To create a time schedule for the actions, you firstly identify the time required to complete each action. By representing this information on the diagram you can calculate at what stage, relative to the starting time, each action will commence and finish, and determine the total time required to achieve the objective. Simple plans can be represented by a chart which uses bars to show the sequence and duration of the actions.
More complex plans require a more flexible structure, like a chain diagram or flow chart. Diagrams help you to arrange the actions in a way which makes the best use of time and other resources. In drawing up a schedule. it's important not to be over-optimistic in the time you allow for each action. Additional time is required to accommodate delays and unforeseen obstacles, particularly with actions which must be completed on time or which are susceptible to delays.
