Questions
POD’s: Other Methodologies
 Product Lifecycle Management (PLM)
- An product design and management software
- Primarily used in manufacturing industries
 Semantic Integration (KIF, PIF & PSL)
 Business Process Management (BPM)
- Heterogeneous process specification and
workflow management
- Multi-organizational process oriented
Future work: Map solutions within PLM and BPM to AEC design practice
