When it comes to strategic communication, I've always believed that organisations that drive the communication themselves are far more likely to achieve the best results.
While external agencies and consultancies can offer great ideas, great process and sometimes even extra legs in making whatever change is necessary happen, they're far less likely to make change stick by imposing solutions from the outside.
This seems to be borne out in the latest CiB Strategy Awards. Almost all have gone to in-house teams: the people who are closest to the issues their organisations face. I work regularly on change programmes, but always strive to hand the real running of such projects in-house as soon as possible. I know how I can influence and affect change - but my presence as an external supplier will never be as powerful as the buy-in and delivery from managers who will have to live with the changes long after I've moved on.
