What are task lists in a maintenance process used for?

According to the SAP S/4HANA Cloud, public edition Learning Journey1, task lists in a maintenance process are used for performing a sequence of work steps and planning spare parts for repetitive maintenance. Task lists are documents that contain the information and activities required for performing maintenance work on an asset or equipment. Task lists can be used to standardize and optimize the maintenance process by defining the work steps, resources, materials, and durations for each maintenance task. Task lists can also be used to plan spare parts for repetitive maintenance by specifying the materials and quantities needed for each maintenance task.
