Strategic Dependency Model and Context Diagram
In the following figure the strategic dependency diagram for the e-Government case study is reported. The diagram reports the dependency between User (a Citizen, a Government Agency or a Company) and Public Body to the satisfaction of the goal Require service; moreover User depends on the Certifier service to gain trust on the obtained output, while the Certifier service is needed by the Public Body to authenticate the service output. Moreover User needs the E-payment service to satisfy the softgoal Charge Fee.
The following figure represent the context diagram of the e-government case study.
In the next figure the domain model of the e-Government is reported.

In the following figure the general use case diagram for the e-Government case study is reported.
| Field | Description |
|---|---|
| UniqueID | TIS-ENG-1 |
| Short Name | Request for e-Government service |
| Related To | TIS-BG-1, TIS-BG-3, TIS-BG-4, TIS-BG-5, TIS-BG-6 |
| Involved Actors | User |
| Detailed Operational Description | This scenario describes the submission of applications to obtain subsidies from the province of Bolzano, Italy. In the e-government application the process is started by the user that, after the login, chooses the service he needs. So the user inserts the needed data to compile the form for the request (he could decide to compile the form from the scratch or updating preexistent data). Actors involved in the scenario are the users of the application (citizen, companies or government agencies). |
| Problems and Challenges | When a user requires a document or a service he submits a lot of personal data. The confidentiality of the data must be guaranteed by the application, moreover the user must be assured that provided data are not used outside that transaction. |

| Short Name | Output Authentication |
| Related To | TIS-BG-5, TIS-BG-6 |
| Involved Actors | User, E-Certifier service |
| Detailed Operational Description | The user could require an authenticated output, so the application has to provide a mechanism to certify the output.
|
| Problems and Challenges | A mechanism of digital signature must be provided to guarantee the authentication of the output. |
