Event chain diagrams are visualizations that show the relationships between events and tasks and how the events affect each other. Event chain diagrams are introduced as a part of event chain methodology. Event chain methodology is an uncertainty modeling and schedule network analysis technique that is focused on identifying and managing events and event chains that affect project schedules. Event chain methodology is the next advance beyond critical path method and critical chain project management. == Rules == Event chain diagrams are presented on the Gantt chart according to the specification. This specification is a set of rules, which can be understood by anybody using this diagram: # All events are shown as arrows. Names and/or IDs of events are shown next to the arrow. # Events with negative impacts (risks) are represented by down arrows; events with positive impacts (opportunities) are represented by up arrows. # Individual events are connected by lines representing the event chain. # A sender event with multiple connecting lines to receivers represents multicasting. # Events affecting all activities (global events) are shown outside Gantt chart. Threats are shown at the top of the diagram. Opportunities are shown at the bottom of the diagram. Often event chain diagrams can become very complex. In these cases, some details of the diagram do not need to be shown. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Event chain diagram」の詳細全文を読む スポンサード リンク
