Failure is not an option. It’s the CRO Roundtable Roundup!

Thanks to Matt Beischel, Shiva ManjunathCraig Sullivan, and David Swinstead for joining us. Want to get in on the action and talk with other cool CRO people? Then you should probably…

One Sentence Takeaway

I’m a busy person; give me the TL:DR

Prioritize clear experimentation maturity: emphasize data quality, bias mitigation, and tailored prioritization over one-size scoring.

The Notes

What we discussed this week

  • Intent framework for mapping data behaviors
    • X-axis: data-informed versus data-driven behaviors
    • Y-axis: good intention versus bad intention
    • Plot specific behaviors across the framework
  • Measurement quality problems caused by perverse incentives
    • Example: bonus tied to bounce rate resisted fixes
    • Data quality concerns from dirty instrumentation
    • Checkbox implementation on tickets harms data
    • You should audit and validate tracking data regularly
  • Benchmarking experimentation maturity
    • Break behaviors into tactical maturity questions
    • Tailor maturity model to organizational context
    • Integrating behavior scores into maturity models
  • Prioritization frameworks, scoring, and voting mechanics
    • Comparing frameworks: PIE, ICE, CXL, PXL, and bespoke builds
    • Questioning the validity of numeric “probability of winning” estimates
    • Use objective scoring whenever possible
    • Live team voting tools
    • Flicker as a subtractive prioritization factor
  • The role of AI in predicting test outcomes
    • It is more-or-less impossible to assign true win probability
  • Misleading metrics
    • Time-on-site is an unreliable engagement metric
    • Use a heartbeat/event approach to measure actual focus
    • Bounce-rate does not have a standard, technically consistent definition
    • Sample-size and metric collection limitations

The Quotes

Standout quips from this week

“My favorite one was some guys that wouldn't let me fix Google Analytics because their bonus was tied to the bounce rate on the site.”
"If you don't like your job, get a new one."
"Maturity models only work if they’re built for your actual organization, not someone else’s template."
