Objective 1.5 · Domain 1 · 17% of the exam

Apply decomposition techniques for complex problem solving

Decomposition: breaking a task too large or too vague for one call into steps that can each be prompted, tested and evaluated. Watch for the distinction between decomposing for accuracy, where each step becomes easier to get right, and decomposing for observability, where each step can be inspected when the whole thing goes wrong. Stems usually signal which one they care about.
