Questions from this subtopic
Each one with the model answer underneath.
- 1
Define productivity.
Model answer
Productivity is a measure of output per unit of input, most often output per worker or per hour worked.
- 2
Define efficiency in an operations context.
Model answer
Efficiency is producing a given output using the smallest possible quantity of inputs, so that waste and cost per unit are as low as possible.
- 3
What is meant by effectiveness?
Model answer
Effectiveness is how well the operation achieves what it set out to achieve, such as meeting the specification, the deadline or the customer's requirement.
- 4
What is the difference between being efficient and being effective?
Model answer
An efficient operation uses few resources while an effective one delivers the right result, so a factory can make products very cheaply and still be ineffective if they are not what the customer ordered.
- 5
A workshop makes 500 units a day at the lowest cost in its industry, but a third of them are the wrong specification. Is it efficient, effective, or neither?
Model answer
It appears efficient in its use of resources but it is not effective, because a third of its output does not do the job it was made for.
- 6
How does improving efficiency raise productivity?
Model answer
Less input is consumed making each unit, so the same workers and machines turn out more usable output in the same time.
