I'm working on a case study. It involves a superintendent accepting bribes and kickbacks from a contractor with the School District, and embezzlement. The contractor made payments to numerous creditors on the superintendent's behalf, which included paying off his automobile loan, remodeling and improvements for his home, paying off his personal credit card, and paying for the college tuition of the superintendent's children. What are five most important practices to apply problem-solving skills to address this issue and concern within the organization?
