I have written business plans for all manner of industries: a coin operated jukebox company, airlines, travel companies, new product launches, and anti_aging product companies. It is not necessary to have a passion for the product or the company to write or develop a business plan. What you must have is a passion for aggregating information, getting involved with and understanding the service or product, and understanding the financials of the product or service. By financials I am not referring to having a CPA before you undertake the task, but rather understanding the presentation of the information and analysis/ numbers to support the activity being planned. Financials are important because they are the score card in the world of commerce.
The time of the year to huddle all of your business colleagues in a room to hash out the key initiatives for the upcoming year. The time to throw everything up on the wall and try to get everything done in the first quarter. "This will be the year that all plans will be met" is the battle cry! Every vision, idea and strategy gets bantered about _ shouts of "there are no bad ideas!" fill the air. The room is electric with visionaries exchanging ideas on how their idea solves all issues, yet year after year, it seems that plans never actually come to fruition.
