Operating expenses (OPEX) are the day-to-day expenses a company incurs to keep their business operational. In OpEx, we define tools as proven techniques that help teams understand their processes and make better decisions on how to improve them. Examples include concepts as straightforward as project charters, meeting rules and brainstorming.

Well-run businesses strive to find examples of continuous improvements in the workplace. As these improvements increase the bottom line, managers look for methods to find a measurable gain that can serve as a foundation to future business decisions. Continuous improvements are favorable to stakeholders including potential investors, current investors and stockowners.
