Software maintenance is the modification of software after delivery. Software maintenance is often considered lower skilled and less rewarding than new development. As such, it is a common target for outsourcing or offshoring. Usually, the team developing the software is different from those who will be maintaining it.
Maintainability is the ease of maintaining or providing maintenance for a functioning product or service. Depending on the field, it can have slightly different meanings. Depending on the field, it can have slightly different meanings.
In software architecture, these attributed are known as "architectural characteristic" or non-functional requirements. Note that it's software architects' responsibility to match these attributes with business requirements and user requirements. Note that synchronous communication between software architectural components, entangles them and ...
In engineering, reliability, availability, maintainability and safety (RAMS) [1] [2] is used to characterize a product or system: 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
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 the robustness of their mainframe computers.
An attribute is an entity which can be verified or measured in the software product. Attributes are not defined in the standard, as they vary between different software products. Software product is defined in a broad sense: it encompasses executables, source code, architecture descriptions, and so on.
In systems engineering, dependability is a measure of a system's availability, reliability, maintainability, and in some cases, other characteristics such as durability, safety and security. [1] In real-time computing , dependability is the ability to provide services that can be trusted within a time-period. [ 2 ]
LTS applies the tenets of reliability engineering to the software development process and software release life cycle.Long-term support extends the period of software maintenance; it also alters the type and frequency of software updates to reduce the risk, expense, and disruption of software deployment, while promoting the dependability of the software.
