  1. Product line introduction in a multi-business line context.An experience report B.J. Pronk Philips Medical Systems ben.pronk@philips.com

  2. Contents • The context, Philips Medical Systems • The product line set-up • Organization • Problems

  4. The product line set-up The approach, a common architecture for a number of products from different business lines Implement everything used by > 2 products in a platform Achieve High reuse percentage (>75%)

  5. The product line set-up • Technical: • Standard PC/PCI infrastructure with industrial PC • Intel 960RP for real time PCB’s • Windows-NT platform for host • C++/MFC as main language • VxWorks/RMX for real time parts • C as main language • (D)COM as interface technique

  6. The product line set-up • Component frameworks as main variation structure • A set of interfaces (provides + requires) • A framework with general functionality • A (variable) set of plug-in components • One platform, reused as a single component • Platform implements all generic functionality • Binary reuse of platform that defines fixed variation points • Each variation point is a component framework • Specific functionality in separate components

  7. The product line set-up

  8. Organization • Set-up according Jacobsson/Griss model • AFE, architecture family engineering: Definition of architecture, generic vs. specific, variation points. • CSE, component system engineering: Implementation of the platform. • ASE, application system engineering: Implementation ofactual products

  9. Organization

  10. Organization • Main problem areas • Subcritical ASE’s • Decision model/responsibilities for platform • Competence struggles/reallocation of responsibilities • Now organized as multi BL projects, introducing a widening scope of products.
