Hi: Here is an idea. We create a support demand plan that models the percentage of time people spend doing work that isn’t easily modeled in a project plan. Some people are allocated (Calculated Work) 10%, some 100%, depending on what their role is. Then, we create plans that model work - but we can’t predict if/when people will be doing that work. This includes work to provide production support and specific ad hoc work, like meetings. We do not plan hours for people to do this work, because the plan for that time is found in the Support Demand Plan. People do, however, charge time in their timesheet to these support plans/tasks/line items. That way, we see the demand for their ad-hoc labor through the support demand plan, and we know where they actually spent their time by looking at their timesheets. Over time, we compare the amount of time charged to support/ad-hoc labor and the allocation in the support demand plan. We adjust it to align with a couple month running average. That improves the accuracy over time. Does that help at all? Thanks, Eric
