Testing
is like CSI
--- Cem Kaner

CRIME SCENE INVESTIGATION
TESTING IS LIKE CSI
MANY tools, procedures, sources of evidence.
• Tools and procedures don't define an investigation or its goals.
• There is too much evidence to test, tools are often expensive,
so investigators must exercise judgment.
• The investigator must pick what to study, and how, in order to
reveal the most needed information.
Checking Is Confirmation.
Testing Is Exploration and
Learning.
--- Michael Bolton
