Gains from standards activities
By Proposing Current technologies Grow/Focus
in/Stabilize the market Promote
constructive/effective competition New
technologies Clarify requirements, Quickly
create the market Future technologies Identify
the right direction By Contributing/supporting
Catch the future trends Develop company
networks/human networks Enhance the presence of
the company
14
Motivation of standards activities (Personal view)

Europe adjust / harmonize the market
(standards since 500 years ago) North America
lead / grow the market (standards as a
strategic marketing tool) Asia smell / know /
meet then / grow the global market
