The working group quickly agreed that it was line managers’ responsibility to implement the critical controls, but there was still disagreement about the verification activities. Some members said that HSE already did audits, and the verification was just another type of audit, so they should be responsible for the verification of critical controls as well. The opposite view was put by the senior manager and project sponsor who was present. The project sponsor argued that an essential part of any line manager’s job was to check (or verify) that tasks within their sphere of responsibility were being done as intended.

The line of accountability is also outlined in Table 3, from the verification owners to the leadership team and board of a company. Each tier within the line of accountability includes additional governance responsibilities for CCM than the tier below it. This provides a robust governance structure that includes all levels of ownership. The high-level reporting requirements are also outlined in Table 3. The products of each report, and the frequency of each review period, are outlined as part of each tier’s responsibilities.
