WHYWe believe we can change web traffic analytics

HOWWe collect data from millions of users and analyse it

WHATWe created several websites and services that shows the

analysed data from various angles

OUR CHALLENGESmove fast - we need to develop new features quicklyget quick feedback - we need to know if our customerslike our product and apply changes fastfocus on value - we need to create a company-wide focuson the things that matters

OUR PROBLEMSour business is constantly evolvingwe are in a competitive marketwe are growingour architecture is evolvingdevelopment can take a lot of timeour load is increasingwe have more quality issues

WHAT CAN WE DOimprove communication and tasks managementstandardizationscalable architecture (human-wise and production-wise)faster and better quality assuranceautomate repeating processes

OUR GOALSWE SHOULD AIM FOR

staying focusedbeing flexibleshortening feedback loopsbeing quality oriented

AGILE METHODOLOGYADOPT CHANGE

Focus

small featuresiteration start / stand-up meetings / retrospectivesdefinition of readyless paper, more talktransparent

Flexible - quickly adopt to change

Short Feedback Loop - release when done

Quality Oriented

QA built indefinition of done

CVS - GITBRANCH FAST, MERGE FAST

Focus - isolate your environmentFlexible - working together without interruptionsShort Feedback Loop - commit often, rebase oftenQuality Oriented - test locally before commits

DOMAIN DRIVEN DESIGNEVOLVE TOGETHER

Focus

ubiquitous languagestructured code and logicAPIs as domains

Flexible - evolving model

Short Feedback Loop - allows testing domain logic first inisolationQuality Oriented

test locally before commitsNo SPOF

CODE STANDARDIZATIONUNITE AND GAIN

Focus

use common practices when possibleenjoy the open source community

Flexible - developers mobility

Short Feedback Loop - tooling that guide the developer

Quality Oriented - part of the build process

TDD/BDDQUALITY FIRST

Focus

focus on the taskstakeholder and developer work together

Flexible - allows safe changes

Short Feedback Loop - tooling that guide the developerQuality Oriented - quality before implementation(queuing theory)

TEAMS BASED ONPROFESSIONGROW TOGETHER

Focusdo one thing goodadvantage of size

Flexible - assign developers to tasks based on workloadShort Feedback Loop - change, test, spread acrossproductsQuality Oriented - use tools to guide and enforcestandards

OWNERSHIP BASED ONPRODUCT

OWN YOUR WORKFocus - distributed responsibilityFlexible - define responsibilities based on actual productShort Feedback Loop - alert the right personQuality Oriented - production is part of the process

A/B TESTING AND FEATUREFLAGS

STOP GUESSINGFocus - focus on resultsFlexible - experimenting several options at onceShort Feedback Loop - metrics tells what worksQuality Oriented - reduce risk in production

CONTINUOUSINTEGRATION /DEPLOYMENT

SHIP FAST AND SAFEFocus - release is not a ceremonyFlexible - develop mvp, ship, monitor, repeatShort Feedback Loop - (almost) instant feedbackQuality Oriented - safer, less human error prone

MONITORINGCONTROL PRODUCTION

Focus - results, not guessesFlexible - monitor everything with minimal impact onproduction serversShort Feedback Loop - real time dataQuality Oriented - detect errors before customers do

GOOD LUCK!
