Application
This unit is relevant to those who work as user-interface designers and responsible for specifying the layout and style of the desired user interface. They may be developers working in the area of user-interface design and implementation.
The context of the unit applies to different types of user interfaces, such as command-line interfaces (CLI), graphical user interfaces (GUI), web user interfaces (WUI) and natural user interfaces (NUI).
Prerequisites
Not applicable.

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: design a fully functional UI in consultation with the user using the determined language create a prototype UI review the prototype with the user build the UI test that created UI is complete, consistent and functional. |
Context of and specific resources for assessment | Assessment must ensure access to: internet in order to use online tools available for prototyping and UI design integrated development environment (IDE) for the determined language specific tools and licenses are available depending on particular platform, such as Windows, Linux, Unix, Mac and Google Chrome appropriate learning and assessment support when required modified equipment 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: evaluation of candidate’s: UI prototype completed UI review of candidate’s UI documentation verbal or written questioning to determine candidate’s knowledge of: UI components prototyping methodology. |
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. |
Range Statement
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.
Gather requirements may include: | interviews observation questionnaires. |
Development language may include: | object-oriented language, such as: ASP.NET C++ Java JavaScript JSP NET (VB, C#) Python XHTML, DHTML and CSS. |
Prototyping tools may include: | commercial applications, such as: Adobe FireWorks CS4 Adobe Flash Catalyst Axure Balsamiq Mockups Microsoft Expression Blend MockupScreens open-source tools, such as: FluidIA Napkin Look & Feel Pencil Sketching web-based tool, such as: Hot Gloo Mockingbird. |
UI components may include: | common and basic controls, such as button, label, textbox, checkbox and combo box container controls data controls dialogs menus and toolbars controls printing controls. |
UI actions may include: | keyboard actions along with the key modifiers keyboard actions, such as key press, key release and key action mouse actions include moves, button presses, button releases and dragging use of emerging interactive surface technologies and the NUI. |
