What is work and asset management (WAM)?
Updated · Reviewed by Israel Margulies, founder and CEO of High Point GPS
Work and asset management (WAM) is the practice, and the software, that ties every maintenance job to the asset it was done on, so you can see what you own, what shape it is in and what it costs to keep running. A CMMS covers the work side well and some of the asset side. An EAM covers both across many sites and adds capital planning and finance. Oracle also sells an enterprise product called Utilities Work and Asset Management, which is a separate thing from the general term.
Two halves of one job
Work management is the daily flow: someone reports a problem or a service comes due, a planner turns it into a work order, a supervisor schedules it, a technician does it and closes it with notes, parts and hours. Asset management is the longer view: the register of every machine, its condition, its cost to date and the point where you should stop repairing it and replace it.
You can run either half on its own. Plenty of shops track jobs on a whiteboard and keep the asset list in a separate spreadsheet. The trouble starts when you need an answer that crosses the two, such as which loader has eaten the most repair hours this year, or whether the truck you plan to keep has had the same brake complaint four times. Those answers only exist when each closed job is filed against a specific asset ID.
Oracle WAM and the generic term
If you searched for work and asset management because your utility runs Oracle, you are looking at a named product. Oracle describes Utilities Work and Asset Management as supporting the full asset lifecycle, with cloud or on-premises deployment and built-in asset performance management that uses condition data and AI for predictive maintenance planning. It sits in the enterprise asset management (EAM) class and targets utilities.
Outside that product, people use the phrase for any setup that joins maintenance work to asset records. Other enterprise vendors use similar names. The rest of this guide treats WAM as the practice, because the questions about how to run it are the same whichever software you pick.
What the work side has to capture
The asset side can only learn from what technicians write when they close a job. A job closed with "done" and nothing else leaves the machine's record empty. Decide up front what every closed job must carry, and set the system to refuse a close without it.
- The asset ID, picked from the register rather than typed free
- Planned or unplanned, so you can measure your preventive share later
- A problem, cause and remedy code on every repair
- The meter reading at completion (hours or miles)
- Parts used, labor hours and any outside vendor charge
- Downtime start and end, if the machine was out of service
What the asset side has to hold
ISO 55000 is the international standard series for asset management. Its 2024 edition gives the overview, principles and vocabulary; ISO 55001 sets the requirements for an asset management system and ISO 55002 gives guidance on applying it. You do not need certification to borrow its central idea: manage each asset over its whole life so it delivers what the organization needs at a cost and risk you have chosen on purpose.
For an equipment fleet, that turns into a register with a few fields that rarely get filled in at the start: purchase date and cost, expected life in hours or miles, criticality, warranty end date and the home location. With those in place, the work history on each machine adds up to a lifetime cost you can compare against its replacement price.
Where CMMS and EAM sit
The CMMS vs EAM comparison on this site goes through the two classes feature by feature, so this section covers only the practical test: who will use the system on a Tuesday. If the answer is technicians, a shop supervisor and one manager, a CMMS with good asset records covers your WAM needs. If finance, capital planning and several regional maintenance groups all need to work in the same records, you are in EAM territory and should plan for a longer rollout.
Hypothetical example: a contractor with 60 machines and two yards has one shop, one parts room and one person who signs off on replacements. Clean work orders and a complete register answer every question that owner asks. A capital planning module would sit unused, and its setup would take time away from getting codes and meter readings right.
Signs you need more than a CMMS
You have outgrown a CMMS when people outside maintenance need to work in the asset records. Check your organization against this list; if none of these apply, stay with the simpler system.
- Asset decisions are made in a capital plan that spans many years and needs depreciation from the same records
- Several divisions or utilities share assets and must charge work to each other
- A regulator asks for an asset management plan with condition ratings and risk scores
- Purchasing and inventory run through an ERP that must own the part numbers
- You have staff to configure and run the system, not only to use it
Getting usable data out of WAM
The US Department of Energy’s O&M Best Practices Guide says a CMMS does not make decisions, it gives the manager the information to make them. The guide lists the usual reasons maintenance systems fail: the wrong vendor for the site, too little training for the people entering data, and no one inside the organization who keeps pushing its use after go-live.
Data quality comes down to a few habits. Name assets the same way everywhere. Log meter readings on a fixed rhythm so intervals and cost per hour mean something. Review a sample of closed work orders each week and send back the ones with missing codes. Give that routine three months before you trust the reports for replacement decisions.
Work and asset management in FleetZap
FleetZap is a CMMS built for equipment fleets, with the asset pieces a fleet owner needs. Every work order hangs off an asset, and the asset page keeps the full history: jobs, status changes with reasons, meter readings, parts and cost. Repairs carry problem, cause and remedy codes, and the failure analysis report shows top problems and repeat offenders.
On the asset side you get criticality, warranty dates with alerts, sub-assets whose costs roll up to the parent, nested locations, lifetime and 12-month maintenance cost, cost per hour, a retire-by forecast and a keep, watch or replace verdict. Preventive schedules open work orders by hours, miles or calendar, and readings come from technicians, rental returns or connected GPS trackers. Capital planning and general ledger accounting stay in your finance system.
Key takeaways
- Before go-live, write the list of fields a closed job must carry and test that the system blocks a close without them.
- If you can't name a person outside maintenance who needs the asset records weekly, buy a CMMS and spend the difference on data cleanup.
- Back-fill purchase cost and expected life for your 20 most expensive machines first; those are the replacement calls that pay for the effort.
- Track the share of closed repairs missing a cause code each month; when it stops falling, retrain the people closing jobs before you change any report.

Frequently asked questions
What does WAM stand for in maintenance?
WAM stands for work and asset management. It covers the flow of maintenance work, from request to closed work order, together with the records of each asset that work is done on. Oracle also uses the name for its Utilities Work and Asset Management product, an enterprise system aimed at utilities. In general use, it means any setup that links jobs to assets.
Is Oracle WAM a CMMS or an EAM?
Oracle positions Utilities Work and Asset Management as a full asset lifecycle product for utilities, with investment planning and built-in asset performance management, which places it in the enterprise asset management class. A CMMS focuses on work orders, preventive maintenance, parts and history. Many smaller fleets need only that, plus good asset records, rather than an enterprise suite.
What is the difference between work management and asset management?
Work management handles individual jobs: requests, planning, scheduling, doing the work and closing it with parts, hours and notes. Asset management looks at each machine over its whole life: condition, total cost, risk and when to replace it. Asset decisions depend on the job history, so the two only work well when every job is recorded against a specific asset.
Does a small fleet need work and asset management software?
A small fleet needs the practice more than a big software suite. Once you have more machines than one person can remember, a CMMS that ties work orders to an asset register gives you service history, cost per machine and due preventive work. Enterprise WAM systems make sense when finance, capital planning and several sites must share the same asset records.
