Aviva was undergoing major changes in its infrastructure provision, and had chosen to impose stringent restrictions on other IT change for the duration. However a number of commercially essential or regulatory required changes had to be delivered within those constraints, including:

  • Replacement of the EDI Gateway used for batch interactions with external partners
  • Changes to ensure price transparency at insurance renewal
  • Changes to ensure appropriate affordability checks for credit payments
  • Enhancement of rating processes to incorporate detailed data on specific risks for specific vehicle models

I provided Solution Architecture support for all these projects. In most cases the design challenges were relatively minor, but each has required substantial support to structure the work so that delivery can continue within the very tight change constraints.

In addition I developed a general reference model for the insurance pricing processes, which allows an easy visual assessment of alignment of various channels to the target model.
