OMB updating architecture reference models for '06 budget process

Agencies should expect to have updated versions of four of the five Federal Enterprise Architecture reference models before the fiscal 2006 budget process begins in February, an administration official said.

Bob Haycock, the Office of Management and Budget's chief architect, today said his office is working with agencies to improve the four reference models'Business, Service, Technical and Performance'that his office has released. OMB also will send out a draft copy of the Data Reference Model in the next few months for agency comment.

'It was a good start, but we knew we would have a lot of work to do on the Service and Technical reference models because of how technology and service components are always changing,' Haycock said today at a Solutions Architecture Boot Camp sponsored by the Interoperability Clearinghouse of Alexandria, Va.

The data model will describe how agencies use information to support their lines of business. Haycock said the architecture team working on the model is following the ISO 11179 standard for classifying data elements and developing rules for data definitions.

'This is incredibly hard to do, and there are many ways to skin a cat, and all are correct,' Haycock said. 'We hope to add a line of business context to the data, but we are not sure how to do that yet.'

OMB also is starting to develop a description of common business processes that are more specific than the 153 subfunctions listed in the Business Reference Model, Haycock said.

'We want to describe the attributes of the business lines in a consistent way for all agencies,' Haycock said.
