Book excerpt: This review analyses public procurement policies and practices of ISSSTESON, the institution providing health and pension services to the workers of the State Government of Sonora, Mexico. It benchmarks ISSSTESON practices against the 2015 Recommendation of the Council on Public Procurement to help the institute upgrade its procurement operations and increase efficiency, in a difficult financial environment. It also examines the revenue structure of the Institute and suggests reforms for the pension scheme, which is too generous compared to national and international experience.
