Speaker: Ishan Mahajan, Program Manager, Srijan Technologies Enterprises today have multiple teams and several applications working in tandem. In such situations, combining a BPMN workflow engine with your content management system gives you a lot of flexibility in managing tasks, and keeping your teams in sync. Camunda, an open source, Java-based workflow engine can provide intelligent workflows for large enterprises. And if you are using Drupal as your enterprise CMS, it becomes very easy to design and implement a BPMN web portal that combines these two technologies. Join the webinar for a Drupal-Camunda tutorial that explains how to deploy a Camunda-Drupal connector module, and what are the business benefits for an enterprise. Who's This For? - Developers and architects who regularly integrate Drupal with other softwares, within large enterprises. - Developers and architects who are interested in learning more about Drupal's REST API capabilities and how Drupal is a great fit for creating web portals for backend enterprise software. - Developers and architects interested in learning about Camunda What's In It For You? - Learn why you need a Camunda-Drupal integration - Understand when to use a Camunda-Drupal integration - Understand how does a Camunda-Drupal integration actually work, and how to implement it

Camunda
● Open source platform for workflow and business process
management.
● Model and execute BPMN 2.0, CMMN 1.1 and DMN 1.1.
○ BPMN for structured workflows
● Ships with a set of applications to help model, execute
and administer process applications running on the
Camunda core engine.

Use Case: Drupal as BPM Portal
REST API
REST / Java API
Engine
(BPMN, CMMN, DMN)
End User

5. #SrijanWW | @srijanWhat does a BPM Portal typically
do?
● Involve End Users.
○ Easily provide BPM access to customers, vendors, partners and
other users outside of the organisation.
● Initiate workflow processes.
○ Complete tasks.
● User dashboard and Activity/Task list.
○ Task assignment.
○ Real time information and status of ongoing processes.

6. #SrijanWW | @srijanUse Drupal to enhance the BPM
portal
● Beyond task forms
○ Define rules to complete tasks.
● Send and manage notifications.
● User registration and onboarding
● User roles and groups.
● Provide instructions and support content to complete tasks.
● Content Management.
○ Setup task forms, task instruction pages and other content.
○ Other CMS features.

Drupal - Camunda Interaction
● Task screens:
○ Webforms, content pages (text,
videos etc)
● Assign a task
● Complete a task
○ On form submission (manual
approval)
○ Define rules using the Rules module
● Execute task
● Determine process path
task status and owner
● Task screens:
○ ...
Camunda ids, task type
● ...

11. #SrijanWW | @srijan
Let’s take a simple Example

12. #SrijanWW | @srijan
Camunda Tasklist

13. #SrijanWW | @srijanInitiate workflow process from
BPM Portal
● On submission of this form, a new
process instance (workflow) will
be initiated in Camunda.
● The first task (“Approve Request”)
will be available on the BPM
portal dashboard.

● Team members can view
and claim eligible tasks.

● Again, the newly created

then acted upon.

21. #SrijanWW | @srijanSetup: maximum flexibility & minimum
duplication
● Ensure all process definition is stored in Camunda.
● Let the BPM engine dictate the direction of the workflows.
● Drupal is used to manage content related workflows tasks and to mark tasks as
complete.
Drupal Camunda
● All the data captured through task forms
and task content.
● Task owner.
● Task status.
● Camunda IDs
● Only data that determines the path of the
workflow.
○ Task owner.
○ Task status.

22. #SrijanWW | @srijan
Camunda connector Drupal module
● Allows Drupal to connect with Camunda using REST.
● User dashboard to claim/assign and complete tasks.
● Configure forms and other screens for a task.
● Configure rules (using the Rules module) for a task.
● Sandbox URL: https://www.drupal.org/sandbox/ishanmahajan/2821362

23. #SrijanWW | @srijanWhy use Camunda when Drupal can
handle workflows?
● Ability to model BPMN diagrams and easily manage workflow steps.
● Process definition history & versioning
● Process definition heatmap
● Process instance history: user actions, audit logs with timestamps
● Process duration report
● REST APIs
● BPM engine shared by multiple applications within an organisation
