Task List
How does a Task List differ from a Work Order in ServiceGrid/CMMS?
A Task List is a reusable definition of maintenance activities (scope, criteria, resources), while a Work Order is a scheduled instance of execution tied to an asset, date, and technician, referencing the Task List for activity details.
What RCM logic governs Task List creation?
JA1011 task-selection logic uses the P-F interval, consequence category, and cost-benefit test to choose PM, CBT, or run-to-failure tactics per failure mode.
How are Task List results used for reliability analytics?
Each step’s acceptance criterion yields binary/quantitative data (e.g., vibration ≤2 mm/s) that feeds CMMS work history, enabling MTBF/MTTR calculation, failure mode linking, and PM optimization.
Can a Task List include condition-based triggers?
Yes; it can embed measurement points and condition checks (e.g., temperature, vibration) that, when exceeding thresholds, auto-generate follow-up work orders via CMMS integration with condition-monitoring tools.
How is ISO 14224 data captured via Task Lists?
SAP PM Task Lists structure inspection, lubrication, measurement, and replacement steps to ensure standardized execution and reliable failure data collection for asset integrity per ISO 14224.
A Task List in a CMMS (e.g., ServiceGrid) is a standardized, reusable library of maintenance activities—such as inspection steps, lubrication, measurements, and parts replacements—that defines what must be done, how, and with what resources, but is not tied to a specific work order date until assigned. It serves as the execution standard for Preventive Maintenance (PM) programs, created via RCM/FMEA and assigned to assets to generate time- or condition-based work orders.
On the shop floor, technicians execute Task Lists via digital checklists on mobile devices, with each step having an actionable acceptance criterion. This produces auditable results that feed CMMS work history and reliability analytics like MTBF and MTTR. Practical application involves writing asset function statements, identifying functional failures and failure modes, estimating P-F intervals, applying RCM task-selection logic (JA1011), and documenting each task with scope, criteria, frequency, labor role, and parts/tools. After sign-off by a facilitator, reliability engineer, asset owner, and operations manager, the Task List is loaded into the CMMS with a worksheet reference for traceability. Tasks are grouped into practical packages for PM execution, assigned to specific equipment, and work orders reference the Task List to define activities. Multiple items can exist under one plan for assets in the same functional location.
Generic, non-failure-mode-linked Task Lists derived from OEM manuals without RCM analysis, leading to over-maintenance or missed critical checks, increasing cost and downtime.
Missing acceptance criteria or actionability in checklists with vague steps (e.g., 'inspect bearing') and no measurable criteria, producing inconsistent, non-auditable results that corrupt CMMS history and mask reliability trends.
Task lists not updated after PM optimization, retaining obsolete tasks post-RCM/PM optimization, causing wasted labor, unnecessary parts consumption, and delayed detection of emerging failure modes.
