David and Sara have established and managed their family business, a medical device company, for over 30 years.
David is the president of the company leading the sales team while Sara is functioning as a chief financial officer and chief operating officer.
The business has been great since its inception. Even though the employee turnover rate is higher than its competitors, the company has grown in the numbers of staff and sales steady until the past five years.
Both David and Sara have utilized a micromanagement approach to working with employees and have never accepted the need for change in order to adapt to the evolving environment.
They do not realize their micromanagement has hurt the company. To help revive the company, they decide to hire a management consultant.
As the hired management consultant, what leadership theory would you recommend to David and Sara? And why?
