Work packages are created for most scheduled work. Level of work package detail shall be based on the complexity of the work scope. Work package content shall consider clear work scope, resources (personnel, material, and/or special equipment), precautions, appropriate processes and procedures, system switching/outages, customer impact, data to be collected, signoff requirements, post-maintenance testing, and asset registry equipment update forms. Walk downs are performed by the FLS or designee. Walk downs are to ensure job estimates are accurate and barriers to prevent work execution are identified and mitigated prior to the work entering the execution schedule. Note that there are limited exceptions where walk down is not required (ex/routine corrective maintenance where job scope is understood, preventive maintenance). 3-5 years of overall work planning, scheduling and coordination required.
