Effectiveness of software testing techniques in enterprise: a case study

Results Analysis of the Effectiveness of Software Testing Techniques 
In the beginning of questionnaire (see Annex 5, page 75) experts were asked to specify the exact 
number of years that shows their experience in a software testing field. During the selection of experts 
by criteria, the list of QA test specialists were provided by Company. Only general information about 
overall experience in Company and their education were seen. In order to get more detailed 
information about the work experience, in the beginning of questionnaire (see Appendix , page ) we 
asked the experts to specify the exact number of years of their overall experience as test specialist as 
well. The most experienced expert in software testing field is Expert E: overall experience is 7 years 
and 4 of them - in our surveyed Company as a QA test lead. The position QA Test lead shows the 
highest competence of tester. It includes the advanced testing skills using different testing techniques, 
managing and improving test process. Especially, the technical knowledge on automated testing and 
software domain are highlighted. In addition, QA test lead manages his own QA team and makes 
decisions together with project manager which is responsible for all processes of software 
development. The Expert A has also a significant experience on testing (5 years), however only 1 year 
as a part of our Company. Other experts have quite similar experience in Company and overall. 
According Company regulations, the adoption process for new hired testers are about 1 year. Thus, all 
of our experts have completed this period and it can be assumed that they have enough knowledge on 
software domain and processes used in SDLC at this Company.
Furthermore, in order to answer the first question of our research we need to identify the main 
techniques used for QA testing in R&D teams, we need to separate techniques used by testers and 
developers: testing types and static analysis respectively. First of all, we asked the question "
What 
types of testing techniques are used in your team?". 
The general trends are illustrated in a chart below 
(see Figure 6, page 52).
