A method executed in a process control environment automatically generates, displays, and tracks check lists according to assigned work items. The work items include information such as required equipment, required safety equipment, required tools, target function, and target equipment. The target function and/or target equipment information can be associated, together or separately, with the required equipment, required safety equipment, and required tools if the required equipment and tools are not specifically included in the work items. The check lists indicate the required equipment, tools, devices, parts, maintenance materials, manuals, and/or documents, that are necessary to perform the target function on the target equipment. A check list is displayed on a user interface device, which tracks, internally or in cooperation with a supervisor engine, whether a user of the user interface device has checked off the items on the check list.
