Reliability, availability and serviceability. Reliability, availability and serviceability (RAS), also known as reliability, availability, and maintainability (RAM), is a computer hardware engineering term involving reliability engineering, high availability, and serviceability design. The phrase was originally used by IBM as a term to describe ...
Serviceability: Serviceability is the speed with which the product can be put into service when it breaks down, as well as the competence and the behavior of the service person. Aesthetics : This is the usual appeal of the product, often taking into account factors such as style, colour,packing alternative and other sensory features. i.e.Those ...
Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, OR will operate in a defined environment without failure. [1]
Serviceability engineering may also incorporate some routine system maintenance related features (see: Operations, Administration and Maintenance (OA&M.)) A service tool is defined as a facility or feature, closely tied to a product, that provides capabilities and data so as to service (analyze, monitor, debug, repair, etc.) that product.
All action taken to retain material in a serviceable condition or to restore it to serviceability. It includes inspections, testing, servicing, classification as to serviceability, repair, rebuilding, and reclamation. [5] All supply and repair action taken to keep a force in condition to carry out its mission.
Reliability: Ability to perform a specific function and may be given as design reliability or operational reliability. Availability: Ability to keep a functioning state in the given environment. Maintainability: Ability to be timely and easily maintained (including servicing, inspection and check, repair and/or modification) Safety: Ability not ...
Engineering. In engineering, maintainability is the ease with which a product can be maintained to: cope with a changing environment. In some cases, maintainability involves a system of continuous improvement - learning from the past to improve the ability to maintain systems, or improve the reliability of systems based on maintenance experience.
Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements. Agility in working software is an aggregation of seven architecturally sensitive attributes: debuggability, extensibility, portability, scalability, securability, testability and understandability.
