    1. 1. Take advantage of new trends in agile:Iterationless Kanban and ContinuousDeploymentLean Startup Meets Lean Development: A Case StudyErik Huddleston 2
    2. 2. Who Am I?• CTO, Dachis Group • World’s largest Social Business Strategy Company, one of the world’s largest group of Preferred Facebook Developers, Social• Ran Development, Product Management, Operations at SaaS Business Intelligence technology companies from startups to hundreds of millions in revenue • AustinVentures backed, $30M B round in January• Teams from 5 to hundreds • 11 Acquisitions, 10 Offices, 6 Countries• Recognized Agile Practitioner (Gartner case study, regular conference speaker)
    3. 3. What am I going to talk about?• Latest trends in software development: Lean Startup and Lean Development• How Dachis Group has successfully integrated these, including process specifics and the technology we used to do it• Three key areas of focus if you want to do the same• Broadly applicable key learnings and insights from our process and development technology innovation Note: Reading material will be available in the appendix. The slides will be available online.
    4. 4. The Lean Startup Movement and theLean Development Movement are the twomethodologies at the leading edge of innovation inSoftware DevelopmentLean Startup is a concept coined (and trademarked) by Eric Ries. Ries Lean software development is a translation of Lean manufacturing and Lean IT principleswrites that lean startups are born out of the following three trends: and practices to the software development domain. Adapted from the Toyota Production System, a pro-lean subculture is emerging from within the Agile community. 1. use of free and open source software, 2. application of agile software development methods, and Lean development can be summarized by seven principles, very close in concept to lean 3. ferocious customer-centric rapid iteration, as exemplified by Steve manufacturing principles: Blanks Customer Development process[1]. 1. Eliminate waste 2. Amplify learning 3. Decide as late as possible 4. Deliver as fast as possible 5. Empower the team 6. Build integrity in 7. See the wholeDefinition Sources: Wikipedia 5
    5. 5. Both appear to be the heir apparents for bothstartups and new ventures inside of existingcompanies.That means everyone who develops softwareneeds to know how to implement them together. 6
    6. 6. Unfortunately, while everyone prescribes usingan Agile or Lean development methodology with"Lean Startups", very little is available to describeHOW the two intersect 7
    7. 7. At Dachis Group, we have married the two.There are three key areas of focus for others wantingto do the same• Building a Backlog• Structuring your Kanban Flow• Continuous Deployment 8
    8. 8. Qualifying Dachis Group, YMMV• Large Scale SaaS Development, Rapid Growth• Time/Place shifted development (9 time zones, 8 countries)• Bleeding Edge Technology, Rapidly Evolving Market YMMV: your mileage may vary. (idiomatic) It may work differently in your situation, or be different in your experience. 9 http://en.wiktionary.org/wiki/your_mileage_may_vary

    11. 11. Building the Backlog: How we did it• Housed in JIRA/GreenHopper• MVP features modeled in Epic/Feature/Story hierarchy • Epic: Product X MVP Implementation • Feature: Login • Story: "As a user I would like the ability to reset my password so that I can recover from a forgotten password without emailing support."• Architectural Runway and Spikes captured during feature planning sessions 12
