The four key business requirements for the success of a business organization are as follows:

Availability

Availability is a general term that is used to describe the amount of time over a one-year period that the system resources is available in the wake of component failures in the system.

Access

Access is the process of identifying, tracking, controlling and managing authorized or specified users' access to a system, application or any IT instance. It is a broad concept that encompasses all policies, processes, methodologies and tools to maintain access privileges within an IT environment.

Accuracy

Accuracy refers to freedom from error (correctness), or closeness to truth or fact, resulting from exercise of thorough care or due diligence. Accuracy depends on how the data is collected, and is usually judged by comparing several measurements from the same or different sources.

Agility

Agility is the ability of an organization to renew itself, adapt, change quickly, and succeed in a rapidly changing, ambiguous, turbulent environment.
