Inadequate maintenance and risk mitigation processes can quickly undermine a facility’s design intent. It is, therefore, crucial to understand how to properly structure and implement an operations and maintenance (O&M) program to achieve the expected level of performance. This paper defines a framework, known as the Tiered Infrastructure Maintenance Standard (TIMS), for aligning an existing or proposed maintenance program with a facility’s operational and performance requirements. This framework helps make the program easier to understand, communicate, and implement throughout the organization.
An organization’s cost of downtime and risk-tolerance level must first be established in order to determine which TIMS level best matches their goals. This knowledge is a prerequisite for the development of a realistic maintenance program. Ultimately, the TIMS level achieved will be determined by resource availability and the commitment of the organization’s management team to implement and maintain the program over the long term.
When evaluating the entire scope of the mission-critical enterprise, the effectiveness of the maintenance program is one of the key components that must be factored in to determine the true level of sustained reliability. The tremendous variability in how maintenance is implemented can make it difficult to judge what constitutes the proper level of service in a given situation. Defining maintenance levels and using that to evaluate a given O&M program as described in this paper is a tool to achieving such an understanding.
The Tiered Infrastructure Maintenance Standard offers a systematic approach to matching maintenance activity levels with the level of reliability expected of the facility. Applying these principals to your maintenance program is a crucial step in attaining data center availability and business continuity goals.
