Detailed Maintenance Scheduling

Reviewing maintenance requests
- Does a systematic order management exist?
- Who creates the maintenance orders and in which system are they maintained?
- What information in which level of detail must the maintenance request contain (allocation of resources, error description, problem/cause analysis)?
- Who controls this information?
- Are maintenance requests budgeted, are orders necessary?
- How are the maintenance staff informed about new orders?
- Do several trades have to be planned/coordinated to process the maintenance request?

Confirmation or rejection of maintenance requests
- Who confirms or rejects a maintenance request?
- What conditions result in the confirmation or rejection of the maintenance request?
- Can orders be rejected (for what reasons)?
- How does the requester receive feedback on the status of the maintenance request?

Determining the priority of the request and the level of effort and availability of all resources
- How is detailed planning done, how is the sequence of work planned and who is responsible for it?
- Can priorities be changed subsequently?
- Which information from other systems must be used to be able to make decisions?
- Are there dependencies between the trades involved?
- Who provides the resources for the orders?
- What is the intended target utilization(capacity planning)?

Scheduling the maintenance request to be performed within a detailed maintenance schedule
- How are planned and unplanned measures distinguished?
- What capacities are reserved for unplanned operations?
- Are detailed schedules available or specified for all measures?
- Are there interfaces between the inspections?
- Should the plan specifications be used to map KPIs?

Coordinating planned work with operators and plant supervision
- How are the work permits issued on site in the plants?
- What responsibilities and roles are there at the interface with the plants?
- Do special roles need to be defined depending on the scope/criticality of the work (e.g. safety coordinator, security guard, fire watch)?
- Are priorities agreed jointly?
- Is there a joint scheduling of maintenance activities?
- Do parts of the plant have to be taken out of operation?
- Do resources have to be provided by the plant?
- Are there maintenance activities that are performed by production staff?
