Maduro Cleaning is a small organization that provides cleaning services to both residential and commercial clients. As a small organization, the owner assigns crews of two, three, or four employees to jobs each morning but the owner does not have a good method of determining a reasonable amount of time that each cleaning should take. The owner decided to keep data on job times and crew sizes in the hopes of developing a productivity measure. Address the following requirements:
- Calculate which of the crew sizes has the best productivity per worker and explain your method.
- Evaluate your outcome and the possible reasons that would explain those results.
- Project what the productivity might be for a crew size of five and explain your reasoning.
Crew Size Avg: Productivity per Crew
- 2: 3765 square meters per day
- 3: 4915 square meters per day
- 4: 6309 square meters per day
Directions:
- Your assignment is required to be four pages in length, which does not include the title page and reference pages, which are never a part of the content minimum requirements.
- Support your submission with course material concepts, principles, and theories from the textbook and at least three scholarly, peer-reviewed journal articles.
- Formatted according to APA 7th.
- Each paragraph should have headline.

The material in this book is intended as an introduction to the field of operations management. The topics covered include both strategic issues and practical applications. Among the topics are forecasting, product and service design, capacity planning, management of quality and quality control, inven- tory management, scheduling, supply chain management, and project management.
My purpose in revising this book continues to be to provide a clear presentation of the concepts, tools, and applications of the field of operations management. Operations management is evolving and growing, and I have found updating and integrat- ing new material to be both rewarding and challenging, particu- larly due to the plethora of new developments in the field, while facing the practical limits on the length of the book.
This text offers a comprehensive and flexible amount of content that can be selected as appropriate for different courses and formats, including undergraduate, graduate, and executive education.
This allows instructors to select the chapters, or portions of chapters, that are most relevant for their purposes. That flex- ibility also extends to the choice of relative weighting of the qualitative or quantitative aspects of the material and the order in which chapters are covered because chapters do not depend on sequence. For example, some instructors cover project management early, others cover quality or lean early, etc.
As in previous editions, there are major pedagogical fea- tures designed to help students learn and understand the mate- rial. This section describes the key features of the book, the chapter elements, the supplements that are available for teach- ing the course, highlights of the eleventh edition, and sug- gested applications for classroom instruction. By providing this support, it is our hope that instructors and students will have the tools to make this learning experience a rewarding one.
What’s New in This Edition Class preparation exercises are now available for all chapters and chapter supplements. The purpose of these exercises is to introduce students to the subject matter before class in order to enhance classroom learning. These exercises are available in the Instructor’s Resource Manual. Special thanks to Linda Brooks for her help in developing the exercises.
Some content has been rewritten or added to improve clar- ity, shorten wording, or update information. New material has been added on supply chains (including a different, more realistic, way to conceptualize supply chains), as well as on product life-cycle management, 3-D printing, drones, loca- tions, and other topics. New critical thinking exercises have
been added. The explanation of learning curve time reduction has been simplified with a new diagram. Some older readings have been deleted, and new readings added on such topics as fracking, mass customization of fast foods, and self-driving vehicles.
Acknowledgments I want to thank the many contributors to this edition. Review- ers and adopters of the text have provided a “continuously improving” wealth of ideas and suggestions. It is encourag- ing to me as an author. I hope all reviewers and readers will know their suggestions were valuable, were carefully consid- ered, and are sincerely appreciated. The list includes post- publication reviewers.

2. Check the correlation coefficient to confirm that it is not close to zero using the web- site template, and then obtain the regression equation: r = −.966 This is a fairly high negative correlation. The regression equation is y = 71.85 − 6.91x
Note that the equation pertains only to unemployment levels in the range 3.6 to 9.0, because sample observations covered only that range.

Computing Productivity A company that processes fruits and vegetables is able to produce 400 cases of canned peaches in one-half hour with four workers. What is labor productivity?
Problem 1
SOLVED PROBLEMS
KEY POINTS 1. Competitive pressure often means that business organizations must frequently assess their com-
petitors’ strengths and weaknesses, as well as their own, to remain competitive. 2. Strategy formulation is critical because strategies provide direction for the organization, so they
can play a role in the success or failure of a business organization. 3. Functional strategies and supply chain strategies need to be aligned with the goals and strategies
of the overall organization. 4. The three primary business strategies are low cost, responsiveness, and differentiation. 5. Productivity is a key factor in the cost of goods and services. Increases in productivity can
become a competitive advantage. 6. High productivity is particularly important for organizations that have a strategy of low costs.

Labor productivity

Solution
Computing Multifactor Productivity A wrapping-paper company produced 2,000 rolls of paper one day. Labor cost was $160, material cost was $50, and overhead was $320. Determine the multifactor productivity.
Problem 2
mhhe.com/stevenson13e
Multifactor productivity
=
Quantity produced ______________________________
Labor cost + Material cost + Overhead
= 2,000 rolls
_______________ $160 + $50 + $320
= 3.77 rolls per dollar input
A variation of the multifactor productivity calculation incorporates the standard price in the numerator by multiplying the units by the standard price.
Solution
Computing Multifactor Productivity Compute the multifactor productivity measure for an eight-hour day in which the usable output was 300 units, produced by three workers who used 600 pounds of materials. Workers have an hourly wage of $20, and material cost is $1 per pound. Overhead is 1.5 times labor cost.
Problem 3
Multifactor productivity
= Usable output
__________________________________ Labor cost + Material cost + Overhead cost
= 300 units
_____________________________________________________ ( 3 workers × 8 hours × $20 / hour ) + ( 600 pounds × $1 / pound ) +
( 3 workers × 8 hours × $20 / hour × 1.50 )
= 300 units
________________ $480 + $600 + $720
= .167units of output per dollar of input
