Elements and Performance Criteria

1. Determine specification of GUI
   • Review GUI requirements
   • Review organisational standards for GUI
   • Determine the back-end for interfacing with the GUI
   • Determine the functionality of the GUI, including back-end interface
   • Determine the application development language for writing the GUI
   • Determine type and level of documentation required
2. Design GUI to specification
   • Design the GUI incorporating the required functionality
   • 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
   • Test GUI for overall functionality according to requirements
   • Iterate GUI design or build until test results meet requirements
   • Produce technical documentation for the GUI

Evidence Required

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 candidates 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 nonEnglish speaking background may need additional support In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge
