1. General Context
As part of the transition from STM V4 to STM V5, the permission management system is evolving towards a workflow-based model.
This change involves significant updates to the way user permissions are managed.
2. STM V5 Operating Principle
A V4 permission becomes a V5 workflow.
A workflow includes:
Product restrictions
Quotas
Access controls also exist, but they are managed separately. They allow you to define:
Machine restrictions
Time periods
â ď¸ Key STM V5 rule:
A user can only have one workflow.
Objectives:
Avoid inconsistencies
Eliminate permission conflicts
3. Role of SAM in the Migration
The SAM system is able to:
Recreate V4 permissions as V5 workflows
Assign these workflows to users
â ď¸ Very important point
SAM recreates all permissions as workflows, whether they are used or not.
Unassigned permissions are also recreated
No selection is possible
đ Operating rule:
SAM recreates either all permissions or none.
4. Migration Cases
Case no. 1: User with a Single Permission
â Simple situation
The permission is converted into a workflow
The workflow is automatically assigned
No adjustment is required
Case no. 2: User with Multiple Permissions
â ď¸ Complex situation
Problem
In V4: multiple permissions are possible
In V5: only one workflow is allowed
Consequence
During migration:
SAM can only assign one workflow
It is not possible to automatically merge multiple permissions
Applied rule
đ The assigned workflow corresponds to:
the oldest permission
Impact
Loss of the other permissions
Non-optimized operation if no action is taken
đ Decision to Be Made After the Assessment
Following the company assessment provided by SAM, a strategic choice must be made.
Option 1 â Start from Scratch (Recommended)
Recreate clean and consistent workflows
Adapt permissions to actual usage
Optimize access management
đ The most reliable and sustainable solution
Option 2 â Keep an âISO V4 Permissionsâ Operating Model
Keep an operating model close to the existing one
Based on a single workflow derived from the oldest permission
Without any real optimization
â ď¸ This option results in:
A loss of business logic
Permissions that may be incomplete or unsuitable
A suboptimal operating model
5. Actions to Be Planned by the Client / Distributor
Request an assessment.
SAM can provide Excel files containing:
List of users with their current permissions
List of users whose permissions will not be fully migrated
6. How to Obtain This Information
đ Contact:
The SAM sales representative
or
SAM Customer Service
7. Recommendations
Identify users with multiple permissions
Analyze actual usage
Prioritize a clean reconstruction of workflows
Plan a reconfiguration phase
8. Conclusion
Automatic permission migration, all or nothing
Limitation to one workflow per user
Need for arbitration in complex cases
đ Preparation and decision-making in advance are essential to ensure a successful transition.
Example Attached Below
Explanation of the Example
The top table represents an assessment of permissions in STM V4.
Users could have multiple permissions
These permissions could sometimes conflict with each other
This was how STM V4 worked, but it was not optimal
With the transition to STM V5:
Permissions become workflows
A user can only have one workflow
đ During migration:
If a user had multiple permissions
They only keep one
This workflow corresponds to:
the oldest permission
â ď¸ Important:
This is not an addition of permissions
The user does not recover all of their initial authorizations
đ Result:
Access rights and restrictions may be different after migration compared with before.
Please Note
All permissions are recreated identically as workflows.
However, some workflows may not be assigned to users because those users will already have another one.
