MTBF as maintenance metric can help decide the suitable timeframe for equipment downtime for maintenance activities. This helps with budgeting for a replacement/upgrade as it helps determine when it will reach its end of life and need replacing. MTBF metrics allow maintenance teams to make informed decisions by giving a quantitative estimate of when and how often an asset is expected to fail before it does. Since MTBF is a measure of a system’s reliability, it can be used in various important business decisions, including KPIs, which are helpful to know how well your company is doing and how to improve future performance. The Five Whys is an effective method for discovering the root cause of problems and developing long-term solutions to prevent them from recurring. When a machine does experience failure, an Root Cause Analysis study can help find the root of failures and develop solutions to prevent them from happening again. If all employees use standardized data, they understand how their work relates to others’ efforts, and they can easily see where gaps exist and collaborate to close them. This enables organizations to make more informed decisions about their overall asset portfolio.ĭata standardization also helps improve the communication between different departments within an organization. Data standardization allows you to compare assets across multiple sites, locations, and periods. This is critical for an asset care strategy. Standardizing maintenance data provides reliable, accurate, and timely information on an asset’s performance to improve operational and strategic decision-making. RCM also gathers information about critical assets and which ones may require more attention than others to create a plan of action. This knowledge helps to understand why equipment fails and how to optimize the repair process. It includes examining how a piece of equipment operates and how the equipment is designed. Reliability Centered Maintenance, or RCM, is a reliability methodology that develops asset management strategies that help ensure equipment is available when needed, especially critical equipment. Preventive maintenance programs can help to avoid costly downtime by reducing the risk of failure and increasing the reliability of an asset, thereby increasing the average time between failures. Processes like continuous monitoring, preventive maintenance, and regular testing can ensure that an asset still is reliable throughout its lifecycle. One method to improve MTBF is through process improvements. However, the calculation can be improved by reviewing the systems and making the appropriate changes. Many factors affect your MTBF calculation, such as age, operating conditions, and usage patterns. In general, MT BF is a measure of reliability, whereas MT TF is a measure of longevity. MT BF is the average time a product or component will work without any issues or failures, whereas MT TF is the average time a product or component will fail. MT BF ( Me an Time Between Fail ures ) and MT TF ( Me an Time To Failure ) are two terms used to measure the average lifetime of a product or component. The appropriate number should be considered case-by-case and varies depending on the asset, use case, environment, and the maintenance program that is in place. The goal should be to have a high average time between failures, indicating good health. It helps to plan around this so that when a failure does happen, you can respond with the correct asset management strategy. ![]() This translates into lower costs associated with repairs and unplanned downtime.Ī lower MTBF output means you will likely experience a more frequent failure rate. What the results meanĪ high MTBF output means fewer problems with your equipment will occur over its lifetime. It may include any failure, including mechanical, electrical, software, or human error. Total breakdowns are the number of times the equipment has failed while running. It includes both planned maintenance tasks and unplanned repair time. Typically this is measured in operating hours. Total operational time is the period your equipment runs without any breakdowns. The following formula is used to calculate MTBF: Total Operational Time / Total Number of Breakdowns = MTBF (hrs.) Many companies aim to maximize output and minimize downtime during regular operating hours. \) in Section 2.3.For many organizations, knowing MTBF metrics helps assess the reliability of the systems that support your business operations. ![]()
