© 2011 BA ValueBASE LLP “Creation” + “Approach for re-creation”  Approach defines  Who  Does What  When and  How PROCESS “Creation of software” + “Approach for its re-creation”  Approach defines  Who - Role  Does What - Activity  When – Workflow and  How - Guideline SOFTWARE ENGINEERING PROCESS Engineering?

© 2011 BA ValueBASE LLP Requirements Initial Planning Analysis & Design Implementation Deployment Test Evaluation Management Environment Iterative Process Each iteration results in an executable release What?  Based on Barry Boehm’s Spiral Model  Process consists of a sequence of incremental steps, or iterations.  Each iteration has all of the development disciplines (requirements, analysis, design, implementation, etc.)  Each iteration also has a well- defined set of objectives.  Each iteration produces a partial working implementation of the final system.  Successive iteration builds on the work of previous iterations to evolve and refine the system until the final product is complete.

© 2011 BA ValueBASE LLP What is RUP?  It is an  Iterative  Use Case Driven  Architecture Centric Software development process  Defines  9 Disciplines, each with  Detailed Workflow and Activities  Performed by specific Roles  Producing specific Artifacts  4 Phases, each having ‘n’ iterations  RISK based approach Rational Unified Process

© 2011 BA ValueBASE LLP RUP Best Practices  Develop Iteratively  Manage Requirements  Use Component Architecture  Model Visually  Continuously Verify Quality  Manage Change Rational Unified Process

© 2011 BA ValueBASE LLP CONCEPT: BASICS OF AGILE

© 2011 BA ValueBASE LLP Agile Manifesto Definitely Valuable More Valuable

© 2011 BA ValueBASE LLP Guiding Principles behind Agile Manifesto early and continuous delivery of valuable software 1.Our highest priority is to satisfy the customer through early and continuous delivery of valuable software 2.Welcome changing requirements, even late in development 2.Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage 3.Deliver working software frequently shorter timescale 3.Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale 4.Business people and developers must work together daily 4.Business people and developers must work together daily throughout the project 5.Build projects around motivated individuals 5.Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done is face-to-face conversation 6.The most efficient and effective method of conveying information to and within a development team is face-to-face conversation primary measure of progress 7.Working software is the primary measure of progress 8.Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely technical excellence and good design 9.Continuous attention to technical excellence and good design enhances agility 10.Simplicity- 10.Simplicity--the art of maximizing the amount of work not done--is essential from self-organizing teams 11.The best architectures, requirements, and designs emerge from self-organizing teams the team reflects on how to become more effective 12.At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly

© 2011 BA ValueBASE LLP Where does Agile Fit? Agile works well with complicated, complex projects that need to adapt to changes Waterfall works with well defined and unchanging projects
