Why are some project teams regularly overloaded, while others have extra capacity? How can it be that some employees feel constantly overwhelmed, or their milestones are never achieved on time? Is it due to a lack of skills – or is it a systematic over-planning of resources? Your project employees are not robots. They go on vacation. They get sick. They spend some time chatting with coworkers around the water cooler. There are plenty of other obligations (meetings, administrative tasks, continuing education, etc.) that also takes time away from project work.
This all leads to the question: What is the actual capacity of your employees? What variables and numbers should PMOs use to create a realistic project portfolio, without resource bottlenecks, delays, and employee dissatisfaction? Is there a formula for resource planning?
