Fig. 2. What selection and evaluation actions were performed?

Fig. 3. When was the OTS component selected?

Second, we investigated the relationship between the two context variables with the selection and evaluation activities performed. Since possible answers on the selec- tion and evaluation activity variable are “yes”, “no”, or “do not know”, we treated the projects with “yes” and “no” answers as two independent samples and then compared the mean differences of the two context variables. For the project members’ familiar- ity variable, we used the Mann-Whitney test in SPSS 14.0 to compare their rank dif- ferences. Results, presented in Table 2, show that project members will search the internet for a possible candidate, if there is no proper or familiar candidate at hand.
