Lean PlanDo manual › Insights
Commitment and reliability
Understand the four weekly indicators of commitment and reliability, and how each one is calculated.
Use the Weekly Commitments and Reliability graph on the Overview tab of Insights to see how well your team commits to work and keeps to the plan each week. The values come from the workable backlog numbers recorded every week. See Workable backlogs.
Each indicator is a ratio calculated at the end of every week. Should Do, Can Do, Will Do and Did are the workable backlog counts for the Do week. The Do week is the first week of the Lookahead (the 6-week or 8-week plan where activities are broken down into smaller tasks), where tasks can be committed. It should be the current calendar week.
The four indicators
Constraint Management level shows how well constraints are identified and managed. A constraint is work that must be cleared before a task can be done, such as getting site access.
- Ratio: Can Do tasks / Should Do tasks
Site Readiness level shows how ready the site team is to take up the planned tasks for the week.
- Ratio: Will Do tasks / Can Do tasks
Commitment level (PPC) shows how well the site team keeps its commitments. PPC stands for Percent Plan Complete.
- Ratio: Did tasks / Will Do tasks
Did tasks are counted from each task's allocation to the Do week:
- A task that starts and ends within the Do week is 100% allocated to that week.
- A 5-day task with only its first 2 days in the Do week is 40% (2/5) allocated to that week.
- If the first task is 100% complete and the second is 40% complete in the Do week, both count as done.
Construct Plan Reliability (CPR) shows the overall reliability of the plan. Of all the Should Do tasks in a week, it shows how many were fully done as planned. This tells teams about their performance, plan reliability and commitment.
- Ratio: Did tasks / Should Do tasks
Read the graph
The graph plots the four indicators for each week. The x axis shows each week's end date and its Confirmed on date. Under the graph, candle bars show the maximum, median and minimum value of each indicator. The info tooltip shows the ratio behind each indicator.
