Assignment overview:
This assignment aims to produce a requirements document that captures the functional and non-functional requirements for an information system that supports the current needs of the Mt Dandenong Bakery Sales and Ordering management system as described in the Case Study Description.
Your tasks:
Information system development projects incorporate several key milestones. This assignment will require you to complete
Milestone 1 - problem analysis which includes understanding the business in general, their challenges, current system issues/problems, key functional/nonfunctional requirements and limitations.
Milestone 2 - Data Modelling which uses some of the models of a Structured Approach, such as Event table, Data fragments, a context diagram, DFDs, ERD and DFD documentation to illustrate the current system features.
Case Description:
Mt Dandenong Bakery and Patisserie is a Bakery & Cafe located in Olinda, in the heart of the Dandenong Ranges.
The business was initially doing very well, but in the last couple of years, the business environment has become very tough. On the one hand, there is a need to reduce costs and increase efficiency, whilst on the other hand, their current practices are essentially manual intensive.
Dr. Thomas Waggoner is an information systems professor at the Swinburne university. When he waited in the bakery shop to pick up his order, the lengthy and unorganized approach to attending to customers presented Dr. Waggoner with an idea, which he shared with the owner of the bakery. He hopes to help the business become more efficient. He also foresaw opportunities to expand the business by opening another two outlets in other locations. Sarah, the owner of the bakery, was very excited about the possibilities, and they decided to meet later in the week to discuss the details.
Introduction:
- Why conduct system analysis and design for a business? (You should write a brief literature review on the topic of system analysis and design, why this is important, the development trends, what are some of the key aspects that should be considered, what are the roles of requirement analysis in the system analysis and design process?).
- Business or system analysts need to have a "big picture" view of any business and their information systems. You are required to list the major responsibilities which you should take on to help the business. What is your basic plan, where you start, what you do and what you want to achieve?
- The purpose of your work.
Business Background
- What is the business, and what does this business do? (A brief description of their current business operation, products and services. Please note that you should read the case description, understand it and provide a summary. You shouldn't copy the case description provided directly to your report. Max, 100 words.)
- What are some of the challenges (internal and external) that the business current faces and how they will impact on overall business future development?
- In your opinion, what are the three major problems which you consider are the most important for the business and explain why they are important. What are some of the opportunities when these problems are solved? How would the organisation be better off by solving this problem or taking up this opportunity? You are welcome to add on problems/issues which not currently listed, but which you consider are essential to address. You should provide reasoning.
- Clearly explain the current system's objectives and constraints. Please note: you need to read the case description to understand what the current system does.
Scope (Current system)
- A written statement of functional/non-functional requirements (you are required to list them all with a brief explanation for each of them).
- Discuss the techniques of identifying the use cases.
Documentation
o Complete at least THREE (3) key data flow descriptions (Logical data dictionaries)
o Data element descriptions (Physical data dictionaries, at least 1 of the key data entities)
o A brief description for each of the key processes (top-level processes in level 0 DFD) written in plain English
o Write at least ONE lower-level process description in structured English
The set of data flow diagrams should include:
- Identify 10 to 12 key events, please note that
o for each key function, you must have, at least one event link to it;
o 'cancellation' or 'updating' related events shouldn't be included in your list of events;
o You should have at least one state, and one temporal event included in your list of events.
You should create an event table to list all these identified events, and each event should be matched with a DFD Fragment.
- A Context Diagram: This must be for the entire Mt Dandenong Bakery Food Sales and Ordering Management System. You need to show relevant external agents together with data flows between the system and the external agents.
- A set of levelled data flow diagrams which includes:
1) Level 0 DFD which includes all top-level processes, key data stores, key data flows and key external entities.
2) At least 1 top-level process from this Level 0 DFD is decomposed to level 1 DFD.
You will be assessed on your application of data flow diagrams according to the following criteria:
o DFD syntax
o DFD data conservation (also commonly known as "balancing" or data consistency in some textbooks)
o Quality of names
o Logical, not physical discription
o Quality of modelling is more important than quantity
Consistency - not only should each view (data flow, process, data store) be accurate and readable, but also the views must be consistent with each other, so the whole analysis makes sense.
- An Entity Relationship Diagram (ERD): It should be a high-level data model (many to many relationships is acceptable in this unit).
