As an autonomous group,
I want to delegate access that the group has received to group members based on internal group policies,
So that the group can self-organize how it exercises the granted access.

Preconditions:

What conditions must be in place or assumed before this use case can begin?

There are autonomous actors, which can be People/Individuals or Groups/Organizations/Collectives

Trigger:

What (user or system) event or action initiates this use case?

Some Resource Owner grants specific access to some group actors.

Actors:

Describe the primary actor, and any other relevant actors involved in this use case

• YoYo - the Resource Owner, a group but could also be an individual
• ACME - access grantee - an autonomous group
• Alice - has an officer role in ACME
• Bob - has an analyst role in ACME
• Dyno - another autonomous group

Distinction:

What unique challenges or distinguishing factors (like technical issues, user experience needs, workflow integration, etc.) are associated with this use case?

Each group self-organizes independently of any other group

Scenario:

Describe an ideal or happy-case scenario where this use case would play out as intended.

• YoYo grants access to ACME, specifically read-write access to specific projects X, Y, Z, and all the related tasks
• ACME delegates read-write access to X and Y to Alice
• ACME delegates read-only access to X and Z to Bob
• ACME can do that delegation independently from YoYo
• When YoYo revokes ACME's access, Alice and Bob automatically lose the access delegated to them

Alternative case(s):

What alternative flows or variations should the system handle for this use case?

Delegation can be chained further

• ACME delegates access to another group like Dyno
• Dyno delegates it to its members Eve and Charlie

Error scenario:

What unexpected issues or errors might arise, and how should the system handle them?

Acceptance Criteria:

What conditions or criteria must be met for this use case to be considered successfully handled? What limitations are acceptable?

• ACME must be able to delegate access independently from YoYo
• ACME can't change any other access granted to someone else by YoYo
