This article is about a range of techniques which involve people reporting on actions, thoughts or rationale. It’s not about writing technical reports, etc.
These techniques evolved independently, rather than as a systematic toolbox. However, in practice they complement each other neatly. The table below shows how they fit together.
|Time||Technique(s)||Main knowledge issues involved|
|Future||Scenarios||Knowing the unknowable|
|Present||Think-aloud||Short Term Memory/working memory|
||Active and passive biases in human memory|
This article describes how these techniques can be used systematically to identify and clarify clients’ requirements, with particular reference to legal and practical constraints.
