The important thing is to realise that the clients get maximum value when someone can help them to clarify to themselves as to what they are really looking for. The vagary and fuzziness in trying to grasp 'what do I need' is an area of discomfort for every client. It is in the interest of consultants and IT professionals that they develop genuine empathy and good 'enquiry' skills. Acquire a continually learning mindset. Shed their patronising approach.
Every implementation is a learning experience.
Every client is a Guru.
