Whenever we have big plans, we all hope for success. We all hope that one day the plan will turn out to be as glamorous as we have envisioned it. That vision is the source of power and hope that carries us forward, or towards, the goal. For example, if you want to launch a new product line, you probably have a number in the back of your mind that will 'break even', and another number that you envision to mark the project a 'success', and yet another as 'blockbuster success'. But what happens when that project took on a life of it's own and it became 'success beyond your wildest dream'? Is it simply a case of laughing yourself to the bank?
Let's be honest, not everyone is Elon Musk launching a Tesla 3 tomorrow that secure more than 300,000 reservations in a week, that's incredible for a car, and I'm very interested to see how he will lead his company to deliver. On the other hand, I've personally witness a small business owner getting so much press and success that he simply couldn't handle it. In that case he didn't have a plan to rope in supportive resources to help him deliver what the press has drummed up. The response was so overwhelming to him that for a good period of time he just simply fail to perform, fail to deliver. In the end he was lucky to pull himself back together in the last minute and preventing his greatest success from becoming a career disaster.
So have a plan for project failure, and have a plan for project success. But I would challenge you to have a plan for 'success beyond your wildest dream'. It may be a limited quantity at launch time, it may be extra inventory. It may be on-demand scale-ability of servers and temp workforce help to fill orders. No matter what that might look like, you want to laugh yourself to the bank, not dig a hole to hide in when success knock.
