This unit applies to programmers in a variety of fields who are required to develop the system’s graphical interface with users.
GUIs take commands from input devices and expect the underlying operating system (OS) to carry out a function.
Not applicable.
1. Determine specification of GUI | 1.1 Review GUI requirements 1.2 Review organisational standards for GUI 1.3 Determine the back-end for interfacing with the GUI 1.4 Determine the functionality of the GUI, including back-end interface 1.5 Determine the application development language for writing the GUI 1.6 Determine type and level of documentation required |
2. Design GUI to specification | 2.1 Design the GUI incorporating the required functionality 2.2 Document design outcomes |
3. Build GUI to specification | 3.1 Build the GUI with the required functionality in the determined language, using the toolkit's classes or widgets, containers and other pertinent features |
4. Test and document GUI to meet specification | 4.1 Test GUI for overall functionality according to requirements 4.2 Iterate GUI design or build until test results meet requirements 4.3 Produce technical documentation for the GUI |

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the ability to: build a GUI to requirements demonstrate a GUI in concept and compiled form, using a development tool to assist GUI construction provide appropriate documentation. |
Context of and specific resources for assessment | Assessment must ensure access to: GUI requirements organisational standards development environment. Where applicable, physical resources should include equipment modified for people with special needs. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: verbal or written questioning to assess candidate’s knowledge of programming concepts and system properties evaluation of GUI completed by candidate review of documentation produced by candidate for GUI. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Requirements may include: | business network people in the organisation system. |
Standards may include: | industry recommendations organisational standards. |
Application development language may include: | Codemesh Eclipse (open source) EMACS EPP eXtensible pre-processor kit GTK2 Java 2 SDK Java Runner JBuilder 3.5, Visual Age 3.0 Netscape Directory SDK for Java: Source Code, Borland Enterprise Studio for Java QT and KDevelop Visual Basic Visual C++ Visual J++. |
Documentation may include: | audit trails client training International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and Australian Standards (AS) standards maintaining equipment inventory naming standards project management templates and report writing satisfaction reports version control. |
