3 Appendix
3.1 Note
This appendix would not be in every use case. An appendix in a use case contains additional information
and artifact examples that might be use full in describing or understanding the usage scenario.

3.2 What is a use-case?
Use-cases are an unfolding story that describes the functions in a system and the usage paths through
them. They are essentially narrative descriptions with diagrams and example screens. Their purpose is to
describe in the simplest possible terms how the proposed system would be used.

Use-cases document the accomplishment of a single task by the user.

The use cases illustrate the functionality of the system in terms of the business processes the system is
being built to support. Use cases describe how it is envisioned users of the system (actors) would perform
tasks such as login, change settings, and enter a particular type of data.

3.3 Procedure for creating a use-case
The diagram below illustrates the process by which each use case is created. Basically it is an iterative
process where the business function required is considered from a number of different perspectives which
can be summarized as : CRUD-SPARP.

For example in a use case area like add a moodle site to the site list the analyst asks themselves how will I :

Create a Site (Create)

Review site details e.g. URL, Username – are there different views (Review)

Correct site details (Update)

Delete or Retire a site from use (Delete)

Search for a site on the site list (Search)

Print a sites details, a list of sites – are there different print styles (Print)

Archive or backup the site list e.g. send to dropbox (Archive)

Page 44 of 50

Generate a report on all sites e.g. how frequently are they accessed (Report)

Publish Export Import e.g. send the list to twitter, facebook or a website (Publish)

All of the above are self contained functionality within a module. But what are the reporting
requirements of this module in relation to other modules in the system – are there lookup to other
modules, what cross system reports are executed within this module or involve this module
(Report across system)

3.4 Use case structure
Each use case has the following narrative structure:

Page 47 of 50

Ref Heading Description

Actors Who performs the process described in the use case

Brief Description A description of the use case being specified with an overview diagram of the
process.

What is the goal of this use case, what is the objective of the user.

User Interface A wire frame diagram of the main screens and dialogs presented to the user as
they execute the use case. This is only used where appropriate. Its purpose is to
provide a visual aid to the reader as to the functionality available.

The user interface in this case is used to help explain the proposed functionality.
As user experience designers get involved the UI may change and even use cases
may disappear.

Including a mock up user interface can however drive out issues as to what data
needs to be displayed and if data is to be entered how it is validated. This
information then helps the design of the data model.

User Interface description A description of the user interface components and their functions

Trigger Event What event or action triggers this use case

Flow of Events

- Basic Flow A description of the main process where each step is referenced by a number. A
flow, state or sequence diagram may also be added to explain the process.

- Alternative Flow The basic flow describes how the process would be executed in 90% of the cases
i.e. where no error has occurred or where no business rule exceptions occur.

The alternate flows concern the business logic applied to a basic flow. For
instance the basic flow could be for to enter a URL, username and password.
Access to the moodle site is checked and the site is added.

Alternative flows may describe situations where there is an error in the input
data, the site cannot be reached etc.

Non-functional Requirements This section only contains content if it is specific to that particular use case not
the system as a whole.

- Usability A particular usability requirement. For instance command line functionality
required, quick key, must be able to select all and deselect a list, or deselect all
and select a list etc.

- Reliability A particular reliability requirement. For instance no site should be stored unless
connection to the site has been established at least once.

- Performance Minimum performance requirements. For instance the system should respond
report an issue with uploading within 10 seconds and ask if the user wants to

Page 48 of 50

continue or wait until they have a WiFi connection.

- Supportability What support/debug features need to be provided for this process.

Artefacts What is created, updated or deleted as a result of this business process

Pre-conditions This section outlines the Pre-conditions prior to the execution of the basic flow.
For instance there must be at least one valid site in the site list before the main
functionality of the moodle app can be accessed.

Assumptions may also be expressed here

Ref Heading Description

Post-Conditions How must the system or user interface be left after the execution of the basic
flow.

Authorization and Audit What roles are allowed access this functionality. Are there any confidentiality,
Requirements auditor logging requirements.

Business Rules Business rules referenced within the basic or alternative flows. For instance theire
may be rules as to what constitutes a valid password e.g. One capital letter, One
number, one non-numberalpha character where the password has not been used
before in the last 6 months..

Issues Any potential issues identified which may cause problems in the deployment of
this use case functionality.

Assumptions What assumptions have been made e.g. a wifi network connection is available as
opposed to an Edge or 3G connection

Constraints Are there scheduling constraints, legal constraints, accessibility constraints,
environment constraints

Data model and metadata Description of any data required or stored in relation to this usecase.
requirements
For a photo graph, audio recording or video there maybe metadata such as the
time takenrecorded, location of the recordingphotovideo.

The focus is a business description of the data rather than a technical description
of the data. For instance a use case may require a drop known list of participant
types – administrator, teacher, student, reviewer they would be mentioned here

If there was a particular XML format for publishing the site list to twitter or
facebook then the specification or definition would be mentioned here.
