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

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

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
Copyright © 2010 BigLever Software, Inc. 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
Copyright © 2010 BigLever Software, Inc. 16
The BigLever 3-Tiered SPL Methodology
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
• Leveraging industry best practices from SPL successes
Copyright © 2010 BigLever Software, Inc. 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

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 Engineeringwith the DOORS/Gears Bridge
Copyright © 2010 BigLever Software, Inc. 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
