Software Development Specialists (SDS) is involved with developing software for customers in the banking industry. SDS breaks a large programming project into teams that perform the necessary steps. Team A is responsible for going from general systems design all the way through to actual systems testing. This involves 18 separate activities. Team B is then responsible for the final installation. To determine cost and time factors, optimistic, most likely, and pessimistic time estimates have been made for all of the 18 activities involved for team A.

How long will it take for team A to complete their programming assignment? What would happen if activity 5, writing detailed program specifications, had larger time estimates? Assume that these larger time estimates are 12, 14, and15.
