Description

The purpose of creation is an implementation of the capability for users to participate in the APG process to make decisions without logging in ARIS by providing decision buttons in the e-mail body (“e-mail task”).

The solution consists of the following components:

  1. REST-API Web service – ensures receiving decisions from users, storing decisions, and providing them on request.
  2. APG-service for sending user operations “e-mail task” - provides sending e-mails in Html format with GUI elements for decision making.
  3. APG-service for receiving and processing user answers of “e-mail task” operations.
  4. ARIS-script for creating a graphic image of the model.

During setup a standard APG-service (contained in ARIS by default) is embedded in the ARIS Process Governance process to run the script (component 4). The script generates a graphic image of the context model, stores it in RAM as bytes to transmit back to the APG process.

Next an APG-service (component 2) is embedded in the process. It is necessary to transfer ARIS-users as well as a previously prepared graphic image to the input of the service. A separate e-mail with text, a graphic image of the model, and buttons for decision making are sent to each user.

After receiving an e-mail, the user transfers the decision to the Web service (component 1). For this, the user clicks one of the buttons in the e-mail. By clicking the button, the browser opens a link containing an e-mail task identifier and a decision. The Web service receives and stores this information, and the user sees a message in the browser that the decision has been considered. This user action can be performed either on a personal computer or a smartphone/tablet running on any operating system.

Then the next APG-service (component 3) is embedded in the process. This service is purposely separated from component 2, so receiving user decisions can be integrated into the process more differently, for example, in parallel with other operations. The component requests information regularly about the decisions taken from the Web service. When specified conditions are met (e.g., all users have made decisions), the component completes its execution. The output provides lists of users grouped by decision.

Example of the “e-mail task”:

Example of the link that provides sending user decision to the Web service:

http://<servername>:<port>/e-mailtask/p/89d19eb6-2097-4610-84a6-bf690a166e2e/positive

Example of the Web service answer about receiving information (can be customized):

Essential working conditions of REST-API Web service

Since Web service is developed in Java, the installation of JRE (Java Runtime Environment) is required to run the service on OS Windows. It is also possible to use a portable version of JRE.

To pass requests to the Web service from the users and the APG-service, the network must be configured accordingly. To do this, define a free standard Http port (e.g., 80) in the Web service configuration file and/or open it in the firewall:

Server with Web server - rule for inbound connections;

Servers (nodes) with APG - rule for outbound connections;

User PCs – rule for outbound connections.

If you have interest or questions how integrate this solution to your APG processes infrastructure, please, contact us  to  discuss  details  and further cooperation.
