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
