volume_mute

Why must an interface specification be unambiguous during interface design?

So the feasibility study can be completed faster

So a component can be used without other components having to know how it is implemented, enabling concurrent development

So the marketing team can understand the system

So the database schema can be auto-generated

Design Outputs — Agile vs Critical Systems

1 pts

volume_mute

How do design outputs differ between agile methods and critical systems development?

For critical systems, detailed design documents must be produced; in agile methods, outputs may be represented in the code of the program rather than separate specification documents

Agile methods produce more documentation than critical systems

Both always produce the same level of design documentation regardless of method

Critical systems use no design documents; only agile methods produce them
