Part1: Purpose of a Wants and Needs Analysis
Wantsand needs analysis helps in the understanding of a design that isuser-centred. Moreover, the analysis contributes to brainstormingand gathering information concerning multiple users of a product atthe same time. It is also used to identify the user objectives,features, and system requirements. Furthermore, the wants and needsanalysis exercise helps to focus and prioritize the featuresrequired, features to be removed, and possibly those features to becharged for (Johnson, 2012).
Part2: Forms of Wants and Needs Questions
Thecategorical questions include yes/no questions, multiple choicequestions, and checkbox questions. When analyzing the questions inthis category, the analysis will include counts and percentages.After analysis, the data can be presented using bar graphs andpie-charts (Johnson, 2012).
Theresponses to ordinal questions are usually given following orders.The ordinal data is collected using ranking questions, multiplechoice questions and use of drop down questions (Johnson, 2012).
Intervalquestions allow a researcher to conduct an analysis. Important tonote is that advanced analysis such as testing correlations,regression models, and averages are best found from intervalquestions (Johnson, 2012).
Howto prepare for and conduct a card sort
Iwill make a list of content topics limiting myself to 50-60 topics orless. After I have come up with topics, I will decide whether to havea physical card sorting or use online software to sort them. Finally,I will set up the session depending on the cards I have, space,facilitator and the available incentives (Johnson, 2012).
Iwill show my participants a set of cards, and then explain to themwhat I am looking for. I will instruct my members to talk loudlywhile working so that I get insights and their rationale. In the end,I will explain how to combine groups for participants having manygroups as they name each category. After that, I will give incentivesto participants (Johnson, 2012).
Howto prepare for and conduct Group Task Analysis (GTA)
Iwill come up with a group task to be analyzed. I will research forhotels for that purpose, based on price. I will then consider thequality and prices of the hotels relative to other venues in thearea. After meeting the desired criteria, I will then book the venue.After that, I will inform my participants about the study then invitethe moderator and videographer. After the moderation by themoderator, I will finally give debrief (Johnson, 2012).
Challengeswhen conducting a GTA
Someproblems may occur when performing a GTA in that some participantsmight not contribute. Additionally, a misunderstanding may occuramong the participants. Also, tasks may delay due to over dependenceon few members. Lastly, keeping the group on track may be hard due toideological differences (Johnson, 2012).
Purposeof a focus group
Focusgroups help in involving stakeholders to give their insights onproducts supplied to them. They also offer room for interactionbetween users of particular products, non-users, and the producers(Johnson, 2012).
Differencebetween qualitative and quantitative questions
Qualitativequestions are exploratory and are used to find an understanding ofopinions, motivations, and underlying reasons from a respondentwhereas, the quantitative questions are close-ended providing alimited source of responses to participants (Johnson, 2012).
Keycriteria from a usability perspective when prioritizingrecommendations
Firstly,one has to come up with the consumer and purchaser priority measurecatering for customer situations. Secondly, the performance has to bemeasured by direct feedback from the users to build a strategy ofservice improvement.Thirdly, include all clients in the measure and document it. Next,come up with recommendations and follow them while measuring providerperformance at all levels. Finally, collect the performancemeasurement data (Johnson,2012).
Whento conduct individual interviews vs. surveys
Individualinterviews are conducted at the peak of the development cycle togather data from the participants. Surveys, on the other hand, areused to uncover the responses to vital questions, which are specific(Johnson, 2012).
Howinterviews differ from focus groups?
Interviewsentail a one on one talk with clients, industry experts, andprospects. Moreover, they are suitable for topics that are sensitivein nature as compared to focus groups, which cover general and opentopics. Also, interviews are flexible as they can be done through thephone as opposed to the focus groups (Johnson, 2012).
Whatcan be learned from a focus group?
Itcan be learned that focus groups help to understand how consumersperceive the products on the market. Moreover, marketing procedurescan be learned in focus groups, and the reasons behind customerdecisions and actions can also be examined (Johnson, 2012).
Lessonsfrom a contextual interview
Contextualinterviews assist the researcher to know and understand the issuesthat the users are going through. It also helps to understand theequipment used, setup and space used, and the time used to completetargets set (Johnson, 2012).
Howusability testing fit into user-centred design
Usabilitytesting assists in validating the user-centred design process outcomeduring product development. Usability testing guarantees that projectchoices are validated using the best practices of user-centred design(Johnson, 2012).
