Software is driving innovation
and enabling customization

 Customers are demanding high-quality tailored solutions
 Pressure to establish a strategic “re-use” strategy
 Need to adhere to safety standards, compliance and regulations
 Trend toward mass customization - shorter product lifecycles
 Need to align business goals with technology capabilities

While introducing Complexity
that few are prepared to handle

More Complex Than a Fighter Jet: Safety regulations and consumer demand for performance
and convenience have led to an exponential spike in cars’ software complexity.
source, HBR, June 2010



Companies must reevaluate traditional
business models and product development processes



And understand the convergence
of business goals and engineering capabilities

The need to innovate intelligently with less

An iterative process



IBM is helping to address the complexity challenge
with two approaches

Variant Management via Strategic Re-use:

Variant management approach that enables companies to
strategically reuse systems and software assets within a
development domain – starting with an “entry point”.

Product Line Engineering:

New generation lifecycle approach that enables the shift from asset
reuse to asset sharing – across an entire product line portfolio and
throughout each stage of the lifecycle. Enables feature-based
product line engineering and automated production for delivering a
complex portfolio of products, with less time and cost.

Product and Portfolio Management
Focal Point



Product and Portfolio Management Approach

• Not develop what • Minimize missed
not wanted – do market opportunity
right thing right

• Process • Align engineering • Leverage
integrate capability with biz social media
change/defect/ objectives – vice/versa
• Supply chain

Manage & Innovative feedback

• Re-evaluate Change Ways to • Customer

• Develop method to Understand Evaluate

• Financial/enterprise
• Expose “how” • ROI/portfolio

• Allows for • Trade-analysis
accountability and weighting
and process
transparency



Requirements Engineering Approach

• Simplify complexity –
• Design reusable variation

• Tracelinks,
• Trace variation trace-
• Visualize system and modules
to test plan and
variation points
back to
products • Understand trace

Change and Configuration Management Approach
Introducing Collaboration, Workflows and Reporting
• Apply same defect

• Same issue can
affect multiple
products
• Focus on • Diff streams for

Quality Management Approach
Requirements-Driven Test

• Each feature (with
all of its variants)

• Core features

line unique variants)

• Product
