ISO Gap Analysis
A gap refers to the difference between your current state and your desired state. Gap analysis is defined as a process that involves identifying, assessing and managing the difference between your current system state and the ISO standard requirements.
It is important to initiate this process before the actual certification in order to enable the organization to prepare itself for the audit.
It is a method of evaluation that is used to measure the extent to which the actual implementation meets the planned implementation.
However, all current versions of the ISO standards do not require an organization to conduct a gap analysis. The gap analysis is an option to assess the readiness of your organization before beginning a certification audit.
A bigger gap means you have a poor implementation. You need to understand and review your implementation of the ISO management system since it is still far from the requirements.
A smaller gap means the work procedures and requirements are well executed. The smaller the gap is, the better.
