Q.5
BC corporation, a manufacturer of heavy trucks had a long, sad and bitter history of employee relations. Engineers and technicians dominated the culture. One of the company's assembly plant devoted major recourses to statistical process control. An entire department staffed with engineers justified its existence by keeping control charts. The engineers collected and stored data on a computer and posted the charts in every production department once each week. They also posted lists of problems and defects attributable to each department. Another department kept itself busy with "work redesign" and "assembly line balancing". The plant was highly product focused. Material moved smoothly from one operation to the next. Subassemblies flowed into assemblies like the tributaries of a river, all moving towards the final assembly line.
Despite this effort, quality was mediocre at best. BC corporation devoted more factory space to rework and repair operations than to the original assembly. The individual and social aspects of the system were largely ignored. People lacked interpersonal skills, common goals and trust and they could not hope to attain these qualities under the existing power structure and reward system.
Summarize the case and answer the following questions:
A. Quality management is always critical for all the organizations. How six sigma will help the firm in maintaining quality?
B. Do you think that the system developed by the firm is good? Support your answer with reasons.
OR
A. Comment on the human resource management of BC corporation
B. If you take over as CEO of this firm, what changes would you like to make? How would you begin?
