Accountants define internal controls as the most important item a business can focus on to improve quality and reduce risk within financial reporting. Business owners define internal controls as time consuming, expensive processes with limited rewards.
Adam is a nice, quiet employee who works day and night in his office. He never asks for help or causes any issues. Adam leaves the company and then you realize he had been stealing from the company for years and took full advantage of the lack of controls in place as he gained more and more responsibility and trust from management or owners.
