  • 1. Business improvement by Enterprise Agile Process
  • 2. (About Ravindra)
    • Electronics and communication engineer from Rajasthan university
    • Pursuing MBA (IT) from symbiosis international university
    • Did project on SAP practice operations management from fujitsu consulting india private limited
    • 06/07/09
    • Ravindra EAP
  • 3. EAP
    • 06/07/09
    • Ravindra EAP
  • 4. What is EAP?
    • A "balancing act" to achieve Agile Reusability an standardize application development for the enterprise.
    • A collection of agile practices that support the Agile Manifesto
    • Manage several applications simultaneously
    • Encourage the creation and use of reusable components at all levels of scale
    • 06/07/09
    • Ravindra EAP
  • 5.
    • 06/07/09
    • Ravindra EAP
  • 6. Roles
    • Application Developers
    • Coaches/Architects (only when technical guidance and agile practice guidance is needed, otherwise NOT required)
    • Team leaders/Scrum masters
    • Support: Systems, CM, testing, etc.
    • Shared Resources team
    • Shared Resources developers
    • 06/07/09
    • Ravindra EAP
  • 7. (continued)
    • Enterprise Architect (needed only if Shared Resources team developers cannot articulate a vision)
    • Shared Resources team leader
    • Project/Application Sponsors
    • Clients: business process owners, external clients
    • 06/07/09
    • Ravindra EAP
  • 8. Project Management
    • Break Multi-Application Project In Sprints == 1-3 month Iterations.
    • Break the lifecycle of each individual project into 1 month Sprints (Iterations). Use the All-At-Once Model to develop software: Analysis, Design, Implementation, Testing and finish with an executable release
    • Master Product Backlog – Manage everything there is to do through a master prioritized list. This list includes: features, upgrades, release management, configuration management, adopting new tools, etc.
    • 06/07/09
    • Ravindra EAP
  • 9. (continued)
    • Application Product Backlog - Each application contributes to the overall Product Backlog
    • Shared Product Backlog - In addition shared Product Backlog contributes to the overall product backlog
    • Do daily internal releases to integration boxes
    • Test each System through banks of unit tests per application
    • Release the product to external customers after a few internal iterations
    • 06/07/09
    • Ravindra EAP
  • 10. (continued)
    • Sprint Planning Meeting: At the beginning of an iteration, get everyone together in one room, prioritize the features of the project and decide which features go into that Sprint == Iteration
    • System and Application Spring Planning Meeting
    • Sprint Backlog. Break Product Backlog chosen for Sprint into 2-4 hr tasks. Evaluate timelines with these estimates. Recalculate timelines every day after getting the status of completion from the Daily Scrums.
    • 06/07/09
    • Ravindra EAP
  • 11. (continued)
    • Sprint Review Meeting. Give a Demo to the customer after each Sprint. Get customer feedback and reintroduce the feedback into the Product Backlog
    • Scrum of Scrums - frequent meetings, once or twice a week, at the same time and place, where team leaders share information about the status of their applications
    • Daily Scrums - Daily 15 min. meeting, at the same time and place, where resources report 3 things:
      • 1) what they worked on for the last 24 hrs.
      • 2) what issue they have
      • 3) what they will be working for the next 24 hrs.
    • 06/07/09
    • Ravindra EAP
  • 12. (continued)
    • Visible Status - keep a visible chart with the stories and their completion status. Hang it on the wall! (document)
    • Sustainable Pace - Practice long-term sustainable development. (In most cases this means don’t exceed 40 hr. of work in the US or 35 in Europe)
    • Pair Programming. Use pairs for mentoring, collaboration, and the creation of X-functional team
    • Collective Ownership - every developer is responsible for the deliverable and must be able to change, upon coordination, any component of the system
    • 06/07/09
    • Ravindra EAP
  • 13. Analysis
    • CRC Stories - short UCs on CRC (5’’ by 3’’) cards for all Use Cases … then play cards with the customer to decide which features will be implemented! (document)
    • Use Case docs only for more complicated behavior (document)
    • On-Site Customer - Developers don’t know business rules and business needs…… An on-site customer, or at least an Available Customer is a key priority
    • 06/07/09
    • Ravindra EAP
  • 14. Testing
    • Test first – Write the a unit test for the functionality you are developing before you write the component and maintain the test while you do development.
    • Unit Test - Create and maintain a Unit Test for every major component of the system
    • Application Regression Testing - base Regression Testing on Unit Tests. Any other way to do it will duplicate resources and knowledge requirements.
    • Multi-application/system regression tests.
    • 06/07/09
    • Ravindra EAP
  • 15. Architecture
    • Metaphor - Simple story of how the whole system works (document)
    • Simple Design - Don’t add features you are not needing now (YAGNI)
    • Layered Architecture through Patterns
    • Strong architectural Style, preferably enforced with/through Frameworks
    • Refactoring - Redesign without changing the behavior. Refactoring can provide great efficiency gains.
    • Coding Standards - all code must look as if it was developed by the same developer
    • 06/07/09
    • Ravindra EAP
  • 16. Layered Architecture
    • Enterprise Agent Network (servlet-based PAC/MVC framework)
      • applications
      • workflows
      • visual components
      • services
      • transactions
      • business objects
      • architectural services
    • 06/07/09
    • Ravindra EAP
  • 17. Release Management
    • Continuous Integration - Integrate and build the system many times a day.
    • Release architectural layers in inverted order
    • Use versions to use and simultaneous develop multiple new code bases
    • 06/07/09
    • Ravindra EAP
  • 18. Values and Beliefs
    • Commitment - Care for the project
    • Focus - Concentrate on the task at hand
    • Openness - Problems, status and plans
    • Respect - for other team members and customers
    • Courage - Admit faults, request necessary things, talk about things as they are
    • Share Knowledge - technical and non-technical
    • 06/07/09
    • Ravindra EAP
  • 19. Examples
    • William Mercer, 3 applications in production
    • Nike Securities, 5 application in production
    • Caremark, 15 applications in production
    • 06/07/09
    • Ravindra EAP
  • 20. Conclusions
    • Agile Development is a paradigm shift for software development
    • EAP is easy and cheap to implement
    • EAP can save millions of dollars through reusable components
