Some issues going forward
Lack of basic data literacy … statistics,
analytical thinking, data-driven thinking
(i.e., top management cannot understand the
depth and width of this new challenges)
Lack of teachers and training systems … too
much emphasis on pure data science
Lack of total business architects and
translators bridging data, actual business and
policy makers
Lack of alignment of data utilization policies
