Q11.
What is the primary purpose of task decomposition in task analysis?

a.

To determine the exact order of subtasks within a task

b.

To identify all possible subtasks within a task

c.

To break down a task into its various subtasks and their relationships

d.

To emphasize the importance of hierarchical structures in tasks

Discuss
Answer: (c).To break down a task into its various subtasks and their relationships Explanation:Task decomposition involves breaking down a task into its various subtasks and establishing their relationships within a hierarchy.
Q12.
Which technique involves using indentation to represent levels in the task hierarchy?

a.

Hierarchical task analysis (HTA)

b.

Goal-oriented cognitive models

c.

Knowledge-based techniques

d.

Entity–relation-based analysis

Discuss
Answer: (a).Hierarchical task analysis (HTA) Explanation:Hierarchical task analysis (HTA) involves using indentation to denote levels in the task hierarchy, as shown in the example.
Q13.
What does a plan in hierarchical task analysis (HTA) describe?

a.

The sequence of tasks in a hierarchical order

b.

The conditions under which subtasks are performed

c.

The internal cognitive processes of the user

d.

The interactions between actors and objects in a task

Discuss
Answer: (b).The conditions under which subtasks are performed Explanation:In HTA, a plan describes the conditions under which subtasks are performed within a hierarchy of tasks and subtasks.
Q14.
How does hierarchical task analysis (HTA) handle the order of subtask performance?

a.

Subtasks must be performed in the exact order specified in the plan.

b.

Subtasks can be performed in any order within the plan.

c.

Subtasks must always be performed in the order they are presented.

d.

Subtasks are performed randomly to ensure flexibility.

Discuss
Answer: (b).Subtasks can be performed in any order within the plan. Explanation:In HTA, subtasks can typically be performed in any order as specified within the plan, providing flexibility in task execution.
Q15.
What is the iterative process involved in producing a task hierarchy?

a.

The process of analyzing internal cognitive processes

b.

The process of identifying subtasks and arranging them hierarchically

c.

The process of observing external behavior exclusively

d.

The process of restructuring existing tasks without modifications

Discuss
Answer: (b).The process of identifying subtasks and arranging them hierarchically Explanation:The iterative process involves identifying subtasks and arranging them hierarchically based on various sources, including direct observation, expert opinion, and documentation.
Q16.
What is the purpose of applying a stopping rule in task decomposition?

a.

To ensure all subtasks are expanded indefinitely

b.

To prevent the expansion of complex motor responses

c.

To determine the appropriate level of task granularity

d.

To identify internal decision-making processes

Discuss
Answer: (c).To determine the appropriate level of task granularity Explanation:A stopping rule is applied in task decomposition to determine the appropriate level of task granularity. The level of decomposition depends on the purpose of the task analysis and the intended use of the information.
Q17.
What does the P × C rule suggest as a stopping criterion for task expansion?

a.

The probability of making a mistake (P) should be divided by the cost of the mistake ( C ).

b.

The product of the probability of making a mistake (P) and the cost of the mistake ( C ) should be above a threshold.

c.

The probability of making a mistake (P) multiplied by the cost of the mistake ( C ) should be below a threshold.

d.

The sum of the probability of making a mistake (P) and the cost of the mistake ( C ) should exceed a threshold.

Discuss
Answer: (c).The probability of making a mistake (P) multiplied by the cost of the mistake ( C ) should be below a threshold. Explanation:The P × C rule suggests that if the probability of making a mistake (P) multiplied by the cost of the mistake ( C ) is below a threshold, then stop expanding. This rule helps in determining which tasks need further expansion based on their criticality.
Q18.
When might a task involving complex motor responses not be further decomposed?

a.

When the task includes cognitive decision making

b.

When the task requires coordination with external actions

c.

When the task involves internal decision making

d.

When the task's criticality is high

Discuss
Answer: (b).When the task requires coordination with external actions Explanation:Tasks involving complex motor responses may not be further decomposed when they require coordination with external actions. Decomposing such actions may not yield useful or accurate information on how they are performed.
Q19.
How can a domain expert's input be valuable in refining a task hierarchy?

a.

By identifying expert knowledge implicit in the task hierarchy

b.

By introducing complex motor responses to the hierarchy

c.

By suggesting new subtasks for expansion

d.

By analyzing internal decision-making processes

Discuss
Answer: (a).By identifying expert knowledge implicit in the task hierarchy Explanation:A domain expert's input can be valuable in refining a task hierarchy by identifying expert knowledge implicit in the hierarchy, as well as pointing out omissions or errors in the task decomposition.
Q20.
Which term describes the situation where tasks can be performed concurrently or intermingled?

a.

Fixed sequence

b.

Optional tasks

c.

Waiting for events

d.

Time sharing

Discuss
Answer: (d).Time sharing Explanation:The term that describes the situation where tasks can be performed concurrently or intermingled is "time sharing." This implies that tasks 1 and 2, "boil water" and "empty pot," can be performed simultaneously or in close succession to each other.
