The 3 SLA Mistakes That Make Your Team Look Bad

A well-designed SLA is one of the most powerful operational tools available to any business leader. A poorly designed SLA is a liability — one that demoralises your team, misleads your clients, and creates the appearance of accountability without the substance of it. In our work across banking, contact centres, and service operations, we have seen the same three mistakes appear consistently.

Mistake 1 — Measuring Activity Instead of Outcomes

The most common SLA mistake is defining metrics that measure what your team does rather than what your clients experience. Response time is an activity metric. Resolution time is an outcome metric. Teams optimised against activity metrics become very good at the activity — and completely disconnected from the outcome.

• Replace "response time" with "resolution time" where possible
• Add client satisfaction scores as a parallel metric to operational metrics
• Review every SLA metric and ask: "Is this something the client cares about, or something we care about?"

Mistake 2 — Setting Targets Without Analysing Baseline Capability

SLA targets are frequently set in commercial negotiations, not in operational reality. A sales team commits to a 24-hour resolution SLA because the client asked for it — without checking whether the operations team has ever achieved it. The result is an SLA the team misses from day one, creating a permanent state of underperformance.

This approach creates achievable initial targets that build confidence, gives the operations team a clear improvement path, and prevents the credibility damage that comes from a missed SLA in the first month of a new contract.

Mistake 3 — Making the SLA Static

Business conditions change. Team capacity changes. Client volumes change. An SLA written at contract signature that is never reviewed is almost certainly wrong within 12 months.

• Build a formal SLA review cycle into every client contract — quarterly for high-volume relationships, annually for standard ones
• Create a clear escalation mechanism for SLA breaches that distinguishes between systematic failure and exceptional circumstances
• Define exclusions explicitly: what constitutes force majeure? What volumes are outside the contracted scope?

The SLAs that serve your business best are the ones designed collaboratively, rooted in real performance data, and reviewed regularly. They become a shared language between your team and your clients — not a weapon that either side can use against the other.
