Step-by-step explanation:
The method used to regulate the modification of systems within an organization by requiring formal review and approval for each change is called change control.
Change control is a process that ensures any modifications made to the organization's systems are thoroughly reviewed, analyzed, and approved before implementation. It helps maintain the integrity of the systems and prevents unauthorized or detrimental changes.
One example of change control is the use of a change advisory board (CAB). The CAB consists of representatives from different departments within the organization who evaluate proposed changes and determine their impact on the systems and overall operations.
