Elements and Performance Criteria

  1. Determine specification of GUI
  2. Design GUI to specification
  3. Build GUI to specification
  4. Test GUI to meet specification

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 following is essential

Assessment must confirm the ability to design build and test a GUI

To demonstrate competency in this unit the person will require access to

Development environment

Context of and specific resources for assessment

Graphical user interfaces take commands from input devices and expect the underlying operating system to carry out a function

When using this competency in a workplace context building a GUI should be done with the best available tool for the selected platform eg Linux UNIX Windows Mac Some of the tools used can build a GUI for all of the above platforms and if this is important select an IDE capable of compiling for all of the above

A number of GUIs are available under open source licences and it may be appropriate to access source code to assist in design and understanding GUI development process

The breadth depth and complexity of knowledge and skills in this competency would cover a broad range of varied activities or application in a wider variety of contexts most of which are complex and nonroutine Leadership and guidance would be involved when organising activities of self and others as well as contributing to technical solutions of a nonroutine or contingency nature

Assessment must ensure

Performance of a broad range of skilled applications including the requirement to evaluate and analyse current practices develop new criteria and procedures for performing current practices and provision of some leadership and guidance to others in the application and planning of the skills would be characteristic

Applications may involve responsibility for and limited organisation of others

The scope and complexity of knowledge and skills is dependent on the tasks undertaken as part of compiling and running applications

Method of assessment

The purpose of this unit is to define the standard of performance to be achieved in the workplace In undertaking training and assessment activities related to this unit consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs Additional guidance on these and related matters is provided in ICA Section

The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1.

Competency in this unit should be assessed using summative assessment to ensure consistency of performance in a range of contexts This unit can be assessed either in the workplace or in a simulated environment However simulated activities must closely reflect the workplace to enable full demonstration of competency

Assessment will usually include observation of real or simulated work processes and procedures andor performance in a project context as well as questioning on underpinning knowledge and skills The questioning of team members supervisors subordinates peers and clients where appropriate may provide valuable input to the assessment process The interdependence of units for assessment purposes may vary with the particular project or scenario

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector workplace and job role is recommended

An individual demonstrating this competency would be able to

Demonstrate understanding of a broad knowledge base incorporating some theoretical concepts

Apply solutions to a defined range of unpredictable problems

Identify and apply skill and knowledge areas to a wide variety of contexts with depth in some areas

Identify analyse and evaluate information from a variety of sources

Take responsibility for own outputs in relation to specified quality standards

Take limited responsibility for the quantity and quality of the output of others

Maintain knowledge of industry products and services

Additionally an individual demonstrating this competency would be able to

Demonstrate a GUI in concept and compiled form

Use a development tool to assist GUI construction

Meet client specifications

Contribute to code in an open source GUI project

Apply solutions to a variety of predictable problems

Interpret available information and request clarification where needed

Take responsibility for outputs in work and learning
