Spec is an app design that involves a price estimate for each part, which is the final estimation and the offer for application realization. After accepting the project, app is realized according to the spec and functional design. If the design allows for the partition of bigger portions, the software is introduced in stages. The application is put for trials in the development system. At this stage, modifications and adjustments are made due to the project.
