A CIO is an incredibly important position in a company, and they have a lot of duties you should know about, especially if you work with one closely or if you’re trying to become one. So, we’re here to help you learn more about a CIO and what they do.

Today’s word of the day is CIO. By the end of this short guide, you’ll have a solid understanding of the word CIO, its definitions, its etymology, and how to use it. 

What Is the Meaning of the Word CIO?

The acronym CIO stands for Chief Information Officer and sometimes for Chief Investment Officer. They are both important chief roles in any company. Here are the definitions of CIO. 

Chief Information Officer

Essentially, the Chief Information Officer is a company’s IT department head. Their specific day-to-day roles will vary depending on the company. Still, in general, they focus on information technology, maintaining those systems, and keeping the company’s technology up to date with various new initiatives and a great deal of business strategy. 

Sometimes, this person is called the CTO or Chief Technology Officer. The role of the CIO position is incredibly important. Their work keeps a company’s data safe, helps a company with important software they use, and maintains the computer systems of a company. 

Chief Investment Officer

A Chief Investment Officer is a very different role. They focus primarily on a company’s big-picture investment strategy and ensuring a company’s big investments have adequate yield. 

The CIO directs investment strategy and crafts a company’s investment vision and strategy in the long term. To be a CIO, you need to be great at finances, familiar with the investing process, and skilled in risk assessment. 

Other Lesser Used Definitions

CIO can also stand for “Congress of Industrial Organizations.” It was a group that brought many black workers into labor unions. It was founded in the 1930s. In 1955, it merged with another union group to make the AFL-CIO (American Federation of Labor and Congress of Industrial Organizations,” which is the largest federation of unions in the US.

Where Did the Word CIO Come From?

To help clarify the definition of CIO, let’s look at the history of how it came to be. 

Chief Information Officer

The first CIO position that came about was the Chief Information Officer. In the 1980s, with the rise of the internet and technology becoming a more integral part of business, it was important for companies to undergo a digital transformation process, procure digital information systems, and implement more digital technologies. 

As this need arose, people created the CIO role. In the beginning, CIOs were tasked with creating these systems. These important business leaders are now the head of IT operations. They are in charge of all of the IT professionals within a company and work to create a great digital environment within the company. 

Chief Investment Officer

The career path of the Chief Investment Officer is quite different and much newer. The role seems fairly similar to the CFO (Chief Financial Officer). Although the two work closely together, the CIO focuses specifically on financial investments, while the CFO focuses on a company’s general finances and budget. 

This c-suite job title is a big deal, especially for companies with huge assets and a large investment portfolio. As companies have become much larger in scale and stock management has become a much more important part of large-scale business, a need for a Chief Investment Officer has arisen. But this is a fairly new role that has only existed in recent decades.
