In project management, a task is an activity that needs to be accomplished within a defined period of time or by a deadline to work towards work-related goals. It is a small essential piece of a job that serves as a means to differentiate various components of a project. A task can be broken down into assignments which should also have a defined start and end date or a deadline for completion. One or more assignments on a task puts the task under execution. Completion of all assignments on a specific task normally renders the task completed. Tasks can be linked together to create dependencies.
Tasks completion generally requires the coordination of others. Coordinated human interaction takes on the role of combining the integration of time, energy, effort, ability, and resources of multiple individuals to meet a common goal. Coordination can also be thought of as the critical mechanism that links or ties together the efforts on the singular level to that of the larger task being completed by multiple members. Coordination allows for the successful completion of the otherwise larger tasks that one might encounter.
