Task decomposition is a planning method that lets divide a broader task into smaller pieces of work or sub-tasks. The key advantage of using this method is that it provides a framework for dealing with larger action items at the lowest possible level through creating hierarchical structures and breakdowns. Such a framework provides simplicity in planning and performing various tasks and jobs.
If to be more specific about task decomposition and its contribution to task planning, the following benefits should be highlighted:
- Creating a big-picture view of root tasks through designing breakdowns and hierarchical structures
- Using task models in planning larger tasks
- Using sub-tasks as the smallest and simplest activities to perform smaller goals
- Setting dependencies between sub-tasks to determine preferred execution sequence
- Describe workflow as a series of constituent steps
- Keeping focus on every sub-task with ease
- Developing a graph that shows task flows and relationships between sub-tasks
- Integrating task decompositions with larger hierarchies such as project breakdown structures and process flows.
