From the product to the platform insurmountable gap not so difficult just 4 steps

in the face of Google Gmail and various mobile devices on the mail application,
Microsoft Outlook retreat.
Microsoft is trying to inject new vitality into Outlook,
from simple email products to platforms,
allowing users to connect with many third party services such as Yelp,
and impressive notes.
Whether the leap from product to platform works,
not only for Microsoft,
but also for a growing number of companies around the product or platform,
is an extremely important issue.
It is not difficult to understand why such an approach is attractive.
Products generate only a single source of revenue,
and platforms generate a variety of sources of income (our definition of the platform is the intermediary between two or more different groups and allows them to communicate directly).
