need of linear process model::
Software requirements analysis. The requirements gathering process is strengthened and focused specifically on software. To understand the nature of the program (s) to be built, the software engineer ("analyst"), the information domain for the software, as well as required function, behavior, performance and interface means . Requirements for both the system and software are documented and reviewed with the customer.
Design. Software design is a multi-process Actually It focuses on four different attributes of a program: data structure, software architecture, interface representations, and procedural (algorithmic) detail. The design process translates requirements into a representation of the software quality assessments for encoding start. Like requirements, the design documented and become part of the software configuration. Code Generation. The design must be translated into a machine-readable form. The code generation step Perform this task. If design is performed in a detailed Sage, code generation can be mechanistically achieved.
Test. Once code is generated, program testing begins. The testing process focuses on the logical operation of the software, ensuring that all settings tested, and the functional internal and external, that is, conducting tests errors uncovered and ensure defined input will produce actual results that agree with expected results.
Support. Software will definitely undergo change once it is delivered to the client (a possible exception is embedded software). Change will occur because I encountered errors because the software must be adapted to changes in the external environment (eg, due to a change needed a new operating system or peripheral), or because the customer requires functional or performance improvements to accommodate. Software support / maintenance reapplies each of the preceding phases of an existing program rather than a new one..
