CEO, COO, CMO, CIO, CTO, and so on and so forth. Leadership positions are filled with acronyms, that’s true. It is becoming increasingly common for companies around the world to use these English-language terms to refer to the positions their managers hold in the organization.
At Esade, we take a closer look at the meaning of these acronyms and list the responsibilities and competencies associated with a company’s main senior managers. In other words, the people who are among the C-Level or C-Suite management ranks.
What is a CEO?
Here we explain who we mean when we talk about a CEO, a term widely used in today’s business world, and their most important responsibilities.
Meaning
The CEO, also known as the Chief Executive Officer, is the person who is in charge of running the company. In other words, they have ultimate responsibility at the strategical and operational level. In Spanish speaking countries, they are known as director/a general, director ejecutivo/a or consejero/a delegado/a. In English, they are also called MD (Managing Director).
Functions
The CEO stands out for their strategic overview and they accurately define the company’s vision, mission, and objectives, such as future investments, diversification of products or services, possible acquisitions of other companies, and other matters related to the organizational culture, the creation of new processes, and other internal policies.
The CEO’s role is also to maintain relations with the organization’s shareholders and investors, as well as to identify and set priorities. Finally, the CEO also acts as a spokesperson, so they are usually the public face of the company.
What is a COO?
The acronym COO stands for: Chief Operating Officer. Broadly speaking, the COO is a senior manager of vital importance to organizations because they know better than anyone the optimal functioning of the organization and the phases of the product or service.
Meaning
The COO is the Operations Director and he reports directly to the company CEO. In fact, most of the time, the role of COO is likened to a process of preparation for the CEO role. This is why, it is usually the COO who takes over from the CEO when they are not available.
Functions
In general, the COO’s responsibility lies in overseeing the proper operation of all business systems, with a particular focus on those linked to the various stages of the product life cycle. They create the company’s operation policies and rules, as well as the various action protocols.
They control the company’s key resources, determine what products or services are bought or sold and at what prices, and plan other operations or activities. They also prepare financial reports and summaries, and audit payment procedures, among other responsibilities.

What is a CMO?
In this section we tell you everything you need to know about one of the most important figures in senior management, the CMO. Let’s explore the definition and what role this figure plays in an organization.
Meaning
The Chief Marketing Officer (CMO) is the executive responsible for defining and overseeing the execution of the marketing and advertising strategy. In Spain they are known as the director de marketing, and this is one of the most sought-after positions in the sector. They report directly to the executive director, i.e., the company CEO.
Functions
Their work has a very clear objective: to ensure that the product or service developed by the organization reaches the defined target. And—through an exhaustive analysis of the company results and the market—to optimize the sales profit (thus maximizing the Return on Investment (ROI)), to identify new business opportunities, and to attract new customers.
In addition to defining and overseeing the implementation of the marketing and advertising strategy, the CMO is responsible for determining the functions of the marketing and advertising department, and for setting its budget.
In short, CMOs are involved in all aspects related to the customer. And they face constant challenges from consumers and the industry as a whole, which is constantly evolving. Consequently, the roles of the CMO of any company are susceptible to constant change, so they need to be innovative and highly adaptable.
What is a CIO?
At Esade we reveal the meaning of the acronym CIO and their most important duties and impact in the company.
Meaning
The CIO (Chief Information Officer) is also known as the IT manager. This professional profile is responsible for the company’s IT systems, both at process level and in terms of planning. The CIO is constantly on the lookout for technological advances in the industry that can benefit the organization and increase the effectiveness or productivity.
Functions
The CIO focuses on ensuring that the company is up to date when it comes to information technology, with the aim of improving the performance and productivity of the different teams and maintaining effective communication between them.
They are also responsible for designing an appropriate ICT (Information and Communication Technology) strategy and defining the ICT policy that best suits the development of the business, and for hiring the specific talent needed to implement it.
Finally, one of the CIO’s functions is to co-create the investments to be made in new technologies with the finance department. This is no easy task considering the constant developments in this sector.
What is a CTO?
CTO stands for Chief Technology Officer. They are the technical manager responsible for the development of information systems. At Esade, we take an in-depth look at their importance and their functions, many of which are shared with the organization’s CIO.
Meaning
The CTO, Chief Technology Officer, is the leader of a company’s technical and technological department. So how are they different from the CIO? Quite simply, while the CIO concentrates on the information systems to increase their efficiency, the CTO works on the technology strategy to optimize the product or service.
