And then of course there is the idea of delivering elements or extensions to a professional services through software. This is an increasingly common way services organisations can lock in the high value they create in consulting for ongoing client benefit. How many consulting projects create change, or knowledge that is as ephemeral as the project itself? Staff change, intellectual property is not institutionalised, the knowledge walks out the door. As evidence of this, you only need to be consulting in the same firm for a few years to find you are called on by clients to provide continuity from long-previous projects.  So enter the concept that professional service firms extend their offerings with tailored tools that enable clients to really walk the talk on new ways.  Great for clients - and great for the service providers for alternate revenue and stronger client relationships.
