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

Software Crisis Software crisis was a term used in the early days of computing science. The term was used to describe the impact of rapid increases in computer power and the complexity of the problems which could be tackled. In essence‚ it refers to the difficulty of writing correct‚ understandable‚ and verifiable computer programs. The roots of the software crisis are complexity‚ expectations‚ and change. The major cause of the software crisis is that the machines have become several orders

Application Software John Hassler Professor C. Mason Computer Information systems 204 September 13‚ 1996 Computer systems contain both hard and software. Hardware is any tangible item in a computer system‚ like the system unit‚ keyboard‚ or printer. Software‚ or a computer program‚ is the set of instruction that direct the computer to perform a task. Software falls into one of two categories: system software and application software. System software controls the operation of the computer hardware;

SOFTWARE TESTING Q4. (a) Is functional testing sufficient to determine code coverage? Answer: No‚ functional testing is not sufficient to determine code coverage. In testing when we refer to code coverage we are talking about how much of the code is being covered/executed/tested during test execution. So the goal behind code coverage is to determine areas that are not being tested and creating tests that can cover these gaps. Structural and functional testing can be used to determine

Software Metric Software metric is a measure of some property of a piece of software or its specifications. Since quantitative measurements are essential in all sciences‚ there is a continuous effort by computer science practitioners and theoreticians to bring similar approaches to software development. The goal is obtaining objective‚ reproducible and quantifiable measurements‚ which may have numerous valuable applications in schedule and budget planning‚ cost estimation‚ quality assurance testing

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
