Continuous work with the model ensures that both equations and data are developed and improved. A new model version will typically collect the results of research efforts in several areas. A new model version is thus associated with testing, error detection and documentation. Before releasing a new model version, users are invited to test a beta version throughout a period of approximately 3 months. After the beta period the new model is finalised and serves as the official model version.
A model version is a package with a new model, new data bank and revised forward projections and base line. In addition it is often necessary to revise many of the tools and smaller models that are offered together with ADAM. Documentation of equations, data and model characteristics are renewed in connection with the production of a new model version. The model versions are typically released every 1-2 years. The frequency varies depending on the number of changes in equations and data. It can be more frequently, for example in connection with main revisions in the National Accounts.
