Appendix B: First-order structural model analysis.
We evaluated a first-order model with the three dimensions of information systems development success, customer satisfaction, process performance, and software functionality, as distinct constructs. The resulting structural model is presented in
Appendix B, Figure 1. For the sake of clarity, we only include significant paths in Appendix B, Figure 1. Effect sizes are reported
in Appendix B, Table 1. The results show that there is no direct significant effect of stand-up meetings and pair programming
on any of the success dimensions. Collective code ownership is positively correlated with customer satisfaction and software
functionality. Both the agility constructs, namely software team response extensiveness and efficiency, are significantly correlated with each of the success dimensions, but extensiveness does not significantly impact process performance. The effect
sizes from collective code ownership to customer satisfaction and from software team responsive extensiveness to customer
satisfaction and software team responsive efficiency are medium, and all other effects are small (see Appendix B, Table 1).
