Approach - Solutioning
Domain decomposition represents a top-down approach
where business domains are decomposed into functional areas
across the value net. Through this technique we can establish
the scope of the effort. After domains have been decomposed
into functional areas, each area can then be further
decomposed into processes and sub-processes and high-level
