Community Performance Development
Focus on the customer perspective - the only worthwhile metric is a happy client. Develop a shared language for those soft skills around Vision and Values - done by initiating discussion on the relevant topics (if needs be do some Process Mapping to look for areas of potential disagreement - use a third party if relationships are not good at this stage).
Once the interest is initiated use a coaching model to continue the conversation, broaden the shared vocabulary and foster further development. This creates ownership - which leads to the team doing the monitoring.
This style of 'managing' has implicit issues such as responsibility and ownership and is potentially less confrontational than many alternatives. It also relies on the energy of the team and not solely the manager. Thus it is more likely to be taken up by the team members, be internalised more readily and lead to higher standard outcomes. It is, in fact, a low cost leadership model (cost in terms of energy, effort, motivation and outcome rather than cash) and has a potential return which far outweighs the effort required to get into the appropriate mindset and initiate the discussion.
