Principle 07

A Good Relationship Is Not a Performance Measure

· · 7 min read
In short

Relationship signals - responsiveness, effort, access, senior familiarity - describe how a supplier relationship functions, not whether the purchased outcome is being delivered. When performance is not defined in advance, anecdotes fill the gap, strong suppliers go undervalued and weak outcomes get tolerated. Keep four links visible for every important supplier: promise, measure, response and decision. Trust the relationship; measure the outcome.

Good supplier relationships are valuable.

They make difficult conversations easier, accelerate problem solving and create room for candour. A supplier that understands the organization can often respond faster than one still learning its systems, stakeholders and risks. None of that should be dismissed.

But a good relationship can become a poor substitute for a clear view of performance. Meetings feel constructive. The account team is responsive. Senior leaders know one another. Problems are handled with reassuring language. Yet the organization may still be unable to answer a basic question: are we receiving the outcome we are paying for?

Relationship quality influences how people work together. Performance evidence shows whether the work is producing value. Mature commercial leadership needs both.

Why do smart leaders confuse relationship with performance?

The confusion is understandable. Supplier outcomes are often difficult to observe in one clean number. Service quality may depend on internal teams, changing demand or risks neither side fully controls. Meanwhile, relationship signals are immediate: responsiveness, effort, access and confidence in the people involved.

Those signals matter, but they answer a different question. They tell you how the relationship feels and functions. They do not, by themselves, prove that the required outcome is being delivered at the expected level, cost or risk. It is the same asymmetry that makes familiarity expensive in Principle #6.

What is the danger of performance by anecdote?

When performance is not defined in advance, anecdotes fill the gap. One stakeholder remembers a successful escalation. Another remembers an outage. The supplier highlights activity: meetings held, tickets closed, reports produced and hours invested. Everyone brings evidence, but little of it answers the same question.

This creates two commercial risks. Strong suppliers may be undervalued because their contribution is invisible. Weak outcomes may be tolerated because effort and goodwill remain visible. In both cases, the organization loses commercial confidence.

The solution is not a larger scorecard. It is a shorter chain between what was promised and what leaders need to decide.

What is the supplier credibility chain?

A supplier becomes commercially credible when four links remain visible: promise, measure, response and decision.

Figure 1. Supplier credibility grows when promises become measurable outcomes, supported by an agreed response and a decision.

1. Promise: what outcome has the supplier committed to?

Begin with the result, not the reporting mechanism. A useful promise identifies the outcome, the scope it covers and the conditions that materially affect delivery. It avoids vague language such as world-class service, continuous improvement or strategic partnership unless those ideas are translated into observable commitments. If neither side can state the promise plainly, no scorecard can rescue it.

2. Measure: what evidence will show that it happened?

Choose the smallest set of measures that reveal the outcome and help someone make a decision. Balance lagging evidence - what happened - with leading evidence that warns performance may be moving off course. Use data both parties can explain, and make the owner and cadence clear. Measurement should reduce ambiguity. It should not create a reporting industry around the relationship.

3. Response: what happens when the outcome moves off course?

A metric without a response is decoration. Agree what variance deserves explanation, who owns recovery, how quickly a plan is required and when repeated failure changes the commercial conversation. The response should be proportionate: not every miss requires escalation, but recurring misses should not be reset to zero at each review.

A scorecard becomes governance only when the evidence changes behaviour.

4. Decision: what does the evidence require us to do?

Every review should end with a decision, even if the decision is to preserve the current course. Depending on the pattern, leaders may recognize strong performance, repair an operating issue, correct scope, challenge price, adjust risk protections, or take one of the four decisions set out in Principle #4 - including a governed choice to do nothing with a review trigger. The evidence earns its place by improving the decision, not by filling a dashboard.

What should you actually measure?

The right measures depend on the outcome, but most supplier reviews benefit from a balanced view of five dimensions:

  • Outcome: did the supplier deliver the business result the organization purchased?
  • Service: was delivery reliable, timely and responsive where responsiveness matters?
  • Commercial position: do price, scope and terms remain defensible against current evidence?
  • Risk: are material operational, security, compliance and continuity obligations controlled?
  • Improvement: are agreed corrections and valuable innovations becoming real changes rather than recurring promises?

Not every supplier needs all five dimensions or the same review cadence. Governance should be proportionate to value, dependency, uncertainty and risk - the between-negotiations discipline of Principle #1.

Where does tactical empathy fit?

Performance conversations often become defensive because a metric can feel like a verdict on effort, competence or trust. Tactical empathy allows leaders to acknowledge that reality without blurring the evidence.

Label the conditions the supplier believes affected performance. Ask what they see that the data misses, what constraint is preventing recovery and what commitment they can credibly make. Do the same internally: understand whether stakeholders are protecting continuity, avoiding conflict or reacting to one memorable event. Teams can rehearse these conversations in a workshop.

Empathy improves the conversation. It does not alter the agreed outcome after the fact.

Where does LEAP fit?

LEAP - the Lowest Easily Attainable Price - cannot be separated from the required outcome. A lower price for weaker performance, hidden scope or unmanaged risk is not the same commercial position. Performance evidence helps define what is actually being purchased and whether a price comparison is like-for-like. Principle #3 sets out how that target is built.

It also reveals when the supplier's outcome remains strong but the commercial position has drifted. That distinction allows leaders to protect a valuable relationship while still correcting price, scope or terms.

A familiar executive moment

Imagine an important service provider whose quarterly reviews are consistently positive. The presentation is polished, senior attendance is strong and open issues are discussed. Yet the measures focus mainly on activity: meetings, tickets and projects underway. Business outcomes are described narratively, and recurring problems return each quarter under new action-plan language.

The answer is not to abandon the relationship or demand dozens of new metrics. It is to restate the few outcomes that matter, connect each to credible evidence, agree what happens when the evidence weakens and make the resulting decision visible.

The relationship may improve because the conversation becomes clearer. If it does not, the organization will at least know what the evidence requires next.

Principle #7 turns the scrutiny introduced in Principle #6 into an operating discipline: define the outcome, observe the evidence and let the evidence improve the next commercial decision.

Never accept a relationship signal as a substitute for an outcome measure.

Executive takeaway

  • Strong relationships create value, but they do not independently prove performance.
  • Connect every important supplier promise to evidence, an agreed response and a decision.
  • Use a small set of outcome-oriented measures rather than a large activity dashboard.
  • Make governance proportionate to value, dependency, uncertainty and risk.
  • Use empathy to improve the conversation and evidence to protect the decision.

Three questions to ask yourself

  1. 01For our most important suppliers, can we state the outcome we are paying for in one sentence?
  2. 02Which measures would warn us early that the outcome is moving off course?
  3. 03What decision would repeated underperformance actually trigger - and who owns it?
