  • Show what’s been done – roles. Process adaptations: PMC within Rational to ensure project funnel IBM product delivery process. Print them on DVDs. Agile
  • Common agile practices: iterative, reflect, adapt, incremental, feedback Practices inspired by agile practices, scrum, xp, some custom ones, that work for us
  • Distributed development: planning an iteration takes longer
  • Chickens – give feedback, also support dev team (pigs) doing the complete job. Light adaptation – in scrum – architects on the pigs side usually. This time we have them in chickens becoz ibm architects get info from customers, present to customers, very customer focused. At the same time building things.
  • 2 reasons for these slides – 1. use terminology well know. 2. trying to apply things as they should. Less developers asking for strange things, etc. apply as much as agile as poosible. It’s a big change for IBM, but we are willing to adapt agile, not mixture. We’re doing what we can to become more agile. For a while, we mixed 2 teams, so all coming from RTCz and RTCp. Originally 2 project owners. Now have just one enterpirse extension team. Still have 2 project owners. To ensure actual release. In 3.0.1 only Guy -> from NZ. Guy Slade.

  • Jazz - transforming software delivery
    • Jazz is…
      • Our vision of the future of systems and software delivery
      • A scalable, extensible team collaboration platform
      • An integration architecture enabling mashups and non-Jazz products to participate
      • A community at Jazz.net where Jazz products are built
      • An evolution of our portfolio over time
    c Rational Offerings Third party Offerings Business Partner Offerings Jazz is a platform for transforming how people work together to deliver greater value and performance from their software investments.
  • Essential attributes of Jazz Deliver real-time insight into programs, projects and resource utilization. Report Automate non-creative tasks with automated processes and workflows Automate Improve knowledge and practice maturity with an environment that develops individual and team talent. Deliver transparency of teams and projects for continuous, context-sensitive collaboration Collaborate
  • CLM supports effective team collaboration across lifecycle Quality Professional Product Managers Collaborative Lifecycle Management Project Team Developers Quality Management Requirements Development
  • The distributed Jazz Team
  • Our Reality – Agile Scaling Challenges Domain Complexity Straight -forward Intricate, emerging Compliance requirement Low risk Critical, audited Enterprise discipline Project focus Enterprise focus Technical complexity Homogenous Heterogeneous, legacy Flexible Rigid Organizational complexity Team size Under 10 developers 1000’s of developers Co-located Geographical distribution Global Organization distribution (outsourcing, partnerships) Collaborative Contractual Agility @ Scale
  • Team organisation
    • We work in both component and feature teams
    • Component team
      • Dependencies between adoptions tracked using Adoption Items
    • Feature teams
      • Execution tracked in the plan items
    Feature Team Component Team Responsible for complete customer feature across products/components Responsible for only part of a customer feature Minimized dependencies Dependencies between teams leads to additional planning Iterative development More sequential development due to adoption sequence Optimizes customer value Optimizes for a particular component
  • Scrum applied
    • Development process
      • Based on the standard Scrum process template
    • Minor process adaptations
      • New role: PMC ( Project Management Council - based on Stakeholder role)
      • New Minutes work item
      • Updated permissions

        • Limited operations for externals
      • New automatic tasks when joining a team
        • [Joining a Team] Update your calendar with your Scheduled Absences
        • [Joining a Team] Update your Work Environment
  • Adaptation of development practices iterative development API first end game retrospectives always have a client continuous integration community involvement new & noteworthy adaptive planning continuous testing consume your own output drive with open eyes validate reduce stress learn attract to latest transparency validate update feature teams show progress enable validate live betas feedback sign off End of iteration demos/reviews Ranked Product Backlog Burndown Stories Daily Standup independent testing exploratory testing Definition of Done
  • Sprint planning detailed
    • First days of each Sprint
      • Get Sprint directions from Product Owner
      • Analyze Stories with the Architects
    • All Scrum team members are involved
    • 1 Sprint planning per Scrum team
    • Check Sprint time budget
      • Plan/verify absences in RTC
    • From Product Backlog ...
      • Query Work items
      • Team members try to fully understand User Stories with the help of the Architects
      • Give estimates using the Planning Poker technique
    • ...To Iteration Plan
      • Fill Sprint backlog with selected Stories based on team velocity and priorities
  • Our Rhythm endgame release M1 plan develop stabilize 4-6 weeks warm-up retrospective initial release plan decompression M2 plan develop stabilize … plan develop stabilize sign-off sign-off sign-off 4-6 weeks 4-6 weeks fix - spit & polish test fix test Retrospective New&Noteworthy End of iteration demo
