Case Study 15.3 Hawlins Manufacturing – Further instruction and guidance.
Ross Hawlins had done it all at Hawlins Manufacturing company founded by his grandfather 63 years ago. Among his many duties, Ross oversaw all the plant’s operations, a task that had grown in responsibility given the company’s rapid growth over the past three decades. When Ross’s grandfather founded the company, there were only two manufacturing sites. Expansion and acquisition of competitors over the years had caused that number to grow to more than 50 manufacturing plants in 18 states.

Hawlins had a simple process that produced only two products, but the demand for these products was strong, and Ross had spent millions of dollars upgrading his facilities over the past decade. Consequently, most of the company’s equipment was less than 10 years old on average. Hawlins’s two products were made for local markets because prohibitive shipping costs prevented shipping them long distances.

Product demand was sufficiently strong to support two manufacturing shifts (day and night) at every plant, and every plant had the capability to manufacture both products sold by Hawlins. Recently, the management team at Hawlins noticed that there were differences output levels across the various plants. They were uncertain what, if anything, might explain these differences. Clearly, if some plants were more productive than others, there might be some meaningful insights that could be standardized across plants to boost overall productivity.

Ross asked Lisa Chandler, an industrial engineer at the company’s headquarters, to conduct a study of the plant’s productivity. Lisa randomly sampled 159 weeks of output from various plants together with the number of plant employees working that week, the plants’ average age in years, the product mix produced that week (either product A or B), and whether the output was from the day or night shift. The sampled data are in the file Hawlins Manufacturing. The Hawlins management team is expecting a written report a expecting a written report and a presentation by Lisa when it meets again next Tuesday.
