Stages Of Software Development

Design software called the development, design, maintenance and documentation of software. At the same time apply a variety of technology areas such as informatics, design, subject area, project management, management of digital content and interface design. In the process of software design to define and implement the mandatory inspection characteristics of the program. Test software to test characteristics such as reliability, functionality, usability, availability and portability. The program must meet all requirements, from design to technical nuances. In designing the software and of no small importance are the properties directly in the design process, these include the duration of development and emerging process risks. Software development process is divided into three stages: Stage One: preparation of technical project. Software development can be compared with the construction of the house.

Neither house is not built without design. Start developing software bypassing the stage of a detailed specification is unthinkable. And to make a good technical job to analyze the business processes around the company, its the need for automation, to explore the IT infrastructure and software used. What is described in the specification? It described in detail all the functions to be performed by a program wishes customer of the software, plus technical information database structure, the structure of window applications, the logic of action programs, etc. Draw up terms of reference – it is quite difficult and responsible task to perform that only by a professional programmer.

Terms of reference to time is 5 to 30 business days (perhaps more). When TOR is made, we can already imagine the amount of work, cost and deadlines. Stage Two: programming and testing software. Once the requirements specification and the signing of the development, start programming. At this stage, involve not only specialists in programming, but both managers and designers. Finally, each product must be tested. This allows us to identify and correct errors. Phase Three: Implementation of software and technical support. After development of the program if it complies with the terms of reference, are starting to adopt software developed in the acting business. At this stage the errors found in the work usually easily corrected.
