What is evidence-based consulting and why does it matter?

Evidence-based consulting, and the related area of evidence-informed training, are simply about applying proven principles to consultancy and training interventions. By following the simple principle of applying what works, the outcomes resulting from consultancy and training are faster, less expensive and more effective.

We find that, all too often, managers ignore sound evidence and rely on personal experience or the latest fads promoted by management gurus. Unfortunately for organisations and society in general, managerial decisions affect all of our lives.

Evidence for the effectiveness of evidence-based consulting

There is a range of scientific research suggesting that an evidence-based approach to decision-making is likely to increase their effectiveness. The human mind is prone to biases that impair the quality of the decisions we make, so anything we can do to reduce the damaging impact of this trait is very useful.

This is a brief summary of some of the reasons behind our chosen approach.
