- Cannot access system or data
- Poor project implementation
- Unrealistic expectations
- Poor training
- Failure to plan on how to maintain the GIS data
and operations - Project cost overrun
- Scope change, adding premature detail
57Conclusions
- When Starting a GIS
- Identify your objectives for the project
