Most CMMS rollouts at power plants take 6 to 12 months, and 60% of them stall before adoption ever happens. Going live in 75 days, with 88% PM compliance just 15 days after that, sounds like marketing language until you see the actual deployment plan that gets there. The 280 MW plant in this case study did it by following one operating rule, ruthless sequencing over scope. Asset register first, mobile rollout second, PM schedules third, and dashboards last, with hard go/no-go gates between each phase that the maintenance director refused to soften. The result was a fully digital maintenance operation by Day 75 and 88% PM compliance by Day 90. To map your own plant against this rollout, start a free trial with the OxMaint onboarding team.

The plant before Day 1
A typical CMMS-shopping plant looks like this
The 280 MW combined-cycle plant in this case had run on a fragmented mix of legacy CMMS, departmental spreadsheets, and paper work packs for nine years. The reliability manager had budget approval for a replacement CMMS but a healthy fear of joining the 60% of plants where a rollout stalls. The starting state was painfully familiar to anyone who has scoped a deployment, and the decision to choose OxMaint was driven less by features and more by the structured 75-day rollout commitment.

The 75-day spine
Four phases, hard gates, no exceptions
The entire 75 days was structured as four sequential phases, each with a defined output and a hard go/no-go gate. The most important thing the maintenance director did was protect the sequence. When operations requested early dashboards in Phase 2, the answer was no. When IT pushed for ERP integration in Phase 3, the answer was no. The phases below show the deliberate pacing that separates a 75-day rollout from a 12-month one.
Phase 1, Asset register and data foundation
Connectivity survey of every asset location. Asset hierarchy rebuilt by system, gas turbine train, HRSG, steam turbine, balance of plant. 4,100 assets validated against nameplate data, 340 records written off as unrecoverable.
Gate, register complete and validated, no PM schedule work until cleared
Phase 2, Mobile rollout and technician onboarding
Tablets provisioned, QR tags applied at every asset access point. Two-hour hands-on training session per technician across all three shifts. Five practice work orders required from each technician before production go-live cleared.
Gate, 100% technician mobile completion rate on practice WOs
Phase 3, PM schedules and parallel operation
Calendar-based PMs imported, frequencies validated against OEM manuals, criticality classes assigned to each asset. Paper work packs and mobile workflow ran in parallel for two weeks to catch every scheduling gap before paper retirement.
Gate, 14 days of parallel running with zero scheduling gaps
Phase 4, Dashboard rollout and paper retirement
Real-time PM compliance dashboard rolled out to shift supervisors and plant manager. Paper work packs formally retired on Day 71. Weekly leadership stand-up cadence locked in. Day 75 closed with a full operational review.
Gate, paper completely retired, dashboards live, full digital records

Compliance trajectory
How PM compliance climbed from 52% to 88% in 90 days
The compliance curve does not move during the first phase. That is by design. Trying to push PM completion metrics before the asset register is clean is the single most common reason rollouts collapse. Real movement began at Day 21 once the foundation was sound, accelerated through the mobile rollout, and stabilized between Day 75 and Day 90 as paper retirement closed the last execution gaps.

The team behind it
Who owned what, and why role clarity beat headcount
The rollout team was deliberately small. Six people inside the plant, three from OxMaint onboarding, no consultants. Most CMMS deployments fail when accountability gets diffused across a 20-person steering committee where nobody can make a decision. This plant did the opposite, named one accountable owner per workstream, gave each owner veto authority on scope in their area, and ran a 30-minute daily stand-up for the full 75 days.
Owner
Maintenance director
Overall program owner, sequence enforcement, executive escalation, weekly review with plant manager.
Lead
Reliability engineer
PM library configuration, criticality classification, asset hierarchy design, OEM frequency validation.

Champ
Shift B floor champion
Same as Shift A, ensures parity of training quality and rollout adoption across all three shifts.
What got migrated, what got left
The migration scope decision that kept the rollout fast
The single biggest decision in any CMMS rollout is what historical data to migrate and what to leave behind in read-only legacy access. Trying to migrate every record from nine years of mixed systems is how rollouts stretch from 75 days to 18 months. The plant followed a strict rule, migrate only what active operations require, archive the rest in read-only for 60 days post go-live, then sunset.

The six rollout killers we avoided
Why most plants take 12 months to do what this one did in 75 days
The CMMS market has a 60% Year-1 failure rate for a reason, and it is not the technology. Every failure trace back to the same six process patterns. The maintenance director on this project studied four prior CMMS implementations across the parent utility before designing this rollout, and structurally prevented each of these failure modes from happening.
K1
Building PM schedules before the asset register is clean
Creates orphaned tasks and zero adoption. This plant did not touch PM schedules until Day 22, after the register was validated and signed off.
K2
Migrating every historical record into the new system
Overwhelms users and degrades performance. Migrating only active operational data kept the new system fast and trusted from Day 1.
K3
Training technicians during live production pressure
Technicians who first encounter a system under pressure reject it. Training was complete before Day 65, never during production cutover.
K4
Keeping paper work orders as a parallel backup
Gives technicians a reason not to adopt the new system. Paper was formally retired on Day 71 with no fallback option.
K5
Skipping pilot phase and rolling out to everyone at once
Every problem becomes a plant-wide problem. Two senior technicians piloted the workflow for two weeks before broader rollout began.
K6
Customizing the platform before the basics work
Scope creep is the silent killer of 90-day rollouts. All customization requests were deferred to a post-Day-90 backlog, no exceptions.
Day 90 review
The numbers presented to the plant manager at the close-out review
A Day 90 review session anchored the entire program. Every workstream owner presented the four KPIs they had baselined on Day 1 and the current state at Day 90. No vanity metrics, no projections, no aspirational claims. The numbers below were on the screen during the actual review. Operational metrics, mobile adoption, and audit readiness all hit or exceeded the targets set in the original rollout scope.

Common questions
Frequently asked questions from plants planning a similar rollout
Is a 75-day go-live realistic for a 200-500 MW power plant with 4,000 plus assets?
Yes, when the plant has executive sponsorship, named workstream owners, and the discipline to defer all customization until after Day 90. Most plants that miss the 75-day target fail on scope creep rather than technical complexity.
Book a scoping call to see your realistic timeline.
What is the minimum data needed to start go-live preparation?
A list of active assets with names, categories, and locations, even a hand-written list works. Full OEM specifications and sub-component hierarchies are not required for go-live. Historical maintenance data improves analytics but is not blocking, and can be backfilled after the foundation is stable.
How do you handle the legacy CMMS during the 75-day transition window?
Legacy systems are kept in read-only mode for a minimum of 60 days post go-live. This lets the team discover any work order references, attachments, or historical records not captured in the migration scope. Decommissioning before 60 days creates avoidable recovery risk.
Can we run the rollout without bringing in external consultants or implementation partners?
Yes. The plant in this case used three OxMaint onboarding team members and six internal staff, with no third-party consultants.

What happens if we slip a phase, does the whole 75-day plan collapse?
No, but only if you slip the start date rather than the gate criteria. The plan is built on gate-based progression, not calendar progression. A two-week delay in Phase 1 simply moves Phase 2 by two weeks. What kills rollouts is forcing the next phase to start before its prerequisite gate passes.
Your go-live, structured
Most CMMS rollouts fail on sequencing, not technology
If you have ever started a CMMS deployment that drifted from 90 days to 9 months, you already know the pattern. The technology was not the problem. The sequencing was. A 30-minute conversation with the OxMaint team will walk you through the same 75-day structure used in this case study, mapped against your specific asset count, your existing data state, and your team capacity. No assumptions, no generic benchmarks, just the rollout plan your plant can actually execute.
