ProblemsInternal
Different goals for different team members • Individual performance rather then teamwork
Culture differences • Different way of working
Communication problems • Misunderstanding
3/26/2003 Project Wireless Vietnam 18
Problems (cont)
External Hierachical level at MoST
• bureaucracy• decisions are made beyond our influence and
knowledge Lack of trust and believe in us
• loosing motivation Budget approved too late
• lack of time for testing equipment
3/26/2003 Project Wireless Vietnam 19
RisksNo access to highest point or stakeholder’s building and
infrastructure
Radio design has to be redone
Project delay and goals may not be achieved
Plan B: implementation only in test environment
3/26/2003 Project Wireless Vietnam 20
Benefits
Learn about new wireless technologiesTheoretical and practical, hand-on
experiencesInvolved in an international project that
goes beyond countries’ bordersUnderstanding different culture and way of
working

SummaryWhat are we doing? Provide wireless broadband access in Hanoi
Where are we now? Wireless technologies survey Implementation plan Ordered equipment
Where are we going? Implementation of the two pilot sites Documentation and Training for stakeholders and staff at MoST
What are we expecting? Learn about wireless technologies Gaining international experience Discover other cultures
