Gap analysis compares what is happening now with a clearly defined result or capability you need. It helps identify the shortfall, investigate its causes, choose a response that fits, and check whether that response worked. A gap does not automatically mean people need training: the cause may instead be a process, policy, technology, leadership, communication, resource, or work-environment problem.
What gap analysis means
A gap analysis is a structured comparison between current performance and the performance required to reach a goal. The U.S. Office of Personnel Management (OPM) describes a needs assessment as identifying the gap between required and current performance. The comparison is useful only when the target is specific enough to assess: “improve service” is too vague, while “respond to customer requests within two business days” gives you something observable to compare.
In a workplace, a gap may concern results, a process, or the capabilities needed to do the work. For personal or team performance, the same logic applies: define the outcome, establish the current state, find the difference, and determine what would close it. The method is not limited to skills inventories; it asks what is required, what can currently be demonstrated, and what conditions enable or block performance.
How to conduct a gap analysis
-
Define the target
State the goal, standard, or future capability in concrete terms. Identify who or what is expected to meet it, by when, and how success would be recognized. For workforce planning, specify the skills required for current or emerging work rather than starting with a list of courses.

-
Establish the current state
Choose measures that reflect the target and collect relevant evidence. Depending on the question, useful inputs can include existing performance or workforce data, HR metrics, job descriptions, strategic plans, training records, performance appraisals, interviews, surveys, or focus groups. The CDC recommends planning the assessment and selecting appropriate ways to gather information.
Do not treat one self-rating, a single metric, or an anecdote as the whole picture when other evidence is available. Compare sources and look for patterns; self-reported confidence, for example, does not by itself establish whether someone can demonstrate a skill on the job.
-
Describe the gap
Compare the evidence about current conditions with the defined requirement. State the difference in terms that can be observed or measured, such as a result below a standard, a process step that is not being completed, or a capability staff cannot yet demonstrate. If the evidence cannot show the difference clearly, refine the target or gather better information before choosing an intervention.
-
Investigate the cause
Ask why the shortfall exists before prescribing a fix. Possible causes include knowledge or skill needs, unclear procedures, restrictive policy, inadequate technology or resources, poor communication, leadership or organizational arrangements, and work-environment barriers. The CDC’s needs-analysis guidance treats cause-finding as part of deciding whether training is necessary, not as an assumption that the problem is a training deficit.

Choose and prioritize a response
Match the response to the diagnosed cause. Training may help when people need knowledge or skills they can learn and apply; it is unlikely to resolve a broken process, missing resource, or conflicting policy on its own. Where several actions are plausible, compare their fit to the cause, likely impact, required resources, feasibility and accessibility, implementation time, and how their effects can be measured.
Prioritize gaps by their importance to the goal, consequences if left unresolved, and the resources available to act. For workforce needs, skills audits can inform development priorities, learning plans, deployment or redeployment, and budgeting. If training is considered, account for barriers such as language, technology access, and location.
-
Implement, evaluate, and adjust
Set out the action, who is responsible, the expected outcome, and the measures you will use to assess progress. Monitor relevant behavior or results after implementation and use what you learn to revise the plan. GAO’s 2026 human-capital guide treats planning, design and development, implementation, and evaluation as connected parts of a cycle; evaluation is not merely a final sign-off.
Applying gap analysis to workforce skills
For workforce planning, compare the skills needed for current or emerging work with the capabilities employees can demonstrate. Relevant inputs may include job requirements, workforce information, skills audits, training records, and stakeholder input. Keep the analysis tied to work and outcomes: an inventory can show a difference between a requirement and reported capability, but it does not by itself explain why performance is short or whether the organization provides the conditions needed to perform.

CIPD’s guide on skills matching, published 24 June 2026, discusses skills audits, development planning, and deployment of people’s skills. Skills for Care likewise connects skills gap analysis with learning plans, training records, and budgeting. For a downloadable example, the USGS Workforce Planning Desk Guide resource list includes an Occupational Gap Analysis Excel file and a Skill Gap Analysis Word document.
CIPD reports that 45% of UK employees feel their skills are under-utilised in their current roles. The guide’s search result does not identify the underlying research year, so this figure should not be read as a 2026 measurement.

- Leaving the desired state vague. Without a clear requirement, the comparison cannot guide a practical decision.
- Relying on one kind of evidence. A single data point or self-assessment may not represent actual performance; use relevant evidence from more than one source when possible.
- Blaming a skill deficit too soon. Check whether policy, process, technology, leadership, resources, communication, or the work environment is preventing the expected result.
- Buying or delivering training before identifying the cause. Training is appropriate only when it can address the diagnosed knowledge, skill, or behavior need.
- Trying to fix every gap at once. Rank findings by importance, consequences, feasibility, and available resources.
- Treating implementation as completion. Check the outcome and revise the response if the evidence shows it has not closed the gap.
Sources and scope
The method described here draws primarily on workforce and training guidance. The CDC’s Assess Training Needs: Conducting Needs Analysis (5 February 2025) covers evidence gathering, cause analysis, and deciding whether training is needed. OPM’s Planning & Evaluating discusses needs assessment, information sources, causes, and monitoring. GAO’s 2026 guide to developing and assessing federal training and development efforts describes an integrated cycle and ongoing evaluation; its earlier 2004 human-performance guide frames improvement as an approach to adapt to circumstances.
For workforce-specific planning, see CIPD’s Skills matching: Using and deploying people’s skills effectively in the workplace, Skills for Care’s Planning guidance, and the USGS Workforce Planning Desk Guide.
