Ever find yourself mixing up "installation" and "commissioning"? You’re not alone. These two terms are often used interchangeably on projects, but they actually refer to very different phases of delivery - each with its own role, challenges, and outcomes. If you're involved in deploying systems or equipment, whether in mining, manufacturing, construction, or energy, understanding the difference can help you better manage timelines, costs, and customer expectations.
Let’s break it down.
Installation is the phase where all the physical components come together. It’s when technicians or contractors follow engineering drawings and specs to mount, wire, connect, and assemble the system or equipment on-site. Think of it as the “build” phase.
Whether it’s installing hardware on 70 mining trucks or wiring up a factory control system, installation is about putting things in place and making sure it matches what was designed.
Key characteristics of installation:
It’s a critical part of the project, but it doesn’t tell you whether the equipment is actually ready to use.
Commissioning starts once installation is complete. It’s the phase where everything gets tested, validated, and signed off. The goal is to make sure the system works as intended - safely, reliably, and efficiently.
Commissioning includes function checks, calibrations, software configurations, system integrations, and final validations. It’s about proving performance, not just completion.
Imagine building a car. Installation is putting the engine, wheels, and electronics in place. Commissioning is turning the key, testing the brakes, checking emissions, and making sure it’s roadworthy before handing it over to the driver.
Understanding the difference between installation and commissioning isn’t just technical jargon - it can have a real impact on your business. Projects often get delayed or disputed because commissioning steps weren’t clearly defined or treated as an afterthought.
Poor commissioning processes lead to:
While they’re distinct phases, installation and commissioning need to work hand-in-hand. The smoother your installation, the easier your commissioning. But they require different skills, checklists, and workflows.
In high-performing teams, installation ends with all components in place, and commissioning picks up with a systematic review to ensure everything is working exactly as it should.
Installation gets your equipment into the field. Commissioning proves it’s ready to deliver. Treating both as critical—but separate—phases of your delivery process can help you avoid project delays, improve customer satisfaction, and speed up revenue recognition.
