The C-suite, also known as the corporate "upper management," is the highest tier of executive-level members within a company and is comprised of a variety of positions. These high-level professionals are responsible for making key decisions and setting the overall strategic vision and direction of an organization. C-suite executives is considered the most powerful and influential people within a company.

The four most commonly known executives or "C-level" positions, are chief executive officer (CEO), chief financial officer (CFO), chief operating officer (COO), and chief information officer (CIO). The CEO oversees all aspects of a company, including the day-to-day operations. The CFO manages the financial operations and budget of the organization, develops long-term financial strategies and initiatives, and records financial data. The COO is responsible for the efficient management, operations and overall performance of the company. Finally, the CIO oversees the development and maintenance of all of the company's information systems, infrastructures, networks, databases, and technologies. They are also responsible for protecting the company's data and information.

C-suite execs often work closely with the board of directors and top-level managers within the company who support their efforts. The board of directors together with the c-suite executives usually makes the major decisions related to financial direction and budgeting, investments, personnel changes, acquisitions and mergers, and public relations decisions. Besides the board of directors, other members who may aid and support the decisions of the c-suite executives include the legal counsel, executive vice presidents, and the heads of each business unit.

Historically, there have been more men in C-suite positions than women, something that is now being addressed by various organizations. For example, the Ford Foundation has pledged millions towards programs that increase the number of women and minority executives in C-suite positions.

C-suite executives can also be highly compensated for their work. Since these positions come with an intense level of responsibility, they offer high salaries and bonuses. C-suite executives are currently among the highest-paid professionals, and salaries for CFOs, CTOs and CMOs range from $152,000 to over $369,000.

The position of the c-suite executive is rigorous and demanding job. They must balance their time between overseeing their departments and collaborating with other c-suite members. C-suite executives must have a comprehensive understanding from the financial and strategic aspects of the organization to its human resources and technology requirements. With the stakes of finances, personnel, legal considerations and competitive market always at hand, c-suite executives must exercise a high level of decision-making and leadership skills to be successful.
