Functional skill · Working draft
Design the dialogue between people and products.
Interaction design gives structure to what people can do, what the system does in response, and how both sides understand what happens next.
It brings together user intent, information structure, behaviour, states, language, feedback, time, accessibility, and technical constraints. Strong interaction design makes complexity understandable without pretending it does not exist.
What the skill looks like in practice.
Orientation and information architecture
Make location, available paths, labels, hierarchy, and relationships understandable.
Portfolio evidenceFreddy reorganised capability around customer intent instead of internal product structure.Flows, states, and transitions
Model the whole task—including entry, progress, empty states, interruptions, completion, and return.
Portfolio evidenceThe Freddy flow builder made branching, configuration, preview, and publication visible together.Feedback and system status
Make cause, effect, progress, and consequences visible at the moment they matter.
Portfolio evidenceQapita’s vesting preview connected configuration choices to future allocation.Error prevention and recovery
Reduce high-cost mistakes, preserve context, and give people a clear route back.
Portfolio evidenceAriba’s master-detail model supported consequential exception resolution without losing the invoice.Prototyping and evaluation
Use representations at the right fidelity to learn about behaviour before committing implementation.
Portfolio evidenceAthenahealth used feature exploration and block diagrams to test scope early.Inclusive interaction
Design language, controls, focus, timing, and feedback for varied abilities and contexts.
Portfolio evidenceAccessibility is treated as a quality direction across the organisational practice.Reference material
