Methodology for opportunities

The ISO 45001:2018 standard does not dictate any specific process or format to follow for identifying and addressing OH&S opportunities. Many companies will simply do this through a brainstorming session with top management to identify what opportunities exist and what needs to be done about them; the opportunities can then be tracked through a simple spreadsheet or any other tracking mechanism used by the company for planned activities. Other companies may use a more formal SWOT analysis (Strengths, Weaknesses, Opportunities & Threats) to identify the opportunities that are available.

No matter what process you use, it is important to make sure it is a benefit for your organization and not just a complex and confusing process that you think you need to satisfy a requirement which does not provide any advantage to you.
