Initial target date to finish: 1-1-2006 Basic version 1 Initial target date to finish: 1-1-2006 Basic version 1.0: 1-7-2005 Basic version valid for statistics: 1-7-2006 Next releases: 1.5, 1.75 (both in 2007), 2.0 (in 2008) 23rd October 2007
Contents + derivation process Points of departure Output: Eurostat legislation + needs customers Process: completely automatic preliminary statistical frame Profiling for large (preliminary) EGs Macro-analysis one frame a month 23rd October 2007

Review Personal view External view 23rd October 2007
Review: personal view: +++ (1) Projectteam: enthusiastic, problem-solving, not many register people Well documented Consistent system Selections reproducible Meta data Rational tools: CQ, CC Performance problems solved Internal address changes outside BR 23rd October 2007
Review: personal view: +++ (2) Stable and clear interactive profiling tool Preliminary stat. frame reproducible Flexibility (derivation prescriptions) Local unit now own unit Data selections, pull principle HR+UWV BBR+HR+BVR Macro analysis Objectives achieved 23rd October 2007
Review: personal view: - Not ready yet for NACE revision No research on new output for customers No history on all legal units Too few people have good knowledge Retroactive changes almost impossible For one statistic no data available on time Project split: (scoping, prioritizing)n Poor provision of documents EGs not always in one event Instability #emp Identifications lost 23rd October 2007
Review: Audit Complex system Investments higher 1.0 restricted functionality, 2.0 is needed Future proof Not cf. Application architecture SN Introduce unit + regression tests Can be skipped, if short of time. 23rd October 2007
Preview 1.75, 2.0 versions, issues NACE revision New trade register (BBR successor) New Eurostat legislation Euro Groups Register Activity coding system 23rd October 2007
