Based on the examination of the papers, an introductory calculation is created, which is as well a preliminary project of the online app. It is an estimate showing the quantity of expenditures to be incurred to project the app. Then, the design spec is created. It contains a summary of all parts and functionality, connections between application elements, mathematical formulas, info for reports. 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. After satisfying finishing of tests and approval of the whole project, the application is introduced on the client’s server and tests are repeated.
If everything operates properly, the software is implemented in the customer’s firm. As far as Polish custom software market is regarded, Objectivity Poland (from Wroclaw) is the most considered enterprise, as well among foreigner customers.
