  • Improving Delivery of City Services. The City is committed to accessing Cambridge’s diverse body of expertise to develop new analyses, insights, and findings which potentially could assist the City’s efforts in providing efficient and effective government services.
  • Realizing Social and Commercial Value. Because data is a key resource for social and commercial activities, the large amount of data generated by the City can be a resource in creating innovative business and services solutions that deliver social and commercial value.
