Research from the legal IT people Peppermint suggests that lawyers are not very good at keeping in touch with their clients once a deal or piece of work is complete.  They lag behind accountants and management consultants. 

That doesn't surprise me.  The transactional nature of their work often means that as soon as one piece of work is completed it is straight on to something else.

Technology isn't going to resolve that problem (sorry Peppermint).  

Good old fashioned marketing practice, that creates opportunities for conversations, supported by technology, is what is needed.

And if the lawyers aren't capable of that, well that's what marketing teams are for.
