Outside-In. A definition?

"Outside In is a way to focus an
organisation on doing one thing,
achieving one goal and doing it right.
By focusing the organisation on this one goal,
the unnecessary complexity of all other things
that do not contribute to this goal can be eliminated.

Outside Inners know that customers are the key
to achieving this goal."

Steve Towers & David Mottershead



Some organisations may avoid the term Outside-In
and use other terms such as 'customer centricity' or
'customer alignment'. But at their heart such approaches
fit this definition precisely.
