Logical Analysis of Systems, Risks, Changes

Of all the major problems encountered in computing, the most difficult is the management of the systems and their development. Unlike any engineering or architectural drawings, the systems cannot be visibly represented as a model. Any building or machine can be shown as a set of drawings and as a three dimensional model, but the design and the build of the system cannot be seen, nor can it be represented on top of a desk. In the case of an architectural concept, the designer will draw the plans and will supervise and delegate the tasks to builders to construct in a fashion, as close to perfect logistics as possible. In modern computing, structured methodologies are used, where dataflow diagrams can be drawn, data can be modelled, and at the end of the logical phase, the system can be prototyped and programmed.
