You are leading a research project that will require between 10 and 20 aerospace engineers. Some senior-level aerospace engineers are available. They are more productive than junior-level engineers, who cost less and who are available as well. You want to determine the optimal combination of senior- and junior-level personnel. In this situation, the appropriate technique to use is to:

A. * Conduct a design of experiments B. Use the Ishikawa diagram to pinpoint the problem C. Prepare a control chart D. Analyze the process using a Pareto diagram
