This work can lead to the process of software development is a way to increase both the effectiveness of teaching SE and the effectiveness of the software engineer’s work. We have used this system in the “Software Engineering” course labs at Varna. This new systems can able to draw the attention on both the use of software tools in all phases of software development on as well on the tools development. An open for future development package of software tools is developed for this case; its current structure is discussed in the paper.
