Shutdown software
Pharmaceutical Shutdown Software with Gates and Approvals
Pharmaceutical shutdown software plans a planned maintenance shutdown that ends in requalification and return to use. In MaintWiz, utilities, HVAC, filter and calibration work run as packages, a readiness gate is set to your requalification checkpoint, every approval and waiver is recorded against the signed-in user with name, time and a typed reason, and the history of schedule changes is kept. MaintWiz supports FDA 21 CFR Part 11 process compliance.
How MaintWiz helps: MaintWiz is a comprehensive shutdown solution for pharmaceutical plants. It holds the shutdown behind release gates you configure, with every approval recorded by name and time.
- Scope, plan, schedule, execution and close-out in one module
- Critical-path Gantt with float and baselines
- Release gates you configure, signed off by name
- Integrated ePTW: permits and LOTO isolations on every work order
- Earned value: planned, earned and actual, with cost and schedule indices
- Spares needed, in stock and short, with SAP status

The shutdown
What makes a pharmaceutical shutdown hard to release on time?
The work is ordinary maintenance; the release is not.
Change-controlled sequence
Work runs in the order change control allows, not just the fastest order.
Requalification as a gate
Return to use waits for requalification and quality approval.
Evidence for audits
Every approval and change must be recorded with who and when.
Utilities with no slack
HVAC and water systems leave little room to re-sequence.
EU GMP Annex 1 sets a maximum requalification interval of 6 months for grade A and B areas and 12 months for grade C and D areas, with extra requalification after changes. 1 Annex 15 asks for quality risk management to evaluate planned changes and plan requalification 2, and 21 CFR 211.67 requires written procedures for cleaning and maintenance of equipment. 3
MaintWiz
How does MaintWiz run a pharmaceutical shutdown?
The engineering and quality leads' problems, each with its screen.
| Your problem | What MaintWiz does |
|---|---|
| Requalification as a gate | Configurable readiness gates, with one set to your requalification checkpoint |
| Evidence | Approvals recorded against the signed-in user with name and time, waivers with a typed reason, and the history of schedule changes |
| Regulated records | MaintWiz supports ISO, FDA 21 CFR Part 11 and OSHA process compliance |
| Instruments and calibration | Instruments and calibration on the platform, tied to the job |
| Utilities with no slack | Gantt with critical path and float for HVAC and water-system packages |
Records
How does MaintWiz keep shutdown records for audits?
Who did what, who approved it, and when, kept with the work.
Approvals
Each approval is recorded against the signed-in user with name and time.
Waivers
A waived gate needs a typed reason, a name and a date.
Change history
Every schedule change is kept, with who made it and what changed.
Close-out
Handover, lessons and deferred items are archived with the shutdown.
Measures
What should you measure in a shutdown?
A few measures tell you whether the shutdown went well; MaintWiz reads them from the same plan the field updates.
Requalification first time
Requalification passed without a repeat.
Days from last repair to release
Time from the last job closed to quality approval.
Deviations raised
Deviations raised during the shutdown work.
Shutdown days against plan
Release date against the plan.
Batches released on time
The first batches after restart released as planned.
Worked example
Worked example: a two-week shutdown to release
ILLUSTRATION: an oral solid dose plant: HVAC filter changes, a water-loop passivation and 120 instrument calibrations, then requalification.

One system
Why run the shutdown inside the CMMS?
The shutdown uses the same equipment, spares and permits as everyday maintenance; keeping them in one system removes the re-keying between tools.
Work orders and history
Every shutdown job is a work order on the same equipment record, so findings and repairs stay in the asset's history.
Spares and SAP
Needed, in stock and short come from the same stores data, with the SAP request or order behind each short part.
Permits and isolations
ePTW permits and isolations sit on each work order, and a package cannot close while one is open.
AI agents with an approver
AI agents review scope, estimates and the schedule and write daily summaries; each proposal has a named person who approves it.
Who uses it
Who uses MaintWiz in a shutdown?
Each role sees its own part of one plan, so nobody works from a copy.
| Role | What they see | What they decide or record |
|---|---|---|
| Site head | Release date and cost | Decisions on scope and timing |
| Engineering manager | Packages, utilities windows and gates | Sequence and recovery |
| Planner | Critical path, float and calibrations | The plan and its baseline |
| Quality | The requalification gate and approvals | Return to use |
| Technicians and contractors | Their jobs on the mobile app | Progress, readings and photos |
Getting started
How do you start before the next planned shutdown?
Start from last year's shutdown list and your release steps.
- 1
Load last stop's job list
Import last shutdown's job list from Excel, or the schedule as Microsoft Project XML; MaintWiz is interoperable with Primavera P6.
- 2
Fix the release date
Set the date that cannot move and let the critical path, float and baselines show what drives it.
- 3
Set the gates
Configure the seven readiness gates to your rules: materials, resources, predecessors, tools and scaffold, permits and isolations, scope and engineering, and go.
- 4
Bring the crews in
Planners, supervisors, technicians and contractors get role menus and the native mobile app, with offline work on transaction screens.
- 5
Close and keep it
Close-out records handover, lessons and deferred items, so the next stop is planned against this one.
MaintWiz is shutdown management software built into an AI CMMS, so the stop shares work orders, spares, ePTW permits and maintenance history with the rest of the plant. For the sector background, read pharmaceutical plant shutdown requalification.
FAQ
Frequently asked questions
What does pharmaceutical shutdown software do?
It plans and runs a planned maintenance shutdown through to return to use: utilities and HVAC work, calibrations, a requalification gate and approvals recorded with name and time.
Can MaintWiz hold a requalification gate before return to use?
Yes. Readiness gates are configurable, so one gate is set to your requalification checkpoint and must be signed before the plan moves to release.
How are approvals recorded?
Each approval is recorded against the signed-in user with name and time, and a waiver needs a typed reason, a name and a date.
How does MaintWiz support audit evidence for shutdown maintenance?
Approvals, waivers and the history of schedule changes are kept with the work, and close-out archives the shutdown with its handover and lessons.
Can instrument calibration be planned in the shutdown?
Yes. Instruments and calibration run on the MaintWiz platform, tied to the job in the shutdown plan.
Does MaintWiz support 21 CFR Part 11?
MaintWiz supports ISO, FDA 21 CFR Part 11 and OSHA process compliance in the way approvals and records are kept.
How are HVAC and water-system outages sequenced?
As packages on the Gantt with their critical path and float, so their windows are held and the work around them is scheduled in sequence.
Can we start from last year's shutdown plan in Excel?
Yes. Import the job list from Excel or the schedule as Microsoft Project XML, then configure the gates, including the requalification gate.
How is MaintWiz priced?
MaintWiz is a subscription that grows with your users, sites and modules, with a fixed implementation fee; ask for a written quote at a demo.
Can MaintWiz use the equipment records we already have?
Yes. Equipment lists and job lists load from Excel, schedules from Microsoft Project XML, and where the plant runs SAP, assets and their codes sync from SAP PM or MM.
