Elements and Performance Criteria

1. Design WML deck
   • Analyse existing hypertext markup language (HTML) page design and identify information to be accessible via hand-held device
   • Design deck logical structure, ensuring that deck size is kept within acceptable boundaries
   • Determine structure of content based on business needs and user requirements
   • Identify links between sets of cards
   • Design cards for user input or for the selection of more than one item
2. Create deck
   • Code each card in the deck, ensuring each card has an ID and a title
   • Create cards using language and practices compliant with the international WML standard
   • Use best practice coding standards in creating the deck
   • Avoid device specific features in creating the deck
3. Test deck
   • Test deck on multiple devices to ensure compatibility with as many hand-held devices as possible
   • Validate WML files by typing and submitting the uniform resource locator of the WML file or the WML validator
   • Ensure the and tasks select the correct card in the deck
   • Ensure the tested WML files meet the needs of the business client

Performance Evidence

Evidence of the ability to:

analyse existing parameters

design wireless markup language (WML) files that meet the business client's need

create the code using appropriate language and standards

test and validate compatibility and performance.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
