Who did it and when?”?\u0000 If these or other similar statements are familiar, then Software Configuration Management is a subject that should interest you. Software Configuration Management (SCM) is a management method that establishes a discipline for the software development process and provides visibility to that process.\u0000 The step by step procedures used by a large software organization to resolve some of their development problems will be followed here. The result of their efforts was the formulation of a management method that significantly improved the quality of their software products and reduced the costs. It was learned later that other software organizations had gone through similar processes and arrived at similar results. This new tool is now known as Software Configuration Management.","PeriodicalId":262059,"journal":{"name":"Measurement and evaluation of software quality","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129816558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mocatta, a N.Y. based bullion dealer, is a firm which uses its Data Processing to provide both front office (trading) flexibility and back-office capacity to handle large volume days. The business is characterized by the constant trade-off of time against money. Corporate philosophy is to spend money to react quickly rather than to react slowly but perhaps at lower costs.\u0000 The life cycle of a system in this environment normally begins with a marketing report reflecting a new market nitch which the firm can take advantage of. Data Processing is involved almost from the inception of the idea to provide an indication of what existing systems can do for this new opportunity. Because of the nature of the business, each new product offered is usually so unique as to make it impossible for existing systems to support a new product from a trading point of view. Back-office applications are somewhat more common across products, so existing systems can usually provide some support. The key point is that all we really know is that we want to market the new product. Some idea of the time frame in which the product is to be offered is also obtained. The exact workings of defining the product and determining the parameters under which it will be traded usually remain to be worked out prior to the offering date. This therefore means that we have, at the point of commitment, the necessity for evolving data processing support in the same time frame in which the definition is evolving about what it is that we are to support.","PeriodicalId":262059,"journal":{"name":"Measurement and evaluation of software quality","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132819714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, only a single experience with coding while designing will convince any incipient software engineer that a controlled process is needed from the time of system concept though the last maintenance phase. Software Configuration Management has become almost a religion, and EDP auditors have even encountered a few systems that appear to have been specified, then designed, then implemented, then tested, and finally installed—all before maintenance and redefinition occurred. Perhaps the millennium has finally arrived, and software people will soon live in a controlled world with rational practices.\u0000 If you are tempted to believe the foregoing prediction, read the latest issue of FORTUNE, the WALL STREET JOURNAL, or COMMERCE BUSINESS DAILY and note a few problems that may divert us from the path to Nirvana. Data Processing supports commercial, educational, industrial, and governmental activities that are frequently (and repeatedly) redirected. Under circumstances of a largely random environment with thorough business planning a rarity, a critical support activity can expect to be redirected frequently. New ideas will be sliced into partly-completely DP projects, and users “analytical analyses” will become DP systems as if by magic.","PeriodicalId":262059,"journal":{"name":"Measurement and evaluation of software quality","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131302338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The three complexity metrics used were Halstead's effort, McCabe's cyclomatic complexity and Henry and Kafura's information flow complexity. The common software system was the UNIX operating system.
