Reliability Maturity Matrix stage descriptions - FMS Reliability

  1. 1. f msreliabilit y.com http://www.fmsreliability.com/education/reliability-maturity-matrix/ Fred Reliability Maturity Matrix Maturity Matrix The concept of a maturity model is not new. It provides a means to identif y the current state and illuminate the possible improvements to a reliability program. The matrix serves a guide to assist an organization in improving its program. The matrix has f ive stages. In general, the higher stages are most cost ef f ective and ef f icient at achieving higher rates of product reliability perf ormance. These stages—uncertainty, awaking, enlightenment, wisdom, and certainty—are described in today’s post. Stage 1: Uncertainty “We don’t know why we have problems with reliability.” Reliability is rarely discussed or considered during design and production. Product returns resulting f rom f ailure are considered a part of doing business. Field f ailures are rarely investigated, and of ten blame is assigned to customers. The f ew people who consider reliability improvements gain little support. Reliability testing is done in an ad hoc f ashion and of ten just to meet customer requirements or basic industry standards. Stage 2: Awakening “Is it absolutely necessary to always have problems with reliability?” Reliability is discussed by managers but not supported by f unding or training. Some elements of a reliability program are implemented, yet generally not in a coordinated f ashion. Some tools such as FMEA and accelerated and highly accelerated lif e testing are experimented with, but most ef f ort still f ocuses on standards-based testing and meeting customer requirements. Some analysis is done to estimate reliability or understand f ield f ailure rates, yet limited use is made of these data in making product decisions. There is, however, an increasing emphasis on understanding f ailures and resolving them. Failure analysis is typically accomplished by component vendors with little result. Stage 3: Enlightenment
  2. 2. “Through commitment and reliability improvement we are identif ying and resolving our problems.” A robust reliability program exists and includes many tools and processes. Generally, signif icant ef f ort is directed to resolving prototype and f ield reliability issues. Increasing reliance is placed on root-cause analysis to determine appropriate solutions. Some tools are not used to their f ull potential owing to lack of understanding of reliability and how the various tools apply. Some reliance is placed on establishing standard testing and procedures f or all products. Only some use of these testing results is made f or estimating product reliability to supplement predictions. Predictions are primarily made to address customer requests and not as f eedback to design teams. Stage 4: Wisdom “Failure prevention is a routine part of our operation.” Each product program or project has a tailored reliability program that can be adjusted as the understanding of product reliability risks changes. Reliability tools and tasks are selected and implemented because they will provide needed inf ormation f or decisions. Testing f ocuses on either discovering f ailure mechanisms or characterizing f ailure mechanisms. Testing of ten proceeds to f ailure, if possible. Advanced data analysis tools are regularly employed and reports are distributed widely. There is increasing cooperation with key suppliers and vendors to incorporate the appropriate reliability tools upstream. Stage 5: Certainty “We know why we do not have problems with reliability.” Product reliability is a strategic business activity across the organization. There is widespread understanding and acceptance of design f or reliability and how it f its into the overall business. Product reliability is accurately predicted prior to product launch using a mix of appropriate techniques. New materials, processes, and vendors are caref ully considered f or their ability to meet internally established reliability requirements. The f ew f ailures that do occur are expected and analysis is done to identif y early signs of material or process changes. Customers and suppliers are regularly consulted on ways to improve reliability.
