Experience RealisationHand-dominant: how does it behave?

Experience Realisation is where the design becomes something a person can encounter. The problem framed in Problem Framing and the values shaped in Value Shaping take on a form that can be held, used, tested, and assessed by a real person under real conditions.

Experience Realisation leads with Hand, and the work turns generative. You produce an actual artefact, with actual behaviour, at an actual level of craft.

Experience Realisation’s scope is usability and desirability. A product can be highly usable, clearly navigable and consistent with the user’s mental model, without being desirable. It can be beautiful and compelling without being usable. The work of Experience Realisation is making one artefact that is both.

Three aspects structure Experience Realisation.

• Form, What is the actual artefact or system?
  Form is the actual designed artefact, at enough fidelity to be judged. A wireframe only approximates it, and a prototype only suggests it. Form is the specific configuration of shape, layout, type, colour, spacing, and interaction that makes intent perceivable. Norman’s account: good form encodes affordances, communicates feedback, supports the user’s mental model, the user knows what to do without instructions, because the form tells them.¹ Form that works this way is largely invisible. Form that fails makes its failure immediately apparent.
• Behaviour, How does it behave, feel, and respond?
  A designed artefact exists in time as well as space. It moves, responds, transitions, loads, fails, recovers. Behaviour occupies the interval between a user’s action and the system’s response, and that interval is where trust is built or broken. Precisely timed behaviour produces the feeling that the system understands what the user is trying to do. That feeling is designed, and good form alone will not produce it.
• Craft Bar, Does it work at the level of craft?
  Sennett’s framing: craft is the discipline of doing something well for its own sake, measured by an internal standard, with external validation beside the point.² In design, the craft bar is the execution threshold below which the intent cannot reach the person it was made for. Below it, poor execution creates friction that obstructs the meaning shaped in Value Shaping. The user encounters the execution result, but the design never gets through.
