The main roles include:
A corporate developer is then responsible for mapping the specification into design and implementation and tying the logical flow with the actual applications, portals and services. A new level of detail and variability is introduced here: data transformation, exception management, timeouts, business transactions, etc...
Finally business users need activity monitoring and business reporting.
The main tasks involved include:
Specification (owned by business analyst)
Implementation (owned by corporate developer)
Delivery and administration (owned by ops)
Activity monitoring (for business users)
Customization and adaptbility (rapid cycle business user, business analyst, corporate developer)
I would appreciate feedback to this picture.
This model is fundamentally correct. I would add that each phase you discuss can be drilled into more detail. The larger the project, the more carefully the phases and tasks are segmented. The smaller the project, the more blurred the phases and roles.
