Genius.com Overview • Software-as-a-Service • Sales & marketing products • Languages – PHP – Perl – Java – C# – JavaScript • MySQL • ExtJS & YUI 2

The Bad Old Days • May 2007 – Unreliable release dates – Low quality – Unmaintainable code – Poor ops/dev/QA relationship – 0% test coverage 3

What Was Wrong? • Requirement waterfall • Assigned silo development • No automated testing • Developing on quicksand • No progress tracking • Dev & QA separation • Release piling 4

Agile Misconceptions 6

Agile Misconceptions “We’re iterative so we’re agile” “There’s no time for architecture design” “Our features are too big to fit into sprints” “Our code can’t be unit tested” “The daily meeting is a waste of time” “Agile is an excuse to micro-manage” 6

Genius.com Agile Milestones ... September 2009 Split into 2 teams January Hired brilliant build engineer May Hired supportive VP April New collaborative workspace 2008 March Introduce Scrum board February Scrum Master training December Start of on-time release streak October 2007 August Co-located dev & QA Nightly builds June First unit tests April First “iteration” 7

Hiring • Intelligence over Experience • Cultural fit • Enthusiasm • Motivated • Referrals • From RIT or HMC 8

Collaboration • Encourage non-work interaction • Team breaks story into tasks • Collective decisions • Self-assigned work • Co-located product management • Remove barriers • Hold team responsible • Conducive workspace 9

Daily Standup 13

Scrum Board • 5 columns • Swim lanes for stories • Stories are color coded • Team commits to stories every 2 weeks • Production and previous sprint bugs • Team decides order of stories • Can only be on one open story • Don’t move on until entire story is done 14

Definition of “Done” • Task – Unit tests written and run – Code and tests checked in – QA verify it’s bug free – UI tests written and run – Security code review • Story – Product management sign-off – Potentially shippable – No open non-validated tasks – No technical debt 15

Prioritized Backlog • Maintained by product management • Aggregation of all features requested (users, sales, marketing, operations, developers, QA, etc) • Prioritized by product manager based on input • Higher priority = increased definition and granularity • Meet & greets w/ the team • Phrased as user stories “As a marketer I want to be able to schedule an email to go out in the future so that I don’t have to be at my desk for the email to go out at a specific time” • Acceptance criteria “1 month maximum, 1 hour minimum” • Everyone needs to understand tradeoffs 16

Process Evolution • May 2007 – Unreliable release dates – Low quality – Unmaintainable code – Poor ops/dev/QA relationship – 0% test coverage 18

Process Evolution • May 2007 • December 2009 – Unreliable release dates – 13 consecutive on-time – Low quality major releases – Unmaintainable code – 90% reduction in production bugs – Poor ops/dev/QA relationship – 72% unit test coverage – 0% test coverage 18
