In every case the answer will be different because the question assumes a common profile. Each organisation will look for something different to reflect their needs and often their own shortcomings. What is important is that they display an honest culture and ethos that is embedded in the organisation and not a sales patter that purports to support partnering approaches.
The CRAFT MAP (maturity assessment programme) was developed to give a holistic profile of an organisation that can be monitored over time. Experience suggests that no organisation is perfect and in addressing weakness both partners improve.
