There are number of reasons, often mixed together, that I have witnessed or indeed been guilty of myself, which hinder one's ability to seek assistance. These include (in no particular order):
Pride: Most often coupled with Arrogance, Pride seems to be substituted for intelligent decision making, by those whose opinions of themselves are traditionally front and centre of all others. Pride is not only the domain of arrogant CEO's or established business owners, but can be witnessed existing in countless business schools where the word hubris is confused with a type of flora by the newly minted alumni. Trust me on this one, I have an MBA :)
Stubbornness: I remember a particular incident with a very wealthy business owner who was interested in fixing his business. It was a great start but when it came to actually applying the medicine, he dug his heals in for no other reason than we were tampering with a particular part of his business that was his passion. Even applying a fact based approach did not help. Fixing the part of the business where his head went before his heart was no issue. But fixing the part of the business which was lead by his heart was a no go zone.
Arrogance: "Smartest guys in the room", does not just apply to Enron (see Link). I have witnessed on a number occasions business owners or super smart financiers (sorry intelligence as measured by IQ), usually men,. say "Thanks but no thanks, we have it sorted.", "If it gets much worse we will call you but we think we have it covered" and my all time favourite, "We don't need F&#@ing help, we need sales." only for the primary creditors to call their preferred administrators a couple of months later to try claw as much of their money back as possible.
Weakness: This may relate to the topic of Fear in so much that the Manager, CEO, etc believes that by showing such weakness, their livelihood may be at stake.
Shame: I have spoken with a number of managers who talk of being "embarrassed" when consultants have been bought in (sometimes forced in buy external parties i.e. owners, creditors etc) to try improve the given business. This is particularly prevalent where business owners who have worked hard to build their business are often embarrassed by the given business predicament. In many such instances, to quote William Blake, “Shame is pride's cloak.”
So how do you fix it? A simple word, but seemingly difficult to execute in the modern corporate world:
Putting up the 'Help Wanted' sign is not easy. But decide how you want to make your mark. Is it as someone who instigated the fixing process or is it as someone who knew there was a problem but sat on their hands? 'Was proud with sore hands' would not exactly make a great epitaph.
