Hello Guys,


So i have an assignment due soon, however i do not know how to begin it, i understand the theory but i do not know how to apply the knowledge. We have been given a case study, but i cant start it due to the fact i dont know how to identify the system users to write the user stories and begin creating the DataFlow diagrams. We use powerdesigner and i was wondering if anyone here friendly enough can give me a hand to start it ! 

Case study as : 

"Macquarie University Request Efficient Response Management System (MURMERS)[1]

The Office of Facilities Management (OFM) provides “environmentally sustainable, high quality facilities and services to our customers in a professional, courteous and cost effective manner which enhances the University's image of being a University of distinction” (http://www.ofm.mq.edu.au/). Within their responsibilities, OFM manages cleaning and maintenance; general space management including refurbishments and planning new spaces; preparation and distribution of information relating to campus maps, public transport and parking options; casual room bookings & room hire; class and room timetabling; campus safety and security and lost property; and, not least of all, sustainability.


To achieve their goals and fulfilling their role within the university, OFM must keep track of requests for services and ensure that they are dealt with in a timely manner. You have been asked to develop a system, to be known as Macquarie University Request Efficient Response Management System (MURMERS) that will allow requests for services to be efficiently handled. The system will need to keep track of who requested the service, the nature of the request, allocation of resources to respond to and/or carry out the request, when the service is due, estimates of time needed and any overdue services. MURMERS will need to provide reports such as a daily request list or an overdue request exception report and generate email/SMS request messages for urgent requests.


MURMERS will not replace other systems used by OFM such as the timetabling or room booking systems or university-wide systems such as HROnline (Human Resource Management/Payroll system). However, MURMERS will need to interface to some existing systems. For example, to determine which staff are available (i.e. not on leave) and assign them to handle a request, MURMERS will need to talk to HROnline.

[1] This problem statement is fictitious. Therefore, do not contact OFM to ask for further details.






Specify the requirements using user stories. Ensure you identify each of the users and provide at least 2 user stories for each user. Write user stories (As a <user>, I want <….>, [so that …..]




  • Draw a Context diagram (level 0 Data Flow Diagram) which depicts data flows, the system scope and entities. (1 page) (1 mark)
  • Outline the system you envisage (that is, how will the software relate to other parts of the system such as people, hardware, processes/work activities and data) and other systems in the organisation. Diagram/s may help depict your ideas. What level of management and decision-making is related to this system?  (1 page) (1.5 mark)

Hi MizzyMQU and welcome to our forums:



Its tough if you don't know where to start, and can't identify the service users from the information provided. however I guess you don't need me to tell you that!


Here are two thoughts for your consideration:


1 Maybe you missed something when reading the notes?  Read them again and make a note of any potential service users that you can identify and see if that helps.


2 If you are genuinely stuck, then it probably indicates that you missed some important "elements of understanding" in your studies leading up to this assignment and it would be wise therefore to contact your tutor and request further direction so that you are absolutely clear on what is required.


Good luck and we hope you do well.
