Gap analysis

Gap analysis commonly refers to a structured comparison between a current state and a desired or required future state, with the purpose of identifying specific shortfalls that must be addressed. In industrial and regulated manufacturing environments, it is used to understand where processes, systems, or controls do not yet meet internal standards, customer requirements, or external regulations.

What a gap analysis includes

In manufacturing and operations, a gap analysis typically:

• Defines the target state, such as a standard (for example, an internal quality specification, a customer requirement, or a regulatory/industry framework).
• Documents the current state of processes, documentation, systems, data flows, or controls.
• Compares current and target states to identify specific gaps (missing procedures, incomplete records, system limitations, training needs, etc.).
• Prioritizes gaps based on risk, compliance impact, cost, or operational criticality.
• Provides input to remediation or improvement plans, such as CAPA, continuous improvement projects, or system upgrades.

Gap analysis can be applied to many domains in industrial operations, including:

• Quality management systems and documentation control.
• Manufacturing execution and traceability capabilities (for example, comparing current MES functions to ISA-95 style requirements).
• Regulatory or standard alignment (for example, mapping current controls against NIST 800-171, CMMC, or aerospace quality requirements).
• Data integration and interoperability between MES, ERP, PLM, and other OT/IT systems.
• Workforce skills and training versus required competencies for specific operations.

How gap analysis shows up operationally

Operationally, a gap analysis may be performed as:

• A document-based assessment of policies, procedures, and records against defined requirements.
• Interviews and shop-floor observations to compare actual practices to standard work or work instructions.
• A system capability review comparing current IT/OT tools to a defined functional or compliance checklist.
• A cross-functional workshop that maps current workflows and identifies missing controls, decision points, or data.

The outputs are usually structured findings, such as a list of gaps with descriptions, associated requirements or references, and an initial severity or risk rating used to guide remediation planning.

Common confusion

Gap analysis is often mentioned alongside related terms:

• Risk assessment: Focuses on identifying and evaluating risks; a gap analysis focuses on shortfalls versus defined requirements, although gap findings may feed into a risk assessment.
• Process audit: Verifies conformity to defined procedures at a point in time; a gap analysis more broadly compares current capabilities or practices to a target or future state and may go beyond strict conformity.
• Benchmarking: Compares performance or practices to peers or industry averages; a gap analysis usually compares to explicit internal or external requirements, not just peer performance.

Use in regulated and standards-driven contexts

In regulated manufacturing, gap analysis is commonly used before formal audits, system implementations, or major process changes. Examples include:

• Comparing existing quality system elements to the clauses of a chosen quality standard.
• Assessing current cybersecurity practices against an industrial cybersecurity framework.
• Reviewing traceability and record-keeping capabilities before introducing digital travelers or a new MES deployment.

In these contexts, the gap analysis serves as a preparatory and planning tool, helping organizations understand where additional documentation, controls, training, or system changes are needed to meet defined expectations.
