  1. Systems and Software Product Line Engineering • Charles W. Krueger, PhD • CEO, BigLever Software • www.biglever.com • ckrueger@biglever.com • INCOSE Chicagoland Chapter • Oct 21, 2010

  2. Agenda • Systems and Software Product Lines (SPL) • BigLever Software Gears SPL Framework and Methodology • Gears Demo

  3. BigLever at a Glance • Industry leader in Systems and Software Product Line engineering tools and services • 9 years of commercial practice with GearsTM technology and methods • Strategic partner of IBM Rational • Proven success • BigLever customer case studies illustrate successful transitions • SPL Hall of Fame: Salion (2004), LSI Logic (2006), HomeAway (2009) • Large-scale deployments: Lockheed Martin, General Dynamics, GM, ... • Best ROI metrics in the industry

  4. Systems and Software Product Lines • The key to business success depends on the infusion of new ideas about how products and systems are brought to market • To achieve this goal, today's product development organizations must deliver a product line • A portfolio of similar products or systems with variations in features and functions • Not just an individual product or system

  5. Product Lines and Profitability • Companies need economy of scale in their product lines • In manufacturing, greater profitability is achieved by investing in an efficient means of production – manufacturing infrastructure and shared product assets – that can be used to deploy different “flavors” of a product • As product differentiation and innovation move from the physical attributes to software-based features, the need for an efficient means of production for systems and software product lines has become universal

  6. An Efficient Means of Production for Systems and Software Product Lines

  7. Overview ofSystems and Software Product Line Engineering and Delivery

  8. Systems and Software Product Line Engineering and Delivery • Systems and software product line (SPL) engineering and delivery has emerged as a new approach that • provides an efficient means of production for systems and software product lines • supports the full product line development and delivery lifecycle

  9. Order N2 Complexity Complexity of Product-centric Thinking Impedes Portfolio Production “Vertical” Product Perspective

  10. Processes, tools and techniques cannot overcome the exponential complexity A new approach is required... Engineering Complexity Time The Challenge of Product Line Engineering: Harnessing Complexity Engineering Capability

  11. Shift in Perspective: Efficient Means of Production

  12. Shift in Perspective: Efficient Means of Production

  13. Benefits of a Software Production Line • Economy of Scale from Automated Production • Increase in the scope of product diversity • Increase in the scale of different products effectively delivered and maintained • Cost Savings from Efficiency and Productivity • Increase in productivity and efficiency • Reduction in per-product development cost and overhead • Higher profit margins • Faster Profits from Faster Time to Market • Reduction in time-to-market for new and updated products • Increased agility to react to new opportunities and changing market conditions • Better Products from Better Quality • Increase in customer-perceived product quality • Reduction in defect density • Improved risk management

  14. 2nd Generation SPL Approach

  15. Multiple Dimensions in a 2G SPL Solution • Synchronous concerns: multi-product, multi-phase, multi-baseline • Multi-product. Feature-based variation management and automated production line • Multi-phase. Product line lifecycle assets, architecture and traceability • Multi-baseline. Product line change management and baseline management

  16. Simplify. SPL Asset Focused Development Leverage. Feature Based SPL Management Consolidate. Variation Management & Automated Production • Business-wide management of portfolio by features rather than by products leads to optimized: • Scalability • Time-to-Market • Eliminating duplication, divergence, merging, manual variation techniques, lifecycle silos, and manual production leads to optimized: • Productivity and Cost • High levels of reuse, deep asset expertise, stable organization structure leads to optimized: • Quality The BigLever 3-Tiered SPL Methodology • Leveraging industry best practices from SPL successes

  17. Minimally Invasive Transitions to SPL Practice • Start with what you’ve got • Use an incremental transition strategy • Create a pilot as the catalyst for change • Stage transition to be non-disruptive to production schedules

  22. SPL Source Code & File-based Asset Engineeringwith the Universal Configuration Management Bridge

  23. Early Generation SPL Source Code & File-based Asset Engineering • Early generation product-centric approaches lead to exponential complexity • Clone-and-own and branching • For each new product, make a copy or branch, then modify • Leads to expensive duplication, divergence and merging • Compiler preprocessor directives • Tag source code blocks with #ifdef directives • Leads to complex and convoluted source code and build system • One-size-fits-all with runtime conditionals and startup configuration files • Write the portfolio variations and diversity directly into the source code text • Leads to ever-growing, increasingly complex and convoluted source code

  28. SPL Requirements Engineeringwith the DOORS/Gears Bridge

  29. Early Generation SPLRequirements Engineering for Product Lines • Early generation product-centric approaches lead to exponential complexity • Clone-and-own (and requirements branching) • For each new product, make a copy of requirements and modify • Optionally add links to track commonality and variations • Leads to expensive duplication, divergence and merging • Attributes, links, scripting • Tag each requirement with one or more attributes about product diversity • Leads to high overhead • Major effort to define and implement attributes, dictionaries, semantics, schemas, scripts and filters • Labor intensive to revisit all requirements and attributes during maintenance and portfolio extension • One-size-fits-all • Write the portfolio variations and diversity directly into the requirements text • Leads to complexity and errors interpreting requirements for any particular product
