[ Requirements Acquisition, Interface Requirements Acquisition ]<br />
Dines Bjorner: 8th DRAFT: October 14, 2008<br />
invisible<br />
• This entails decisions on abstractions <strong>of</strong><br />
/home/db/tseb/kap3/kap3-1<br />
⋆ initial data input and refreshment,<br />
⋆ interactive computation <strong>of</strong> functions<br />
between the machine and the<br />
domain,<br />
⋆ “translation” <strong>of</strong> events in the domain<br />
into the machine, and<br />
⋆ interactive behaviours between the<br />
machine and the domain.<br />
• Again, each <strong>of</strong> these steps result in the input requirements acquisition document<br />
being futher annotated — as were the domain requirements acquisition<br />
documents.<br />
• Proper requirements modelling documents now take these annotated acquisition<br />
documents and rework them, “clean them up”, into proper requirements<br />
prescripton documents.<br />
