Business Imperatives
Traditional product development process requires design, analysis, and testing that are time consuming, expensive, with sluggish response to changes in market conditions and technology demands.
Iterative analysis and testing are often the main vehicle for product development, proof of concept and business campaigns.
While maintaining evolutionary technology, a revolutionary approach is required to streamline design, analysis, innovation and product development to meet affordability requirements of business challenges.
Industry is moving ahead with virtual product development and marketing.
Due to use of variety of tools and processes, development of an open-architecture virtual prototyping capability is essential in the context of Model Based Engineering for agile product development, operational excellence, affordability and sustainment.

Virtual Prototyping
Virtual design and prototyping • Is an associative process of design, analysis,
performance evaluation, and visualization in a virtual environment based on mechanistic physical principles, accurate analysis, and reliable performance predictions
• Streamlines design, analysis, innovation, and product development to meet the affordability requirements dictated by the current and future business environment.

Technology Maturity & Product Development
A best practice used in the commercial world and identified by GAO is to separate technology maturation from product development.
In an ideal case, a research organization matures developing
technologies in a laboratory environment.
In a laboratory risk of failure is acceptable. The lab conducts experiments and naturally experiences some failures along the high road to knowledge.
A product developer will use a specific new technology only after it has
achieved a reasonable level of maturity in the research environment.
Use only mature technologies when developing products.

Traditional Versus Agile Project Management
Traditional PM Agile PM
Focuses on processes and tools Focuses on team communication and interaction
Anticipates limited changes and requires comprehensive documentation
Places priority on developing products and/or solutions that will be progressively modified and improved
Emphasizes the importance of contract negotiation and tasks delineated in the contract
Emphasizes the importance of customer — project team collaboration and daily communication
Works the plan; follows the plan to the end
Features flexibility and response to change
No restriction Favors object-oriented technology

Traditional Versus Agile Process Traditional Agile
Fundamental Assumptions
Systems are fully specifiable, predictable, and can be built through meticulous and extensive planning.
High-quality, adaptive products can be developed by small teams using the principles of continuous design improvement and testing based on rapid feedback and change.
Control Process-centric People-centric
Management Style Command-and-control Leadership-and-collaboration
Knowledge Management Explicit Tacit
Role Assignment Individual — favors specialization Self-organizing teams — encourages role interchangeability
Communication Formal Informal
Customer’s Role Important Critical
Project Cycle Guided by tasks or activities Guided by product features
Development Model
Life cycle model (Waterfall, Spiral, or some variation)
The evolutionary-delivery model
Desired Organizational Form/Structure
Mechanistic (bureaucratic with high formalization)
Organic (flexible and participative encouraging cooperative social action)
Technology No restriction Favors object-oriented technology
