The wise Nigel Thurlow posted the following on LinkedIn –
A consultant should never implement solutions or attempt to fix anything. In most cases they’ll simply create thrash and often make things worse.
They should instead light the way and teach others to “learn to see”. Once others are able to see the consultant can guide them on contextually relevant tools, techniques, methods, and approaches.
Hint: you should be an expert generalist and possess deep knowledge beyond frameworks. People solve problems, not frameworks.
Teach others how to fish. Help them see and solve their own challenges. Trying to fix companies will only result in frustration for both sides.
Caveat: leaders (the ones with big job titles) must be engaged and participatory otherwise the best that can be hoped for is a short-term placebo effect.
