Organisations like yours, with mission-critical needs, critical time constraints and critical customer bases.

What our clients say

TCM Services

We go beyond the provision of service. At TCM we build solutions that suit our customer’s every need. Our expert consultancy is backed by our ISO/ITIL accredited Service Management function, which ensures we remain in touch with our customers’ current and future NonStop needs.


NonStop Systems Management is at the core of everything TCM does. For 20 years, the management of NonStop systems has been our company’s primary focus, amassing unrivalled levels of experience and expertise in this critical, niche environment.


Our Professional Services encapsulate the range of activities, consultancies and projects which support the core systems management of your NonStop estate. These are the routine, yet critical undertakings that call for specialist resource and experience.


Lifecycle Services are those longer-term considerations that should be taken at periodic intervals along the lifetime of a NonStop system. Unfortunately, they are often neglected out of the necessity to deal with the pressure and concerns in the immediate term of the NonStop.
