For those data, calculate: (a) Partial productivity ratios for this year and the base year. (b) Productivity ratios for this year. What can you say about the company's productivity?

You have made time studies of a task that occures frequently within your plant. You find that standard time varies directly with the weight of the product. For the given values, graph time vs. weight and draw a straight line. Fill in your "estimate" for the line (i.e., visually estimate a and b below).

Given the following data, compute the production standard (pieces per hour), the standard 4% for fatigue, 8% for unavoidable delays, and 8% for personal needs. The operatoris labor cost per 100 pieces, and the standard hours per 100 pieces. The allowances are = 105%. (Instructor: Look also at Problem paid $5.00 per hour. Performance rating 12.)

Take an operation that is performed at one workstation with which you are very familiar and make a left-hand-right-hand chart of it. List the principles of motion economy and show which areas are applicable to that operation. Finally, show a revised left- hand-right-hand chart and calculate labor savings for an appropriate rate. 3. Make a flow process chart for a process with which you are familiar. Examine it and see which activities can be eliminated, combined, changed in sequence, or improved (in that order of preference). Show the revised flow process chart. 4.
