our approach to capacity planning
Our Approach To Capacity Planning

Our risk managed model has a bias for Capacity.

  • Our Capacity Planning approach seeks to provide sufficient resources in the right places.
  • We seek to limit/reduce costs while not increasing Wells Fargo’s risk.
  • We seek to right-size our existing capacity by reducing/removing under-utilized resources.

Capacity Planning is the discipline of managing risks and priorities.

Capacity Planning seeks to maintain an appropriate balance among differing priorities:

Cost vs. Capacity – ensure that existing processing Capacity, and Capacity to be purchased, is not only cost justifiable in terms of business need, but also makes efficient use of purchased resources.

Supply vs. Demand – ensure that the available supply of processing power matches the demands made on it by the business, both now and in the future.

The value and risk associated with each drives our approach to Capacity Planning.

We focus on delivering an optimal, cost effective, and risk balanced computing environment for our customers and team members.
