3 Design ProcessDifferent design process models have been proposed Who and what are these models for?SIM 14/15 - T2.1 – Iterative HCI Design Process
4 Simple interaction design model Interaction Design: Beyond Human Computer InteractionPreece, Rogers & Sharpe, 2002SIM 14/15 - T2.1 – Iterative HCI Design Process
5 Four components Identify needs/establish requirements: Core to design process – know thy user!Developing alternative designsIncludes both conceptual design and physical designBuilding interactive versions of the designsNot necessarily software: create prototypes (including simple mock-ups) that can be evaluated by usersEvaluating designsIdeally involving users at every stage, feeding evaluations back into the design processMuch easier to do if clear usability and user experience goals have been identified up frontSIM 14/15 - T2.1 – Iterative HCI Design Process
6 Interface Design and Usability Engineering Saul Greenberg (U Calgary)SIM 14/15 - T2.1 – Iterative HCI Design Process
7 Bowing to reality What makes it hard to follow the “ideal” process? DeadlinesBudgetAccess to appropriate usersInvolvement late in design cycleValuation of HCI input by other parts of the organizationWhat do you do then?SIM 14/15 - T2.1 – Iterative HCI Design Process
8 StakeholdersStakeholder = anyone who has some reason to care about the interfaceCan be lots of them!Needs may conflictUser: convenience, functionality, …Boss: price, worker efficiencyDeveloper: ease of development - deadlines, budgetManufacturer: cost of productionAdvertiser: visibility… moreSIM 14/15 - T2.1 – Iterative HCI Design Process
9 How to figure out who your stakeholders are Who will ask for it?Who will use it?Who will decide whether to use it (or if someone else will use it?)Who will pay for it?Who has to make (design / build) it ?Who has to make a profit from it?Who will otherwise make your life miserable if they don’t like it????SIM 14/15 - T2.1 – Iterative HCI Design Process

12 Important things for today Design is an iterative processEvaluation is key!There are several HCI design modelsChoose one? Adapt one?Identifying stakeholdersVital since they are the ones that careSIM 14/15 - T2.1 – Iterative HCI Design Process
