More than a simple sequence of steps, we think system design should be intended as a whole. From the initial system business idea with its conceptual design to the final commitment we believe that thinking as a whole, together with the complete sharing of customer goals and needs, will make the difference.

While the Business Idea is a typical customer job, all the other phases may be made by Skytechnology, with or without involving the customer; during the Conceptual Design a first decomposition of the system is done, selecting macro components like subsystems, abstract HW/SW components, communication network, presentation media, etc. The Analysis phase is devoted to the requirement specification, - covering all the functional/quality/safety aspects of the system/subsystem/component - to the make or buy analysis and, in specific cases, to the risk analysis. The next step is the System Architectural design, where the system is formally described in terms of HW/SW components (to buy or to develop), their interfaces and the way for validating them. During the Development phase specific FW and SW components (and sometimes specific HW boards) are built according to the requirement previously defined; verification is part of this phase. The System Integration is perhaps the most important phase: when all the components are available, either by means of COTS procurement or by development of validated components, the system becomes to be assembled - a component with its partner, then 3 components, a subsystem, 2 subsystems and, at the end, the entire system.

Now the system is ready to be installed: the final Commitment phase is then the moment when the Skytechnology team, together with the customer, validates the solution and is ready for an new opportunity.
