The full form of CEO is Chief Executive Officer.
Understanding the Role of a CEO
A Chief Executive Officer (CEO) holds the highest-ranking executive position within a company or organization. They are responsible for making crucial decisions that affect the entire business. As noted by Investopedia (https://www.investopedia.com/terms/c/ceo.asp), CEOs are often tasked with company expansion and new product development, although specific responsibilities vary across companies. The CEO's role is often characterized by strategic planning and decision-making, such as deciding on expansion into new markets (https://resources.workable.com/hr-terms/ceo-vs-coo). They are the ultimate decision-maker, as defined by Merriam-Webster (https://www.merriam-webster.com/dictionary/CEO) as the executive with chief decision-making authority. Several sources, including Byju's (https://byjus.com/full-form/ceo-full-form/) and Naukri (https://www.naukri.com/career-advice/what-is-the-full-form-of-ceo-caid), confirm this definition.
While the term "CEO" is commonly associated with large corporations, it's important to note that the role can also exist in smaller organizations and even in non-profit settings. The responsibilities and scope of a CEO's work may differ depending on the size and nature of the organization. For instance, the context of "CEO" can even appear in a form such as the "GEF-7 Full-sized Project CEO Endorsement Request Form" (https://www.thegef.org/documents/gef-7-full-sized-project-ceo-endorsement-request-form), demonstrating that the abbreviation is used in diverse contexts. In some instances, as seen with the Chief Electoral Officer (https://ceomeghalaya.nic.in/abbrv.html), the abbreviation "CEO" may even represent a slightly different but related title.
