Scenario details
Shirt City is a small clothing manufacturer, specializing in creating custom, one-of-a-kind shirts. They
exclusively sell their product through their online store.
Shirt City is run by a team of three staff members: Alexa, Barry, and Claudia.
Alexa and Barry work together to manufacture shirts. Claudia manages orders, sales and delivery.
Team hours
Most of the time, team members work the following shifts:
CRICOS Provider No. 00103D Page 2 of 6
Alexa works 7.5 hours on Mondays, Tuesdays and Wednesdays;
Barry works 7.5 hours on Thursdays and Fridays; and
Claudia works 4.5 hours every weekday.
Additionally, Alexa and Claudia share responsibility for managing the Shirt City social media presence, with
Alexa working one extra hour in the evenings on Monday, Tuesday and Wednesday, and Claudia doing the
same on Thursday, Friday and Saturday.
Costs
Alexa and Barry, as skilled manufacturing staff, cost $26 per hour to employ.
Claudia, a part-time employee, costs $24 per hour to employ.
All staff are also entitled to four weeks of paid annual leave, during which a casual replacement is required
at a cost of $39 per hour.
Fixed costs such as rent and insurance are $9100 per year, and utilities costs are $260 per month.
Task 1 – Costs of operating the business
Using Excel, create a spreadsheet called operating_costs.xlsx that calculates the projected annual outgoing
costs of running Shirt City.
Your spreadsheet should be configured such that the working hours, hourly rates, and fixed and utility costs
can be varied easily.
Document your findings in your ePortfolio page (approximately 100 words).
Manufacturing shirts
Shirt City receive requests through their online store, and Claudia responds with a quote, after consulting
with a member of the manufacturing team. If the customer confirms their order, Alexa and Barry
manufacture the ordered products, and Claudia organizes delivery.
Currently, the process for generating a quote is entirely subjective, based on the requested material and
shirt size. Staff members quote an amount based on their personal experience.
For several months, staff have been keeping track of the quote date, material, size, quote amount, and
manufacturing cost for each order in a spreadsheet. As each product is hand-made, the manufacturing
cost may vary between similar orders.
If a quote was not accepted by the customer, then manufacturing cost is not included.
This spreadsheet is available for download on Moodle.
Task 2 – Order information
Using Excel, process the history of orders spreadsheet and use appropriate charts to visualize:
How some aspect of quoting or manufacturing has changed over time; and
How the quote amount differed for each staff member.
You will need to find a way to use Excel to associate each quote with a staff member.
CRICOS Provider No. 00103D Page 3 of 6
Describe your approach and your findings in your ePortfolio (approximately 250-400 words), and attach the
Excel file to your page.
Task 3 – Price consistency
Using Excel, analyse the historical data you have available, and create a spreadsheet that allows a member
of the Shirt City team to enter the shirt material and size, and gives a quote amount.
Ensure that you include enough text and formatting to make your spreadsheet usable by a member of the
Shirt City team (or by a University lecturer).
You may base your quote amount either on historical averages, or to ensure that Shirt City makes a profit.
Validate your quoting approach by applying your formula to historical data.
Justify your approach in your ePortfolio (approximately 150 words), and attach your Excel file to your
ePortfolio.
Process improvement
The team want to improve their quoting process to reduce time spent waiting for customers to approve
quotes.
They would like to start manufacturing immediately for orders that they might be able to sell in future,
even if the customer does not go ahead with the order.
That is, they would like to change to the processes indicated in the following swimlane diagrams:

Task 4 – Process improvement
Extend your spreadsheet page from task 3 to automate the above processes, allowing a member of the
team to enter the shirt material and size, and in addition to the quote amount indicate whether to start
manufacturing immediately.
It is up to you do determine how to determine which items are popular.
Justify your approach in your ePortfolio (approximately 150 words), and attach your Excel file to your
ePortfolio.
