I have one actor (admin), he can perform some actions over other user accounts such as creating the account, editing the account and deleting the account account. Should I do so
You can have the abstraction to Manage Accounts by having it generalize the three use cases.
Like so:
You can refer to the abstract use case where you need things to be in compact form, and refer to the much more precise "sub" use cases where you want to show details.
