You should agree that spending money on creating the incorrect functionality is meaningless. Analysis of requirements before starting a new phase of development allows us to minimize the defects and to take into account the wishes of customers. Requirements analysis to implementation helps to think through possible changes and differences that may arise throughout the life cycle of the project. The team should agree with the customer all the business details that need to be implemented. Requirements analysis can also be performed using prototypes and models subject area.

After completing software development quality assurance work prior to the actual implementation, the development team receives a great starting point for your project or iteration of development. Making sure prior to the implementation that all concerned parties reached a consensus and each team member equally understands the problem, the customer and the user can be assured of receiving a quality product at the end of the development cycle.

Code analysis is one of the most effective methods of software development. It directly affects the reduction of the number of defects (allowing for mistakes in advance) and increasing the quality of code and design. This reduces the need for significant refactoring and cleanup in the next version.

The group can agree on the principles of coding and design, tailored to the project requirements and implementation details. These principles have to follow the whole group, and every time after the development of new functions of one or more members of the group (except the author) needs to analyze the new code with the aim of finding coding bugs and design.

This technique helps the group in many ways, including in improving the quality of code and design, as well as to minimize and prevent defects. In addition, it allows all group members to be aware of each other’s work, facilitating the flow of work and increases the competence of the group in various software components and features. Group members work together with the verification of the code quality and implementation of the design. They receive immediate feedback from their colleagues. There is a double benefit: improving the quality of code and growing competence of the group.

Methodology in-session testing that was created by James Bach split the load test into sessions, each of which solves its task (obtaining well-defined results expected from this session). Each session has a specific duration (20 to 40 minutes), and the tester should work continuously throughout the session.

The tester is placed for some time in a closed space test, which allows him to focus on finding defects in the software. The session is to run a set of test cases, but a tester can test in the free mode. Thus, in-session testing is a mixture of formal and innovative tests because it gives space to research and intuition – the tester is given the time and freedom of action to identify unusual defects or to delve into the specific details of the software.
