 The practice team wasn’t the same as the game time team.  Segregated technical and business functions  Development  Operations (Operational Waterfall)  Infrastructure Ops  Product Ops  Product technology under the sun  Solaris, Windows, Linux  Apache, IIS, TCServer, etc.  Oracle, DB2, SQL Server  How we got better  We read and we studied.  Created a self-improvement project  2 week

the next six-month release.  DO epics and user stories to concisely define the desired system functions and provide the foundation for Agile estimation and planning. o They describe what the users want developers, testers, and other stakeholders have a clear and agreed-upon understanding of the desired functions. They offer a far more dynamic approach to managing requirements than large requirements documents

work flow streamline interdepartmental communications, and effectively serve the other business functions at Parts Unlimited. Key Concepts The Three Ways [2] The First Way emphasizes the performance

OF DAILY WORK i. Create infrastructure to make it easy for Dev or Ops to create telemetry for functions built ii. Generate graphs with overlays of production changes iii. Tools – StatsD, JMX, codahale

developing the application iii. QA – team responsible for ensuring feedback loop exists to ensure functions as desired iv. Operations – the team responsible for maintaing the production environment and
