Status comments should be included where appropriate. Verification considerations apply to all design modification. The entry criteria for the detailed systems design phase should match the exit criteria of the preceding General Design phase. A review and confirmation of the availability of the four General Design documents should be Undertaken. Special tasks to be performed - Detailed design 2.
Control always returns to the higher module.
For functional decomposition, examine each module to see if it contains only one self-evident function. For example, the module, process transaction, appears to consist of more than one function, so it is a candidate for decomposition. This decomposition was arrived are involved in processing a transaction. Specific task to be performed - Detailed design 3. Flow of control and data coupling.
