Data capture
- Synonyms and see also - requirements capture
Data capture is the acquisition of information. The information can come from different sources - documents, electronic media, interviews, conversations, and so on.
As used colloquially, the term is perhaps more relevant to the automatic acquisition of information via, for example, an online form or electronic survey, or by the electronic scanning (i.e. digitisation) of paper documents. But the term can be and is used widely to indicate the acquisition of information by any means.
Defaults
Defaults should be easy to "blow away:" Fields containing defaults should come up selected, so users can replace the default contents with new material quickly and easily.
Defaults should be "intelligent" and responsive.
Do not use the word "default" in an application or service. Replace with "Standard," "Use Customary Settings," "Restore Initial Settings," or some other more specific terms describing what will actually happen.
Definition
Definition is the name for the "documentation" phase of a production methodology where the solution created during Origination is written down.
In practise of course - in line with user-centred design techniques and agile methodological practise - Definition and Origination are tightly coupled, and do not follow each other in the rigidly sequential manner of a waterfall methodology.
Dendrogram
- Synonyms and see also - cluster analysis; sitemap; taxonomy; tree-structure
A dendrogram is a kind of tree-structure diagram often used to illustrate the arrangement of the clusters produced by a statistical clustering algorithm (such as cluster analysis).
In a dendrogram, the measure of similarity being illustrated - and therefore used by the clustering algorithm - is Euclidean distance.
Discovery
Discovery is the name for the first phase of a production methodology. It is essentially a research and requirements capture effort. It therefore will involve some or all of the usual data capture techniques and methods of analysis such as contextual inquiry, context of use analysis, the use of questionnaires and surveys, and so on.
Dwell time
The time a user lingers over or at a certain step of a task, e.g. the time that a user holds the pointer over a button or link, or the time spent viewing a piece of content.
