The demand for added software functionality and faultless softwareproducts has grown as more proce
42、sses are automated to take advantage of the power of the computer. Todaysmodern systems are so complex, that they are unable to perform their functions without software. The use ofcommercially available “off-the-shelf” software products is accelerating as the variety of available products growsand t
43、he rapid evolution of software engineering technology reduces reliance on custom-coded software. Theobject-oriented development approach, which is based on the development of an application system through theextension of existing libraries of self-contained units, has also reduced requirements for c
44、ustom-coded software.This has led to intense focus on concomitant software product quality or self-contained software unit quality.Development of custom software is prone to rework as a result of failure to meet user requirements. The use ofcustom software may also require a larger than anticipated
45、effort with respect to deployment, implementation,training, and maintenance support activities. Acquisition of commercial “off-the-shelf” software products, or, reuseof in-house existing software products, is also not without risk. Problems can be encountered because the “off-the-shelf” software pro
46、ducts may require customizing; testing and analysis requirements may be large; productmaintenance and support is doubtful when the product becomes obsolete or revised; it may be difficult to integratesoftware products into larger systems; and the quality of the product may not be consistent with the
47、 required qualityof the target system.Commercial “off-the-shelf” software products are extremely varied. They can be:Gbe a) used as stand-alone products (i.e., payroll, accounting software, consumer software or shrink-wrappedsoftware i.e., word-processing software, spreadsheets);Gbe b) integrated as
48、 components into a larger system which consists of other software and hardwarecomponents (i.e., operating system, relational data base management system, graphical users interfaceGUI);Gbe c) embedded in hardware (i.e., communication data link, programmable array logic PAL);Gbe d) embedded as part of
49、 a configurable software/hardware system that can be used for the development of aspecific application (i.e., distributed control system);Gbe e) CASE tools used to support the software development and maintenance process (i.e., compilers,configuration management tools).Errors in stand-alone software products can impact productivity, cause financial loss, or cause unnecessary rework.Software components can be difficult to integrate, affect the reliability of the overall system, or be incompatible withsystem obje
