Choose the tool.Then follow the evidence.
Browse the current Capybara Case Files by the kind of problem you need to solve. The library is intentionally small: four techniques, each explained visually and built around a different way of thinking.
5 Whys
Follow a causal chain past the first explanation until you reach something useful and evidence-based.
OPEN CASE #001 →Ishikawa / Fishbone
Map plausible causes broadly before evidence narrows the investigation and prevents tunnel vision.
OPEN CASE #002 →Pareto Analysis
Rank recurring issues by frequency or impact so effort starts where the largest share of the pain sits.
OPEN CASE #003 →Kepner–Tregoe
Structure complex choices and investigate deviations by making criteria, risks and evidence explicit.
OPEN CASE #004 →FIELD GUIDES_
Short, practical notes on when each technique helps, where it fails, and what evidence should do next.
FOLLOW THE EVIDENCE_
The library helps you choose a thinking tool. The technique still needs facts, observations and verification. problem.me should make thinking clearer — not manufacture certainty.
