work flow is not triggering

Hi Gurus

I am configuring EHS Incident Management component Extension 3.0 , i was creating Standard users and assign the roles to users. choose the Standard work flow  "Incident Life Cycle :WS00500001". but i am getting below errors .

1) If iam creating incident , getting message Incident recorded successfully & concern incident manager has being notified.

2) If i was checked in Incident manager credentials(Standard Roles are assigned to Incident Manager) , in Work overview there is no incidents are appearing and as well as in search also there is no indents are appearing.

can you please guide where iam doing mistake.
