Regulatory drivers

• Chapter 1, Part III.E Planning
• A head of department shall establish-
• an information plan that supports the processes
  and objectives of the department.
• an information technology plan that supports the
  information plan and
• an operational plan that enables the
  implementation of the information technology plan
  and information management.
• Chapter 5, Part II e-Government
  Interoperability
• Comply with Minimum Interoperability Standards
  (MIOS) for
• every part of any new information system
  developed or acquired for the public service or
  any upgrade of any existing information system in
  the public service and
• every legacy system that is part of electronic
  service delivery in the public service.

EA Process (TOGAF)
EA Framework Principles
Validate Requirement at every phase
Define EA Scope, Vision, Drivers and Baseline
Keep Architecture up to date
Ensure PROJECT Compliance to Architecture
Develop IMPLEMENTATION Roadmap
Identify PROJECT INITIATIVES

Interoperability and MIOS

temporarily believe if one thinks too long
alone." - John Maynard Keynes

MIOS v4.1 Status

• XML as a Standard
• XML (Extensible Mark-up Language) is the
  cornerstone of the Government data presentation
  and integration strategy but XML alone is not
  sufficient.
• Need to add XML data schemas for use throughout
  the public sector.
• Future version of MIOS (v5.0) will include
• Technical Reference Model (TRM) as reference and
  classification schema for all interoperability
  standards.
• Government sector/cluster specific data
  interoperability standards
• Add a rationale to comply (applicability
  clauses).
• Implementation guidelines
• Improve the MIOS development process and
  responsibilities.
• Review Process and Frequency
• Annual basis through the GITOC Standing Committee
  on Architecture with due process of consultation.

21
Conclusion

• National XML Standards prospective benefits
• Improve the interoperability maturity level among
  government Information Systems
• Enable e-Government programmes to proceed more
  effectively and efficiently
• Set a standard by which to certify the
  acquisition of Government Information Systems
• Whilst observing the following principles
• Collaborative process among Departmental
  stakeholders (architects, software engineers and
  managers) to strengthen collective ownership at
  GITOC level
• Maintain a balance between rigor and innovation
  (Goldie Locks Tale)
• Must be certifiable
• Must be manageable in its through-life of
  existence and
• Open freely available to public and private
  entities to ensure transparency and competitive
  bidding.
