Availability, Reliability and Maintainability (ARM) Studies

ARM Assessments identify areas of a design that are over or under-designed, allowing designers to strengthen the design where necessary or to make economic savings by scaling back in areas that are overly robust.

ARM studies also investigate maintainability issues to identify the access and resource requirements that will allow component reliabilities to be maintained throughout the life of the equipment.

We have over 15 years’ experience offering ARM services, both in support of competitive tenders and during detailed design following contract award.

Example: ARM Assessment of a Fire Service Management System

Client: Thales UK

Egerton Consulting was appointed to carry out an ARM assessment of the Thales FiReControl design tender.

The assessment provided assurance that the majority of the design elements would meet the availability targets proposed but highlighted one area where the target would not be met and identified what improvements would be required to achieve the target.

This information allowed Thales to go into subsequent discussions with their client (the ODPM) with a better understanding of the costs of meeting ALL targets. It also gave them a basis for negotiating target changes which they were confident could be met cost-effectively.

Thales were subsequently selected as joint suppliers of FiReControl.
