Business Architecture (BA) is called to play a central role in a programme as complex as that of modernisation and standardisation of the official statistical information production. This study aims at illustrating a BA model for achieving a unity of views, so as to ensure the strategic alignment in each part of an Organisation and to carry out an innovation consistent with the standardisation objective that should be reached. This BAmodel individuates four different business lines (Strategy; Corporate support; Production; Capability) and is led by common infrastructures and principles that become instruments and guidelines for the implementation of each business line group of actions. Both principles and infrastructures facilitate and enhance the standardisation process.
