Task descriptions as functional requirements

The tasks and support approach uses task descriptions that specify what the user and computer shall accomplish together without being explicit about who performs which parts of a task. The requirement is simply to support the identified tasks. Stakeholders can easily validate and later verify such requirements. This approach is just as successful for product development and large-scale work restructuring as it is for buying commercial off-the-shelf products. Although the resulting requirements are of higher quality than traditional requirements, they are much faster to produce.
