- Best ROI metrics in the industry


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 ofSystems 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

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

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


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 Engineeringwith 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 Engineeringwith the DOORS/Gears Bridge


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


- 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

• Dual Plugin “Bridge” between DOORS and Gears SPL Framework- Gears plugin extensions

• Automated configuration of DOORS requirements, based on Gears feature profiles

SPL Model-driven Developmentwith the Rhapsody/Gears Bridge

• Early generation product-centric approaches lead to exponential complexity- Clone-and-own

• For each new product, make a copy of a similar model and modify


- One-size-fits-all

• For each new product, add product diversity meta-logic in one model

• Leads to large and complex models with product diversity logic intermingled with application logic
