Dimensions of the EI Problem from a CIMOSA Perspective Ted Goranson EI is not a pipe dream. Enterprises integrate their operations every day. The EI initiative seeks BETTER EI. The requirements for better EI include more open, vendor independent solutions. CIMOSA is an open solution which covers much of the EI space. Therefore, the approach which the program has taken can be illustrative of the solution decisions to be made generally, and arguments can be raised about the appropriateness of CIMOSA's specific choices. The paper discusses CIMOSA in the context of the extended reference taxonomy. The utility of the paper is twofold. First, it makes the taxonomy real by describing an example in more detail than in the previous papers. Second, it shows some surprising strengths of the underlying approach of CIMOSA in the EI context and discusses their relative merits. (The contents of the paper are extended from discussions on this topic held at a preworkshop workshop in Brussels.)
