Assignment 1
Information System Description Framework Assignment

The Business Information Systems CC10 assignment involves using the Information Systems Description Framework to describe a relatively small and simple information system. The concepts involved in information systems and information systems description have been discussed in class in preparation for, and in the process of, completing this assignment.

This is an individual assignment out of 100 marks and it is worth 15% of your final mark in Business Information Systems CC10.

Learning Outcomes
This assignment is assessing your ability to demonstrate the following learning outcomes that you have been taught in the lectures or workshops and practiced in the workshops.
Students should be able to:

● Describe an information system
● Apply the information system description framework

As part of the learning outcomes above, students should be able to analyse an information system and provide:
1. General description
2. External description
3. Diagram representing the external view
4. Internal description
5. Diagram representing the internal view

First Step – Choosing Your Information System
You are required to choose your own information system to describe in the assignment. It is part of the assignment to understand what an information system is, and what would be an appropriate information system to choose – the choice is ultimately yours.

How to choose an information system?
If you cannot think of an information system to describe, it is recommended that you look around in your daily life, at home, at work, at Canning College or just about anywhere. If you look closely enough you will most likely see information systems in everything you do and everywhere you go. If you are still unable to choose an information system you can ask for suggestions and ideas (but again you need to make the final choice).

Once you have some ideas it is recommended that you sketch both the external diagram and the internal diagram – sketch the information system showing the inputs, outputs, and internal information processors and information stores and communication networks. This will become Stage 1 of your assignment, and feedback following your submission will allow you to proceed and complete the in task assessment (Stage 2).

Note: Your information system does not need to be exactly the same as a real world information system, or to describe all aspects of a real world system. You can simplify and reduce the size and complexity of the information system. You need to demonstrate being able to follow the information systems description framework and produce a description in the required format using the required tools, not for the largest or most complex and perfect description. Examples used in either the lecture or tutorials cannot be used eg library information system.

Constraints on your choice of Information System
It is required that the information system you choose has:
● At least two information processors
● At least two data stores

It is recommended that you:
● Do NOT choose an information system that you know nothing about or do not understand.
● Do NOT choose an information system that is too large (e.g. a whole organisation or department)
● Do NOT choose an information system that is too complex – you can simplify things to make it easier

And: If you are a repeating student you cannot use the information system from your previous assignment.

Format and Length
The format for your information system description should match that provided in the unit materials and the template provided, although you are allowed to add additional sections and information if you wish, you must at least provide the sections and content we have explained (i.e. the five sections matching the five steps and excluding the optional sections).

The information system description you provide needs to be precise enough and detailed enough so that someone could develop the information system and put it into operation. It also needs to be consistent from one section to the next.

As this is a semi-technical document it may contain both text in standard paragraph format, e.g. introductory paragraphs for each section, and text in point form, e.g. for specific item lists. In fact when describing groups of important lists of items (e.g. users, user’s functions, inputs, outputs, information processors, information stores, (stored information) these should almost always be in an itemised format. As well you should make sure you give a name and a brief description, and possibly an example, for each item.
For example:
1. Customer – an individual person who is registered to rent from the video store. The Customer uses the Video Store Information System to:
a. Rent Videos – to loan a particular video for a specified period of time
b. Return Videos – …
c. Other

2. Head Office Information System – …
The Head Office Information Systems uses the Video Store Information System to:
a. …
b. …

1. Amount – the amount of money paid for the video, e.g . $7.50
2. Name – the first and last name of the customer, e.g. John Smith 3. …

Information Processors
1. Store Clerk Information Processor – the clerk is the information processor who works in the store. The Store Clerk performs the following information processing:

Notice how everything is (relatively) clear and itemised so we can quickly and easily refer to user number (1.) or the Head Office Information System user …

Similarly, we can clearly see the names of the inputs and read the brief description to see, e.g. what the name refers to (i.e. is it the customer or the video or something else?). Examples are useful as well.

The diagrams need to be consistent with the textual descriptions (e.g. the same inputs and outputs). You do not need to include all the information from the textual description in the diagram because the diagrams are supposed to be summaries of the textual descriptions and give an overall view of an aspect of the information system.

In summary, the qualities of a well-written information systems description include:
1. It is precise in its description,
2. It is detailed enough,
3. It is consistent (i.e. the number and names of items are the same in different sections),
4. It is complete,
5. It uses numbered lists for important items rather than long paragraphs of text describing many items together,
6. Each important item (e.g. inputs, outputs, information processors, information stores, information stored) has a sensible name and a brief description (e.g. one or two sentences and perhaps an example, if relevant),
7. It has clear and consistent diagrams that summarise the textual description.

Plagiarism, Collusion and Academic Misconduct
This is an individual assignment. This means you cannot copy anyone else’s work, work closely with anyone else, or cheat in any other way (e.g. copying work from a textbook or previous submission).

Further Resources
Please carefully read the following resources to help you complete the assignment:
● Lecture 2 – What are IS and TI? – introduces information systems and the information systems description framework used in the assignment.
● Workshop 2 – What are IS and TI? – discusses information systems and practices information systems description.

Stage 1 (5%)
The first task involves you choosing an appropriate information system to describe. This task is a part of the assignment and you will be marked on your choice of an appropriate and sensible information system. This stage involves you working through the inputs and outputs for your information system, and thinking about what information processing and storing will be taking place.
Stage 2 (10%)
This will be completed in your tutorial class (Friday) under exam conditions. It is recommended that you have practiced writing this up. The written assessment will be based on the diagrams submitted in Stage 1, and will become part of your Stage 2 Assessment. No other notes will be permitted into the test.

BISCC10 The Information System Framework is a 5 step process and this exercise is built around the 2 diagrams. (Step 3 and Step 5)

The diagrams do not have to have much detail, because they are described in the other steps
(Step 2 for Step 3, and Step 4 for Step 5)
Note: The assignment will include the students in the first instance producing their diagrams and submitting. They will be marked and returned, and then when it is the written component of the assignment they will bring their diagrams into class, and complete the other 3 steps.
Students are encouraged to have a go, and bring their diagrams to class for checking, and general assistance/ advise/ etc.

1. Blank page (landscape) – One side for the External Diagram/ other side for Internal Diagram.
2. Draw a circle in the middle of the page (This represents the Information System and where the information processing will take place.
3. This is the External Diagram – label the top of the page
4. Inputs and outputs need to be labelled.
5. Inputs come in from the left hand side and are labelled Input Users (providing the information/ or data that will be processed and which will then be output information).
Arrows from each of these towards the circle
Voter/s (as input users) provide:
Election Official (as input users) provides:
Policy and Guidelines
Head Office (Electoral Commission)
Electoral Commission Information System
(This shows that an information system can be linked to other information systems – Not required for this task but augments understanding)
6. Outputs are listed on the right hand side and are labled as Output Users (listing the outcomes from the information that has been processed)
Arrows to each of these from the circle
Voter/s (as output users) obtain:
Knowledge that they have voted (no fine)
(For this example there is no tangible output, other than they know that they have had their names marked off on the registration list)
Election Official (as output users) provides:
Policy and Guidelines
(These are documents that may have been referred to during the day’s proceedings, but have not been modified – processed)
7. Name of information system in the centre of the circle with acronym (ELection Voting Information System (ELVIS)) – NB: Must have information system in the title, and should be clear what the information system is doing.

Other side of the paper
1. This is the External Diagram – label the top of the page
2. Draw a circle
3. This component of the task requires the inclusion of cubes and cylinders to represent the information processing and the storing.

There is a requirement for 2 information processors and 2 information stores.
There would be a link (not an arrow) between the information processing and the store. For example, I am processing these instructions and storing them on my USB.
4. The information processor (cube) needs to have the name of the person who is doing the information processing on it
5. The store (cylinder) needs to be labelled with what it is.
6. Network lines need to be labelled (network, etc) This one is “Direct Interaction” because the clerk is interacting directly with the registration book/ list.
