  3. Agenda • Where are we today? • Challenges in software development (TPF, IT, Embedded, etc.) • What is missing? And how can we resolve the issues? • IBM Software Development Platform • Closing Comments

  4. The Software Development Paradox Industry Truism? Quality Time-to-Market

  5. How Is Business Doing? • Over 30%1 of software projects are cancelled • Of the remaining 70%, many are over budget, over time, or defective functionally • 52%1 of software projects cost 189%1 original estimates • Only 16%1 of are completed on time and within budget • For large enterprises, this can be as bad as 9%1 1 Standish Group

  6. Why are organizations failing? • Hitting the wall before release (1) • Losing/adding team members • Unforeseen technology difficulties • Unforeseen or changing requirements • 90% done (2) • Riskiest features deferred • Endless Q&A (3) • Poor quality code • Bugs found late are very costly • Negative ROI • Failure Traps – Balance and Guidance Required • Prototype • Scripting • 4GL’s Figure-1 Figure-2 Figure-3

  7. Disparate toolslacking required integrations Software Development Obstacles • Environment Complexity • Limited tooling - legacy tools, compilers, integrations • Lack of built-in debugging and testing capabilities • Host Platforms – Linux, UNIX, zSeries • Application Complexity • Legacy systems – difficult to maintain / understand / modernize • Transaction driven – highly unpredictable events and loads • Strong timing constraints – realtime requirements • Concurrent / Distributed / Networked • Process Complexity • No defined development process • Lack of understanding • Hard to maintain • Architectural enforcement or knowledge • Inadequate testing • Poor performance • Unreliable builds • Changing requirements • Missing integration

  8. IBM Software Development Platform Transforming for Success: What is Required? • Good / Complete Planning • Complete Requirements & Specification Definition (end-user signoff) • Requirement Management and Implementation Control (ie., what shall get built and when) • Clear Responsibility and Accountability of Team Members • Individual workflows • Clear communication paths • Schedule Control • Software Configuration Management, Activity, and Test Managenment • Project Statistics • Clear Communication and Validation • Architectural Enforcement • Test Validation and Support

  9. Agenda • Where are we today? • Challenges in software development (TPF, IT, Embedded, etc.) • What is missing? And how can we resolve the issues? • IBM Software Development Platform • Closing Comments
