Peter Weill's produced a study that identified the 4 main categories that make up a company's IT portfolio: the IT infrastructure, transactional systems, informational systems, and strategic systems. Weill's research shows that most companies spend a majority of their IT portfolio on the 1. and the least amount of money is spent on the 2. . A company that is seeking to be highly agile should spend more money on the 3. to provide a nimble platform and less money on the 4. which tends to lock in current business processes.

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?
