How it works
An IWMS is built from modules that share one data model: real estate and lease administration, space and occupancy management, maintenance and work orders, asset management, capital projects, and often energy and sustainability reporting. Because a floor, a lease and an asset are the same record in every module, a change in one shows up in the others.
Most deployments center on the system of record: which buildings the organization holds, what each lease costs and when it ends, how floors divide into rooms and seats, and which department is charged for them. That is why IWMS rollouts tend to be long, configuration-heavy projects that begin with drawings and data cleanup.
What an IWMS usually does not capture well is day-to-day demand: who actually comes in, on which days, and which teams need to sit together. Many organizations keep the IWMS as the record of supply and connect a workplace management system for booking, check-in and attendance data, then use that demand signal for planning.
What each IWMS module manages
The modules share one database, so a building, a floor or a lease is the same record everywhere. Few organizations deploy every module at once.
| Module | What it manages | Main owner | Decisions it supports |
|---|---|---|---|
| Real estate and lease management | Leases, rent, critical dates, options and portfolio costs | Corporate real estate and finance | Renew, exit or renegotiate a lease |
| Space management | Floors, rooms, seats, assignments and chargeback by department | Space planners and facilities | Where teams sit and who pays for space |
| Maintenance and work orders | Planned and reactive maintenance, service requests and technicians | Facilities and maintenance teams | Maintenance budgets and service levels |
| Asset management | Equipment and building assets through their life | Facilities and finance | Repair or replace, and capital budgets |
| Capital projects | Budgets, schedules and vendors for fit-outs and refurbishments | Project managers and real estate | Which projects go ahead, and when |
| Sustainability and energy | Energy, emissions and building performance data | Sustainability and facilities leads | Where to cut energy use and how to report it |
How to measure it
- List the decisions the IWMS must support (lease renewals, chargebacks, maintenance budgets, space plans) before comparing modules.
- Check data freshness: how often floor plans, seat assignments and headcount are updated, and by whom.
- Count the manual exports between the IWMS and other systems; each one is a place where records drift apart.
- Confirm whether occupancy in the IWMS comes from observed presence or from assigned seats, because the two give different answers in a hybrid office.
How to choose an IWMS
- The decisions it must support. List the decisions first, such as lease renewals, chargeback, maintenance budgets and space plans. Buy the modules those decisions need, not the full suite.
- Data migration. Ask how leases, drawings, space records and assets are loaded, who cleans them and how long it takes before teams trust the system.
- Floor plan handling. Check how CAD drawings are imported, how plans are updated after moves and who can edit them.
- Where occupancy comes from. Confirm whether occupancy means assigned seats or observed presence. In hybrid offices only observed data shows real demand.
- Integration with workplace tools. Check the API and connectors to booking, presence, HR and finance systems, so supply and demand data stay in step.
- Configuration over customization. Heavy customization slows upgrades. Ask which of your needs the product meets through configuration alone.
- Identity, security and hosting. IT should confirm single sign-on, user provisioning, role-based access, independent security certifications and where data is hosted.
- Total cost and time to value. Compare licenses, implementation partner fees, data work and internal staff time, and ask how long the first working module usually takes.
Examples
- A bank tracks its leases, critical dates and departmental chargebacks in its IWMS, while a desk booking platform supplies daily attendance for the same floors.
- A university runs planned maintenance and capital projects in its IWMS and imports room-level space data each term.
Common mistakes
- Buying every module at once, which turns the rollout into a multi-year data project before anyone sees value.
- Treating assigned seats in the IWMS as occupancy. In hybrid offices, assignment and attendance diverge.
- Updating floor plans and seat records by hand after moves, so the system of record falls behind the building.
- Expecting an IWMS to handle employee-facing booking and team coordination it was not designed for.
How Kadence helps
Kadence is designed to sit alongside an installed IWMS as the planning and execution layer. WorkOps captures demand (desk and room bookings, check-ins and attendance) and reports it in Workplace Insights. SpaceOps uses that occupancy data for stack plans, scenario planning and space plans, and the public REST API, outbound webhooks and data export pass the results to other systems.

Frequently asked questions
What is the difference between IWMS and CAFM?
CAFM focuses on facilities operations: space inventory, floor plans, maintenance and service requests. An IWMS includes those and adds real estate and lease management, capital projects, asset lifecycle and often sustainability reporting on one shared database. Many IWMS products began as CAFM tools and grew outward, so the labels overlap.
Is an IWMS the same as a workplace management system?
No. A workplace management system runs the daily use of the office: desk and room booking, visitors, check-in and attendance reporting. An IWMS manages the portfolio behind it: leases, space records, maintenance and assets. Many organizations use both and connect them, so the IWMS holds supply and the workplace system measures demand.
What is the best IWMS software?
The best fit depends on the decisions you need to support. Organizations with large leased portfolios and in-house maintenance teams need strong lease and work order modules. Hybrid offices also need reliable attendance and booking data, which many IWMS products do not collect, so check how the system connects to booking and presence tools before you choose.
Does an IWMS work for hybrid offices?
It works as the record of buildings, leases and space, but most IWMS products were built for assigned seating. In a hybrid office the key planning input is who actually comes in and when. That data comes from bookings, check-ins and presence signals, so hybrid organizations usually pair the IWMS with a workplace management system.
What should I look for when replacing a legacy IWMS?
Separate the two jobs an IWMS does. Leases, assets, maintenance and capital projects need a system of record, and many teams keep the IWMS for those. Daily workplace tasks such as desks, rooms, visitors and moves often move to a simpler platform that imports your floor plans and that employees use without training. Ask how long setup takes per office and who maintains it after go-live.
