The extra level is not a hindrance

It is a better representation because the structure is presented more clearly. This feature often appears in divisions and is one of the most powerful ways of explaining functions. B.2.3.2 Linking (combining) arrows Arrows and blocks should have the appropriate level of abstraction in the diagram. This can be achieved in two ways: Combine arrows that are related to the same source and destination under one more general label and make one arrow. Rename some blocks (using Split and Clustering) to better distribute sub-functions and re-label the newly created arrows.

Rarely does an excess of arrows indicate an error. Perhaps because argentina whatsapp number data they are precise and carefully applied. But it is always true that an excess of arrows obscures the message. The ability of the consumer to correctly evaluate what is presented should determine the number of arrows used. B.2.3.3 Proposal for changes to the context A more detailed view when constructing a new diagram may reveal errors or omissions in the parent diagram. Parent modification is a natural and expected event. When creating an arrow structure, the rule is “” if there is any doubt about whether a function block needs an arrow, leave it - later detailing will reveal whether the arrow is really needed.

” This is the point at which such questions are resolved as they arise, rather than by early reasoning. Changes to a parent diagram can vary in complexity. If a change is adapted by revising only the parent itself, it is simpler than a revision that affects more distant diagrams. When proposing a change, think it through carefully and estimate the complexity. Replacing simple changes with complex ones can harm the quality of the decomposition. When the correction is complete, check all boundary connections to ensure that the ICOM codes are displayed correctly. When making changes, inform other authors working on the diagram.
