(stakeholder) ownership. The Systems Life Cycle (SLC) is a methodology used to describe the process for building information systems‚ intended to develop information systems in a very deliberate‚ structured and methodical way In Royce’s original waterfall model‚ the following phases are followed in order: * Requirements specification * Design * Construction (AKA implementation or coding) * Integration * Testing and debugging (AKA Validation) * Installation * Maintenance

Resources to Create Secure Coding Policies and Guidelines SDLC has many models that will be beneficial in creating secure coding polices. These models are: Waterfall Iterative and Agile Scrum Rapid Application Development Rational Unified Process Spiral Model and V-Model There is also principle that should be followed when securing an application.

This business model encourages startups to quickly discover whether their business idea or product is viable by talking to potential customers in the early stages of product development. It makes a switch from traditional waterfall approach of having a big design up front to an iterative agile techniques. It’s a method for creating and sustaining innovations in all types of organization. Ries believes that by creating a product that was tailored to its early customers‚ they

approach to the project management which help to respond to the unpredictability of building software through incremental‚ iterative work cadences‚ known as sprints. This methodology was developed to deal with situation where the waterfall model fails. The biggest drawback of waterfall model is that it assumes that every requirement of the project can be identified before any design or coding occurs. This may always be applicable for the development of a automobile on an assembly line‚ in which each piece

The Rapid Application Development (RAD) approach to software development puts clear emphasis on development and prototyping‚ and less on planning tasks. In RAD‚ prototyping acts as an alternative to design specifications. RAD works well when user interface is given a bigger focus rather than non-graphical user interface programs. RAD refers to a development life cycle designed to make development much faster and produce higher quality systems than traditional life cycle. The key objectives of RAD
