Lecture Software engineering - Chapter 3: Agile development

Chapter summary: Agile software engineering represents a reasonable compromise between to conventional software engineering for certain classes of software and certain types of software projects; agile development processes can deliver successful systems quickly; agile development stresses continuous communication and collaboration among developers and customers;. | Chapter 3 Agile Development Slide Set to accompany Software Engineering: A Practitioner’s Approach, 7/e by Roger S.

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.” Kent Beck et al What is “Agility”? Effective (rapid and adaptive) response to change Effective communication among all stakeholders Drawing the customer onto the team Organizing a team so that it is in control of the work performed Yielding Rapid, incremental delivery of software Agility and the Cost of Change An Agile Process Is driven by customer descriptions of what is required (scenarios) Recognizes that plans are short-lived Develops software iteratively with a heavy emphasis on construction activities Delivers multiple ‘software increments’ Adapts as changes occur Agility Principles - I 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. Agile processes harness change for the customer's competitive advantage. 3. Deliver working software frequently, from a couple of weeks to a couple of months, with a .
