Agile-overview: Agile Manifesto, Agile principles and Agile Methodologies

  1. 1. Agile - Overview What is Agile, Agile Manifesto, Agile principles and Agile Methodologies Balaji Sathram, PMI-ACP, CSP, CSM. 31st March 2015.
  2. 2. Agenda • What is Agile? • Agile Manifesto • Agile principles • Agile Methodologies 2
  3. 3. What is Agile? • Agile development is an umbrella term that describes several agile methodologies to handle IT teams and projects. The word ‘Agile’ is derived from agile manifesto ( 3
  4. 4. Agile manifesto • In 2001, a group of people got together to discuss about better ways of software development as the traditional approach was failing in reaching customer requirements. After many discussions, they came up with the agile manifesto Image Source: 4
  5. 5. Agile manifesto Continued… • We are uncovering better ways of developing software by doing it and helping others does it. Through this work we have come to value 5
  6. 6. Agile Principles 1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. Unlike the traditional software development (Delivery after months/years of work), small components of the project functionality are delivered within weeks after starting the project. It is incremental delivery rather than a single delivery. Features having high business value getting delivered early and continuously gains customer satisfaction which is very critical in business. 6
  7. 7. 2. Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage. Main objective of the agile software development is to give a competitive edge to customer by implementing evolving requirements at any point of time throughout the project 7
  8. 8. 3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale. Agile development focuses on fast, iterative deliveries than traditional one-time deliveries 8
  9. 9. 4. Business people and developers must work together daily throughout the project. In Agile software development, development team works closely with business people/customers on daily basis and takes their feedback. With this better working relationship is established and development team will correct their mistakes quickly based on customer’s feedback 9
  10. 10. 5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done. Agile software development emphasizes on team culture; concentrates more on factors which build trust in the team. Agile strongly believes that these are the reasons for team’s/software’s success 10
  11. 11. 6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation. Agile development encourages face to face conversations as it is better compared to e-mail/ phone/ communicator. It avoids many mis-understandings and confusions 11
  12. 12. 7. Working software is the primary measure of progress. In Agile development, progress & success is measured by working software (i.e. the component of software which ready to get delivered to customer / delivered to customer) 12
  13. 13. 8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely. Agile development progresses in very consistent; neither slow nor fast. Total team is responsible and accountable for the same 13
  14. 14. 9. Continuous attention to technical excellence and good design enhances agility. We know that agile development focuses on extrinsic quality (customer satisfaction & Product quality) and along with this it takes care of intrinsic quality as well by following best agile development practices 14
  15. 15. 10. Simplicity--the art of maximizing the amount of work not done--is essential. Agile development always keeps software simple, workable and easy to maintain. Traditionally developed software products are complex due to cumbersome design, requirements etc. 15
  16. 16. 11. The best architectures, requirements, and designs emerge from self-organizing teams. Agile development believes that best architectures, requirements, and designs emerge from self-organizing teams as there are no hierarchies involved here. The team is empowered to organize themselves to be more effective and efficient. Transparency, inspect, adapt, Continuous planning, Continuous customer feedback and customer collaboration makes team self-organizing 16
  17. 17. 12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly. In traditional software development approach, team will be waiting till the end of the project to conduct post-project review. But agile software development emphasizes continuous review. Team member can give feedback to team member or to process @ any point of time by writing it in post- it/face to face. Inspecting and adapting continuously solves many of the repetitive issues experienced by many teams and projects. 17
  18. 18. Agile Methodologies • If you assume as Agile as umbrella (as shown in figure), it consists several specific methodologies under its shadow. Broadly agile methodologies are classified in to 2 types 1.Light weight Approaches 2.Fuller Approaches 18
