aCtivity Sequencing Process for Creating AOA Diagrams Find all of the activities that start at node 1. draw their finish nodes and draw arrows between node l and those finish nodes. Put the activity letter or name and duration estimate on the associated arrow 2. Continuing drawing the network diagram, working from left to right. Look for bursts and merges. Bursts occur when a single node is followed by two or more activities. A merge occurs when two or more nodes precede a single node Project T ime Management

r Activity Sequence ing Process for Creating AOA Diagrams 3. Continue drawing the project network diagram until all activities are included on the diagram that have dependencies 4. As a rule of thumb, all arrowheads should face toward the right, and no arrows should cross on an AOA network diagram Project T ime Management

r Activity Sequence ing Task Dependency types Microsoft Projecl Help Iopics Options Back Map Task dependencies The nature of the dependencies between linked tasks You link tasks by defining a dependency between their finish and start dates For example the "Contact caterers"task must finish before the start of the"Determine menus"task. There are four kinds of task dependencies in Microsoft Project Task dependency Example Description Finish-to-start (FS) Task(B)cannot start until task (A) finishes Start-to-start(SS) 匚A Task (B)cannot start until task (A) starts Finish-to- finish(FF) A Task( B)cannot finish until task (A) B finishes Start-to-finish(SF) Task(B)cannot finish until task (A) starts Project T ime Management 15
