Major Consolidation in industry
SAP and Oracle are the two main players
Proprietary Interfaces
Created from customer-selected COTS modules
Open Source ERPs Emerging
SOA, Cloud Computing, Other Emerging Technologies
How will these affect ERPs and interfaces?

ERP Metrics
RICEW Objects Sizing Metric based on Reports, Interfaces, Conversions, Extensions, and Workflows
These tailor the COTS ERP to achieve customer objectivesCOTS modules are not included in RICEW Object count
A technical metric analogous to Function Points, Object Points, etc.
Requirements CountsSizing Metric based on complete requirements specification and documentation
Available earlier than RICEW Object definitionDepends on maturity of requirements development

Develop New ERP Parametric Tools
CERs based on metrics (to be presented at June SCEA)
Normalized Cost per RICEW ObjectNormalized Cost per Requirement
Ultimately would like to Calibrate SLIM Model with ERP Data
