Begin by asking: what is currently wrong with the business? The answer is likely sales, expenses, business organization, or all three.
Ideas for increasing sales might include new marketing campaigns, new types of ad campaigns like Googe Adwords and social media, streetfront advertising, flyers, direct mail, e-mail campaigns, and discount promotions.
Ideas for reducing costs might include outsourcing different business functions, renegotiating rent, reducing headcount, and keeping more precise track of amount of product served.
Business organization starts with the questions which functions need to be performed by the business, and who is best to perform each task?
