The Inventory of Statistical Operations (ISO) is a description of the statistical operations of the National Statistics Institute, the Ministries, the Bank of Spain and the General Council of the Judiciary Branch. The inventory is a fundamental instrument for statistical coordination and planning and is the starting point for the formulation of the National Statistical Plan.

The unit adopted as an inventory base is the statistical operation defined as the set of activities that lead to obtaining statistical results in a determined sector or subject based on the individually collected data.Also included in the scope of this definition are the infrastructure and statistical standardisation work that make possible the coordination, homogenisation and integration of statistics as well as the collection of results and synthesis preparation.

The classification by "responsible body" has not yet been fully adapted to what was determined in "Royal Decree 2/2020, of January 12, which establishes the basic organisational structure of the ministerial departments". To date, the Ministry of Defense, in accordance with the aforementioned royal decree, needs to adapt to its basic organic structure. The IOE reaches the general subdirectorate level, hence the importance of its adaptation to the new ministerial restructuring.
