V. THE BENCHMARKING METHOD IN ENTERPRISE
ARCHITECTURAL PLANNING PROCESS
What this paper has been focusing on is the utilization of
benchmarking using the best practices in the enterprise
architecture planning process. As has been described in
sections 2-2 and 3-2, the benchmarking may be used in two
sections of target architecture and transition plan from
enterprise architecture planning process. In this section the way
they were presented in two above sections are being studied.

benchmarking process is divided into three types; Functional

Organizational State
The domains which have been selected in the first part are
being examined in organizations that are chosen as a best
practice. Also the informal organizational state must be
examined in the same domains.
4) Gap Analysis
After having studied the best practices and the informal
organizational state, the distance between them must be
analyzed. Various approaches of gap analysis mentioned in [4]
can be used to carry out the task.
5) Feasibility Study
After having studied the gap analysis, it is the time to
