1. Identify, from the list below, items that can be classified as “output” in productivity determination.
i. Number of customers serviced.
ii. Tonnes of QC-approved adhesives polymer produced by a polymer- manufacturing chemical plant.
iii. Manpower cost spent on treating chemical waste for a water treatment plant.
iv. The market value of jet fuel produced by a petroleum refining plant.

2. Labour is a common parameter that can be used as “input” in productivity determination. Labour can be measured in the following method below EXCEPT :
Number of hours worked
Lost work days due to EHS (environment, health and safety) lapses
Number of workers
Cost of workers
Productivity can be improved by :
i. Increasing input together with a smaller increase in output.
ii. Maintaining output but increasing the input.
iii. Decreasing input but with a smaller decrease in output.
iv. Decreasing input but maintaining output.

Innovation is a factor that affects an organization’s productivity. The list below is examples of innovative items EXCEPT :
Launching new products that is desired by consumers
Employing new technologies
Re-organizing the organization structures to improve response time, reduced batch cycle time, etc.
Increasing the number of machineries to cope with rising demand
5. Identify, from the list below, the CORRECT reason why enterprise can drive productivity growth.
New enterprises compete with existing firms for business for the existing market share of established product such as industrial gases, coatings, fuels such as non-leaded petrol, etc. Increased competition forces all firms to improve their productivity.
New enterprises consist of better motivated workers who tend to be more productive.
New enterprises increase the number of firms engaging in similar trades. This raises the possibility of lower taxes imposed by the authority (due to more revenue collected from the increased number of firms).
New enterprises engage in new business opportunities using new approaches, technologies, etc. This increases the competition and forces existing firms to improve their own performance or risk losing market share.
Identify, from the list below, the benefits of process automation:
i Reduce human error
ii. Reduce labour cost
iii. Improve product quality and consistency
iv. Reduce the size of the plant and inventories
i and ii

Identify, from the list below, the CORRECT description of a distributed control system (DCS).
A daily meeting between supervisors on the day allocation of resources (raw materials, manpower, etc.) for the efficient running of the plant.
A computerized control system where the controller elements are distributed throughout the plant and are connected to a central area for monitoring, adjustment of set-points, etc. The instrument can be controlled locally or from the control room.
A computerized control system where the controller elements are distributed throughout the plant. To change the set-points of the controller elements, workers will have to go to the specific controller and make the changes on-site. This prevents mistakes (workers making changes to wrong controller element, etc.).
A data collection system which automatically records the amount of raw material (feed, energy, etc.) consumed by each unit processes of a plant. This allows workers to identify the suitable unit process for work improvement activity.
8. To reduce waste generated, changes can be made to the input or raw material. This can include using a purer raw material. Identify, from the list below, how this method can help reduce the amount of waste generated.
Purer raw material has less toxicity and poses less danger to workers and the environment.
The waste produced by a purer raw material is cleaner and can be exchanged with another plant which uses the waste as a resource.
Purer raw material introduces less impurity into the process. This reduces the wastes generated by the process.
The waste produced by purer raw material usually contained substantial amount of the raw material and thus, can be reclaimed for use again in the process.
Identify, from the list below, the CORRECT definition of value added.
It is represented by the equation : value added = sales – total wages
It is generated solely by the effort of workers in the organization.
It can be expressed in various types of units (tonnes, litres, no. of customers serviced, etc.)
It represents the wealth created through the organization’s activities.
Identify, from the list below, the items that the wealth generated through the value added are distributed to.
i. Workers’ salary
ii. Dividend paid to organization’s shareholders.
iii. Cost of goods purchased to make the product
iv. Advertising fees to market the product
