MOCs are difficult to manage and most sites allow them to pile up as priorities shift in maintenance and operations. Many times, MOCs sit around collecting dust and not getting implemented. Think about if these changes are absolutely necessary. Sometimes, upon second review the MOC has hazards or benefits that were not covered initially. If you find the MOC is still valuable, schedule it for completion! However, if the MOC is found to not be as desirable as initially intended, the MOC needs to be eliminated. Keep in mind that an MOC associated with a PHA needs to be reevaluated by the PHA team, and not only the operational management team.
