WHERE WE STARTED

#agility2016

Scope of Tagging at HomeAway

Over 30 Different Domains

2 Dozen Different Tag Vendors

#agility2016

Organizational

• Marketing owned tagging implementation• There were 2 developers who reported up through Marketing

Org• Developers had no ties to Engineering Org

• This meant velocity often won over scalability, stability, and performance

• No backing from Engineering Org• Engineering Org had little insight into tags on the site or when they

were updated• This led to surprise when things would break

6

#agility2016

Large Backlog of Tagging Requests

• Slowed the rollout of marketing campaigns• Limited the ability of campaigns to perform as effectively as

possible• Increased the need for higher and higher development

velocity

7

#agility2016

No Quality Assurance (QA) Testing

• Tagging traditionally doesn’t get the same QA attention as product code

• Production outages due to bugs in our code• Any site downtime means lost revenue

• Regressions of previously fixed issues• No formal release/change log to clearly

identify what caused an issue• Tagging bugs led to data loss
