Quality-Productivity

Case Study - Supreme Inc.

You have just joined the Supreme Company as a financial analyst, reporting to the Controller. Based upon your recent business education at Humber, which included a wide range of subject areas, your new boss has asked you to help her review the recent changes in the manufacturing area.

Until recently, the company had offered only a limited number of standard electric motors for sale. They had purchased raw materials and the lowest level components, but produced most of the subassemblies and all of the finished products in their own plant. The company's profitability had declined over the years and marketing believed that customers needed both more variety of product and lower prices. In early 2004, the manufacturing division had been assigned the task of recommending changes to accomplish this dual goal of increasing variety and reducing costs.

Manufacturing had recommended that they change their strategy to:

- Buy (rather than make in-house) most of the subassemblies.

As tooling-up to produce a much wider variety of subassemblies, would take several million dollars of investment and 2-3 years to implement. Retaining production of existing sub-assemblies in-house was not considered viable as their volumes were expected to drop dramatically, when the variety being offered increased. Also the company needed all the existing space for the more flexible final assembly process needed for the greater variety of products being sold.
- Build final products to customer order.

This plan had been approved in September of 2004. The plan and associated personnel layoffs were announced in October 2004, with the layoffs scheduled for December 31, 2004. The increased variety of products had been announced in October, with the first build-to-order shipments scheduled for Jan 2005.

Selected Historical Results:

Assignment:Compile a report, which includes the following:
1- Format:
- Cover Page, Table of Contents - listing all major sections of the report, and the page number where these sections start.
- Executive Summary - should be written after covering all the issues of this assignment. This section should appear after the table of contents page and allow your manager to have an immediate, short and clear understanding of the main findings and recommendations of your study. Use bullet points and specific figures.
- English usage, spelling and typing is important.
- Tables and charts should be computer generated. They must have titles, axes labeled, and data identified.

2- Calculate Labour, Material and Total Productivity (multifactor of all costs) indices, for each month and present them in a table. IE.Three indices for each month.

3- Present the 3 indices calculated in Point 2, in a line graph format, on one page.

4- Compare the 3 average productivity indices for the whole of 2004 (12 months) with the 3 average indices of July-September(only 3 months) of 2005.

a) What is the percentage change for each index?

b) Why do we use only 3 late months in 2005?

5- Did the change in manufacturing strategy deliver improvements? Comment on patterns of Total Productivity, Labour Productivity and Material productivity, before and after the change in strategy and explain the reasons for each of the 3 patterns. IE. Mention the reason(s) that a productivity index went up or down.
