Application
This unit describes the skills and knowledge required to design, build, and test a user interface (UI) to specification, including command-line interfaces (CLI), graphical user interfaces (GUI), web user interfaces (WUI) and natural user interfaces (NUI).
It applies to individuals who work as user-interface designers, and are 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.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Build a prototype user interface (UI) | 1.1 Gather the requirements for the UI 1.2 Determine the application development language for writing the UI 1.3 Build a prototype, using the prototyping tools available in the determined language 1.4 Review the UI prototype with the client, and edit as required |
2. Design the UI | 2.1 Formulate the application content flow 2.2 Design the UI components 2.3 Define UI actions 2.4 Itemise UI events |
3. Build the UI | 3.1 Determine the appropriate language 3.2 Build the UI with the required functionality |
4. Test the UI | 4.1 Test the UI for overall functionality, according to requirements 4.2 Iterate the UI design, or build, until the test results meet requirements |
5. Document the UI and obtain client sign-off | 5.1 Document the user requirements 5.2 Document the UI 5.3 Obtain client sign-off to the completed UI |
Evidence of Performance
Evidence of the ability to:
design a fully functional user interface (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 the UI is complete, consistent and functional
document the user requirements, UI and client sign-off.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
apply a range of basic mathematical strategies
use object-oriented programming
use open-source development tools
describe the process of small-size application development.
Assessment Conditions
conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the programming and software development industry, and include access to:
the internet, to use the online tools available for prototyping and UI design
an integrated development environment (IDE) for the determined language
specific tools and licenses available, depending on the particular platform including:
Windows
Linux
Unix
Mac
Google Chrome.
Assessors must satisfy NVR/AQTF assessor requirements.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
Skill | Performance Criteria | Description |
Reading | 3.2 | Applies appropriate strategies in order to construct meaning from complex texts, when reading technical data |
Writing | 5.1-5.3 | Displays a knowledge of structure and layout, employing a broad vocabulary, grammatical structure and the conventions appropriate to text |
Numeracy | 2.2 | Selects from, and applies, an expanding range of mathematical and problem-solving strategies |
Navigate the world of work | 5.1-5.3 | Recognises and follows explicit, and implicit, protocols, and meets expectations associated with own role when documenting user requirements, and gaining sign-off |
Interact with others | 1.4 | Participates in complex formal and informal conversations relevant to own role, initiating and taking the lead where appropriate |
Get the work done | 1.1-1.4, 2.1-2.4, 3.1, 3.1, 4.1, 4.2 | Uses a combination of formal, logical planning processes, and an increasingly intuitive understanding of context, to identify relevant information and risks, identify and evaluate alternative strategies, and resources, when gathering requirements Uses systematic, analytical processes, setting goals, gathering relevant information, and identifying, and evaluating options against the agreed criteria Uses analytical processes to decide on a course of action, establishing the criteria for deciding between options Actively identifies systems, devices and applications with the potential to meet current and/or future needs Utilises a broad range of features within applications to improve personal productivity, optimising software functions |
