Enterprise Architecture Aligning IT and Business during Integration Antonio Rios April 2008

Enterprise ArchitecturePage 2 Agenda ► Enterprise Architecture and Enterprise Planning ► Enterprise Architecture Modeling ► Business and IT Integration ► Case Study: Motorola

Enterprise ArchitecturePage 3 Enterprise Architecture and Enterprise Planning ► Enterprise Architecture (EA) is the organizing logic for business processes and IT infrastructure, reflecting the integration and standardization requirements of the firm’s operating model 1 ► EA provides line of sight into ► Business Operations that carry out the corporate mission ► Information and applications used to enable those business operations ► Technology Infrastructure that drives those applications and data resources ► Up-to-date representation of an organization’s infrastructure, processes, and relationships 1.-

Enterprise ArchitecturePage 4 Enterprise Architecture and Enterprise Planning ► EA typical application Define baseline architecture Where do we want to be? Initial state Baseline React to changes

Enterprise ArchitecturePage 5 Enterprise Architecture and Enterprise Planning ► Enterprise Planning relies on EA to provide the up-to-date view of the organization ► Without a plan, the organization is vulnerable to unfolding events, new technologies, or unanticipated factors ► When shifts in strategic direction occur, EA guides the decision-making process by providing timely and concise information ► Identifying current-state architectures and developing optimal target-state architectures is challenging because the organization is constantly in flux

Enterprise ArchitecturePage 7 Enterprise Architecture Modeling ► Modeling provides tangible artifacts (models) that allow business and IT decision makers to allocate funding and implement projects that will deliver the most value to the organization ► Models represent various aspects of the organization, including both the current and target states of the enterprise ► Through modeling, business analysts can identify resources with poor value, obsolete processes and technologies, and existing gaps in business or IT capabilities

Enterprise ArchitecturePage 8 Business and IT Integration ► Enterprise Architecture becomes a critical component during business and IT integration activities ► Having a clear representation of two organizations business, IT, and infrastructure components allows the decision makes to plan and implement a target architecture ► Poor current-state architecture and models will lead to undue stress, confusion, and increased cost during integration activities ► An organization’s ability to react quickly to external factors (such as business and/or IT integrations) is directly influenced by the maturity and accuracy of its EA models

Enterprise ArchitecturePage 9 A case study: Motorola ► Motorola acquired Symbol Technologies in 2007 ► Consumer ► Enterprise ► Government ► Service Providers (networks, applications, services, etc)

Enterprise ArchitecturePage 10 A case study: Motorola (cont.) ► Integration of Symbol Technologies into Motorola’s existing Enterprise Mobility business line ► Lack of clear picture for all of Symbol’s business applications, systems, and elements of IT infrastructure ► Widespread use of Visio and PowerPoint to document existing architecture ► Difficult to size up overall integration effort ► Telelogic System Architect selected as tool for modeling during and post-integration ► Massive effort to document current state

Enterprise ArchitecturePage 11 A case study: Motorola (cont.) ► Telelogic System Architect ► Graphic models and their underlying information created and stored in a relational database ► Users build the models working together in teams on the network ► As one user opens a model artifact to edit it, other users get a read-only version of this artifact ► Users can check out multiple artifacts so that they can work on sections of the architecture without anyone else modifying it while they work on it ► A SQL-based query reporting language enables users to build and run reports to answer questions about the information they have modeled ► what business processes are related to what organizational goals ► what applications are used to perform what business processes ► what business processes operate on what data entities ► what user has modified what information on what date ► etc

Enterprise ArchitecturePage 12 A case study: Motorola (cont.) ► Project team developed complex models of Symbol’s enterprise architecture ► Each element (system, database, application, etc) was depicted, along with its use (upstream and downstream) and interactions with other systems ► Integration team used the information stored in System Architect to evaluate the existing landscape and develop a plan for integration into Motorola’s Enterprise Mobility business unit
