I have explain many things in this blogs, you must read this . Over the past decade many organisations have adopted the Agile development models for successfully developing software products. Agile Model has various development methodologies which essentially involve iterative and incremental approach to software development. Some key differences between the traditional Waterfall model and the Agile models:
Agile
Waterfall
Allows flexibility in project execution
Follows Structured approach which resists change
Agile model breaks down the overall product Single Sequential process with phases of development into many small projects called Analysis -> Design -> Coding -> Testing Sprints with a working product as output. Each sprint consist of the following development phases of - Analysis - Design - Coding - Testing More Suitable for managing change even at late Less adaptive to changes. Once a phase stages of a project complete, any change affects all the previous phases and seriously impacts time/cost/quality Agile model also requires a collaborative approach which needs continuous engagement with the customer and close interaction among the team members.
Customer interaction is limited to the Requirement gathering and Testing phases. The Team depends on elaborate documentation for interaction.
AGILE MANIFESTO • INDIVIDUALS AND INTERACTIONS over PROCESSES AND TOOLS • WORKING SOFTWARE over COMPREHENSIVE DOCUMENTATION • CUSTOMER COLLABORATION over CONTRACT NEGOTIATION • RESPONDING TO CHANGE over FOLLOWING A PLAN (www.agilemanifesto.org)
Why Agile: 1. Deliver Value Early: the Agile approach delivers features in short sprints which results in working software which can be verified very early in the project lifecycle. This translates to delivering value in each sprint which allows the business to release a working product into the market in a few weeks instead of many months. 2. Accommodate Changes Easily: You can start development of the product based on what the business needs now. If the business needs to evolve or change, these changes can be planned in the future sprints.
In this post, we will focus on SCRUM, which is a popular and widely successful Agile development methodology.
