Outline
  • What is a System of Systems (SoS)?
  • Common problems in SoS
  • Kanban-based scheduling system for SoS
  • Comparison with ICSM
system of systems
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.
system of systems around us
System of systems around us:
  • SoSs within Our Homes
  • Enterprise-wide SoS:
  • Regional Area Crisis Response SoS
  • National and International Defense SoS
common problems in sos
Common problems in SoS
  • Lack of flexibility and predictability
  • Bad coordination across multiple projects
  • Business value not delivered in time
priority calculation
Priority calculation
  • Priority calculation based on the following:
    • Business value
    • Class of service (eg. Standard, Important, Date Certain, Critical Expedite)
    • Estimated effort
    • Specialties required
simulation model
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.

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