Which term describes a company's capability to use cloud services effectively?

The term that describes a company's capability to use cloud services effectively is cloud readiness. This concept encompasses an organization's preparedness to adopt cloud solutions, including their existing IT infrastructure, skills, processes, and overall strategy for integration. Cloud readiness assesses whether the organization has the necessary resources and mindset to transition to and utilize cloud services efficiently.

A company's cloud readiness includes evaluating its ability to manage change, train personnel, and adapt business processes to leverage cloud technologies effectively. This capability is essential for successfully implementing cloud solutions and achieving the desired business outcomes, as it ensures alignment between an organization's goals and the cloud's potential benefits.

While cloud agility, efficiency, and scalability are all important aspects of working with cloud solutions, they pertain to how well a company can respond to changes, optimize resource usage, and expand its services, respectively. These concepts are crucial but do not encapsulate the overall preparedness an organization needs to start using cloud services. Hence, cloud readiness is the most appropriate term for describing a company's capability to utilize cloud services effectively.
