  1. Agile concepts in System of Systems engineeringAlexey Tregubov

  2. Outline • What is a System of Systems (SoS)? • Common problems in SoS • Kanban-based scheduling system for SoS • Comparison with ICSM

  3. System of systems • System of systems is a collection of systems that together to create a new, more complex system which offers more functionality and performance than simply the sum of the constituent systems.

  4. System of systems around us: • SoSs within Our Homes • Enterprise-wide SoS: • Regional Area Crisis Response SoS • National and International Defense SoS

  5. System of systems: example

  6. System of systems: example

  7. Common problems in SoS • Lack of flexibility and predictability • Bad coordination across multiple projects • Business value not delivered in time

  8. Kanban-based scheduling system (KSS)

  9. KSS

  10. Example

  11. Priority calculation • Priority calculation based on the following: • Business value • Class of service (eg. Standard, Important, Date Certain, Critical Expedite) • Estimated effort • Specialties required

  12. Simulation model • Static model: • Describes objects (work items, backlogs, resources) and their relationships. • Dynamic model: • Describes how work items’ dependencies change over time. This includes establishing relationships with new or existing dependent task and breaking down the task into a set of subtasks. • Apply scheduling/prioritization algorithms.

  13. Comparison with ICSM • Value based engineering approach • Incremental commitment • Coordinate multiple levels of systems engineering activity
