A task is an activity with requirements for a specific Input and output in order to accomplish a specific objective.
- AKA: Problem.
- Context:
- It can have Task Requirements, such as task mandates or task constraints.
- It can be solved by a System (with prerequisity capabilities that, for example, implements a process or algorithm).
- It can range from being a Performed Task to being an Unperformed Task.
- It can range from being an Unplanned Task to being a Planned Task.
- It can range from being an Informally-Defined Task to being a Formally-Defined Task.
- It can range, depending on how much/little human participation is required, from being a Manual Task to being a Hybrid Task to being an Automated Task.
- It can be associated to a Benchmark Task (to evaluate task performance).
- It can range from being a General Task Type (such as searching) to being a Domain Specific Task (such as semantic role labeling).
- It can be associated with a Task Solution Attempt.
- It can be associated with a Task Issue.
- It can be a Subtask of a Composite Task.
- It can be described by a Task Description.
- It can range, depending on the task output, from being a Well-Defined Task to being an Ill-Defined Task.
- It can range from being a Paid Task to being an Unpaid Task.
- ...
- Example(s):
- a In-Project Task.
- any General Task.
- a Computing Task, such as:
- Supervised Learning Task, which has several Supervised Learning Benchmark Tasks.
- A Relation Mention Recognition Task, a type of NLP Task.
- A Sorting Task can be solved by a Sorting System (that implements a Sorting algorithm).
- An Annotation Task (See: Penn Treebank Project.
- An n-Queens Task.
- A Knapsack Optimization Task.
- A Linear Programming Task.
- any Domain Specific Task, such as credit scoring.

- In project management, a task is an activity that needs to be accomplished within a defined period of time or by a deadline. 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.
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. [1]
