You have to write three things, the beginning, the middle and the end; exactly the same as if you were writing a book, in one page! The beginning describe the problem you faced, its impact on your entreprise, its the staff and the production. The description can be precise including the fallout on everybody and on the bottom line. At the end of the first part you are facing a wall, it seems very difficult get a positive result. The middle section show the begining of the transition, describe the event or touhgt who change your mindset and what you tried afterward. It might not be a miracle solution, but you had a hit and it changed the game. Now, the description follows the differents actors, their involvment, you tell how you reacted, how you directed the change (remember, it's all about you). The last part desribe the solution fully implanted or, for the brave at heart, how it completely fail. It is difficult for anyone to be involve with failure but remember, we are in business or leading organizations because someone did not saw, or failed to create what we propose now, with success. It is also important for any manager to know what works and what fails. If your description is interesting enough you will recieve feedback of others managers who want to exchange with you, who are probably in the same situation. This is a very positive proposition for anybody. So don't be shy, get help to write if you need it, but tell us about your biggest "coup d'état". We need your expertise.
