Dependency modelling is an extremely useful technique. As the name suggests, it’s a way of mapping dependencies, showing where failure in one area can impact upon others. Its strengths are in its simplicity and its versatility. It can be used to highlight the dependencies in a whole host of situations, for instance within systems, processes or environments, between pieces of equipment, facilities or other assets. It can be used to show the dependencies associated with meeting a particular objective or even to map the dependencies across the business as a whole.
One advantage of a dependency model is that it defines what is to be achieved, what needs to be in place or done in order to achieve it and what those things depend upon. Doing this helps us to prioritise and to focus on particular areas of concern.
Dependency modelling helps us to :
Dependency modelling shifts the focus from thinking of all the bad things that might happen to considering what needs to go right and what we depend upon for that to happen.
An altogether more positive approach to risk management!

Acumen helped us to identify and document our dependencies and potential single points of failure in a format that is clear and easy to understand.
