The technician picks up the job, works the checklist, logs parts, photographs the outcome, and signs off — all from the device they carry.
The gap between the work order in the CMMS and the technician in the field has always been the weakest link in maintenance management. The technician gets a job number and a description on a paper printout, or a call from the coordinator, or a note on a whiteboard. They carry out the work. At the end of the shift, someone enters the outcome in the system — or doesn't, and the work order stays open until someone chases it. The information flows in one direction: job briefing from the system to the technician. What the technician knows — the actual fault, the parts used, the time taken, the condition of the equipment, the photos they took on their personal phone — rarely makes it back to the system in any structured way. Coreziyo's mobile execution capability reverses this. The technician's phone is the interface. They receive the job brief with the full asset record, accept the job, navigate to the location, work through the configurable checklist, photograph the work in progress and on completion, log the parts they consume, and sign off digitally. Every step is captured in real time. When the job closes, the work order is complete, the asset history is updated, the parts draw is posted, and the cost is allocated — all from the field, without a back-office re-entry step. For the broader mobile capabilities covering asset scanning, parts lookup, and inspection workflows, see [Mobile Field App](/features/cafm/mobile-app/).
Mobile execution is not about putting a CMMS interface on a phone. It is about making the field the primary data source rather than the end of a paper trail. When the technician’s device is the system of record for what happened at the asset, the data is captured at the moment of maximum accuracy — during or immediately after the work, while the details are fresh and observable.
The alternative — paper records, verbal confirmation, end-of-day data entry — introduces delay, error, and incompleteness. At the scale of 150,000+ work orders a month, these errors accumulate into reporting that nobody trusts and cost records that nobody relies on.
Coreziyo’s mobile execution model makes the technician an active contributor to the operational record, not a passive executor of paper instructions. The quality of maintenance data improves because the people closest to the work are the ones recording it, in real time, on the device they already carry.
What you actually get
Push job notifications and acceptance
Technicians receive push notifications when a job is assigned. They accept or flag a conflict from the notification, with real-time visibility to the dispatcher. Job acceptance is tracked and timestamped — no phone calls to confirm who has picked up what.
Full asset record on-device
Before starting the job, the technician can review the asset's full history: previous maintenance, open faults, last condition score, and any active warranty or permit-to-work requirement. The brief is complete before they pick up a tool.
Configurable maintenance checklists
Each job type carries a configurable checklist — steps the technician must complete and confirm before closing. Checklists ensure consistent execution across a team of 3,900+ technicians without supervisor presence at every job.
Photo and video evidence capture
Photos and video are captured in the mobile app and attached to the work order permanently. Before-and-after photos, fault evidence, and completion records provide the documentation that clients and auditors require — captured in the field, not reconstructed later.
Parts consumption and digital sign-off
Technicians log spare parts consumed from the mobile app. The draw posts against the work order cost and updates inventory in real time. Client or supervisor signs off digitally on the same device, completing the chain of custody.
How it shows up in real operations
A GCC FM operator deploying 3,900+ technicians across 1,000+ buildings cannot supervise every job in person. The consistency of execution — the right checklist steps completed, the right parts logged, the right photographic evidence captured — has to come from the system, not from supervisory presence. In Coreziyo, a maintenance technician in the field receives a PPM notification for a rooftop HVAC unit. They navigate to the asset using the embedded location reference, scan the QR code to confirm they are at the right unit, work through the seventeen-point checklist, photograph the filter condition before and after replacement, log the filters consumed from inventory, and sign off. The coordinator sees the completion in real time. The asset record is updated. The cost is posted. The supervisor never needed to be there.
