# OPS02-BP05 Mechanisms exist to request additions, changes, and exceptions
OPS02-BP05 Mechanisms exist to request additions, changes, and exceptions

You can make requests to owners of processes, procedures, and resources. Requests include additions, changes, and exceptions. These requests go through a change management process. Make informed decisions to approve requests where viable and determined to be appropriate after an evaluation of benefits and risks. 

 **Desired outcome:** 
+  You can make requests to change processes, procedures, and resources based on assigned ownership. 
+  Changes are made in a deliberate manner, weighing benefits and risks. 

 **Common anti-patterns:** 
+  You must update the way you deploy your application, but there is no way to request a change to the deployment process from the operations team. 
+  The disaster recovery plan must be updated, but there is no identified owner to request changes to. 

 **Benefits of establishing this best practice:** 
+  Processes, procedures, and resources can evolve as requirements change. 
+  Owners can make informed decisions when to make changes. 
+  Changes are made in a deliberate manner. 

 **Level of risk exposed if this best practice is not established:** Medium 

## Implementation guidance
Implementation guidance

 To implement this best practice, you need to be able to request changes to processes, procedures, and resources. The change management process can be lightweight. Document the change management process. 

 **Customer example** 

 AnyCompany Retail uses a responsibility assignment (RACI) matrix to identify who owns changes for processes, procedures, and resources. They have a documented change management process that’s lightweight and easy to follow. Using the RACI matrix and the process, anyone can submit change requests. 

 **Implementation steps** 

1.  Identify the processes, procedures, and resources for your workload and the owners for each. Document them in your knowledge management system. 

   1.  If you have not implemented [OPS02-BP01 Resources have identified owners](ops_ops_model_def_resource_owners.md), [OPS02-BP02 Processes and procedures have identified owners](ops_ops_model_def_proc_owners.md), or [OPS02-BP03 Operations activities have identified owners responsible for their performance](ops_ops_model_def_activity_owners.md), start with those first. 

1.  Work with stakeholders in your organization to develop a change management process. The process should cover additions, changes, and exceptions for resources, processes, and procedures. 

   1.  You can use [AWS Systems Manager Change Manager](https://docs.aws.amazon.com/systems-manager/latest/userguide/change-manager.html) as a change management platform for workload resources. 

1.  Document the change management process in your knowledge management system. 

 **Level of effort for the implementation plan:** Medium. Developing a change management process requires alignment with multiple stakeholders across your organization.
