The process of System Engineering

System Engineering is a good way to satisfy all requirements’ stakeholders. Like you can see just above, the modeling represents the three parts and steps to carefully respect in order to succeed and to achieve the design of the system / service without delaying the project and raising the price needed to industrialize it.

Engineers collect the requirements of customers, translated into “Requirements Engineering” to generate databases of the whole requirements of the system. Thanks to “Need Analysis and Modelling”, the engineers collaborate with stakeholders by models whom reflect the customer’s requirements. All of this data supports the design. With this methodology, system’s architectures are generated and customer’s satisfaction is warranted.

The schema above shows the lifecycle of a product. It is on this modeling that engineers design a system.

Below is an INCOSE’s picture that represents the lifecycle of the system in details. The International Council on Systems Engineering (INCOSE) is a not-for-profit membership organization founded to develop and disseminate the interdisciplinary principles and practices that enable the realization of successful systems.

The V process model illustrated above has gained wide acceptance in the community standards. One of the key reasons for the choice of this model is that it illustrates some key SEP principles about the relationship of the early phases of project development to the results of the project. The following discussion will walk through each step in the process. As the discussion proceeds from one step to another, the steps, particularly on the left side of the V, will usually be iterative in nature.
