AON Network Characteristics  Construct from left to right  Any activity can have only one start node  No two activity can have the same start and end node  Dummy activities are used in AOA  Start the network by finding those activities that have no predecessors  Calculate activity times using probabilistic or deterministic means TCS2414 Software Engineering Fundamentals,MMU,Cyberjaya 34

Terms  Activity - A task or job which takes time & use up resources  Represented by labeled arrow A  Event - An instantaneous point representing the start or finish of an activity  Represented by node TCS2414 Software Engineering Fundamentals,MMU,Cyberjaya 36 1

Dummy Activity  Represented by dotted arrow  Used when relationships between activities require no work  Applied when  two activities start and end similarly  succeeding activities have partial dependencies on predecessor activities TCS2414 Software Engineering Fundamentals,MMU,Cyberjaya 37

PERT and CPM PERT  R&D Development  Originally focused on time only  Uses probabilistic time estimates  AOA based  Critical path & slack CPM  Construction  Time and Cost  Uses deterministic time estimates  AON based  Critical path & slack  Used in most software TCS2414 Software Engineering Fundamentals,MMU,Cyberjaya 38

Critical Path  By drawing a network diagram, you can figure out the critical path of your project.  The critical path is the longest path through the network. If something falls behind schedule on the critical path, the whole project falls behind schedule unless time is made up elsewhere.
