A way for creating and using a theory of a project in designing of a software intensive system

The extremely low degree of success in designing the systems with software is a root reason for the finding of novelties in theoretical and practical foundations of software engineering. This paper focuses on building the project theories of a substantially evolutionary type that corresponds to the becoming of a project documentation. An offered way-of-working is based on the use of question-answering and precedent-oriented solving the project tasks.
