This is interesting and even though we rarely think about law firms when we talk about innovation, intrapreneurship for law firms would be a great idea.  There are some firms who run an internal competition for innovation; I understand Eversheds is one of those firms, but more should seek innovation, especially differentiated innovation.  

We need to remember that the team on the ground, not the management team, see the day to day customer issues and they should be encouraged to use their knowledge and experience to help address them via innovation.
