a sequential design process‚ often used in software development processes‚ in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of Conception‚ Initiation‚ Analysis‚ Design‚Construction‚ Testing and Maintenance. The waterfall development model originates in the manufacturing and constructionindustries; highly structured physical environments in which after-the-fact changes are prohibitively costly‚ if not impossible. Since no formal software developmentmethodologies existed

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

and develop applications. 2. Why is software quality important to security? What specific steps can an organization take to ensure software quality? Software errors pose a constant threat to information systems‚ causing untold losses in productivity. Growing complexity and size of software programs‚ coupled with demands for timely delivery to markets‚ have contributed to an increase in software flaws or vulnerabilities. A major problem with software is the presence of hidden bugs or program
