4 Introducing dependability reviews
4.1 General
Dependability reviews are key activities in the dependability plan. The persons in charge of dependability reviews have the responsibility for ensuring that dependability reviews are carried Out during the life cycle.
Reviews involve investigating the current situation in order to compare it with what is expected or required. Reviews identify discrepancies, risks and potential problems, analyse them and recommend improvements.
Dependability reviews comprise a coherent set of reviews for different aspects of dependability. These reviews are performed repeatedly throughout the life cycle, continually providing follow- up actions and assessment of their effectiveness.
Dependability reviews can be performed from various perspectives, such as:
— the dependability attributes of an item including reliability, maintainability, supportability and availability;
— other time related characteristics of an item such as durability and recoverability:
— dependability related functions such as safety and security:
— cost efficiency, including both life cycle cost and the short term cost;
— activities carried out to achieve or assess dependability outcomes:
— effectiveness of dependability processes;
— accountability of, and to, various stakeholders for potential failures;
— adaptation to changes in requirements, environments, objectives and/or purpose of the system.
A dependability review provides assurance that dependability is achieved throughout the life cycle either by demonstrating that requirements are met or by identifying problems and making improvements. A dependability review can be used to provide evidence that a dependability claim is satisfied as part of a dependability case (IEC 62741 (3J1 gives guidance on the content of a dependability case and establishes general principles for its preparation).
Systematic dependability reviews across the system life cycle enable agile corrective redirection of effort with less waste. This is particularly beneficial given the current trends for increasing system complexity, tightening development time and prolonged operational life.
Some environments or conditions for the trends include:
— ubiquitous network connection to any range of systems controlled by others;
— frequent changes in the system’s context such as user expectation and competitions in the market:
— inability to discard the old and start anew due to, for example cost consideration and preferences for circular econOmy”.
Dependability reviews help identify, predict and correct problems as they arise in the system life cycle while they are small enough to be addressed.IEC 62960 pdf free download.
