             to support that initiative. Then IT develops the associated applications, data and technology  Notes
             infrastructure, and the process repeats itself each time another strategic initiative is defined.
             Over time, the company ends up implementing separate and  disconnected IT systems
             without an overarching plan. Far from helping to shape the future of the company, IT
             becomes the bottleneck, continually reacting to the latest strategic initiative.
             Dell has overcome this tendency with its architecture-driven approach. For example, one
             area where Dell identified silo-ed but well-intentioned plans was in the development and
             delivery  of support  tools. Various product teams (e.g. notebook team, desktop  team,
             server team, etc.) were capturing diagnostic information for evaluation. From a customer
             viewpoint, consistency in how these capabilities are delivered is very important, leading
             Dell to think about its support to tools across all product lines and to use common develop/
             design and support processes.
             Gass believes that IT must lead the business in any type of large, transformative project. IT
             is the facilitator and  IT can drive accountability  in the  business owners and help the
             various domains interlock.
             A Foundation for Execution

             Establishing business architecture involves capturing various “views” of the enterprise
             such as the business strategy, business capabilities, business processes, knowledge, and
             organization. In most EA projects, this information is used throughout the architecture
             development process to:

                Identify business and IT “owners” to sponsor  and participate in the  architecture
                 review and transformation process
                Prioritize the areas in which to focus rationalization efforts

                Capture business capabilities and business process insight
                Eliminate redundancies and gaps in the applications portfolio
                Align IT initiatives with business strategies and goals
             Dell has a systematic  method for achieving these  objectives. Every  year its  business
             architecture team sits down with the strategy planning office to review essential capabilities
             and complete a strategic plan. This plan typically focuses three to five years in the future.
             Gass and her team maintain a corporate-wide map of these capabilities that depicts specific
             business domains – what they call “process chevrons.” This map provides a logical model
             of how Dell runs. The business architecture team looks for “capability gaps” and then
             interacts with the solution architecture team, the information architecture team, and the
             infrastructure team to fill those gaps. Dell’s Enterprise Architecture team maintains three-
             year reference architecture for each of these domains, which they update each quarter.
             Creating Business/IT Alignment

             Dell prioritizes its IT investments by aligning them with the reference architecture and
             identifying the capabilities with the highest return on investment. Gass and her team
             enforce the technology  reference models and provide  an architecture review board to
             govern the transformation effort. The EA team periodically assesses the degree to which
             each project has  realized  the  transition state  on  the  way to  the three-year  reference
             architecture.
             Dell has made it clear to its managers and business process owners that they don’t “own”
             an organization or that organization’s requirements. Rather, they own a capability area.
             Certain assets are associated with that area, including the business architecture, business
