## 5 System Testing and Evaluation
### Evaluation: Qualitative Evaluation Instrument
#### 5.2.3 Statistical Analysis of the Result  
The participants' feedback was analyzed using the study evaluation instrument (questionnaires). This analysis assisted in explaining the most important aspects of our proposed system evaluation. It was mainly performed using the Statistical Package for the Social Sciences (SPSS) software. The study's results are discussed below. 1. The analysis of the pre-questionnaire  
Table 3 explains the analysis of the pre-questionnaire. Of the total participants, 54% had 15-20 years of experience, 27% had 5-10 years, and the percentage was equal for those with 1-5 and more than 20 years of experience, which was 9%. The participants' skills in using this type of application were 31% excellent, 54% good, 13% fair, and no one had no skills. Regarding the question about estimating the time taken to find a suitable donor using this type of application, their answers were 45% needed 3 h, 31% needed 6 h, 18% \begin{table}

Table 5: Demographic details of the participants. needed 1 day, and 4% needed more than that. Furthermore, for the question about the usage of such a system or application in work, the answers were 31% yes and 68% no. Finally, all the answers regarding whether the application would be used continuously were yes. 2. The analysis of the questionnaire  
The results of the study are discussed as follows, starting with an analysis of Satisfaction, followed by Efficiency, and, finally, the Effectiveness parameter. * Satisfaction  
This parameter measured the level of user acceptance, enjoyment, and ease of use of the system, and, to evaluate this parameter, four items were considered. The result of each item is shown in Table 7.  
Most responses agreed or completely agreed that the system was convenient and useful. Furthermore, many participants showed an excellent level of agreement that the system was easy to use and that no prior training was required to use it. This was mainly because the layout of the Web app page was uncomplicated and easy to navigate. Moreover, a large group of participants agreed that the donors should manage their data. This impacted the majority, who agreed that providing a mobile application would be a good idea. However, a few participants remained neutral because they argued that not all donors are qualified to manage their data.
