The success of a Siebel CRM project, or any standard software implementation project in general, is linked to the education of the professionals who undertake it. Complex systems like Siebel CRM will not reveal their intricate patterns to naive consultants (or their managers) who believe in self-study or fast-track trainings.
The money saved on training (or no training) will be spent equally fast on project delay. It is paramount for the Siebel professional to expose him or herself to high quality instructor-led training, which is provided for example by Oracle University and its training partners throughout the world.
