Case Scenario
Kroko-Fit operates 7 days a week from 6am to 10pm. However, due to increasing
competition, particularly in gym service, Kroko-Fit is considering opening its gym
facilities for 24 hours a day, 7 days a week.
Kroko-Fit has a swimming pool, a gym, 4 tennis courts, 8 squash courts, and a bowling
hall. Attached to the center is Kroko-Shop, a shop that stocks various sport clothes, shoes,
and sport equipment, such as squash and tennis rackets. Kroko-Fit also has a restaurant that
serves drinks and healthy food. In addition to all these facilities, Kroko-Fit provides
racquet stringing service, shoe hire for the bowling lanes, and personal coaching.
The owners are not involved in the day to day operations and hired two people that can be
considered as the management of Kroko-Fit. The center employs 6 fulltime receptionists
and 2 technicians who maintain the center’s facilities. In addition, Kroko-Fit has contracts
with 4 casual tennis coaches and 2 squash coaches who can be booked through the main reception. Also, Kroko-Fit employs 5 fulltime hospitality staff, who prepare and serve food
and drinks in the restaurant and 3 casual staff for the Kroko-Shop.
The use of the swimming pool and the gym are on membership basis. Members pay either
a one-off annual fee in January every year or pay a slightly higher fee every three or six
months. The rent of tennis and squash courts as well as for bowling lane is based on an
hourly rate. These rents and any other services, such as stringing, private lessons, shoe hire
and any purchase from the shop and restaurant are either paid in cash or a bill is sent at the
end of each month to the clients.
Currently, the center runs an excel spreadsheet for any booking systems with one hour
booking slots from 6am to 9pm. Once a booking is made for a court or a bowling lane, the
customer’s details are entered. Separate spreadsheets are kept for the tennis and the squash
courts and the bowling center. Changes to the bookings are frequently made and anybody
of Kroko-Fit’s staff who answers the phone or talks with a customer undertakes the
changes.
A paper file is maintained for each member recording their personal details and also
monthly use of the courts, the bowling center, stringing services, private lessons, restaurant
items, and purchases of items from the Kroko-Shop. Company policy dictates that private
lessons with a coach are on a one-on-one basis. Furthermore, members are allowed to
bring up to two guests per year to the center.
Kroko-Fits insurance requires that all people present in the club are known to the
management, hence, there is a paper-and-pencil system of signing in guests. Their name is
recorded against that of the member.
The restaurant orders food ingredients and drinks from a local whole seller. While the 5
staff members in the restaurant are full time, during summer holidays and other busy times,
casual staff is hired as well.
In recent months, especially during peak seasons, such as long weekends and holidays,
Kroko-Fit experienced a number of problems about which customers complained to the
management:
• Tennis courts were booked by customers who did not show up
• Customers arrived with a booking number but there was no court available
• Shoes rented for the bowling were supposed to be available in the shoe racks but,
sometimes, they were not
• Double booking of tennis and squash coaches
• Errors in monthly membership fee bills, especially when customers paused for some
time
• Food and drinks were not billed correctly
• Customers had to wait long until they were served by the reception staff or waitress in
the restaurant
In addition to addressing these problems, the management of Kroko-Fit wishes that the
new system can be used to introduce some innovations in servicing the customers but
should not involve any significant additional investment. As an expert in IS, you believe
that Kroko-Fit would gain the most benefit by automating parts of the current manual
system initially mentioned by the management. Note: Kroko-Fit is currently running the
MYOB accounting system to manage their normal everyday accounting functions.
Note: During designing the system, you may make some assumptions/add information to
enable you to complete the design. Please put the additional information/assumption in the
final report.
UML Portfolio
All UML models MUST be created with Enterprise Architect (EA) and each diagram must
be exported as an image and pasted into a Word document that MUST be submitted as
well.
The word document needs to include an overview page that must contain a table of
contents with meaningful headings. For example, “Activity Diagram 1 – Hiring a tennis
court”. In addition, each diagram may have assumptions underneath if needed. It is
recommendable approximately 200 words but can be less or more. Also, it is desirable the
use of bullet points. For example, “In order to improve the payment methods credit card
transactions were added “. Furthermore, the word document must have the pages numbered
and the diagrams must have a readable font size.
1. Two Use Case Diagrams
Each use case diagram should have 3 different actors, and 10 top level use cases and
includes multiple include/extend relationships.
2. Two Activity Diagrams
Activity diagrams should show a step-by-step logic of two different use cases. Each
aactivity diagram should have 10 steps (activities). You must have multiple split/fork, join
bars and various decision activities.
3. Two System Sequence Diagrams
Each system sequence diagram should include 1 domain object that interact with the actor
in a complex sequence of interactions (10 input messages) where the order of these
interactions is very important for achieving the goal. You should also include in your
system sequence diagrams message notations, multiple examples of loop frames, opt frames
and alt frames.
4. Two Domain Model Class Diagrams
Each class diagram shall include 10 domain classes, following UML notation for
multiplicity, including multiple instances of generalization/specialization, multiple cases of
whole-part relationships (i.e., aggregation, composition), and at least one association class.
Please note that each model must represent the system from a different aspect point.
5. Two State Machine Diagrams
Each state machine diagram shall have 5 different states, with various transitions/paths,
various transition statements, multiple composite states.
