Assessing Reliability

The Importance of Reliability

Reliability is paramount when selecting displays for your control room environment. Although initial cost or capital expenditure is important, the real cost of your investment is related to Total Cost of Ownership.

In order to determine the Total Cost of Ownership of your display video wall or visualization wall system, additional expenditures must be considered. These expenditures include consumables, maintenance, service intervals, and most certainly, the reliability of the displays.

Reliability is often calculated in MTBF or mean-time-between-failure. MTBF can be defined as the average amount of time between failures. When determining a system’s MTBF, all components must be factored in.

Another key indicator of reliability is the warranty burden of a given product or product line. If a manufacturer offers a “bumper-to-bumper” warranty, they should also provide replacement parts and lamps upon failure to fulfill their commitment. The cost associated with this is known as warranty burden and although it is important to know what their costs of doing business is, it also indicates the reliability of the system’s components. The lower the warranty burden, the lower the cost and the higher the reliability.
