Boehm and Ross (1989) extended the original spiral model by including considerations related to stakeholders. The win-win spiral model uses the theory W management approach, which requires that for a project to be a success, the system’s key stakeholders must all be winners. The way to achieve this win-win condition is to use the negotiation based approach to define a number of additional steps of the normal spiral development cycle. The additional steps are the following: • Identify next-level stakeholders. • Identify stakeholders’ win conditions. • Reconcile win conditions. • Establish next-level objectives, constraints, and alternatives. • Evaluate product and process alternatives. • Resolve risks. • Define the next-level of product and process, including partitions. • Validate product and process definitions. • Review and commit. The advantages from a win-win spiral model is the collaborative involvement of stakeholders that results in less rework and maintenance, early e

software is a logical rather than a physical system element. Therefore, software has characteristics that are considerably different from those of hardware. Some of the major differences are the following: 1. software is developed or engineered, it is not manufactured. • The concept of raw material is non existent here. It is better visualised as a process,  rather than a product. • The human element is extremely high in software development, compared to manufacturing. • The development productivity is highly uncertain, even with standard products, varying greatly with skill of the developers. • The development tools, techniques, standards, and procedures vary widely across and within an organisation. • Quality problems in software development are very different from those in manufacturing. Whereas the manufacturing quality characteristics can be objectively specified and easily measured, those in the software engineering environment are rather elusive. 2. Software development

During the late 1960s and 1970s, there was an outcry over an impending software crisis. The  symptoms of such a crisis surfaced then and are present even today. The symptoms are the following: 1. Software cost has shown a rising trend, outstripping the hardware cost. Boehm (1976, 1981)  indicated that since the fifties, the percentage of total cost of computation attributable  to hardware has dramatically reduced and that attributable to software has correspondingly  increased. Whereas software cost was only a little over 20% in the 1950’s, it was  nearly 60% in the 1970’s, and about 80% in the 1980’s. Today, the computer system that we  buy as ‘hardware’ has generally cost the vendor about three times as much for the software  as it has for the hardware (Pressman 1992). 2. Software maintenance cost has been rising and has surpassed the development cost. Boehm  (1981) has shown that the bulk of the software cost is due to its maintenance rather than its  development. 3. Software is

We are living in an information society where most people are engaged in activities connected with either producing or collecting data, or or gangling, processing and storing data, and retrieving and disseminating stored information, or using such information for decision making. Great developments have taken place in  computer    hardware technology, but the key to make this technology useful to humans lies with the software technology. In recent years software industry is exhibiting the highest growth rate throughout the world, India being no exception. Software is the general term for information that's recorded onto some kind of medium. For example, when you go to the video store and rent or buy a tape or DVD, what you're really getting is the software that's stored on that tape or disk. Your VCR or DVD player are hardware devices that are capable of reading the software from a tape or disk and projecting it onto your TV screen, in the form of a movie. Your  computer
