All the world’s a stage
Would you expect the cast of a play to go on stage and perform without rehearsing first? Of course not! Why is it then that so many organisations write their recovery “script” then put it on the shelf without a thought for any form of rehearsal, yet expect it to work when the curtain goes up?
It is only through rehearsal that the players can learn their parts properly and that minor imperfections can be ironed out. If the script says “enter stage left” but all the action is taking place stage right, then the script should be amended before curtain call, not during the action.
And the more realistic you make your rehearsals, the more at ease the cast will be during the main event. So why not make a full dress rehearsal your aim.
