Hierarchical Task Analysis (HTA) Diagram
A Hierarchical Task Analysis (HTA) diagram is a useful tool for representing and analyzing tasks and their relationships. It is commonly used in various fields to understand the structure and complexity of tasks.
Create HTA Diagram
You can add a new HTA diagram using the Plus button in the tab bar - select the Hierarchical Task Analysis item from the Other group. You can also use the New Diagram dialog (accessible from the ribbon / Project tab / Content group / Add New Diagram button) to choose the Hierarchical Task Analysis diagram type and add it to the project.
To construct an HTA diagram, users can use the tools in the toolbox. The Task tool allows users to create rectangular task elements, which are arranged in a hierarchical structure. The Plan tool allows users to connect tasks using connectors, which represent the relationships between the tasks.
Task
In the HTA diagram, tasks are represented as rectangles and are numbered in a hierarchical way. Tasks at the top level are numbered 1, 2, 3, etc., and sub-tasks are numbered according to their parent task, such as 1.1, 1.2, 1.3, etc. The task numbers are displayed in the bottom-right corner of each task element. If a task does not have any sub-tasks, it is represented with a line under the rectangle.
Plan
To create a plan between two tasks, users can use the drag-and-drop method to connect the tasks. This can be done by dragging the Plan tool from the parent task to the sub-task, creating a connector between the two elements.
