Understanding the Difference Between CMMS and APM

Note that not all CMMS and APM have the same functionalities – therefore, this article is based on our experience and applies for most software solutions. 

In the world of maintenance and asset management, two software systems, CMMS (Computerized Maintenance Management System) and APM (Asset Performance Management), play vital roles.  

Often, these two software solutions are mistaken one for another. This article will help clarify the difference between them. CMMS primarily focuses on day-to-day maintenance tasks, inventory management, and labor management, while APM is geared toward optimizing asset performance, including predictive maintenance, data analysis, and machine learning. This article explores these distinctions, integration capabilities, and performance indicators, shedding light on their unique contributions to the industry. 

Understanding CMMS and APM 

• Maintenance is a cornerstone of any industrial operation, ensuring that equipment runs efficiently and downtime is minimized. CMMS, often used interchangeably with Enterprise Resource Planning (ERP), is designed to streamline and manage maintenance activities and manage parts inventory. It excels at work order management, inventory management, labor management, and in some cases, financial and accounting tasks related to plant assets. 
• On the other hand, APM (Asset Performance Management) is used to manage assets performance and its primary purpose is to optimize the overall reliability and equipment effectiveness of the plant. The assets performance could be based on different aspects such as preventive maintenance results, predictive maintenance results, process data, or machine learning.

The Reality: Day-to-Day vs. Big Picture 

• CMMS is the go-to choice for day-to-day maintenance tasks. It excels in executing corrective work orders, managing spare parts, and scheduling maintenance resources efficiently. CMMS is essential for ensuring that maintenance operations run smoothly on a daily basis. 
• In contrast, an APM will look at the bigger picture rather than day-to-day maintenance activities. It zooms out from the daily maintenance activities to focus on tracking asset health, identifying problematic equipment (bad actors), and recognizing common failure patterns. APM seeks to address the root causes of failures, thereby improving asset performance and reliability over time. 

Integration with Other Systems 

• CMMS programs often operate as standalone systems due to the sensitive and critical nature of the data they handle. When integration does occur, it typically links with financial, accounting, procurement, and historian platforms to maintain data integrity and support various aspects of plant operations. 
• Conversely, APM thrives on integration. It seamlessly connects with multiple platforms to gather valuable data related to asset health and performance. APM often collaborates with predictive and preventive platforms, including vibration live monitoring, oil analysis labs, and IoT platforms. Moreover, APM APM also often can connect to the plant’s CMMS to gain work order and parts management insight. 

Performance Indicators: KPIs and Analytics 

• CMMS platforms usually provide a limited number of key performance indicators (KPIs). These KPIs are often not readily available within the platform and require data manipulation to extract meaningful insights. CMMS mainly focuses on operational metrics, such as work order completion rates and maintenance costs. 
• In contrast, APM are more advanced when it comes to KPIs and analytics. Most APM solutions include automated KPIs, with a focus on centralized preventive and predictive maintenance results. Common APM KPIs encompass asset health assessments, identifying bad actors, highlighting frequent failure modes, and ensuring compliance with maintenance schedules and routes. More advanced APM will also provide predictive analytics and machine learning to predict potential failures and adapt maintenance strategies proactively. 

Gap Analysis: CMMS vs. APM 

Currently, the majority of industrial plants have adopted CMMS systems, while APM software is less common. CMMS excels in managing day-to-day activities, providing guidance on reactive and preventive maintenance, parts inventory management, and scheduling. However, one critical limitation of CMMS when it comes to performing maintenance activities, is its inability to seamlessly bring data back into the platform, hindering the ability to qualify and quantify maintenance efforts. 

Maintaining asset health and identifying bad actors become challenging when relying solely on CMMS. Many plants resort to using spreadsheets to track this crucial data, but spreadsheets have their drawbacks. They operate in silos, require a lot of human intervention, they are not fully automated and are often forgotten about when day-to-day emergencies happen. 

This is the gap that an APM is covering. When effectively implemented, APM systems automatically generate key metrics, such as asset health and bad actor identification. They consolidate data from various preventive and predictive maintenance technologies into a centralized platform.  

It will allow you to easily access different preventive and predictive maintenance technology results under one centralized platform. Ultimately, having all of this information will empower organizations to address recurring failure at its source, enhancing overall reliability and boosting equipment performance and availability. 

In conclusion, understanding the differences between CMMS and APM is crucial for optimizing maintenance and asset management in industrial settings. While CMMS is indispensable for daily operations, APM takes a holistic approach, enabling proactive asset performance enhancement. APM’s integration capabilities, advanced KPIs, and data-driven decision-making offer a powerful solution for addressing maintenance challenges and elevating overall operational efficiency. By embracing the unique strengths of both CMMS and APM, organizations can achieve a balanced and comprehensive approach to maintenance and asset management in today’s complex industrial landscape.
