All dates are specified as manufacturing planning calendar days. Assume that all jobs arrive on day 275.
Assume each job starts at the beginning of the day and finishes at the end of the day (a job that begins on day 275 and takes 8 days will finish on day 282, and the next job begins in the morning of day 283). Compute all times based on initiating work on day 275.
a) Using the FCFS (first come, first served ) decision rule for sequencing the jobs, the order is (assume that jobs came in the order in which they are listed in the table): ___A-B-C-D-E___
*The average tardiness (job lateness) for the sequence developed using the FCFS rule = ______ days (round your response to two decimal places).
*Calculate the percentage utilization for the sequence developed using the FCFS rule = _______ % (round your response to two decimal places).
b) Using the EDD (earliest due date) decision rule for sequencing the jobs, to determine the order of the jobs (to resolve a tie, use the order in which the jobs were received).
*Under the EDD rule, jobs are scheduled in the order in which they are due. Arrange the due dates in ascending order to perform the scheduling: _______
*Calculate the average tardiness (job lateness) for the sequence developed using the EDD rule = _________ days (round your response to two decimal places).
*Calculate the percentage utilization for the sequence developed using the EDD rule = _______ % (round your response to two decimal places).
c) Using the SPT (shortest processing time) decision rule for sequencing the jobs, determine the order of the jobs (to resolve a tie, use the order in which the jobs were received).
*Under the SPT rule, jobs are scheduled based on the ordering of the processing time with the shortest one first. Arrange the processing times in ascending order to perform the scheduling: _____________
*Calculate the average tardiness (job lateness) for the sequence developed using the SPT rule = _______ days (round your response to two decimal places).
*Calculate the percentage utilization for the sequence developed using the SPT rule = ________ % (round your response to two decimal places).
d) Using the LPT (longest processing time) decision rule for sequencing the jobs, determine the order of the jobs (to resolve a tie, use the order in which the jobs were received).
*Under the LPT rule, jobs are scheduled based on the ordering of the processing time with the longest one first. Arrange the processing times in descending order to perform the scheduling: _________
*Calculate the average tardiness (job lateness) for the sequence developed using the LPT rule =_____ days (round your response to two decimal places).
*Calculate the percentage utilization for the sequence developed using the LTP rule = ______ % (round your response to two decimal places).

Exercise Overview
Interpersonal skills refer to the ability to communicate with, understand, and motivate individuals and groups. Implicit in this definition is the notion that a manager should try to understand important characteristics of the work group(s) being supervised. Diagnostic skills help managers visualize and understand the most appropriate response to a situation. This also relates to assessing how various things are related to one another. This exercise will give you insight into the importance of both interpersonal and diagnostic skills as they relate to managing groups and teams in organizations.
Exercise Background
In other cases managers are promoted, transferred, or reassigned to a different job and take over an existing group or team. At one extreme they may inherit a highly functional and productive group; at the other extreme they may inherit a group that is dysfunctional and that has a lot of internal problems. And, of course, there are many potential possibilities between these two extremes.
Therefore, it is important that managers have the skills needed to carefully assess the current dynamics of a group in order not to create problems where none exists or to solve problems that do exist. The questions that follow focus on different scenarios in which such insights may be needed.
You have been appointed to lead a new team. The purpose of this team is to assess different potential locations for a new warehouse and to make a recommendation back to senior management. Your team has been given 30 days to make a recommendation. What type of team is this?
Management team
Quality circle
Virtual team
Problem-solving team
Work team
You have been appointed to lead an existing group. Your boss, who informed you of the assignment, made these comments: “These people have some real issues. They have been a problem for years. They stick together like family but never seem to get much work done.” Which of these would best describe this group?
High cohesiveness, high performance norms
Low cohesiveness, low performance norms
Low cohesiveness, high performance norms
High cohesiveness, low performance norms
Which of these observations is correct? Check all that apply.
In some cases, managers may want to resolve or eliminate conflict.
Conflict always decreases a team’s performance.
In some cases, managers may want to control conflict.
In some situations, managers may want to stimulate conflict.

Green Vehicle Inc., manufactures electric cars and small delivery trucks. It has just opened a new factory where the C1 car and the T1 truck can both be manufactured. To make either vehicle, processing in the assembly shop and in the paint shop are required. It takes 1/25 of a day and 1/75 of a day to paint a truck of type T1 and a car of type C1 in the paint shop, respectively. It takes 1/45 of a day to assemble either type of vehicle in the assembly shop. A T1 truck and a C1 car yield profits of $325 and $225, respectively, per vehicle sold.
Formulate the linear program that provides the combination of T1 and C1 that maximizes yield, clearly specifying (a) variables, (b) objective function and (c) constraints.

Design specifications for an arrow are that they each weigh 100 ± 10 grams. The process to make the arrows has a standard deviation of four units.
a. What is the process capability index? Assume
that the process is centered with respect to specifications.
Round your intermediate and final answers to 4 decimal
places (e.g., .12345 would be rounded as .1235, not
.1234).
| Process capability index | ? |
b. Suppose the process average shifts to 92. Calculate the new process capability index. Round your intermediate and final answers to 4 decimal places (e.g., .12345 would be rounded as .1235, not .1234).
| New process capability index | ? |
c. What is the probability of defective output
after the process shift? Round "z" values to 2 decimal
places. Round probabilities to 4 decimal places (so a probability
of .12345 would be entered as .1235, not .1234 or 12.345% or
something else).
| Probability of defective output | ? |

On Franco’s first day of work as an entry-level account manager at an advertising firm, he had lunch with three women who also were entry-level account managers at the firm. During lunch, the three women made comments to Franco that they appreciated how “fit” he was and that they were glad to have a male colleague who was “easy on the eyes” and “probably great in the sack.” Franco is very conservative about sexuality and these comments made him feel very uncomfortable. Franco quit his new job immediately after lunch and filed a sexual harassment suit against the advertising firm claiming that he experienced a hostile work environment.
Using the legal rule for determining whether a hostile work environment exists, identify two reasons why Franco is unlikely to win his lawsuit.

As part of a discussion of a proposed major restructuring, you point out that major change attempts work best when there is a “burning platform" (i.e. a great sense of urgency to change). Your boss disagrees, saying, “That’s motivating with fear. We need to change before the platform is on fire.” Take a position for or against your boss’s argument.
