a)
To determine: Productivity change for Person CL’s bakery in loaves per dollar and with an increase in labor cost.
Introduction: Productivity is a measure of the effectiveness of an individual, systems, machinery and other equipment that are used in converting inputs into outputs. In all organizations, productivity is an important determinant to know cost efficiency.
a)
Answer to Problem 13P
The productivity change with the existing labor force will be 0.293 loaves per dollar and 0.293 loaves per dollar with the new labor force.
Explanation of Solution
Given information: Person CL’s bakery makes 1,500 loaves of bread in a month. Their employees are paid $8 per hour and their total labor hours is 640 hours.
Formula to calculate productivity change:
Determine the productivity change with the existing process:
The productivity change is calculated by dividing the total loaves produced in a month by the result of the total labor hour multiplied to wages per hour.
The productivity change with the existing labor force is 0.293 loaves per dollar.
Determine the productivity change with the new process:
Given information:
Person CL’s bakery increases its productivity to 1,875 loaves of bread in a month. Employees are paid $8 per hour and total labor hours are 800 hours.
The productivity change with the new labor force is 0.293 loaves per dollar.
b)
To determine: The newproductivity change for Person CL’s bakery in loaves per dollar and with an increase in investment.
b)
Answer to Problem 13P
The new productivity for Person CL’s bakery with the existing process is 0.293 loaves per dollar and with the new process being 0.359 loaves per dollar.
Explanation of Solution
Given information:
Person CL’s bakery makes 1,500 loaves of bread in a month. The employees are paid $8 per hour and total labor hours are 640 hours.
Formula to calculate productivity change:
Determine the productivity change with existing process:
The productivity change is calculated by dividing the total loaves produced in a month by the result of the total labor hour multiplied with the wages per hour.
The productivity change with the existing labor force is 0.293 loaves per dollar.
Determine the productivity change with new process:
Given information: Person CL’s bakery increases its productivity to 1,875 loaves of bread in a month. The employees are paid $8 per hour, the total labor hours is 640 hours and an investment of $100 per month is made.
The productivity change with new process is 0.359 loaves per dollar.
c)
To determine: The percentage of productivity change for labor and investment.
c)
Answer to Problem 13P
The percentage of productivity change for labor is 0% and for investment is 22.5%.
Explanation of Solution
Labor:
Formula to calculate percentage of productivity change:
Calculate percentage change for labor:
The percentage change of productivity is calculated by subtracting the initial productivity value from change in productivity value and dividing the result by the initial productivity value.
The change in productivity value is 0.293 (refer to equation (2)) and the initial productivity value is 0.293 (refer to equation (1)).
Hence, the percentage of productivity change for labor is 0%.
Investment:
Formula to calculate percentage of productivity change:
Calculate percentage change for investment:
The percentage change of productivity is calculated by subtracting the initial productivity value from the change in productivity value and dividing the result by the initial productivity value.
The change in the productivity value is 0.359 (refer to equation (4)) and the initial productivity value is 0.293 (refer to equation (3)).
Hence, the percentage of productivity change for investment is 22.5%.

- A company that processes fruits and vegetables is able to produce 1000 cases of canned peaches in 8 hours with four workers. Each worker is paid 2 RO per hour. What are the new labor hours, if output remains the same and the productivity in terms of cases/RO increased by 15%. Round to 2 decimal places Select one: O a. 7.82 hours O b. 5,57 workers O c.

Year 1 Output (sales in $million) - 120 Labor (payroll, in $million) - 32 Capital (expenses, in $million) - 45 One-time capital investment ($million) - 10 YEAR 2 Output (sales, in $million) - 160 Labor(payroll, in $million) - 26 Capital (expenses, in $million) - 45 One time capital investment ($million) - what is Productivity year 1? What is Productivity Year 2 ? What is Change in Productivity ? What is Change in sales from Year 1 to Year 2? = Change in labor cost from Year 1 to Year 2? = Change in Capital cost from year 1 to year 2 ?= Investment required to create this change ?= ROI ? = Based on these results, is this project a good idea or not?arrow_forwardImagine that you are the Sales Assistant working from 8:30 AM to 4:30 PM including one-hour lunch break in ABC Limited. His tasks includes reviewing Sales plans, updating monthly sales reports, and handling client’s complaints.

Yes, as work outputs cannot be readily measured.arrow_forward

This came tolight during a Botswana National Productivity Centre (BNPC) seminar in Francistown onWednesday.One of the panelists, Mr Letsogile Batsetswe, a research consultant at BNPC, said poor work ethicsin both the public and private sector was considered the most problematic factor for doing businessin Botswana. He added that inadequate infrastructure, limited access to financing, corruption,inadequately educated workforce as well as restrictive labour regulations were rated as the mostproblematic across the country.The regional manager of BNPC, Mr Tshenolo Mapitse added that year after year poor work ethicswere always on the lead.
