Abstraction Laddering is a problem-solving technique that moves a problem statement up (toward more abstract goals) or down (toward more concrete implementations) a hierarchy of levels to reveal new solution spaces. Developed in design thinking and communication theory, it breaks problem-definition fixation by showing that most problems can be stated at multiple levels of abstraction — each revealing different and complementary solutions.
Constraint Relaxation is a problem-solving technique that identifies the assumptions and restrictions implicitly or explicitly limiting the solution space, then systematically asks "what if we removed this constraint?" to open previously invisible options. Many constraints that appear fixed are actually assumed fixed — relaxing them reveals solution approaches that never surfaced within the original bounded space.
Design Thinking is a human-centred innovation process developed at Stanford's d.school that moves through five phases — Empathise, Define, Ideate, Prototype, and Test — to solve problems by deeply understanding users before generating solutions. Popularised by IDEO and adopted by IBM, Google, and Apple, it is the dominant framework for product innovation, service design, and organisational problem-solving that prioritises desirability (human need) alongside feasibility (technical possibility) and viability (business case).
Reframing is the cognitive technique of changing the interpretive framework through which a problem is viewed — not changing the facts, but changing how they are understood, structured, or evaluated. Rooted in cognitive psychology and design thinking, reframing breaks the implicit constraints that most problem definitions carry and opens solution spaces that are invisible from within the original frame.
Storyboarding is a visual narrative technique originally developed at Walt Disney Studios in the 1930s that uses sequential images (with optional annotations) to map out a story, experience, or process before it is built. In product design and service design, storyboarding makes abstract user journeys concrete, reveals friction and delight points, communicates vision across teams, and identifies failure modes early. It is one of the most powerful tools for aligning cross-functional teams around a shared understanding of experience design.
