Day 58 / 100 · Evidence · Qual + quant together

Numbers say what. People say why.

Data at scale shows patterns but not reasons. Conversations show reasons but not scale. You need both.

Quantitative

Scale · Blind To Reasons

  • What happened, how often
  • Across every customer
  • Trends and comparisons

Qualitative

Depth · Small Samples

  • Why it happened
  • How it feels
  • The context around it

Quant Spots

Something changed, and where.

QUAL EXPLAINS

Why it changed, in customers' own words.

QUANT CONFIRMS

Whether the fix worked at scale.

Spot with numbers. Understand with people.
