Introduction to Maintainability Online Training Course

This course was developed by Quanterion Solutions Inc. under the DoD Reliability Information Analysis Center (RIAC) Contract as an introduction to maintainability engineering concepts and practices. It begins with a brief overview of the RIAC, and because maintenance demand is driven by system reliability, provides an overview of basic reliability engineering concepts before proceeding into the core maintainability topics. Section 3 begins the core content by covering basic maintainability concepts and definitions, the need for maintainable systems and the elements of a comprehensive maintainability program. Section 4 covers the basic mathematical foundations of maintainability by describing various probability distributions that are commonly used to model system maintainability. Section 5 describes establishing maintainability requirements at the system level as well as at lower levels of design. These include establishing quantitative requirements, such as mean time to repair (MTTR), as well as techniques such as quality function deployment (QDF) that are used to ensure user requirements are met. Section 6 delves into maintainability design techniques such as allocations, predictions, human engineering and standardization. Section 7 covers maintainability verification approaches, including inspection, analytical methods and testing. Section 8 describes trending methods to track and improve maintainability over time and Section 9 discusses ensuring maintainability is not degraded by production decisions. Section 10 provides a review and wrap-up of the course.
