Along with the tools used in systems engineering, there are a few steps that need to be taken when developing a system. The second step is design, which involves the creation of two models. The construction model, or blueprint, models the system in terms of existing components and materials from which the system is to be constructed. The third step is realization, which involves the actual construction of the system according to the construction model. This step also requires that the newly constructed system be tested with respect to the functional model.
Systems engineering is an essential part of industrial engineering.
Much of what industrial engineers deal with is either systematized, or is in great need of a system to make a process more efficient. Systems engineering allows the industrial engineer to test various working systems and decide which one would work best for a certain process. Without it, the job of the industrial engineer would be extremely tedious and time-consuming. Overall, systems engineering makes the job of industrial engineer much easier.
