Problem-Based Learning (PBL) Scenario: Amazing Coffee Houses (ACHs)

Company Biography

Amazing Coffee Houses (ACHs) is a small but established company in the coffee industry. It is based in northern Chicago, IL and employs over 100 workers locally in its 10 stores. Its current Chief Executive Officer (CEO) and Chairman of the Board, Sam Ryder, founded the company back in 1994 with his wife, Gloria Ryder. Gloria has served as the company’s Chief Financial Officer (CFO) since it was founded. Both Sam and Gloria graduated from the #1 ranked MBA program in the country and bring a lot of corporate experience to the business. Sam was a Senior Vice President (SVP) in Marketing and Sales at another company for many years before deciding to venture off to start ACHs with his wife. Gloria also worked for that same company and held the position of Finance Director.

The company is known for its own brand of gourmet coffee and low fat donuts, as well as for their own line of stainless steel coffee mugs that are able to keep drinks hot for 12 hours straight. The workforce is comprised mostly of bakers, managers, baristas, greeters, clerks, and cashiers. They also work closely with several large suppliers and distributors in the United States.

Problem

The company has a loyal customer base throughout Chicago and is known for its personalized service and quality food and drinks. Because the economic conditions have greatly improved throughout the United States and the company now has a well-established name and brands, ACHs is looking to expand in markets beyond Chicago. The first market it has made a decision to expand into is 81 miles away, Milwaukee, WI. The company has worked through a local real estate agent and was able to strike a great deal on a 10-year lease in a great location. Management thinks Milwaukee is where the next 10 stores will be opened. However, Sam and Gloria have never operated a multi-state business before and are worried they will fail to accomplish their expansion goal timely. Sam has made it clear to Gloria that one day, his vision is to take ACHs to every city in America.

Opportunity

Sam has no project management experience and has decided to hire a project manager to manage the expansion project in Milwaukee, WI. After thorough evaluation and dozens of interviews, they have asked Jim Young, a rising star at the company, to take on the role of project manager to lead a team of five people from different departments to create a project plan for the new site.

Jim Young currently serves as a store manager for the biggest two coffee shops. Prior to this role, he worked as a store supervisor for the company. During his time with the company, he has worked on many of the new shop development projects as a team leader and helped to renovate some of the company’s existing shops. People in his business units speak highly of his leadership and coaching style. Though Jim has worked on project teams and supervised functional departments, he has never acted as the project manager before. He knows there are a lot of moving parts in managing a project. He is worried about his ability to lead a new team of people with whom he has never worked before. He is concerned about his lack of experience and knowledge to manage the entire life cycle of a project from start to finish within budget, quality, time, and scope. In previous projects, he remembers Sam and Gloria having differences in budget, scope, and resource allocation, which caused a lot of confusion among the project team members and vendors. Jim is also concerned that their personal relationship will interfere in this project.

You will be working with Jim Young as a project team member with four other professionals in the company. You have only worked at ACHs for 4 years. Prior to your tenure at ACHs, you worked as an associate project manager for a construction company on the West Coast. You have worked on many different projects and are familiar with project management terms, methodologies, tools, and techniques. You earned several certifications relating to project management including a PMP and have an MBA in logistics. Although, you have never worked with Jim Young or anyone else on the new team, you are very excited about the opportunity to make a difference.

Project Background Details

Amazing Coffee Houses (ACHs) is a coffee shop that will be located in Milwaukee, WI. We have been able to purchase our own building within the city near Milwaukee’s top tourist attraction site near the Gold Rock Museum. The building is not renovated. Our market analysis of Milwaukee, WI indicated the city is the top city for coffee drinking in WI. Because we’re close to the city’s museum, we plan to become the top destination for local and American and foreign customers who visit Milwaukee each year.

Our customers will have a wide range of coffee flavors to choose from including dark roast to light roast as well as specialty flavors throughout the year. They will also enjoy freshly baked low-fat donuts that aren’t available anywhere in the state. ACHs will hold true to its vision and mission of providing customers with a premier café experience. By creating a new twist for the café experience, ACHs will increase sales by more than $125,000 over the next three years and maintain a gross margin of 70%. The shop is 5,500 square foot of open space. Our plan is to have 2 bathrooms, a coffee bar, and enough tables to seat at least 50 customers. This is a coffee shop that also makes and sells donuts. The renovation must account for all that is needed to get the shop ready for both coffee and donuts. The project has an initial budget of $650,000. It is now January and Sam and Gloria would like the new location to be up and running no later on July 4th.

Assignment-

At the next meeting, you and the team had a very productive discussion on your findings related to the identification of all of the project activities that must happen to start and finish your project. You even took a step further in working with your team members to estimate resources and cost for each of the activities. Everyone feels that it is time to present your findings to Sam and Gloria and provide them with a baseline estimate of how long this project will most likely cost in terms of time and dollars.

“Thanks for educating us on the schedule development planning,” says Jerry to you. “We have some great information here, but I think it is too much detail to present to Sam and Gloria.”

“I agree,” says Melissa. “Does anyone have any ideas on how best to present this information?”

“We should go ahead and plug this information into a project schedule that both Sam and Gloria know and will appreciate. We ought to establish a project baseline at this time. We should define the tasks, start and finish dates, duration’s, predecessors (sequence of activities), resource names, and possibly cost,” says Sara.

“The project schedule should account for all of the activities that must happen. It must not be less than 30–50 activities and subactivities,” you say.

“Oh, that’s great!” says Jim. “Do you think you can prepare it for the team by next week?”

Assignment- Part 1- Length Varies but I would say 2-4 pages

Tips: Start by looking at the WBS activities that you defined last week. Think about how you could decompose your work packages into activities and subactivities to complete this coffee house project. You should use all of the project artifacts (deliverables) you produced so far and the given project scenario to identify all of the activities that are needed.

You should be able to come up with 30–100 activities easily for your schedule baseline. Once those activities have been identified, finish your schedule by plugging in start and finish dates, durations, predecessor relationships, and adding cost and resource names. Resource names and cost can be added in the main summary page or directly in the resource sheet. Your project name must go in the first row, and all other activates should be indented under it. You should link all activities to summary tasks and subactivities to the main activity. You may make assumptions for any of this work, and estimates do not need to be real. You should save the finished project file as: “Week 3 deliverable_your name.”

Part 2-

Touch up on Assignment- Professors notes for Assignments- Please look at the Learning Materials tab in the portal and open the scenario section (which is above). Write to that scenario. It should only require a little more work and you will have it. I uploaded the assignment which is project_charter_for_coffee_shop.docx. I’m having trouble figuring out what else I need to add to the assignment so any suggestions would be great!!

NOTE: I uploaded assignment details and work that was completed for Unit 1 and 2 in order to have a good take on the assignment at hand. Thanks

The assignment is undertaken via an informative visual Executive Report (utilising PowerPoint) based on the case analyses I have undertaken. The Word Count is limited to 2000 words (+/- 10%). You may use the ‘Notes’ section in PowerPoint to elaborate on any points contained in the visual presentation (this may be in bullet-point format) but will still count towards 2,000 words. This course is about strategic decision-making so it is important to analysis the decision the company did.

Powerpoint should include five parts that are vision and values of the company, competitive analysis (Five forces and PEST should be used), company capabilities (VRIO should be used), company preference (balance scorecard should be used) and future options and recommendations. I have put the detailed information about this assignment in the file. It is worth noting that I have provided all the information about the case, so there is no need to find additional information about the case. However, the academic articles still need to be found (need to write intext citation and reference).

Please check the attached document below. (You don’t need to meet all the requirements, i.e. the 3rd requirement)

Your job is improved my package to various ways. For examples,

1. In the current implementation, only one CPU is used in the algorithm. Make it possible to use more than one CPUs. Note that you should let users to decide if they want to use parallelization.
2. Allow users to specify file names to run the model rather than loading the whole data in the main process.
3. Functions are written in pure R, it is possible, for example, to convert the function lm1 to c++ code. Your might need look at how RcppArmadillo’s fastLm.R and fastLm.cpp. (Spoiler, it is not easy, but if you insist, here is a some slides about it: https://scholar.princeton.edu/sites/default/files/q-aps/files/slides_day4_am.pdf)
4. Write tests and documentations
5. More models? Logistic regression? GLM?
6. You should also write a few pages Rmarkdown documentation to explain your work. One recommendation way is to put the documentation as a vignette. (If you want to use tidyverse in the the vignettes, run usethis::use_package("tidyverse", type = "suggest") to add tidyverse in the suggest field of DESCRIPTION.)
