transfer sticky’s and commitment dates to: Work Register (design phase) Last Planner System (construction phase) Other specialized software available
Monitor progress and task completion through Check-In sessions or Daily/Weekly meetings
Adjust commitments or tasks as needed by Re-Pulling if needed
Work Register
Last Planner System
