Our Operating System

Our Operating System


UTC fosters a culture of continuous improvement. We use our ACE operating system to achieve the highest levels of performance in everything we do, from developing new products to finding better ways to serve our customers.

Achieving Competitive Excellence (ACE)

ACE is the UTC operating system. It focuses on the drivers of competitive excellence — our people and our work processes. Our leadership and empowered employees work together to implement ACE practices in all of our activities across every UTC business to benefit our customers and shareowners.

ACE has three elements: culture, tools and competency. The daily interaction of each element is what makes it an operating system. Results focus on perfect quality, on-time delivery, highly engaged employees working in a safe environment, and best-in-class financial returns.  

We are committed to consistently delivering ACE benefits to our customers, employees and shareholders.
