Case Study: Auckland EZ hotel
Auckland EZ hotel located near Britomart is a 3-star hotel with 10 floors and each floor has 20
rooms. The management of the hotel has hired your company (BBC Software Ltd) to develop an
attendance and payroll management system. This software takes attendance of their staff member,
help the payroll department to calculate the number hours worked, leaves and takes into account
other parameters that might be necessary for deciding the pay made to an employee.
Security is of utmost concern to the hotel and they would like to have different access level for
different employee roles. The different employee roles are as follows –
• A hotel manager who oversees the functioning of the entire hotel from all aspects including
payroll and attendance
• Two receptionists who deal with reservation, check-in, check-out, scheduling of
housekeeping and room service
• One accountant dealing with the finances of the hotel like payroll
• Twenty housekeeping staff will only use the system to register their attendance
• One chef and ten kitchen and restaurant staff
The employees can perform the following actions – apply for leave and choose to work in a
particular shift. The hotel has three shifts – morning shift, evening shift and night shift. Additionally,
the manager can assign shifts or apply for leave on behalf of any employee. An employee not on
leave must be allocated to one and only one of the three kinds of shift in one day. Each shift must
at least have one employee. The hotel has the following work zones- rooms, restaurant, lounge and
toilet. For each shift (i.e. morning, evening or night), there must be an allocation for each of the
work zones. Every working employee must be allocated to one and only work zone in his or her
shift. Each work zone must have at least one employee.
The hotel is also concerned about the safety of their data and would like to have policies and
strategies in place to protect the integrity and safety of their data.
Write a report to cover the following tasks. Use APA referencing.
Task 1: Requirement Gathering and Analysis (Total 40 Marks)
Your company BBC Software Ltd being a start-up has a team of 7 software professionals excluding
the management. Keeping the project and your company structure in mind answer the following:
a. From a security perspective, identify the two types of requirements, with each type
having three (3) examples for this project. (5 Marks)
b. Keeping in mind the importance given to security by the hotel, make a comparison
between four (4) software development methodologies and choose an appropriate
methodology that is suitable for this project clearly justifying your choice. (10 Marks)
c. Identify and explain five threats to the hotel’s business that need to be considered
for the success of this system. (10 Marks)
d. Write down three elements of risk with two examples each that relate to the project’s
scenario. (9 Marks)
Task 2: System Design (Total 60 Marks)
Base on the requirement gathered in Task 1, answer the following:
a. Draw a Use Case Diagram that highlights the security related interactions of the
system amongst other interactions. (10 Marks)
b. Keeping the case study in mind draw a UML Class Diagram focussing on the different
access levels for each employee type. The diagram must contain the following –
employee first name and last name, ID no, telephone no, address, date(s) present,
date(s) on leave, hotel work zone and shift allocated”. (10 Marks)
c. Since physical security is an important aspect of the security Auckland EZ hotel is
highly concerned about each employee’s entry and exit from the building. To help
develop such a secure system, map out a State Transition Network (STN) for the daily
functioning of the attendance management part of the software. To scope the STN
use the following assumptions
1. The starting state is when the employee enters the company first and the finish state is when
the employee leaves finally for the day.
2. The attendance system is electronic and the employees have to tap their card on the card
reader to register their entry and exit from the company.
3. Once the employee taps, an entry is made in a database table, this entry can be called
‘Employee In’
4. If the employee taps a second time the database entry is ‘Employee Out’.
5. An employee can tap in and out multiple times during the work hours of 9 am to 5 pm. The
final exit for the day is considered at 5pm and total hours worked is calculated from the first
tap to the last tap before or at 5pm.
6. If an employee has a gap of more than 1 hr between a tap in and out, they are reported to the
HR
Comment and justify the STN (10 Marks)
