It's all too true that, where some organisations have sent someone to 'do digital', they've failed, not through lack of enterprise but because the mandate for change did not come from the top.  

Our experience of helping insurers achieve digital transformation in insurance claims, is a case in point.

Innovative executives, armed with bright ideas and great intentions hit a brick wall, simply because they end up tinkering, instead of being able to achieve wholesale change.

Once the organisation is fully signed up to digitalisation; it often drives benefits not anticipated at the outset.  If the C-suite is involved from the start, more will be achieved, as the green light is given for digitalisation to move into other areas of the business.
