A company such as Intel has a complex design and manufacturing process. For instance, one fabrication line for semiconductors typically costs more than $$1\mathrm{.}5$ billion to build. Yet the industry also has high human costs for research and development $($R&D$)$ departments. Semiconductor firms spend an average of $17$ percent of revenues on R&D$.$ For comparison the automobile industry spends a mere $3$ percent of sales on R&D$.$ Thus, Intel$$s management must be concerned with both scale of production and learning curves. When do you think managers should be more concerned with large$-$scale production runs, and when do you think they should be most concerned with practices that would foster or hinder the hiring, training, and retention of key employees?
