Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
FFBDs can be developed in a series of levels. FFBDs show the same tasks identified through functional decomposition and display them in their logical, sequential relationship. For example, the entire flight mission of a spacecraft can be defined in a top level FFBD, as shown in Figure 2. Each block in the first level diagram can then be ...
Contemporary time sheet. A timesheet (or time sheet) is a method for recording the amount of a worker's time spent on each job.

Gantt charts can be used to show current schedule status using percent-complete shadings and a vertical "TODAY" line. Gantt charts are sometimes equated with bar charts. [8] [9] Gantt charts are usually created initially using an early start time approach, where each task is scheduled to start immediately when its prerequisites are complete.
