Effectiveness of software testing techniques in enterprise: a case study

Figure 7. The trends of static testing techniques used in R&D teams 
Prepared by author according to empirical research results. 
After the first research question is answered, we need to focus on problems that teams are facing 
with during software testing process. Such problems include not even processes related with testing 
activities, but external issues that can affect team work. For example, organizational decisions related 
with planning time and QA team capacity may affect whole SDLC. If QA team are not available to 
handle all issues, the quality of software becomes poor and the price of software increases for few 
reasons. Firstly, if defects are detected after product (software) is delivered to customer, customer 
should report about defect - it takes time for him and his satisfaction is low, since it cannot use the 
current functionality that he needs. Secondly, reported defect will go through management side in 
order to confirm the validity of it, and then to bug fixing stage. Thus, only one issue requires all team 
involvement and efforts that cost. So it is better to discover defects at earlier stages of SDLC when the 
cost of defects are relatively low comparing with previous example. To overcome this, we need to 
discover what are the main problems that delays software testing and decrease the quality. These 
questions are related with research questions starting from to 2 to 4. We will try to answer by experts 
insights and statistical documents content analysis. 
The sixth question of questionnaire 
"Prioritize the following issues of software testing that 
should be used more effective in your team. Start from the highest point that should be improved." 
uses 
the ranking scale which enables survey experts to rank a set of problematic issues from highest to 
lowest – most important to least important. The priorities are illustrated in a chart below (see Figure 8, 
page 54). The most problematic issues (1 place) that should be improved are as follows: Time, Test 
Techniques, Incident handling, Test design and Test Management (test goals, process). Further, 2 place 
is devoted for Test design, Time, Incident handling and Test Execution.
