Solving your problems with you
Inspiration.
An inspiring message delivered by an unfamiliar voice can supplement your approach and bear extra fruit.
Affirmation.
An external pair of eyes may be what you need to identify an issue and kick start improvement.
Capacity.
If you know your issue but lack the staff capacity to address it, a fixed term collaboration could be the answer.
Growth.
Every individual can get better with the right blend of support and challenge. An external stimulus could be key.
