Eliciting Requirements
QFD (Quality Function Deployments)
Normal requirements:
The objectives and goals that are stated for a product or system during meetings with the customer. If these requirements are present, the customer is satisfied.
Expected requirements:
These requirements are implicit to the product or system and may be so fundamental that the customer does not explicitly state them. Their absence will be a cause for significant dissatisfaction.
Exiting requirements:
These features go beyond the customer’s expectations and prove to be very satisfying when present.
