Most maintenance managers already believe a CMMS pays off. The harder part is proving it. Finance wants to know which gains are real, which can be measured, and which can be expressed in euros, and that question gets sharper when you're asking for budget, defending a system that hasn't met expectations, or deciding what to report on first. This research paper looks at CMMS benefits as reported by the people responsible for running those software projects in Portuguese companies, and it asks a question many vendors skip: how far do organisations actually go in measuring what they gain?
How CMMS benefits are perceived, measured and valued in practice
The paper draws on a questionnaire answered by Portuguese companies across different sectors, with one response per company from the person in charge of the CMMS project. Respondents rated a set of benefits commonly attributed to maintenance management software, from labour productivity and inventory control to legal compliance and energy use.
What makes the findings useful is the second layer. For each benefit, the authors track how explicit it really is, using a four-level scale that runs from "the benefit is perceived" up to "the benefit is evaluated in value (€)". That distinction is where most business cases succeed or stall. A gain your team can feel is not the same as a gain you can put in front of a CFO, and the paper shows clearly which benefits tend to stay at the level of impression and which ones companies manage to translate into money.
You'll also see a before-and-after view of eleven common maintenance problems, such as excess corrective work, inefficient planning and weak control of costs, as reported before and after a CMMS went live. One problem moved far less than the others, and the authors offer two plausible explanations that are worth reading if you're planning staffing alongside a software rollout.
Building a business case around maintenance cost control and equipment availability
If you're preparing to justify a CMMS investment, or trying to get more from one you already own, the paper helps you think about where the evidence is strongest. After reading it, you'll have a clearer view of:
- which benefits companies report most often, and which ones they rarely manage to quantify
- why benefits like maintenance cost control lend themselves to financial measurement more readily than others
- how preventive maintenance planning in a CMMS links to longer equipment life and better equipment availability
- the role of maintenance indicators, and why many companies still have room to improve how they define them
The authors also reflect on why some implementations fall short. Their view is practical: results depend heavily on how the system is introduced, and the gains are most visible where the rollout comes with sound procedures and attention to how maintenance is organised. For anyone who has watched a software project lose momentum after go-live, that perspective is a useful check before the next one.
Compliance and reporting
Two further themes stand out. The paper explains how a CMMS supports the control and recording of interventions tied to technical certificates, periodic inspections and audits. It also points to automated reports and indicators as the feature that does much of the work behind several of the benefits respondents described.
Research from academic study and maintenance consultancy
The paper was written by João Folgosa and João Nunes Marques of Navaltik Management, Lda., and published in July 2019. It builds on a 2018 master's dissertation on maintenance management software in the Portuguese market, completed at ISCTE-IUL, and adds a consultancy perspective on how the studied benefits can be obtained in day-to-day operations.
That mix is what gives it value for practitioners. You get survey data from people who manage maintenance, plus commentary from consultants who implement these systems. It is short enough to read in one sitting, with charts that make the patterns easy to take into a meeting.

It's a solid reference if you need to make the case for a CMMS, set realistic expectations for an implementation, or decide which results your team should start measuring.
