Overview

Predictability. Eliminates the ‘Excel Spreadsheet’

phenomenon.Oracle Workflow allows your

customers to modify your product without writing code.


Practical Considerations

Workflow is tougher (than data modeling).

Process modeling must be done up front.

Long testing periods.


Project Timeline

Medium Project (with 4-5 processes)Design Phase: 4-6 weeksImplementation: 4 weeksTesting: 4 weeksUser Acceptance: 2 weeks(Expect 4 months just for workflow)

Extending Oracle Workflow

Application ServersManagement ReportingPortal Comments


Adding Cold Fusion

Integrated Cold Fusion Rapid Application Development Data Entry Screens

Single Login (OAS manages logins)


Reporting Problems

Need to provide lots of information Workflow and Application Specific

No Out of Box Management ReportsTry to use existing reports instead of

creating new.Especially with workflow: People

want to see the same data multiple ways.


Management Reporting

No Out of Box Management Reports

Created custom approach vs. Discoverer


Portal Home Page

Title Detail Page


Comments

People want to communicate problems to others. End to End Systems

Future versions of workflow may have this functionality.

Workflow Versioning

Real World Constraints of WorkflowProcess changes

Items finish with the version they start with.

Cannot make changes to process structure on the ‘fly’.

Can change notifications (messages) users see.


Workflow Thoughts

Do up front process design work. Problem to change process later

Design reporting piece as part of original project.

Make Notifications (Messages) single point of contact.

The first project is intense.
