How to Improve an Underperforming Process

Improve an underperforming process by validating the problem, investigating evidence, choosing controlled changes and checking overall results.

Improving an underperforming process begins with a clear statement of the intended result and the evidence that actual performance falls short. The organisation should understand the problem before selecting a solution. More training, automation or a redesigned map may help in particular cases, but none is a universal response.

The process management guide explains the surrounding system. The approach below connects diagnosis, controlled change and later evaluation while recognising effects on recipients and supporting processes.

Confirm the gap and the basis for judgement

Identify the required or authorised outcome, the current result and relevant conditions. A statement such as the process is inefficient may conceal several different problems: unsuitable output, unnecessary resource use, delay or an unrealistic target.

Check the measure definition and data quality. A changed denominator or reporting point can create an apparent deterioration without a comparable change in actual work.

The performance indicators article explains these definitions. Do not redesign a process solely because a dashboard changed colour without understanding what the result represents.

Address immediate consequences where needed

Some performance concerns require prompt control of affected work while investigation continues. Unsuitable output, an uncontrolled release route or a missing critical input may justify a proportionate interim response.

Identify responsibility and authority for that decision. Improving the long-term process is different from controlling the immediate issue, although the activities can inform one another.

Avoid using a temporary workaround indefinitely without review. Define its purpose, limits and relationship to the eventual decision where relevant.

Follow evidence through actual work

Trace ordinary cases and relevant exceptions from input to output. Examine decisions, handovers, resources, waiting and rework. Include the people who perform the work and those who receive its results.

A process map can organise the investigation, but it does not prove the cause. Compare records, observations and explanations. A plausible account such as people are not careful enough needs evidence and further examination of the conditions that allowed the gap.

Look for variation that helps explain the problem. A service type, shift, supplier or exception route may perform differently. Avoid averaging away a consequential smaller category.

Evaluate causes and constraints

Ask how the process produces the observed result. Missing information, unclear authority, unavailable resources, unsuitable criteria or conflicting targets can each suggest different action.

Distinguish a symptom from an explanation. More waiting at approval may arise because the approver receives incomplete input, not because the approval step itself is unnecessary.

These are investigation prompts, not predetermined diagnoses.

Select changes with a reasoned connection

Explain how the proposed action addresses the supported cause or constraint. Consider alternatives and relevant effects on connected work. Removing a check may shorten the route while allowing unsuitable output to pass.

Identify resources, competence, documentation and system changes needed. Assign an owner with a practical route to coordinate affected functions.

Where appropriate, test the change on a suitable scale and define acceptance conditions. Include cases that exercise the original weakness rather than only straightforward work.

Evaluate the result, including side effects

Define what later evidence would demonstrate benefit and when relevant work will occur. Completion of an action or installation of software does not establish a better process result.

The effectiveness evaluation article explains the relationship between intended outcomes and evidence. Compare compatible periods or cases and acknowledge limits such as small populations or simultaneous changes.

Check the receiving process and other important constraints. A local improvement can increase downstream rework, reduce necessary information or create a new bottleneck. Evaluate the overall result rather than only the sponsoring team’s target.

Standardise what works and continue learning

If the change is suitable, update relevant arrangements through controlled review and communication. Preserve necessary history and confirm that people can operate the new method.

If the result is weak or uncertain, reconsider the evidence and assumptions. Do not repeatedly add actions merely to defend the original solution. Further enquiry or a different approach may be justified.

Review whether the improvement remains effective as workload and conditions change. A process can perform well during a supported trial and deteriorate when normal variation returns.

Useful improvement connects a verified problem with evidence-based decisions and demonstrated results. It preserves immediate responsibility for affected work while changing the mechanisms that influence performance, with enough coordination to improve the system rather than move its difficulties elsewhere.
