[Adapting the service portfolio of a public health organisation to shrinking resources]

This paper describes the review process of the Agency of Public Health of Barcelona's service portfolio in response to the budget cuts introduced since 2010 in the public administrations in Spain. A working group reviewed the different business activities, taking into account their costs and generated revenue and their justification, assessing factors such as the existence of legal constraints, tied funding, explicit demands from the founding administrations and other actors that may be capable of undertaking particular activities. The changes and their consequences are described. The new service portfolio has been consolidated and is considered ratified by the Agency board, which was renewed after political changes. We conclude that this is because it was based on professional consensus and management criteria, which are key for the smooth operation of a public autonomous executive organisation.
