Gap Assessment

A gap assessment is a structured review used to compare the current state of processes, systems, controls, or documentation against defined requirements or target conditions. In industrial and regulated manufacturing environments, it commonly refers to evaluating operations against standards, regulations, internal policies, or reference models to identify where requirements are not fully met.

What a gap assessment includes

In practice, a gap assessment typically involves:

• Clarifying the reference requirements or targets, such as regulations, standards, corporate procedures, or system specifications
• Documenting the current state of processes, technologies, organizational roles, and records
• Comparing current practices and controls to each requirement or expectation
• Identifying gaps, partial compliance, and unclear or conflicting practices
• Summarizing findings in a structured way, often with risk, impact, and priority indicators

In manufacturing, gap assessments are often applied to areas such as:

• Manufacturing execution systems (MES) capabilities versus ISA-95 style functional models
• Quality management processes versus internal quality system procedures
• Data integrity and electronic records practices versus regulatory expectations
• Cybersecurity controls in OT environments versus a chosen security framework
• Document control and change control practices versus policy requirements

Operational meaning in manufacturing environments

Operationally, a gap assessment provides a structured list of where current operations or systems do not align with required or desired practices. The output is usually:

• A set of documented gaps, each linked to a specific requirement or expectation
• Evidence or observations that support each identified gap
• High-level recommendations or considerations for remediation, often used as input to a remediation plan or roadmap

Gap assessments are descriptive rather than prescriptive. They describe where misalignments exist but do not, by themselves, implement changes or guarantee any specific compliance or certification outcome.

What a gap assessment is not

A gap assessment is not the same as:

• An implementation project or remediation program. It precedes and informs those activities.
• A full formal audit in the regulatory or certification sense, although the methods and documentation can be similar.
• A root cause analysis. It may highlight where requirements are not met without determining the underlying causes.

Common confusion

Gap assessment vs. gap analysis: In many organizations the terms are used interchangeably to describe the comparison of current state to a target. Some practitioners use “assessment” to emphasize a structured, documented review and “analysis” for the deeper examination of causes and options, but this distinction is not universal.

Gap assessment vs. risk assessment: A gap assessment focuses on alignment to defined requirements or targets. A risk assessment focuses on identifying and evaluating risks, which may include but are not limited to compliance gaps. Gap assessment results often feed into risk assessment activities.

Use in regulated and integrated manufacturing systems

In regulated manufacturing and integrated OT/IT environments, gap assessments frequently address:

• MES and ERP integration practices versus defined data integrity, traceability, or interoperability requirements
• Quality system processes (for example, CAPA, change control, batch record management) versus internal or external expectations
• Audit readiness, especially identifying missing or incomplete evidence needed to demonstrate adherence to procedures
• Cybersecurity controls on shop floor assets relative to a chosen security baseline for industrial control systems

The output of these assessments is often used to prioritize system enhancements, process redesign, documentation updates, training, and governance changes.
