Maintainability has extensive effect on the Life Cycle Cost (LCC) and Levelized Cost of Energy (LCOE). This chapter brings together many of the elements that affect the ability to maintain PV equipment and introduces the basic mathematics of maintainability. It addresses the various stages of maintenance, factors that affect the assessment of those stages, and presents examples of elements that are sometimes over looked. Considerations that must be accounted for are factors such as, work space around modules or strings, accessibility to connections, safety of access, and ease of trouble shooting (testability). Aside from providing access for maintenance personnel, it is necessary to consider what type and size of support equipment that may be needed to perform maintenance.

This report summarizes how to systematically analyze a software architecture with respect to a quality attribute requirement for maintainability. The report introduces maintainability and common forms of maintainability requirements for software architectures. It provides a set of definitions, core concepts, and a framework for reasoning about maintainability and the satisfaction (or not) of maintainability requirements by an architecture and, eventually, a system. It describes a set of mechanisms, such as patterns and tactics, that are commonly used to satisfy maintainability requirements. It also provides a method by which an analyst can determine whether an architecture documentation package provides enough information to support analysis and, if so, determine whether the architectural decisions contain serious risks relative to maintainability requirements. An analyst can use this method to determine whether those requirements, represented as a set of scenarios, have been sufficiently well specified to support the needs of analysis. The reasoning around this quality attribute should allow an analyst, armed with appropriate architectural documentation, to assess the risks inherent in today’s architectural decisions in light of tomorrow’s anticipated needs.

There were five major technical reports produced as a result of research on this Task Order. Reports no. 1, 2, 3, and 5 deal directly with the subject of Maintainability. Report no. 4 deals only indirectly with maintainability but does assess optimal stocking quantities for items which are subject to deterioration over time.

This paper reexamines information system (IS) maintainability and takes a new and inclusive view of it and its effects. It proposes that an IS is maintainable to the extent that its maintenance, operation, and use is economical in its use of resources. A model is offered which puts IS maintainability in the larger developmental context and suggests a number of related propositions. To the question of whether increased maintainability should reduce an organization's maintenance effort, a straightforward analysis leads to what, for some, may be a surprising answer. Where IS maintainability is enhanced, organizations can sometimes be better off by sustaining, not decreasing, their overall maintenance efforts.

Testing, as practiced today, is almost exclusively concerned wit h the verification of presently-required function . The purpose o f this note is to focus on future function,i .e . change, and to propos e that the concerns of testing be broadened to include maintainability . What follows is meant to clarify this proposal and to sugges t some maintenance testing methodologies in order to stimulat e research .
