The Dependency Chain is an aspect of project management when planning weddings. It is a series of actions where each action is dependent on the outcome of the previous action. This illustrates the relationship between tasks and shows how one task’s completion affects the start of another. When planning a wedding, understanding the Dependency Chain ensures everything runs smoothly and potential bottlenecks are identified and addressed. Without an understanding of the Dependency Chain, weddings can face delays and disruptions due to unforeseen dependencies. By mapping out the Dependency Chain early in the wedding planning process, project managers mitigate risks and ensure a successful wedding event.
