THE MATHS OF CHANGE, OR WHY 10+10+10=1000 The art of butterfly management. Obtaining radical organisational and cultural change without massive initiatives, impossible budgets and miserable processes Leandro Herrero Change in organisations is often approached as a massive initiative that often paralyzes life and has side-effects such as impairing or impacting on day-to-day productivity. In many organisations, assessment usually leads to the identification of a large number of issues that seem to require an equally large number of required actions through a change process that is long, painful and expensive. The author proposes an alternative model where a small number of levers can create significant change. Big radical change can be obtained not by a series of big radical initiatives but a small set of behavioural changes. Redirecting efforts to the identification of those levers and then putting energy behind them, can create sustainable change ... faster.
