Reform introduces uncertainty as well as having the potential to redistribute resources from one group to another. This can mobilise powerful opposition of interest groups. In the case of public organisations, the more stable an environment the more difficulty it can be to effect change and therefore unsettling the status quo is a necessary first step to get change underway. The general public can make or break a reform. Efforts to inform the public of the benefits of a particular reform can provide a balance to counter the often vocal views of those with vested interests opposing change.
Communication also means listening.
Create a sense of urgency. Once started, move quickly and decisively. Review the strategy and processes used to bring about change. Integrate the lessons learned in future. Bring a reform effort to a deliberate close.
