I am building a capacity planning model in Project 2016. My goal is to illustrate that in real life no one does a single task 100% of the time. I want to show that 10% of the resources' time is dedicated to administrative functions (one task, each resourced allocated at 10% for the duration of the time period in the plan). For the project work in the same plan, my example is:
Project 1 has 6 phases (each phase is one task). Design is 4 days. Development is 5 days. Development can begin halfway through Design. Resource allocation for the Developer is:
90% for the first two days of Design (accounting for the 10% admin time). 45% for the last two days of Design. 45% for the first two days of Development. 90% for the last three days of Development.
Project assumes 100% availability for the resource so he appears over-allocated during the days where Design and Development overlap. What is the most effective way to tell Project that there are varying degrees of availability during a phase (again, one task per phase)? I know that I can break the phase into multiple tasks but this is just a capacity planning model, not a real project, and I want to keep it as simple as possible. The project doesn't have to be tied to specific calendar days but the duration needs to be fixed. Thanks!
