Integration is…

Unavoidable – there is always an integrator
Starts late, ends very late
Always full of surprises
Sometimes is on the verge of chaos
Frequently “saved by a hero”

Diverse Integration Processes
• Planned (Company Procedures and Standards)• Tailored for specific projects• Ad-hoc (Manage it as it goes)
Diverse organizational structures
• Professional integration teams• Ad-hoc teams lead by professional integrator• Ad-hoc team led by discipline specialist or subsystem engineer
Diverse Engineering Approaches
• Classics: Functional and Structural• By user feature• By specialty discipline
More than just tests…

Level 1: Product Adaptation
• Co-evolution of the product and the stakeholders’ requirements• Evolution of prototypes through integration and tests
Level 2: System Adaptation
• Operators adapt to the system• Operators’ dissatisfaction causes changes in systems
Level 3: Business Adaptation
• Systems are deployed as assets of the acquiring organization• The assets are combined in creative ways to perform missions• New types of missions change the operational processes

Model-based Systems Engineering
• Integrate models (in vitro) not parts (in vivo)• Integrate earlier• Model system users and business processes
Iterative development
• Find and fix problems fast• Cover all three levels of integration
There is still a need for “creative integrator”

Use different sources of information
Use different types of tests
Use different styles of reporting
Use different types of modeling
Networking

Build ad-hoc teams
Mobilize cooperation of users
Mobilize cooperation of developers
Facilitate information exchange
Adaptation
Systems Integration / The Complexity of Systems Integration/March 2011.16
Adapt reporting to different purposes
Adapt integration approaches
Never stop to learn
Adjust levels of detail and abstraction
Move across levels of integration
Conclusions
Systems Integration / The Complexity of Systems Integration/March 2011. 17
Integration process is complex adaptive system
The human side of integration is generally overlooked
There is a need for creativity in integration
Creative Integrators have to be complex and adaptive
