Project Manager Span of Control: Estimate project-manager capacity from project complexity and available management hours.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Project Manager Span of Control to answer this question: estimate project-manager capacity from project complexity and available management hours? Enter Active projects, Management hours per project per month, Productive project-manager hours per month, and 2 other inputs; the calculator shows Required project managers. Try changing one number and watch what happens to Required project managers. The answer tells you Required project managers.
Age 15Explain it to a 15-year-oldConnect it to the formula
High-risk, start-up and recovery projects usually require more attention than stable projects of equal value. The rule is Required managers = projects × hours per project ÷ productive manager hours. Its input values are Active projects, Management hours per project per month, Productive project-manager hours per month, Current project managers, Loaded monthly manager cost, and the main result is Required project managers. Try changing one number and watch what happens to Required project managers.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Required managers = projects × hours per project ÷ productive manager hours, evaluated from Active projects, Management hours per project per month, Productive project-manager hours per month, Current project managers, Loaded monthly manager cost to produce Required project managers. High-risk, start-up and recovery projects usually require more attention than stable projects of equal value. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Estimate project-manager capacity from project complexity and available management hours.
Why the business model works
High-risk, start-up and recovery projects usually require more attention than stable projects of equal value.
Inputs and operating assumptions
This model uses Active projects, Management hours per project per month, Productive project-manager hours per month, Current project managers, Loaded monthly manager cost. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Required managers = projects × hours per project ÷ productive manager hours
What the calculator produces
The primary output is Required project managers; it also exposes Manager capacity shortfall, Monthly staffing cost at requirement. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
