4 Challenges to Asset Modernization We want to reuse key parts of our mainframe applications in a SOA. Where do we start? We've accumulated decades of changes to our valuable applications, but we don't have reliable documentation of them We've outsourced our application development; how do we keep intellectual control of our applications? We can't be sure how changes in one part of an application will affect other parts, so maintenance is difficult and dangerous Our applications staff are retiring or moving on, and we are losing the subject matter expertise We need to change our applications to address industry or government mandates... and it's going to take a lot of time and money The cost to enhance our applications are holding back top-level business growth We can't afford to rewrite our mainframe applications as new web applications 2006 IBM Corporation 4

5 The Value of Rational Asset Analyzer Accelerate project delivery in response to business drivers Reduce risk Increase productivity Improve quality of application changes Gain intellectual control of applications Gain transparency into outsourced development Customize RAA to organizational processes and IT environments 2006 IBM Corporation 5

10 Rational Asset Analyzer Counts & Metrics Gain control of your assets & know what you have Identify the breadth of technologies currently used in the enterprise using a dashboard or report view Understand the quality and complexity of your assets Use the Errors view to identify missing resources Error rate is an indication of validity of data; also includes tools to help reduce the error rate 2006 IBM Corporation 10

11 Rational Asset Analyzer Application Understanding Quickly understand code with little or no documentation, and relationships across the enterprise Group artifacts into user-defined groups called Applications to limit scope to area of interest Use various types of diagrams for understanding how the application hangs together Use annotations to capture knowledge from SMEs e.g. Business function, description, etc. Create user-defined relationships for situations where relationships cannot be determined through static analysis Perform enterprise-level keyword searches 2006 IBM Corporation 11

12 Rational Asset Analyzer End to End Impact Analysis Reduce time to market & risk of downtime by understanding change impact upfront Reduce time to determine scope of change whether for new enhancements, or even maintenance efforts View the metrics for impacted artifacts to determine the risk of change i.e. cyclomatic complexity, lines in file, etc. Traverse user-defined relationships to determine impacts across platforms i.e. follow dependencies from mainframe to J2EE and back. Create a bill of materials of impacted artifacts by evaluating the details page 2006 IBM Corporation 12

13 Rational Asset Analyzer Extensible Framework Tailor RAA to your organization s needs Access RAA s wealth of information using standard web services Add the support for languages not currently supported using RAA s documented import file format Extend RAA with user-defined metrics & counts Create custom queries, and optionally include them as actions on pages Create your own Web 2.0 applications and access RAA information using RAA s REST interface 2006 IBM Corporation 13

14 Rational Asset Analyzer Scalability The ability to start small and scale up to enterprise-wide usage RAA is built on the highly scalable Websphere Application Server and DB2 products It has the potential to handle hundreds of millions of lines of code * Application Server You have the flexibility to start with a small team (10-15 users), or scale up to handle source of the entire enterprise * Since RAA is browser-based, administration costs are minimized Client machines do not need to be managed & updated Scaling up is as simple as giving additional users access * Scalability is dependent on the hardware and level of complexity of source code 2006 IBM Corporation 14

16 Product Positioning Product Focus Description Rational Asset Analyzer Rational Developer for System z Rational Asset Manager Rational Software Analyzer Accelerate Project Delivery Developer Productivity Governance & Reuse in Development Process Manage Code Quality & Policies Gain insight into enterprisewide applications & find dependencies across applications Leverage an integrated development environment to develop and debug applications & create services Manage, govern and share assets in the development process Manage code quality through development & build 2006 IBM Corporation 16

17 Rational Asset Analyzer Synergies RAA enhances value of other tools Rational Developer for System z (RDz) Combine productivity gains of RDz with the enterprise-level insight in RAA to minimize time-to-market and minimize risk due to lack of visibility into impacted artifacts Rational Asset Manager (RAM) Use RAA to identify artifacts/assets of interest, then use RAM to publish those assets for reuse, and manage/govern the development process around changes to those assets. That is, jumpstart RAM deployments for a quicker ROI. Use RAA to perform deeper level analysis for change requests coming in to RAM IBM Corporation 17

20 Questions? 2006 IBM Corporation 20

21 Positioning Rational Asset Analyzer (RAA) & Rational Software Analyzer (RSAR) Draft Request Business Manager Approves System Planning Approves Develop Business Requirements RAA Inventory Information Services Review Feasibility Study Detailed Analysis (SOW) Information Services Approval Business Approval Development Activities Unit Test & System Test Build Production Update Inventory RAA: Accelerate project delivery Understand application artifacts and scope of proposed change request Create project estimates, system diagrams, and other input to project manager s work breakdown structure Integrate with SCM to create application snapshot at specific code level (usually QA or production) Contributes to development by performing impact analysis to ensure that all impacted artifacts are updated. RSAR: Manage code quality through development & build Manage various dimensions of quality through the development process Gain visibility into adherence to quality standards and policies Find errors earlier in the development cycle Integrate with BuildForge to create buildlevel snapshots of quality *Does not support COBOL, but will do so in a future release 2006 IBM Corporation 21

22 Value of Rational Asset Analyzer Gain intellectual control of your applications discovery relationships / dependencies application and program structure Improve quality of application changes Enable developers & teams to work above their experience level Document your applications from the code itself Improve change management / governance / compliance processes Incorporate into existing IT operational processes 2006 IBM Corporation 22
