Make agile a practical reality.

We Make Agile Practical

The path to agility is seldom a straight line. We help you MAP™ it.

We Make Agile Practical

We deliver training but we do not think of ourselves as a training company. We deliver consulting but we do not think of ourselves as a consulting company. Instead, we make agile practical (MAP™) by providing training and consulting to individuals, teams and organizations.

Our trainer/coaches average over two decades of agile experience. They deliver:

  • Private agile training for organizations who want to train their staff.
  • Public agile training for everyone.
  • Consulting / coaching for organizations growing agile.

The path to agility is seldom a straight line. We help you MAP™ it.
