Effectiveness of software testing techniques in enterprise: a case study

The limitations of research.
One of the possible limitations of the investigation is the limited 
number of experts who are available for interviewing. The all come from different professional 
backgrounds, their level of experience is dependent on team, type of project implemented, and 
subordination level. Their domain of work might be slightly different because of highly nuanced
nature of each step of software development process. There are also differences in procedures which 
each of these experts execute in their teams. These factors might distort some information gathered 
from the experts during the interviews. We would like to stress out that the enterprise is dependant and 
relying on the professionals which it employs and data information gathered from the experts is only 
applicable to certain case scenario and should not be evaluated as transferable to other organizations at 
full scale. 
The second limitation arise from the instrument used for investigation. Informants were
provided with questionnaire which is included open and closed questions. Since the interview based

questions were provided in straight forward nature we did not had a chance to ask additional questions 
which could arise from the answers of the experts in a real time. However, after the answers were 
received we asked the interviewees to provide some additional information to some questions. 
Third limitation is related to the nature of quantitative questions. These were given to very few 
respondents. Since the population is low, it is impossible to generalize the results for broader 
population. 
The ethics of research. 
According to Miller (2012), it is essential to inform informants about 
research problem and purpose and use ethical elements. Regarding this, we provided the required 
information about research process, main goals, and research problem to our informants. All 
questionnaires were given to informants personally by email in order to ensure that no information 
sharing has been made between them and anonymity of each of them is not revealed. In addition, 
confidentiality principle is one of the most important which ensures that the information about 
enterprise processes, teams, and clients remain unrevealed. To achieve this principle and gain trust of 
informants, we gave other names to teams and informants. Enterprise name is not used in this research 
as well. Thus, our experts were informed about all process of empirical study and their anonymity 
were ensured.
