Aspects generate costs for a business plan from normalized cost metric values by mapping (via a processor implementing an automated process) text artifacts of a business plan to different tags that each include a cost as a function of a time period for delivery of a service that is associated with a computer service element. Aspects also generate a summary view cost estimation as a function of the time period, costs of the mapped tags and a geographic region productive factor that is assigned to a region identified as providing delivery of the service that is associated with the computer service element. The summary view cost estimation estimates a total cost of delivering the computing services of the computer service element over time as a function of the normalized, mapped tag cost metrics.
