The Software Crisis • The most visible symptoms of the software crisis are o Late delivery‚ over budget o Product does not meet specified requirements o Inadequate documentation • Some observations on the software crisis o “A malady that has carried on this long must be called normal” (Booch‚ p. 8) o Software system requirements are moving targets o There may not be enough good developers around to create all the new software that users need o A significant portion of developers’ time must often

2. Approach to Systems Development. The standard process followed in an organisation to conduct all these steps necessary to analyse‚ design‚ implement and maintain information systems is called system development. There are two different Systems Development approach System Development Life Cycle (SDLC). Agile Development. System Development Life Cycle (SDLC) The SDLC is used to describe the process and methodology for developing and maintaining the software. The SDLC is also including

Custom software (also known as bespoke software) is software that is specially developed for some specific organization or other user. As such‚ it can be contrasted with the use of software packages developed for the mass market‚ such as commercial off-the-shelf (COTS) software‚ or existing free software. Custom software can be developed by an in-house software development group‚ or be commissioned from a software house or independent software developer. Since custom software is developed for

Evolution of Software The Early Years (50’s – 60’s) * This generation was characterized by Batch orientation‚ limited distribution‚ and customization of software. * In Batch Processing‚ the system handles an entire sequence of jobs together‚ often with little or no human intervention. * Also‚ as computers were not widely used at that time‚ only in scientific and military institutions‚ software could be highly customized since distribution was limited. Job mobility was low‚ and the

4 Metrics for Software Quality Software quality metrics are a subset of software metrics that focus on the quality aspects of the product‚ process‚ and project. In general‚ software quality metrics are more closely associated with process and product metrics than with project metrics. Nonetheless‚ the project parameters such as the number of developers and their skill levels‚ the schedule‚ the size‚ and the organization structure certainly affect the quality of the product. Software quality metrics
