Tony and Peggy Sue graduated from a university in Texas last May. She received a degree in elementary education, and he graduated from the culinary school. They both now work in the Dallas area. Peggy Sue teaches, and Tony is a chef at a resort hotel restaurant. It is Christmas Day and Tony asks Peggy Sue to marry him. She excitedly accepts. They set a wedding date of June 30.

Tony is from New York City. He is the only son of “Big Tony” and Carmella. He is known as “Little Tony” to his family. He has three younger sisters, none of whom are yet married. The family owns a restaurant called Big Tony’s, and all four children have worked in the restaurant since they were young. They have a large extended family with many relatives, most of whom live in New York City. They also have many friends in the neighbourhood.

Peggy Sue is from Cornfield, Nebraska. She is the youngest of four sisters.

She and her sisters worked on the family farm when they were young. Her father passed away several years ago. Her mother, Mildred, now lives alone in the family farmhouse and leases the farmland to a neighbouring farmer. Peggy Sue’s sisters all married local men and all live in Cornfield. All of their weddings were small (about 50 people), simple, and pretty much the same. Mildred has the wedding plans down to almost a standard operating procedure—9:00 A.M. ceremony at the small church, followed by a buffet brunch in the church weddings because the income from the farm had been pretty meagre. Peggy Sue’s sisters did not go to college, and she had to take out loans to pay for her college expenses. Tony and Peggy Sue decide to call home and announce the good news about their engagement and the forthcoming wedding.

Tony calls home and tells his mom, Carmella, the news. She replies, “That’s great, honey! I’ve been waiting for this day. I can’t believe my little baby is getting married. I’m so excited. We’re going to have the biggest, best wedding ever.

All our friends and family will come to celebrate. We’ll probably have 300 people. And, of course, we’ll have the reception at our restaurant; the banquet room should be big enough. I’ll tell your cousin Vinnie that you want him to be best man. You grew up together, although you haven’t seen much of each other since you went off to college in Texas. I’ll call Aunt Lucy as soon as we’re done talking and tell her that we want her little Maria and Teresa to be flower girls and little Nicky to be ring bearer. And, oh, I almost forgot the most important thing— your sisters, they’ll all be bridesmaids. I already know what colour their gowns will be—a deep rose; they’ll be gorgeous. And sweetie, I didn’t ask your papa yet, but I know he’ll agree with me—on Monday, I’m going to call my friend Francine, the travel agent, and get two tickets for you for a two-week honeymoon in Italy. You’ve never been there, and you must go. It will be a gift from your papa and me. And tell Peggy Lee or Peggy Susie or whatever congratulations. We are so

happy for both of you. It’s your wedding, and I don’t want to interfere. I’ll just be here to help. You know what I’m saying. So, my little Tony, whatever you want me to do, you just tell me. And one more thing, I’ll see Father Frank after Mass on Sunday and tell him to mark his calendar already for a two o’clock ceremony on June 30. Goodbye, my big boy. I’ll tell Papa you called. And I can’t wait to start telling everybody to get ready to party on June 30.”

Peggy Sue also calls her mom to tell her the news about the upcoming wedding. Mildred responds, “That’s wonderful, dear. I’m glad you’re finally getting married. You waited so long with going off to college and everything. I’ll start getting everything ready. I know how to do this in my sleep by now. I’ll mention it to Reverend Johnson after Sunday service. I’ll tell your sisters to expect to be bridesmaids again in keeping with the family tradition. I guess Holley will be the matron of honor; it’s her turn. By the way, she’s expecting her third child probably right around the same time as your wedding, but I don’t think that will matter. Well, I guess pretty soon you’ll be having babies of your own, like all your sisters. I’m glad you are finally settling down. You should really be thinking about moving back home, now that you are done with college. I saw Emma Miller, your second-grade teacher, at the grocery store the other day. She told

me she is retiring. I told her you would be excited to hear that and probably want to apply for her job.”

“She said she didn’t think they would have too many people applying so you would have a good chance. You could move in with me. The house is so big and lonely. There is plenty of room, and I can help you watch your babies. And your boyfriend, Tony—isn’t he a cook or something? I’m sure he could probably get a job at the diner in town. Oh dear, I’m so happy. I’ve been praying that you would come back ever since you left. I’ll tell all your sisters the news when they all come over for family dinner tonight. It won’t be long before we’re all together

again. Goodbye, my dear, and you be careful in that big city.”

Tony and Peggy Sue start discussing their wedding. They decide they want a big wedding—with their families and friends, including a lot of their college friends. They want an outdoor ceremony and outdoor reception, including plenty of food, music, and dancing into the night. They are not sure how much it will cost, though, and realize Peggy Sue’s mother cannot afford to pay for the wedding, so they will have to pay for it themselves. Both Tony and Peggy Sue have college loans to pay back, but they hope that the money gifts they get from the wedding guests will be enough to pay for the wedding expenses and maybe have some left over for a honeymoon.

It is now New Year’s Day, and Tony and Peggy Sue decide to sit down and start laying out the detailed plan of all the things they need to do to get ready for their wedding.

CASE QUESTIONS

Develop an estimated duration for each activity.
Using a project start time of 0 (or January 1) and a required project completion time of 180 days (or June 30), calculate the ES, EF, LS, and LF times and TS for each activity. If your calculations result in a project schedule with negative TS, revise the project scope, activity estimated durations, and/or sequence or dependent relationships among activities to arrive at an acceptable baseline schedule for completing the project within 180 days (or by June 30). Describe the revisions you made.
Determine the critical path, and identify the activities that make up the critical path.
Produce a bar chart (Gantt chart) based on the ES and EF times from the schedule in item 2.

Step 1: Activities and Estimated Durations

Here’s a breakdown of potential activities involved in wedding planning with estimated durations:

Activity

Duration (days)

1. Set Wedding Budget

2. Book Venue

3. Select Caterer

4. Send Save-the-Dates

5. Book Photographer

6. Select Music/Band

7. Order Wedding Dress

8. Select Flowers

9. Send Invitations

10. Plan Ceremony Details

11. Plan Reception Details

12. Finalize Guest List

13. Create Seating Chart

14. Confirm RSVPs

15. Arrange Transportation

16. Rehearsal Dinner Planning

17. Wedding Rehearsal

18. Wedding Day

Step 2: Dependencies

Defining dependencies among the activities is crucial to understand the project flow. Here’s a basic overview:

Set Wedding Budget → all activities dependent on budget.
Book Venue → Select Caterer, Send Invitations.
Order Wedding Dress → Select Flowers.
Send Invitations → Confirm RSVPs, Create Seating Chart.
Finalize Guest List → Create Seating Chart.

Step 3: Calculate Schedule (ES, EF, LS, LF, TS)

Now we will calculate the Early Start (ES), Early Finish (EF), Late Start (LS), Late Finish (LF), and Total Slack (TS) for each activity based on the dependencies and durations.

Schedule Calculation

Let’s assume the start date is January 1 (Day 0), and we’ll calculate the earliest and latest times.

13. Create Seating Chart

14. Confirm RSVPs

15. Arrange Transportation

16. Rehearsal Dinner Planning

17. Wedding Rehearsal

18. Wedding Day

Step 4: Identify Critical Path

Since all activities show zero total slack, they all lie on the critical path. The critical path is essentially the longest path through the project, determining the shortest time to complete the project.

question step by step:

2024-10-09 06:54:10 UTC

1. Develop an Estimated Duration for Each Activity

Here are some key activities involved in wedding planning along with estimated durations (based on general experience):

Book Venue: 20 days

Send Invitations: 10 days (must be done after booking the venue)

Select Caterer: 15 days

Order and Choose Wedding Dress and Attire: 60 days (since fittings are needed)

Choose Music/DJ: 15 days

Arrange Decorations: 20 days

Hire Photographer: 10 days

Wedding Rehearsal: 1 day (typically held the day before the wedding)

Confirm all vendors: 5 days

Set up venue for the wedding day: 2 days

These durations will help with scheduling the wedding.

2. Calculate the ES, EF, LS, LF, and TS Times

Let's outline a rough sequence of events using the estimated start time (ES) and finish time (EF) for each task. We begin with January 1st as time 0 and need to complete all activities by June 30, which corresponds to 180 days.

We use the following formula to calculate times:

ES (Early Start): The earliest time the activity can start.

EF (Early Finish): EF = ES + Duration.

LS (Late Start): The latest time an activity can start without delaying the project.

LF (Late Finish): LF = LS + Duration.

TS (Total Slack): TS = LS - ES (amount of flexibility).

Here’s how we would calculate each value for a few key activities:

Duration (days)

Critical Path: The activities with zero slack (TS = 0) make up the critical path. This path determines the shortest time to complete the project, and any delay in these tasks will delay the entire project.

3. Determine the Critical Path

The critical path is the longest path through the project network, where each task must be completed on time, or the entire project will be delayed. Based on the table:

Book Venue → Send Invitations → Select Caterer → Order Wedding Dress & Attire → Choose Music/DJ → Arrange Decorations → Hire Photographer → Confirm All Vendors → Set Up Venue → Wedding Rehearsal → Wedding Day

These tasks all have a total slack (TS) of zero, meaning they are on the critical path.

4. Produce a Bar Chart (Gantt Chart)

To visualize the project, we can create a Gantt chart showing the timeline for each activity. You could use Excel or project management software to create the Gantt chart. Below is an example of how the chart could look, with each row representing an activity and the corresponding start and finish times:

mathematica

| Activity | Jan | Feb | Mar | Apr | May | Jun |

|----------------------------|-----|-----|-----|-----|-----|-----|

| Book Venue |■■■■■■■■■■■■■■■■■■■■|

| Send Invitations | ■■■■■■■■■|

| Select Caterer | ■■■■■■■■■■■|

| Order Wedding Dress & Attire| ■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■|

| Arrange Decorations | ■■■■■■■■■■■■■■■|

| Hire Photographer | ■■■■■■■|

| Confirm All Vendors | ■■■■■|

| Set Up Venue | ■■■|

| Wedding Rehearsal | ■|

| Wedding Day | ■|

In a Gantt chart, the blocks represent the duration of each activity and when they start and finish. Activities on the critical path are usually highlighted in a different color.This method will ensure that Tony and Peggy Sue's wedding is planned on time and within their constraints.

Group 1 – Wedding Project Plan: Case Study Session 5

Project Overview

Tony and Peggy Sue, recently engaged, are planning a summer wedding on June 30. Given their differing family traditions, they want a celebration that reflects their shared values, with a large gathering, music, and festivities. As they're covering the expenses themselves, they hope monetary gifts from guests will help offset the costs.

Project Objective

The goal is to successfully plan and execute an outdoor wedding and reception by June 30, ensuring all necessary arrangements — including venue, catering, attire, and guest management — are completed on time and within a self-funded budget.
