Vendor Performance Reviews

Exterior maintenance vendors are typically reviewed at renewal, under time pressure, on the basis of whether anything memorable went wrong. That method has two failure modes: gradual drift goes unnoticed because no single incident stands out, and a vendor performing well receives no signal about what to keep doing.

A structured periodic review addresses both, and it need not be elaborate. Twice a year, against measures agreed in advance, taking an hour.

What to Measure

Five dimensions cover exterior maintenance performance without becoming an administrative exercise. Weight them to your property; a Class A office and a distribution yard will not weight them the same.

The fifth is the discriminating one. Execution, reliability, and documentation are hygiene; contribution is what separates a supplier from a vendor worth keeping through a price increase.

Scoring Fairly

Three practices keep a review honest and make its output usable.

1. Score against evidence, not recollection. Punch item counts, missed windows, and documentation chases are all recorded somewhere; recollection over-weights whatever happened most recently.
2. Separate what the vendor controls from what they do not. A missed window because the lot was not cleared is a property failure recorded as a vendor one, and scoring it against them corrupts the whole exercise.
3. Score the same way each period. A review whose criteria shift is a review that measures nothing over time.

The Property's Own Contribution

A genuinely useful review examines both sides, and it is worth doing because several common vendor performance problems have property-side causes.

• Areas not cleared — the largest single cause of incomplete coverage.
• Late or vague tenant notification, producing obstacles the crew works around.
• Substrate information not provided, transferring a decision the property should have made.
• Reported conditions not acted on, which is why condition reporting stops arriving.
• Approval friction on non-routine items, which is why small problems become large ones.

Raising these alongside vendor findings changes the character of the conversation from assessment to joint problem-solving, and it tends to produce better results than the assessment alone.

Conducting the Conversation

A review conversation that opens with problems gets a defensive counterparty. One that opens with the scoring method and what scored well establishes that this is a measurement exercise rather than a complaint, which materially affects what happens next.

1. Share the criteria and weights before the meeting, not during it.
2. Open with what scored well, and be specific rather than polite.
3. Present lower scores with the evidence attached.
4. Raise the property-side findings in the same session.
5. Agree two or three specific changes rather than a general improvement expectation.
6. Set the date for the next review before closing.

Acting on the Result

The second row is the most common and the most misdiagnosed. A vendor doing exactly what the scope specifies and nothing more is performing correctly; the gap is in the specification. See vendor partnership strategies.

Frequency and Proportionality

Twice yearly suits most recurring exterior relationships — often enough to catch drift, infrequent enough to sustain. Annual is adequate for smaller scopes. Quarterly is generally too frequent to produce meaningful change between reviews.

Keep the exercise proportionate to the spend. A review process heavier than the contract it governs will be abandoned, and an abandoned review is worse than an informal one because it signals that measurement was attempted and did not matter.
