If you’re new to FM software, grappling with acronyms like CAFM (Computer Aided Facility Management) and IWMS (Integrated Workplace Management System) is enough to leave anyone feeling puzzled.  

To make matters even more confusing, both FM software solutions appear similar on the surface, however they each have their own distinct purpose and nuances.  

Not to worry: to help you understand what sets both CAFM and IWMS software apart, SFG20’s technical experts have put together this jargon-free guide which will give you an overview of both platforms, covering key differences alongside pros, cons and costs.  


What Is Computer-Aided Facility Management (CAFM)? 

Computer-Aided Facility Management (CAFM) is a software platform that provides a digital centralised overview of all your important facilities management operations. It automates key functions and allows you to manage a building's assets, tools, processes and occupants within a building, all from one platform.  

From space and asset management to planned preventive maintenance and property lease management, CAFM systems put the power in your hands to schedule maintenance tasks, monitor assets as well as organise data and track work orders.  

Instead of relying on complicated spreadsheets and physical documents prone to getting lost, a CAFM enables you to log, report and monitor data while overseeing the day-to-day running of your facility. 


Who Are CAFM Systems For?

CAFM software is primarily used by people within facility management teams and departments, as it enables the management of the workplace and the potential maintenance of building elements.

Due to its versatility, CAFM software is employed across a diverse range of organisations and industries including those within the government, healthcare, education and retail sectors. 


What Are The Key Features/Uses of CAFM? 


Space Management 

When combined with CAD (Computer-Aided Design) and BIM (Building Information Modelling) software, CAFM can provide graphical representations of facility layouts, enabling users to track occupancy and optimise space utilisation. CAFM systems can also help to monitor room capacity and movement, allowing you to identify how frequently spaces are being used.  


Move Management 

CAFM systems can aid with planning, executing and tracking the moves of equipment, furniture and people from one location to another. 


Asset Management 

CAFM software can be utilised to track and maintain assets and equipment, allowing users to schedule maintenance activities and monitor/track their conditions and performance over time.  


Room Reservations 

CAFM systems typically include a room reservation module that allows you and your team to easily book and manage meeting rooms and other shared spaces. This feature provides real-time visibility into room availability and occupancy status, preventing double bookings and over-bookings. 


Inventory Tracking 

With a CAFM system, you can monitor stock levels and consumption rates of consumable items such as office supplies and cleaning materials. The system can also automate restock requests and track inventory movements and locations, ensuring efficient inventory management. 



Contractor Management 

CAFM systems enable you to oversee and collaborate with external contractors and subcontractors. By maintaining records of contractor certifications, licenses and insurance details, the system helps verify compliance with relevant regulations. 


Real Estate Management 

CAFM systems store and maintain accurate records of lease, rent and tenure agreements, along with associated data such as critical release dates, terms, renewal options and costs. You can also configure the system to send automated notifications to alert you of upcoming lease renewals, expirations and other critical information.


Maintenance Management 

While not all CAFM systems include maintenance modules, those that do offer valuable features such as scheduling and tracking both preventive and reactive maintenance tasks. They allow you to oversee and manage the complete work order lifecycle from creation to assignment and completion as well as track maintenance histories and performance data to support proactive maintenance strategies. 


What Are The Pros Of Using A CAFM System? 


Reduced Costs 

CAFM systems provide accurate operational data, enabling quicker, more informed decisions, better resource management and extended asset life, all of which being able to reduce operational costs. If your CAFM system has a maintenance module which can recognise compliance (or statutory) tasks, it can also help you to avoid fines and penalties for safety hazards and equipment failures.  


Increased Asset Lifespan 

Proactive management of assets and equipment maximises their lifespan, reducing the need for costly replacements and minimising downtime. 


Accurate Data 

CAFM systems are built on real-time data and analytics, capturing and storing various forms of built environment information and serving as a single point of reference. This ensures informed, strategic decision-making alongside useful report generation which can provide actionable insights and allow you to track key performance indicators. 


Data Integration 

Advancements in software development have now made it possible for CAFM software to be integrated with other data streams and platforms such as CMMS, IoT sensors, ERP systems, BIM/Digital Twins, CDEs and SFG20’s smart new software solution Facilities-iQ.
