  1. Extreme Programming Frank Bergmann, fraber@fraber.de Barcelona, July 27th, 2001

  2. Content • Problems • Why? • Measures • Extreme Programming • Links

  3. Problems with IT Projects Some Statistics • Only 20% in time and budget • 40% never become operative • Deviations up to 200% normal => Disastrous situation

  4. Why??? • Management lacks comprehension • Greedy providers • „Feature Creep“ • Complexity of IT • Heterogenous systems problem • Fashionable Software Architectures • Tech Mentality • Communication problems between biz and tech guys • Fluctuations in project team • Tech wizards are difficult to deal with • Poor Project Management

  5. Measures (1) • „1001 Methodologies“ • Extreme Programming, • UML, Rational Unified Process, • Capability Maturity Model, • Microsoft Solutions Framework, • ISO 9001/9002 • Estimation and Productivity Models • Function Point Analysis, ... => Don‘t get hooked to a single „religion“. => Get an expert in software engineering or outsource critical projects

  6. Measures (2) • Iterations and frequent releases • Analysis – Development – Deployment flow • User-centered system description (Use-Cases, User stories, ...) • CRC Cards • . . . => Software development is a process just like industrial production. Make sure you adapt the process to your environment.

  7. Exteme Programming Flow
