chunksGives you time to thinkHelps transition to other SWITAs,IGS,ITS,AIM Services&Solution AssuranceHelps you remember where you left off with a customer!,BUSINESS CONTEXT DIAGRAM:,Helps define the scope of the projectHelps you understand the customers business processes,leading to a better solutionHelps you understand the relationships between the target business entities and processes and other entities/processesIdentifies potential system interfaces,CURRENT ORGANIZATION:,Helps qualify the opportunity:are we in at the right level of the organization?Identifies(potential)sponsors,power sponsors,and enemiesIdentifies persons who should be involved in the sales process and what their roles should be Identifies additional opportunitiesHelps identify system interfaces,BUSINESS PROCESS ROADMAP:,Helps you understand the customers current and proposed business processes,leading to a better solutionHelps you build credibility with the customer by demonstrating an understanding of their key business processesHelps you more effectively communicate with the customer and the client team regarding the customers business objectives,ENVISIONED GOALS&SSUES:,Documents you agreement with the customer on their goals,issues,and CSFsProvides a basis for assessing the success of the projectProvides high-level functional requirements for your use in designing the solutionHelps It see the big picture(theyre usually focused on immediate deliverables),IT STANDARDS:,Provides“givens”to be considered in your solutionHelps you eliminate unfeasible options up frontIdentifies competitors and opportunities for competitive“replacements”(e.g.Oracle-DB2 UDB)Helps ID skills and education requirementsHelps ID current assets,CURRENT IT ENVIRONMENT:,Guides you architecture decisionsIdentifies candidates for re-useProvides a starting point for the to-be architecture pictureIdentifies system integration requirementsHelps define transition/release strategy to minimize riskHelps determine the sophistication of environment,PROJECT DESCRIPTION:,Communicates the projects goals to all parties;answers the question:“what are we doing on this project and why?”Helps ensure agreement to the project goalsIdentifies issues early on in the projectProvides a basis for development of the architecturabas solution,SYSTEM CONTEXT DIAGRAM:,Identifies scope boundariesDefines interface requirementsHelps identify potential interface solutions,USE CASE MODEL:,Provides functional requirements for development of your solutionProvides a process for validating a proposed solution Helps in planning a PoCPrioritizes/categorizes system capabilitiesHelps define release strategyIdentifies user and system interfacesUse Case Description helps describe(in text)the systems responsibilities.,NON-FUNCTIONAL REQUIREMENTS:,Documents critical requirements like performance,security,and availability that must be met by the proposed solutionHelps validate the proposed solutionProvides a basis for estimating the size and cost of the proposed systemFirst sign of potential software product requirements,VIABILITY ASSESSMENT:,Helps you determine the probability of success for a proposed solutionHighlights issues and risks early on,when they are more easily resolved,ARCHITECTURAL DECISIONS:,Provides your rationale for including IBM content in the solutionLets you position IBM content to customers within an architectural contextCommunicates the foundation for your choices to the implementors such as IGS,ARCHITECTURE OVERVIEW DIAGRAM:,Communicates the architecture solution“vision”to all partiesIdentifies the IBM and third-party elements of the proposed solutionProvides input to follow-on design and implementation workThis is where themagichappensUse several views depending on the audience,AVAILABLE ASSET LIST:,Helps you justify your choices to customers and other partiesHelps you keep track of your findings and thought process when researching optionsHelps avoid an RFPMay include assets found in other projects within the same customer,COMPONENT MODEL:,Helps document the solution components and their relationshipsIdentifies the components needed on the Operational ModelHelps validate a complex solution,OPERATIONAL MODEL:,Helps validate a solution by showing how non-functional requirements are satisfiedHelps provide early cost and sizing estimates for the proposed solutionHelps plan for the implementation of the first project or PoC,ARCHITECTURE BRIEF:,Helps you quickly identify products that fit the customers requirementsHelps you identify product issues that may affect the projectHelps you determine skill requirements that affect your recommendations for products or services,
