Disruption

Consulting:

"It has always involved sending smart outsiders into organizations for a finite period of time and asking them to recommend solutions for the most difficult problems confronting their clients."

But today the consulting industry is undergoing tremendous change.  It's a disruption that other professional services should heed - namely, management and leadership training, and professional development.

What does the disruption look like?  Technology

"One of the most intriguing of these is McKinsey Solutions, software and technology-based analytics and tools that can be embedded at a client, providing ongoing engagement outside the traditional project-based model."
