The development of a work breakdown structure can be challenging. It requires a good understanding of the problem and a good understanding of the proposed solution. The proposed solution must be "broken down" into its major parts, each of which may be further broken down. Comment on your experience in developing a work breakdown structure for your individual project. What was easy? What was difficult? What problems did you encounter and how did you solve them?

Suppose that a paving company produces paved parking spaces (q) using a fixed quantity of land (t) and variable quantities of cement (c) and labor (l). the firm is currently paving 1,000 parking spaces. the firm's cost of cement is $3 comma 600.003,600.00 per acre covered (c) and its cost of labor is $35.0035.00/hour (w). for the quantities of c and l that the firm has chosen, mp subscript upper c baseline equals 60mpc=60 and mp subscript upper l baseline equals 7mpl=7. is this firm minimizing its cost of producing parking spaces?
