Around 16% of people in an organisation are change agents. About 50% of people are late adopters or laggards.
Similarly, around 13% of employees are engaged contributers in the workplace:
All the rest are compliant – disconnected from the purpose of their organisation, controlled by performance management and procedures, largely resistant to change.
An idle thought: though we’d all dearly love to be change agents and contributors, by definition, we can’t all be change agents; we can’t all be contributors.
Half the battle – actually, over 80% of the battle – may be recognising our place in the organisational picture.
arbitrary constant 
Hmmm I fear that you are getting this stuff from the ‘school for change agents’ – a dubious enterprise in my view. I get really irritated when we assume that everyone wants to be ‘change agents’. Imagine what a world would be like full change agents – there would be no permanence, no ‘just good enough’ – instead a nightmare of relentless enthusiasm. Seriously thought I think that for many people turning up to work – doing an ok job and going home again is a perfectly acceptable and reasonable option – it does not mean that they are disconnected or alienated – it just means that they have other things they want to do and that float their boat.
All the best – Mark
