Rhapsody/Gears Bridge 2.3

Tab navigation

While Model-Driven Development™ (MDD) technology provides a powerful enabler for the rapid development of individual products within a product line, as well as greater conceptual clarity for the maintenance and evolution of those products over time, companies face complex challenges in managing product diversity across a product line. Product line engineering (PLE) methods and tools are specifically designed to provide these essential capabilities. The Rhapsody/Gears Bridge provides a simple, elegant approach to effectively manage product line diversity in MDD and to cleanly integrate MDD into PLE lifecycles.

Integrated MDD and PLE Capabilities

With the Bridge solution, you can utilize: 1) Rhapsody MDD models as first-class reusable assets in the Gears PLE portfolio development framework, and 2) Gears PLE constructs as first-class software engineering mechanisms for managing product line diversity in Rhapsody MDD models. More specifically, the Rhapsody/Gears Bridge allows you to:

  • Use PLE mechanisms to manage the diversity for a full product line portfolio in a single, consolidated MDD model.
  • Automatically configure different Rhapsody model behaviors for different products, simply by making product feature choices in a Gears feature profile.
  • Convert Rhapsody model elements into Gears variation points to encapsulate the PLE diversity. Perform integrated PLE operations directly from Rhapsody menus.

  • + Business problem

    The complexity of developing a software product line – a portfolio of similar products with variations in features and functions – poses exponentially complex development challenges, due to intertwined feature variations dispersed across multiple products on different production schedules.

    These challenges are large enough to inhibit a company's ability to hit strategic market windows and expand the scale and scope of a product line portfolio.

  • + Return on investment

    BigLever’s Gears solutions offer proven ROI, large enough to impact the fundamentals of how companies compete:

    Variation management and automated production lead to optimized software reuse, increased productivity and reduced cost.

    • LSI Logic increased productivity by 325%
    • Salion lowered development costs by 75%

    SPLE asset focused engineering leads to maximum software reuse, deep asset expertise and optimized product quality.

    Salion reduced defect rates by 78%

    Feature-based product line evolution leads to optimized time-to-market and portfolio scalability. Salion reduced time-to-market by 65%, LSI Logic scaled portfolio 550% in 2 years

  • + Competitive advantage

    Conventional approaches lead to complexity and inefficiency:



    • For each new product, copy a similar model and modify
    • Leads to expensive duplication, divergence and merging




    • For each new product, extend one model with meta-logic for new diversity
    • Leads to complex model with diversity logic intermingled with application logic


    The Rhapsody/Gears Bridge offers significant competitive advantage through the synergistic simplifications offered by MDD and PLE:

    Configurable model behavior


    • Enables configurable diversity in model behaviors
    • No need for one-size-fits-all


    One consolidated and reusable MDD model


    • Enables automated PLE configuration from a consolidated MDD product line model
    • No need for clone-and-own
