Conclusion

ContributionLesson 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

THANK YOU
