What does it offer?
✓ Current usability (integration in BIM-?)
✓ A broader range of project types (school buildings, administrative buildings,….)
✓ No «absolute truth» – only a support of experts
Where are its limits?
✓ Quality-, time- and cost-oriented project management
✓ Project profiling as visual management tool
✓ Visualisation of priorities and room for action
✓ Documentation of qualitative aspects and experiences
✓ Support of decision making with client/ in juries/ ….
✓ Linkage with costs for improved early cost estimations
✓ Linkage with person-hours for improved fee calculation
✓ Integration in databases to improve usability
Potential…..?
