The Field-Service Capacity Constraint Diagnostic
Do you need more technicians — or a more resilient plan? Distinguish a genuine technician shortage from capacity lost to planning, readiness and schedule instability. Follow the branches; there is no score.
Start at the top Answer YES / NO Stop at your branch
START · THE OBSERVED PROBLEM
Demand is not being completed within available capacity.
DECISION 1
Over a full operating cycle, does completed work
consistently fall short of demand?
NO
OUTCOME
Not a headcount shortage
Capacity is adequate — the plan is
the constraint. Go to the fork.
YES
DECISION 2
Are overtime and unfinished work
rising together?
NO
OUTCOME
Likely a genuine shortage
Capacity converts efficiently —
hiring may be justified.
YES
DECISION 3 · THE FORK — capacity is being lost inside the operation
Where is the loss entering?
Follow the first branch that best matches the evidence.
Planned vs actual
durations diverge
CONSTRAINT
Planning accuracy
EVIDENCE TO PULL
Planned vs actual duration,
by job type and technician
FIRST ACTION
Re-baseline durations before
touching any target
HEADCOUNT
Don’t hire yet
Jobs change after
they were prepared
CONSTRAINT
Schedule instability
EVIDENCE TO PULL
Share of changes made after
prep — and who authorised them
FIRST ACTION
Set a change-freeze point;
measure the breaches
HEADCOUNT
Don’t hire yet
Parts, skills or access
missing on arrival
CONSTRAINT
Job readiness
EVIDENCE TO PULL
Repeat visits by cause;
readiness at point of release
FIRST ACTION
Hold jobs that fail a
readiness check — don’t release
HEADCOUNT
Don’t hire yet
One delay propagates
across the whole day
CONSTRAINT
No recovery capacity
EVIDENCE TO PULL
Knock-on jobs per overrun;
buffer actually left in the plan
FIRST ACTION
Protect a buffer sized to
your variability
HEADCOUNT
Don’t hire yet
Some centres overloaded,
others have space
CONSTRAINT
Network imbalance
EVIDENCE TO PULL
Completion rate and overtime
by centre and territory
FIRST ACTION
Rebalance territory and
coverage rules
HEADCOUNT
Rebalance before hiring
still not completing?
Headcount may still be justified after the fork — if the losses are fixed and demand still exceeds completed work over a full cycle.
Fix the leak first, then size the gap against a plan that actually holds.
