OPEN VO QUESTIONS
SHOULD CAN VOs EMULATE PROBLEM SOLVING ENV. ?
HOW CAN COMPUTE BUSINESS MODELS BE ADAPTED
TO MAKE BEST USE OF VOs ?
WHERE DO VOs NOT MAKE SENSE ?
WHAT IS THE REAL COST OF OPERATING VOs ?
CAN VOs HELP FOR MULDISCIPLINARY APPLICATIONS ?
HOW TO USE VOs FOR HIGH I/O APPLICATIONS ?
HOW TO DESIGN VOs FOR HIGH AVAILABILITY ?

CONCLUSION
PROVOCATIVE PESSIMISTIC

• ARE VOs NECESSARY ?

• CONCEPT FOR BEST USE PRACTICE FOR EXISTING GRIDS
  ?

• IF NOT, IS VOs ADDED-VALUE SO OBVIOUS ?

• IF NOT, WHERE HOW IS ADDED-VALUE ADDED ?

• WHERE DOES ADDED-VALUE MAKE SENSE ?
