 ## What it is
 
-Role-Based Access Control (RBAC) is a method used to regulate access to systems and resources based on user roles within an organization. 
-Each job function is associated with specific roles and permissions. 
-For example, a member of the marketing team may be granted permission to view sales deals in the pipeline (*read* permission) but is restricted from making edits (*write* permission). 
-Different permissions are assigned to roles in sales, marketing, and similar distinctions apply within engineering teams.
+Role-based access control (RBAC) is a security method of managing user access to systems, networks, or resources based on their role within a team or a larger organization. 
+RBAC empowers IT administrators to identify the necessary level of access for all users with a particular job function and assign those users a role with a predefined set of permissions. 
+Organizations utilize RBAC to provide their employees with varying levels of access tailored to their roles and responsibilities.
 
 ## Problem it addresses
 
-Individually managing access permissions for multiple users across a variety of system resources and data can be a complex task. 
-Each user typically requires access to a different set of specific resources. 
-Let's consider an organization with 500 developers (users) and 300 resources with varying permission levels (read, write, and no access). 
-The administrator must ensure that each user is granted the correct permissions for all 300 resources. 
-RBAC simplifies this process by providing predefined access control based on role groups.
+RBAC addresses the challenge of controlling the resources team members and applications can access, 
+as well as the actions they can perform, especially as the number of applications and team members increases. 
+Administrators must ensure that each user has the correct permissions for the resources they need to access, 
+a task that can become cumbersome and error-prone without a structured access control mechanism.
 
 
 ## How it helps
 
-RBAC offers precise control over user permissions within software systems. 
-Depending on their roles, team members can modify a section, view it exclusively, or be completely restricted from accessing it. 
-This granular permission allocation enables team members with distinct roles to collaborate on the same system while minimizing security risks.
+RBAC provides IT teams with the capability to easily manage permissions for all users in a group simultaneously or make swift adjustments to an individual user's access level by assigning or removing a role. 
+This safeguards sensitive data and ensures that employees can only access information and perform actions necessary for their job responsibilities. 
+Overall, RBAC enhances access management, bolsters security, and boosts operational efficiency within organizations.
