One of the keys to long term stability and sustainability is for an organisation to be growing leaders and future managers. Where do those talented individuals come from? Often times talented managers are in your department and are in your team already. The key is being able to spot the talent, challenge them and ultimately release them to show their skill.
- Praise and reward. This is true of every employee but especially so for the aspiring manager. If they make a mistake - so what? If they do well - excellent. One thing to be weary of is being hard or harsh towards someone who is giving it a go. Review the final outcomes and then give praise for the good things they have accomplished. Then find another project or assignment and start the growing cycle again.
