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. 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. In most projects, tasks may suffer one of two major drawbacks: * Task dependency: Which is normal as most tasks rely on others to get done. However, this can lead to the stagnation of a project when many tasks cannot get started unless others are finished. * Unclear understanding of the term ''complete'': For example, if a task is 90% complete, does this mean that it will take only 1/9 of the time already spent on this task to finish it? Although this is mathematically sound, it is rarely the case when it comes to practice.〔McIlree, Robert (How ‘Percent-Complete’ Is That Task Again? ), PM Hut (Last accessed 8 November 2009).〕 ==See also== * Task management 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Task (project management)」の詳細全文を読む スポンサード リンク
