Making Changes

Making some changes in the response plan is to be expected. If problems exist, then you should address them promptly. There are two routes to making changes, which depend on the nature of the problems that are experienced–replanning and redesigning:
•Replanning is the most common form of change resulting from a response. This will result from problems such as time delays, cost overruns, and system blockages. They require immediate decisions to be made to "tweak" the system to get the implementation back on track. They require you to revisit the original plan and work out how to make modifications to ensure the response is completed as expected. Indeed, this will be part of the normal process of response implementation, in which monitoring identifies problems you must address, which in turn results in replanning of the response so that implementation can continue.
•Redesigning involves more fundamental changes, but is far less common than replanning. This may be necessary if it becomes clear that a planned response is simply unworkable, or where there are negative outcomes that far outweigh the likely positive achievements. Under these circumstances, it may be necessary to halt the response implementation and return to the drawing board, selecting alternative interventions that might be more feasible⁄effective. This should not be viewed as a negative process. Indeed, it is more acceptable to accept that the response is not working and start the process again, than to ignore the response failure and continue with the implementation process regardless of whether it will resolve the
