CONCLUSION
Conclusion Conclusion
Contribution
Lesson learned
Contribution • Design a flood safe renovation of an existing building • Scheduling a construction • A rough cost estimation
Lesson Learned Common views • Different background makes some difficulties, but we think on the same line to finish the project. • Hard to participate because of being in the virtual team. • Work responsibility is not clear.
Different views • UW: lack of specific information about the project and knowledge • IIT: understand the India English problems and thank Will for his help • IIT: 7:00 AM is too early • IIT: hardware and Internet problems are challenges but it is getting better
