Project Resource and Capacity Guide

Plan net availability, skills, workload, utilization, labor cost, leveling, and sustainable team capacity.

Core concepts

Build the mental model first

Gross availability: Calendar working time before leave, operations, meetings, and other deductions.
Net capacity: Realistic productive time available to project work.
Utilization: Assigned or productive time relative to available capacity under a defined method.
Resource leveling: Adjusting dates or sequence to resolve over-allocation, potentially changing the critical path.

Formula reference

Measure	Formula	Interpretation
Utilization	Assigned hours ÷ available hours × 100	Requires a consistent availability definition.
FTE demand	Required hours ÷ available hours per FTE	Planning demand expressed as full-time equivalents.
Loaded cost	Labor + overhead + non-labor cost	Total cost boundary used for decisions.

Worked reasoning

A critical specialist is planned at 145% capacity for six weeks.

Validate net availability and skill substitution, then compare sequencing, leveling within float, scope changes, or temporary capacity.

Sustained overload is not a capacity plan; it converts a visible resource constraint into schedule, quality, and retention risk.

PMP lens

Resource smoothing stays within float where possible.
Resource leveling may change the finish date.
Acquire resources considers both internal and external options.
Teams need psychological safety and clear working agreements, not only assignments.

Common doubts

Is 100% utilization desirable?

Usually not for knowledge work; high utilization creates queues, interruptions, and reduced ability to absorb uncertainty.

Are FTE and headcount the same?

No. FTE is capacity equivalent; headcount is the number of people.

Should meetings be excluded from capacity?

Include required coordination in the capacity model rather than pretending every paid hour is productive delivery time.
