Grasp-It is exactly what it says it is: a tool for making knowledge easier to grasp.

"Grasp-it does indeed seem to me to offer an eminently sensible tool to aid analysts, decision-makers and (crucially) other interested parties to get a better grasp of the key drivers, loose ends and open implications in contending understandings of complex and uncertain policy problems".
