How to get Software Requirements right Abstract The importance of getting the software requirement right has made big difference to so many major projects in the IT industry. Many techniques and solutions have been developed for understanding and getting software requirements right first time in the software development life cycle‚ but fewer people are taking these techniques into account and this is the reason why most of the IT projects are failing. I define here how to get software requirements

in the development of the project. It is referred to as the “waterfall model with overlapping phases” or “the waterfall model with feedback”. The phases are the same as the pure waterfall model‚ but is done in discontinuous basis. This enables the phases to overlap and provide feedback between phases. The figure below shows how the phases overlap each other. Software Concept Requirements Gathering and Analysis Design and Architecture Development and Coding System Testing Software Concept

Determining Operating Systems and Software Applications BIS/320 Amazon has made a business of selling a variety media types while also making the reselling of the same media an attractive option. What better way to regain in part what you spent on media interests than to resell it and have money to put towards the next interest. As of 2004 Amazon began running the Linux operating system across the board. Amazon then became one of the largest and well known companies running the Linux

Combining various models. ◦ Prototyping ◦ Linear Sequential Model/Waterfall model Iterative and Incremental Development is at the heart of a cyclic software development process developed in response to the weaknesses of the waterfall model. It starts with an initial planning and ends with deployment with the cyclic interactions in between. SPIRAL MODEL Liaison/Customer Communication
