a. Multi-factor analysis for each week using all input of labor, materials and overhead together. See 'hint' below. b. Single factor analysis for each week on labor and materials separately. c. What do analyses a & b indicate about the health of this process? Is it gaining in productivity over time or not? If not, which of the factors seem to be the problem? HINT: the input and output data in the single factor analysis do not have to be in the same units of measure, but in multi-factor analysis, the different types of inputs need to be converted to the same unit of measure whether its weight, cube, count or $$, ie. you cant add labor hours and the cost of materials together, but you can add their respective costs together. Always use the simplest measure available
