Subcontractor Performance Score
Score subcontractor performance across quality, schedule, safety and cost using a weighted 1–5 model.
Score = 20 × (0.30·Quality + 0.30·Schedule + 0.25·Safety + 0.15·Cost)Interpretation Guide
- 80 – 100Preferred.
- 60 – 79Acceptable.
- < 60Poor.
Example
Q4, Sch4, Saf5, Cost3 → Score ≈ 82 (preferred).
Real-world use cases
- Subcontractor prequalification
- Award decisions
- Performance reviews
Common mistakes
- Letting cost dominate the score on safety-critical work
Professional tips
- Capture evidence (NCRs, RFIs, LTI) per dimension
Frequently asked questions
Can I change the weights?
Yes — adjust to reflect contract risk profile (safety-critical, fast-track, etc.).
What this tool does
Score subcontractor performance across quality, schedule, safety and cost using a weighted 1–5 model.
It applies the standard formula Score = 20 × (0.30·Quality + 0.30·Schedule + 0.25·Safety + 0.15·Cost) so planners, schedulers and PMOs get a defensible number they can put in front of a steering committee.
Looking for the underlying terminology? Open the PM Glossary or the PM Cheat Sheet for quick references on EVM, scheduling and risk terms.
When to use it
- Subcontractor prequalification
- Award decisions
- Performance reviews
Typical owners: project managers, planning engineers, project controls leads and PMO analysts running weekly or monthly performance reviews on EPC, infrastructure, IT and construction projects.
How to interpret the result
Treat the number as a signal, not a verdict. Read it together with the trend over the last 3–6 reporting periods, the critical-path status, and the risk register before you change the plan.
- Compare against the baseline, not against another project.
- Investigate the drivers behind the value before reporting it up.
- Pair it with at least one complementary KPI (cost, schedule, risk or quality).
Worked example
Q4, Sch4, Saf5, Cost3 → Score ≈ 82 (preferred).
In a real project review, document the inputs, the resulting value, the interpretation, and the corrective action you committed to. That audit trail is what turns a calculator output into a controls decision.
