CIEE Task Analysis & Job Demands 2

Question 1

Which method uses predetermined time values to estimate how long each element of a task should take without direct observation?

Accepted Answer

Methods Time Measurement (MTM)

Answer

MTM is a predetermined motion time system that assigns standard time values to basic human motions, enabling task duration estimation without stopwatch measurement.

Question 2

An ergonomic evaluator is assessing a packaging line where workers rotate among four stations every 30 minutes. What is the PRIMARY ergonomic benefit of this rotation schedule?

Accepted Answer

Reduces cumulative loading on any single muscle group

Answer

Job rotation distributes musculoskeletal load across different body regions, reducing cumulative exposure and lowering injury risk.

Question 3

In a Functional Job Analysis (FJA), the 'Things' scale rates worker interaction with:

Accepted Answer

Inanimate objects, machines, and materials

Answer

FJA uses three scales — Data, People, and Things — where the Things scale measures the complexity of a worker's relationship with physical objects and equipment.

Question 4

A task requires workers to exert 45 lbs of push force on a cart at waist height across a level surface. Which NIOSH guideline element is most directly violated?

Accepted Answer

Initial push force limit for frequent pushing tasks

Answer

NIOSH and Liberty Mutual guidelines specify acceptable initial and sustained push/pull force limits; 45 lbs initial force on a level surface exceeds recommended limits for most working populations.

Question 5

Which element of a task analysis describes the sensory information a worker must receive and interpret to perform a step correctly?

Accepted Answer

Perceptual requirements

Answer

Perceptual requirements capture the visual, auditory, or tactile cues a worker must detect and process to execute a task step safely and correctly.
