MaintWiz Shutdown Module FAQ: Questions and Answers
The MaintWiz shutdown module is an add-on to the MaintWiz platform that plans, schedules, controls and closes out plant shutdowns. The questions below cover how it schedules, checks readiness, handles spares and permits, works in the field and connects to SAP, Excel, Microsoft Project XML, Primavera P6 interoperability and IoT.
Questions about shutdown practice itself are answered in the linked guides.

Functionality
What does the shutdown module do?
The shutdown module plans, schedules, controls and closes out shutdowns, with Gantt, readiness gates, field work orders, earned value and executive views, AI agents that propose changes for a person to approve, and forecasting of delay causes, Monte Carlo confidence and critical chain analysis.
| Area | What the module does |
|---|---|
| Schedule | Gantt chart with critical path and float, a flag at a float limit you set, baselines that show what moved; forecast causes, Monte Carlo finish confidence, critical chain analysis, what-if scenarios |
| Field work | Work orders with tick, reading and photo tasks, QR code scan, offline use on transaction screens; saving readings, hours, parts, notes and attachments across a page reload |
| Control | Readiness gates configured to your requirements, with signed waivers, earned value, risk register, portfolio and executive views; risks ranked by days at stake, daily actual cost storage |
| AI | AI agents propose changes from live project numbers; a person approves each one |
Connections
Which systems does the shutdown module connect to?
The shutdown module connects to SAP through the PM or the MM module, to Excel, to Microsoft Project XML, with interoperability with Primavera P6, to ePTW for permits and isolations, and to IoT sources, with SAP kept as the system of record.
More on SAP: SAP PM shutdown management, SAP MM shutdown materials and keeping maintenance history in an S/4HANA migration. The specifications are also in a PDF data sheet.
| System | What the module does with it | Note |
|---|---|---|
| SAP (PM or MM module) | Shows each short part with its SAP status: none, purchase request raised or purchase order issued | SAP stays the system of record; one mode is used, not both |
| Excel | Imports resources and work load from templates; the tables behind charts export to Excel | Search, paging and CSV export on the tables |
| Microsoft Project XML and Primavera P6 | Schedules import from and export to both | Tool-specific mapping is set up during implementation |
| ePTW | Permits and isolations appear on each work order and in the readiness gate | A package with an open permit cannot be closed |
| IoT sources | Can feed readings into the plan | Check the data sheet for current sources |

Questions
Frequently asked questions
What is the MaintWiz shutdown module?
It is an add-on module of the MaintWiz platform that plans, schedules, controls and closes out plant shutdowns, turnarounds and outages, from the portfolio down to the task a technician ticks. See the module overview.
Who is it for?
Central planners and project managers plan and control. Foremen and technicians run the work orders. Executives use one view across projects. Administrators set calendars, rates and access by role. A foreman sees only My Day and the work orders of Execute by default.
How is it different from the maintenance features I already use?
The shutdown module reuses the platform: work orders, spares, approvals, ePTW permits, preventive maintenance scheduling, instruments and calibration, and SAP integration. It adds the time-boxed plan, the critical path, the readiness gates and the portfolio view.
What is the difference between a shutdown, a turnaround and an outage?
A shutdown is any deliberate stop; a turnaround is usually the large, planned, periodic form; an outage is any period out of service and can be planned or unplanned. See the full comparison.
How does the schedule work?
The Gantt chart shows every activity with its dates, its float and the critical path. The system flags an activity when its float falls to a limit you set, and a baseline shows what moved. 1 See shutdown scheduling.
What are readiness gates?
Seven checks for each work package before it starts: materials, resources, predecessors, tools and scaffold, permits and isolations, scope and engineering, and a go result. A person with authority can waive a gate or sign off a package, with a typed reason that is saved with the name and the date.
How are spares and SAP handled?
Each part shows quantities needed, in stock and short, the week it is needed and its SAP status: none, purchase request raised or purchase order issued. SAP stays the system of record. See the spare parts guide.
How do permits and isolations work?
They come from ePTW and appear on each work order and in the readiness gate. A work package with an open permit or isolation cannot be closed. See permit to work during a shutdown.
How do technicians work in the field?
On a phone or tablet a technician opens a work order, scans the equipment QR code, ticks tasks, enters readings against their limits and attaches photos. A reading outside its limits is marked out of spec, and a finding goes to the planner as a request for added work. Transaction screens work offline.
How is cost tracked?
The module shows planned value, earned value and actual cost against time, the cost index and the schedule index, and the budget, actual cost and forecast of each project.
What does an executive see?
A health matrix with the worst project first, decisions ranked by their effect in days and in money with Approve and Decline, and one timeline of all projects with proposed projects shown as dashed bars.
Which systems does it connect to?
SAP through the PM or the MM module, Excel, Microsoft Project XML, interoperability with Primavera P6, IoT sources and ePTW.
Can I bring in my existing plan?
Yes. Resources and work load from Excel templates, and schedules import from and export to Microsoft Project XML, and are interoperable with Primavera P6. The tables behind the charts export to Excel.
How many projects can it handle?
It handles projects running at the same time in one portfolio, shown on a board or on a timeline.
What does it not do today?
It does not track the delivery of spares, and it works offline on transaction screens.
