Management of Change (MOC) ?

When plants run for sometime, engineers will find that something is not working as required or they may feel that something else can give better results or some problems will necessiate to modify flowsheet, etc. When shopfloor engineers and supervisors go for implementation of the proposed change, they think that they are doing the right thing to improve. However, the possibility of unexpected events because of the change are normally not studied or anticipated.
Further they think that involving safety department is a waste of time or their work will be delayed because of possible discussions. Therefore they carryout changes without following the established safety procedures. Sometimes, there works give the desired results and therefore makes them to think that they are in right direction ALWAYS. This will set in wrong notions, disregard for safety procedures and will set a bad example for the others to follow the same methods.
Ultimately, a day will come when something goes wrong and blame game starts. Safety department says they are not aware of the change and plant executives say that safety department is not doing its job of surveillance and monitoring. If people do unsafe jobs and then wait for others to point out, then nobody can help. Safety departments are for providing advise and also monitor to caution the mangements. However, if people do works by hiding the information, they are doing so at their own peril.
So, change management should first be applied to persons' attitudes and understanding of safety procedures and then established MOC in the system will be followed by these people with complete understanding and regard for system.
