On the disadvantage side, some equally significant issues exist. First and foremost, the executive team is usually small, sometimes only one person. This executive, or entrepreneur, may have always operated the firm from his or her own instincts and sees little use in a more formalized procedure. Second, information and data to prepare an external and internal analysis may be limited, id they exist. Third, key employees usually have gained their skill through experience rather than with the use of systematic procedures, and resistance to change may develop. Other problems may include the constraint of limited resources and the issue of company ownership.
