Triangulation vs conflict resolution vs evidence synthesis

Table comparing triangulation, conflict resolution and evidence synthesis by the question each answers, its scope and when to use it.
Three different jobs that all get called synthesis. Only the last one covers many studies over time.

A comparison of three operations researchers often lump together as synthesis. Triangulation checks whether methods agree on one question at one point in time, conflict resolution settles a clash between two sources, and evidence synthesis combines everything learned across many studies into one rated conclusion. Use it to check which one your team is actually doing.

Where this appears

What's in this reference table

OperationQuestion it answersScopeWhen to use
TriangulationDo different methods agree about this one question, right now?Several methods, one study or programme, one point in timeValidating a single finding before acting on it
Conflict resolutionTwo datasets disagree. Which is right, and why?Two specific sourcesA qual finding contradicts a quant one
Evidence synthesisWhat does everything we have learned add up to, and how sure should we be?Many studies, many methods, across timeStrategy, prioritisation, any decision bigger than one study
