This framework provides management with a structure to measure and control information technology in accordance with generally accepted criteria incorporated in the guideline Control OBjectives for IT (COBIT) published by the Information Systems Audit and Control Association (ISACA).

defining the information architecture
    that satisfies the business requirement
    of optimising the organisation of the information systems
     
      is enabled by
      • creation and maintenance of a business information model
      • ensuring appropriate systems are defined to optimise the use of this information

        and takes consideration

        • automated data repository and dictionary
        • data syntax rules
        • data ownership and criticality/security classification
        • an information model representing the business
        • enterprise information architectural standards

  Conclusions:
* Non-existent 
There is no awareness of the importance of the information architecture for the organisation. The knowledge, expertise and responsibilities necessary to develop this architecture do not exist in the organisation.
* Optimised 
The information architecture is consistently enforced at all levels and its value to the business is continually stressed. IT personnel have the expertise and skills necessary to develop and maintain a robust and responsive information architecture that reflects all the business requirements. The information provided by the information architecture is consistently and extensively applied. Extensive use is made of industry best practices in the development and maintenance of the information architecture including a continuous improvement process. The strategy for leveraging information through data warehousing and data mining technologies is defined. The information architecture is continuously improving and takes into consideration non-traditional information on processes, organisations and systems.
* Managed and Measurable 
The development and enforcement of the information architecture is fully supported by formal methods and techniques. The process is responsive to changes and business needs. Accountability for the performance of the architecture development process is enforced and success of the information architecture is being measured. Formal training activities are defined, documented and consistently applied. Supporting automated tools are widespread, but are not yet integrated. Internal best practices are shared and introduced to the process. Basic metrics have been identified and a measurement system is in place. The information architecture definition process is proactive and focused on addressing future business needs. The data administration organisation is actively involved in all application development efforts to ensure consistency. An automated repository is fully implemented and more complex data models are being implemented to leverage the information content of the databases. Executive information systems and decision support systems are leveraging the available information.
* Defined Process 
The importance of the information architecture is understood and accepted, and responsibility for its delivery is assigned and clearly communicated. Related procedures, tools and techniques, although not sophisticated, have been standardised and documented and are part of informal training activities. Basic information architecture policies have been developed including some strategic requirements, but compliance with policies, standards and tools is not consistently enforced. A formally defined data administration function is in place, setting organisation-wide standards and is beginning to report on the delivery and use of the information architecture. Organisation-wide automated data administration tools are emerging, but the processes and rules used are defined by database software vendor offerings.
* Repeatable but Intuitive 
There is an awareness of the importance of an information architecture for the organisation. A process emerges and similar, though informal and intuitive, procedures are followed by different individuals within the organisation. There is no formal training and people obtain their skills through hands-on experience and repeated application of techniques. Tactical requirements drive the development of information architecture components by individuals. 
* Initial / Adhoc 
Management recognises the need for an information architecture, but has not formalised either a process or a plan to develop one. Isolated and reactive development of components of an information architecture is occurring. There are isolated and partial implementations of data diagrams, documentation, and data syntax rules. The definitions address data, rather than information, and are driven by application software vendor offerings. There is inconsistent and sporadic communication of the need for an information architecture.
