Agile • Agile isnot • Methodology • Specific way of developing software • Framework or process • So what is Agile • Agile is set of values and principles. • Can be seen as beliefs that team can use to make a decisions about how to do the work of developing a software. Abdalmajid Abdalla 115/25/2020
- 12. Agile Manifesto • “Weare uncovering better ways of developing software by doing it and helping others do it, Through this work we have come to value: • Individuals and interactions over processes and tools • Working software over comprehensive documentation • Customer collaboration over contract negotiation • Responding to change over following a plan • That is, while there is value in the items on the right, we value the items on the left more.” Abdalmajid Abdalla 125/25/2020
- 13. Principles behind theAgile Manifesto • We follow these principles: • Our highest priority is to satisfy the customer through early and continuous delivery of valuable software. • Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage. • Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale. • Business people and developers must work together daily throughout the project. • Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done. Abdalmajid Abdalla 135/25/2020
- 14. Principles behind theAgile Manifesto… • The most efficient and effective method of conveying information to and within a development team is face-to-face conversation. • Working software is the primary measure of progress. • Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely. • Continuous attention to technical excellence and good design enhances agility. • Simplicity--the art of maximizing the amount of work not done--is essential. • The best architectures, requirements, and designs emerge from self- organizing teams. • At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly. Abdalmajid Abdalla 145/25/2020
- 15. Examples • If weare in a case that need requirement from customer? “Sign it” • If developer is working on feature, then needed a database? “Full or just what he need” • The Idea is making decisions based on Values and Principles that the team decide to follow. • We have to put in our mind to not mimic others to be Agile, because by following Values and Principles team will make practices and the practice may change with the time.
