Assessing options. Generate certain criteria (financial, time, organisational precedent and workability) against which different courses of action can be rated. This helps to determine which approach is best.
Making the decision and informing people. Once a solution has been determined, it should be communicated clearly to all those responsible for implementing it or to those affected by it in order to counter any confusion.
Implementing the solution. Set a time frame for delivery and deadlines for each stage. After this, it is a matter of seeing that everything is done on time and that the inevitable glitches in the implementation process are overcome.
Verifying the decision. When the plan has been implemented, its effects can be monitored to see if they are what was desired, or whether they have resulted in other problems that will need solving.
