MY JOURNEY TO BUSINESS PROCESS MODELS & SOA 

2009: Oversight consultants introduced process models While being audited by an oversight company I was exposed to their methods to elicit and capture business processes. http://www.pixnio.com/people/technical-staff-review-audit-findings 

2010: Developers and early adopters embrace Models Process Models Embraced by: •  Development Team •  Data Managers •  Documentation Team Photo of my team on large on-site development project 

2016: Embedded Models in End User Applications Accelerated user adoption by presenting process models to end users, complete with video tutorials for any given task.

Human Tasks, Timers, and Scripted Tasks “Clock In” and “Clock Out” are human tasks. Timer events can trigger additional flows. In this case, triggering an automated scripted task to notify the manager should the employee be tardy. 

Interrupting vs Non Interrupting Events The Clock In Timer Event is non- interrupting. The Clock In task is still expected even though the manager has been notified. The Employee Excused message received event is interrupting. The Clock In task is no longer expected. 

Sub Process Activities Update Payroll Records is presented as a Collapsed Sub process. Collapsed sub processes encapsulate additional activities.

Task List Webapp Task List – Web interface where process participants can locate & complete their tasks. •  Filters •  Claim / Release •  Set Follow-ups •  Deadlines •  Task View https://docs.camunda.org/manual/7.5/webapps/tasklist/dashboard/ 

Cockpit Webapp Cockpit– Web interface where process operators can manage processes and monitor performance. •  Duration Reports •  Process Instance Views •  Process Definition Views •  Migrations https://docs.camunda.org/manual/7.5/webapps/cockpit/ 

Admin Webapp Admin– Configure access. •  Users •  Groups •  Permissions https://docs.camunda.org/manual/7.5/webapps/admin 

REST API Rest Api – Comprehensive and documented access to all the relevant interfaces of the engine. Enables Custom End User Applications https://docs.camunda.org/manual/7.5/reference/rest/ 

Custom Applications Existing Applications Bring end user tasks and operational management features directly into existing custom applications. Enhanced User Experiences Innovate on user tasks. For example, display geo-coded tasks on a map. 

Services Services Web end points where automated scripts can perform tasks on a users behalf. Internal Services A service developed by your company to enable automation. External Services Hosted, vendor, partner or client endpoints.
