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

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

An Efficient Means of Production for Systems and Software Product Lines

Overview of Systems and Software Product Line Engineering and Delivery

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

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

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

Shift in Perspective: Efficient Means of Production

Shift in Perspective: Efficient Means of Production

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

2nd Generation SPL Approach

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

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

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

SPL Source Code & File-based Asset Engineering with the Universal Configuration Management Bridge

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

SPL Requirements Engineering with the DOORS/Gears Bridge

Early Generation SPL Requirements 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
