  • IntroductionUser involvement in the development processContents:AdvantagesPrinciplesUnderstanding users work: applying ethnography in designInvolving users in design: participatory design

  • AdvantagesDevelopers gain a lot for better product by understanding users betterExpectation managementMake sure that the users views and expectations are realisticSupport the users work more effectivelyHelp the users to know and understand the product at the early stagetrainingOwnership

  • Degrees of involvementFull-time or part-timeDuration of the whole project or a limited timeThrough newsletters or workshopAttending evaluations

  • PrinciplesTo design a useful and easy to use computer systemEarly focus on users and tasksEmpirical measurementIterative design

  • Early focus on users and tasksUsers tasks and goals are the driving force behind the developmentUsers behavior and context of use are studied and the system is designed to support themUsers characteristics are captured and designed for.Users are consulted throughout development from earlier phases to the latest and their input is seriously taken into accountAll design decisions are taken within the context of the users, their work, and their environment

  • Involving users in design: Participatory DesignUsers are actively involved in development. They design the product in cooperation with the designers

  • PICTIVE(Plastic Interface for Collaborative Technology Initiatives through Video Exploration)

  • PICTIVE --- continuedThe stakeholders all introduce themselvesBrief tutorials about the different domainsBrainstorming the designsA walkthrough of the design and the decision discussed

  • CARD(Collaborative analysis of Requirements and Design)Takes a more macroscopic view of the task flow, while PICTIVE concentrates on detailed aspects of the system

  • ConclusionInvolving users in the design process helps with expectation management and feelings of ownership, but how and when to involve users is a matter of disputePutting a user-centered approach into practice requires much information about the users to be gathered and interpretedEthnography is a good method for studying users in their natural surroundings

  • Conclusion -continuedRepresenting the information gleaned from an ethnographic study so that it can be used in design has been problematicThe goals of ethnography are to study the details, while the goals of system design are to produce abstractions; hence they are not immediately compatible

  • Conclusion continued 2Coherence is a method that provides focus questions to help guide the ethnographer towards issues that have proved to be important in systems developmentContextual design in a method that provides models and techniques for gathering contextual data and representing it in a form suitable for practical designPICTIVE and CARD are both participatory design techniques that empower users to take an active part in design decisions
