System of systemsSystem 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.

Common problems in SoSLack of flexibility and

predictabilityBad coordination across multiple

projectsBusiness value not delivered in

time

Kanban-based scheduling system (KSS)

Example

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 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.
