  16. 16. GEAF of NCA (12/12) Building Blocks & Working Products ? Architecture vs. Supporting Work Products - Archtecture products Essential work products are required to be produced for an enterprise. These generally present the broadest perspective of the enterprise. - Supporting products Supporting work products generally provide more depth or more specialized perspectives of the enterprise. 16 National Computerization Agency

  25. 25. Comparison with TOGAF(9/9) Working Products & Building Blocks ? TOGAF : - has detailed and specified working products according to developing processes in ADM - shows changes & updates of working products as process flows - shows various kind of Building Block such as ADML… ? GEAF : - only giving definition statement of Building Blocks and Working Products. - not clearly demonstrating naming of detailed Building Blocks and Working Products. ? Characteristics of Public Sector's IT project in Korea - BB and Working Products are not clearly defined - IT Outsourcing Industries' demend 25 National Computerization Agency
  26. 26. Future Work ? “TOGAF” as TTA Standard for private IT Sectors * TTA : Telecommunications Technology Association ? “GEAF” as TTA Standard for public IT Sectors ? Development of ADM & BBIB for GEAF q Methodology is more important q TOGAF as reference for GEAF q Utilization of TOGAF results and following-up of TOGAF 26 National Computerization Agency
