How clients and suppliers handle deviations without losing momentum

Deviations occur in every digital assignment. What determines whether an assignment succeeds is not the absence of deviations but how they are handled. A clear, swift, and documented deviation management process reduces the risk of small issues becoming large problems and creating unnecessary friction between client and supplier.

What is a deviation?

A deviation in a digital assignment is when something differs from what is contracted, planned, or expected. Examples include:

• A deliverable that does not meet its acceptance criteria.
• A planned delivery that is delayed.
• A change in requirements that affects scope or timeline.
• An incident in the production environment.
• A technical deficiency or security issue identified during operation.

The boundary matters: not every question or uncertainty is a deviation. Ongoing dialogue, queries, and discussions are handled through the normal communication channel. A deviation is something requiring a formal response and documentation.

Reporting channel and ownership

From day one it should be clear: where are deviations reported, and who receives them? There should be a dedicated channel – not a mixed email thread – and a named person at the supplier who owns the deviation from report through closure.

Severity and prioritisation

Not all deviations are equally serious. A simple classification helps prioritise correctly:

• Critical: production environment is down or unavailable to end users. Requires immediate action.
• High: significant functionality is affected but the system is not down. Requires prompt action.
• Medium: non-critical function affected. Handled in the next cycle.
• Low: cosmetic issue or improvement suggestion. Handled after prioritisation.

Immediate actions

For serious deviations there should be a defined first step: what is the immediate action to limit damage? This may mean rolling back a deployment, temporarily disabling a function, or escalating to the next responsibility level.

The immediate action does not need to resolve the issue – it should stabilise the situation while investigation and permanent remediation are planned.

Root cause and decisions

After the immediate action, a lightweight root cause analysis should be performed. No advanced framework is required – the question to answer is: what caused the deviation, and what needs to change to prevent recurrence?

The root cause is documented in the deviation log along with the remediation decision and who made it.

Traceability and follow-up

A deviation is not handled until confirmed closed by the right person. The deviation log should record:

• Report date and who reported.
• Classification.
• Immediate actions taken.
• Root cause.
• Decision on permanent remediation.
• Closure date and who confirmed closure.

Lessons learned

Recurring deviations in the same category indicate a systemic issue. A regular review of the deviation log – once per sprint, month, or phase – provides the opportunity to identify patterns and address root causes before they escalate.
