HCD.28:4.4 - Select the material and service forms for those connections
Choose representation by the operation it must enable. A table can make two measured conditions comparable; a diagram can expose a relation lost in prose; an animation can show a change whose timing matters; a simulator can allow a consequential choice and informative response. A more elaborate medium is not automatically a better explanation.
Distinguish the subject account, its teaching companion, practice materials and service instructions. They may share a file or interface, but a change affects them differently. Keep the subject criterion identifiable so that a new example does not establish a rival rule. A useful compact reminder may accompany a developed explanation; it cannot carry an operation the explanation leaves unstated.
For a Guide or Slidement, the Learning Product practice supplies its applicable instructional and carrier construction. A complete course or mentoring service also needs programme, provider and delivery decisions; publishing a guide does not establish them. SYSE.2/.8 can receive the use, offer and provider questions; organization and operations owners receive changes to assignments, capability and service operation.
State what version of a case, answer basis or tool the task uses when a change would alter correctness or feedback. When the criterion changes, identify dependent examples, exercises, mentor guidance and interpretation of prior responses. When only access or timing changes, preserve unaffected subject content.
