Step-by-step explanation:
The most likely title of the person who recommends enterprise-wide upgrades of computer hardware in a company with a large and effective IT workforce would be Chief Technology Officer (CTO). The CTO is responsible for overseeing the company's technology strategy and ensuring that it aligns with the company's goals and objectives.
They are typically highly knowledgeable about computer hardware and software and make recommendations for upgrades based on the company's needs and industry standards. For example, if the company is experiencing slow performance and compatibility issues with outdated hardware, the CTO may recommend upgrading to newer and more powerful computers to improve efficiency and productivity.
In contrast, the other options listed - Chief Information Officer (CIO), Chief Financial Officer (CFO), Systems Analyst, and Information Resources Manager - may have roles related to IT, but their primary responsibilities do not typically include making enterprise-wide hardware upgrade recommendations.
