as well as presenting the hierarchy, it is necessary to describe plans that define the possible ordering of activities. this is often thought of as a bad thing, but in this case it allows us to describe the optionally and alternative orderings within the task more clearly. he gets up and walks out to the shared printer area, heads for the printer in the far corner, and flicks through the pages that have accumulated there until he finds his letter.
he has a document template that is set up to print in the format appropriate for mailing labels, so he opens that and copies the information from his electronic address book to this new file. use these htas as a starting point for adapting the computer-based task so that it is easier for users. note that the design of search engines is a separate topic that is beyond the scope of this course! one of the hardest things to grasp about hta is how to construct a ‘good’ one.
task scenarios are fundamental records of the way users will actually carry out tasks involving the system to be designed. behind this technique is a very particular notion of a human task as being goal-directed, and where the goal of the task can be satisfied by the achievement of subsidiary goals that shape the activity involved in the task. the intention is to represent all tasks carried out by that class of users on one diagram. so far the nested list has only contained information about the static hierarchical relationship of tasks and subtasks, i.e., that a particular task is composed of particular subtasks.
whether represented as a nested list or diagram, the task analysis is always a work in progress. the task to be expanded in a separate diagram is indicated by a triangular tab, as 1.3 in the diagram above. it is likely to be useful if the complexity of the system and the number of scenarios required to capture it is relatively high. the conceptual approach to task analysis is addressed in a following section on the user conceptual model.
