The supervision organization will assist the owner to formulate the overall planning and technical scheme of the project, as well as the formulation of the equipment selection scheme; After information engineering enters the field construction stage, information engineering supervision will supervise the progress, quality, cost and contract of the whole project, which is similar to the work done by traditional construction project supervision institutions; After the acceptance of the project, the owner will often ask the supervision organization to continue to assist in formulating the operation management system of information facilities. Therefore, the business scope of information engineering supervision institutions goes far beyond the scope of construction supervision, and often needs to extend outward, covering the whole process of information engineering project establishment to trial operation.
