User-Centered Design in Agile software development for in-house enterprise tools

Farebo, Samuel January 2015 (has links)
The Agile software development model is driven by "learning by doing" and rejects Big Design Up Front (BDUF) for that reason. User-Centered Design (UCD) on the other hand requires a more holistic view to be able to create a usable user interface and in the end create a good user experience. Finding a balance between the incremental development and the need for a more comprehensive view of the user interface is therefore the key to usability in Agile software development. The objective of this master thesis was to construct a framework on how to combine UCD and Agile development in general, and specifically for the web based tool, called Alo, at the IS/IT department of Com Hem AB, Sweden. The results of this thesis was that the process of integrating User-Centered Design in Agile software development first of all needs a familiar starting point for both usability experts and developers. This can be achieved with what Desirée Sy describes as “Cycle Zero”, to let usability experts perform initial research ahead of implementation. Designing one sprint ahead should later converge to a more synchronized process where requirements and sketches of the interface are put together, with the help of developers, just in time for the implementation. This does not only prevents waste in the form of documentation and miscommunication associated with hand-offs, but also makes the implementation more purposeful and fun for developers.Secondly, build prototypes early in the process to create a holistic vision of the finished product and to test concepts in usability tests early. Thirdly, create shared understanding (within the development team as well as with outside stakeholders) of user needs by involving the entire team in usability testing. Critical to the success of all the above is that all outside stakeholders understands the Agile process and respects that the team is a self-organizing unit that solves problems within a set of given boundaries, rather than a code factory that feeds on specification documents.

Human Factors Design and Evaluation of Augmented Reality for Mass Casualty Incident Triage

Nelson, Cassidy Rae 09 September 2024 (has links)
Augmented reality (AR) is an emerging technology with immense potential for enhancing human-to-human interaction tasks, particularly in high-risk environments such as mass casualty incident (MCI) tri-age. However, developing practical and effective AR tools for this purpose necessitates a meticulous user-centered design (UCD) process, thoughtfully crafted and validated through iterative testing with first responders in increasingly contextually relevant simulations. In academic circles, the perceived complexity and time requirements of such a process might discourage its adoption within the constraints of traditional publishing cycles. This is likely due, in part, to a lack of representative applied UCD examples. This work addresses this challenge by presenting a scholarly UCD framework tailored specifically for MCI triage, which progresses seamlessly from controlled, context-free laboratory settings to virtual patient simulations and finally to realistic patient (actor) scenarios. Moreover, MCIs and triage are under-served areas, likely due to their high intensity and risk. This means developers need to 'get it right' as quickly as possible. UCD and evaluation alone are not an efficient means to developing these complex and dangerous work domains. Thus, this research also delves into a cognitive work analysis, offering a comprehensive breakdown of the MCI triage domain and how those findings inform future AR sup-ports. This analysis serves to fortify the foundation for future UCD endeavors in this critical space. Finally, it is imperative to recognize that MCI triage fundamentally involves human-to-human interaction supported by AR technology. Therefore, UCD efforts must encompass a diverse array of study stimuli and participants to ensure that the technology functions as intended across all demographic groups. It is established that racial bias exists in emergency room triage, creating worse outcomes for patients of color. Consequently, this study also investigates the potential impact of racial biases on MCI triage efficacy. This entire body of work has implications for UCD evaluation methodology, the development of future AR support tools, and the potential to catch racially biased negative performance before responders ever hit the field. / Doctor of Philosophy / Augmented reality (AR) is uniquely situated to make work within high-risk work environments, like mass casualty incident (MCI) response, safer and more effective. This is because AR augments the user's reali-ty with context-relevant information, like by providing a temperature gauge for firefighters that is always in their visual field. Development of such AR tools for a sensitive arena like MCIs requires several rigor-ous steps before those tools can be deployed in the field. It is crucial to engage in a user-centered design (UCD) process in partnership with actual emergency responders so they can help us understand what help they need. We outline that UCD process in Chapter 2. Once we understand what responders say they need help with, we then need to evaluate those pinch points in the broader context of their work. This means that we evaluate how their job process creates the situation where responders need the kind of help they are asking for. Understanding this helps us create solutions that address the responder's needs while we minimize any new problems created with implementing a new tool into the job. What we learned from examining the work domain is described in Chapter 3. Once we have this firm foundational understanding of responder needs and work and we have designed an AR support tool, we need to evaluate that tool for effectiveness. It is too dangerous to put the AR tool straight into the field, so Chapter 4 explores how we can create simulations of an MCI scenario to study our AR support tool. Finally, after evaluating our AR tool within the scenarios and the scenarios themselves, we evaluate (in Chapter 5) other facets of the job that may be impacting MCI response. In our case, we explore how racial bias may be impacting patient care. It is important to study bias as it has implications for future MCI training and AR tool development. Perhaps future work can explore an AR tool that offsets bias-based performance, or a training that helps catch bias before responders ever get to the real field.

A Phenomenological Approach to User-Centered Design: Conceptualizing the Technology Design Space to Assist Military Veterans with Community Reintegration

Haskins Lisle, Alice Catherine 17 October 2017 (has links)
The current best practices of user-centered design (UCD) may not be optimal with respect to eliciting information from representative users from special populations. This research extended elicitation approaches traditional focus on user needs and context to include criteria describing obstacles users encounter. Military veterans were selected for this research effort as representative users for a use case in technology design that addresses the difficulties associated with community reintegration. This work provides several contributions to the UCD field. First, different elicitation methods were compared by the depth and breadth of design space criteria elicited. Guidelines were generated for designer use of phenomenology in practice. Obstacles were added as an important facet of design, with corresponding grammar rules for construction. Finally, an algorithm was applied as a method for generating personas. Additionally, this dissertation contributes to the field of veteran research. Some example contributions include a set of design space criteria for designers to consider when designing for veterans, and two veteran personas grounded in data procured from the analysis. This research effort was conducted in three phases: elicitation, first-cycle analysis, and second-cycle analysis. The elicitation process engaged 40 military veterans to complete an interview session and a design session. These sessions explored the lived experience of veterans as they reintegrate into communities, and gathered their ideas for technology to assist with veteran reintegration. The researchers who conducted first-cycle coding focused on categorizing the most important participant statements (meaning units) using a codebook. This analysis resulted in over 3,000 meaning units. Additionally, the meaning unit corpus was subjected to systematic second-cycle analyses, using standardized linguistic structures to generate design space criteria. In total, over 6,000 design space criteria were discovered, and these criteria were synthesized to create personas using a situated data mining (SDM) algorithm. Results suggest that the interview session was crucial to elicit higher quantity and broader coverage of design space criteria. It is recommended that designers conduct and analyze interviews that focus on understanding the lived experience of users (not on their technology ideas) as part of a UCD approach. / Ph.

Användarcentrerat förbättringsarbete av CRM gränssnitt

Lindqvist, Lovisa, Lindström, William January 2024 (has links)
This study presents a case study that addresses a Customer Relationship Management (CRM) system as a key component in managing customer relations for companies. Due to these systems being very complex and needing a complete understanding of the user requirements to support their actions, this user experience can potentially be hindered. This study aims to highlight these challenges by identifying key usability challenges faced by users and suggesting targeted design improvements from a developer perspective.   This qualitative study explored usability challenges within an existing CRM system through a user-centered approach, gathering data from the users of the CRM-system. Empirical data was collected using interviews in a semi-structured form to delve into the user experience and what issues the users was facing. This methodology has facilitated a great understanding of areas that would need further development of the CRM-system. Applying Nielsen’s usability heuristics as an analytical framework, multiple critical enhancements were identified. These recommendations for enhancements are aimed with the goal of simplifying the user interface and the work conducted in it. The active involvement of the users in this study addressed multiple critical factors of improvements in the CRM-system, with the likes of the importance of integrating direct communication tools within the CRM-system to facilitate direct customer interaction. Additionally, there emerged a need for further development of the system’s performance and responsiveness, as well as enhancing its personal flexibility to adapt the CRM-system to each user's individual work process. This study contributes to the ongoing discourse on enhancing CRM-system effectiveness and user satisfaction through strategic design enhancements.

Användarinvolvering -        en viktig faktor vid implementering av affärssystem i små företag

Rexhaj, Rajmonda, Dahlin, Malin January 2011 (has links)
Idag är det många företag som misslyckas med sina implementeringsprojekt av affärssystem och många forskare anser att det beror på bristande användarinvolvering. Implementeringsprojekt av affärssystem blir allt vanligare i små företag, men effekten blir dock stor om ett mindre företag misslyckas med sitt projekt. Små företags misslyckanden är oftast relaterade till finansiella och humanitära kritiska framgångsfaktorer.   Ett affärssystem kan ge ett företag en rad olika fördelar och möjligheter. Men för att ett företag ska uppnå dem krävs ett lyckat implementeringsprojekt samt att användarna omgående efter driftstart kan använda affärssystemet. Därför måste företagsledare under projektet se till en rad olika kritiska framgångsfaktorer som är relaterade till användarinvolvering. För att kunna hantera användarrelaterade kritiska framgångsfaktorer och de problem som de kan orsaka finns det angreppssätt till stöd. Ett angreppssätt vars syfte är att stödja användarinvolvering och hantera användarrelaterade problem är Participatory design (PD) och dess metod User centered design (UCD). PD och UCD bygger på att involvera användarna tidigt och ständigt under ett implementeringsprojekt och det i form av bland annat testning och utbildning. Användarinvolvering är därmed en viktig faktor vid implementeringsprojekt av affärssystem.   Syftet med studien är att göra företagsledare medvetna om vilka användarrelaterade kritiska framgångsfaktorer och problem som kan påverka ett implementeringsprojekt och dess utfall. Vi anger ett antal åtgärder, baserade på användarinvolvering, som ska stödja företagsledare att bättre och effektivare kunna förutse och hantera användarrelaterade problem vid implementeringsprojekt.   Vi har med stöd av en kvalitativ undersökning och en empirisk studie påvisat sambandet mellan områdena affärssystem, affärssystemets implementeringsprocess, användarrelaterade kritiska framgångsfaktorer och användarinvolvering. Vi har konstruerat en egen modell och tabell, 4-A Modellen och 4-A Tabellen, som illustrerar hur de olika områdena relaterar och stödjer varandra under ett affärssystems implementeringsprojekt. Vårt bidrag är ett dokument vars syfte är att stödja företagsledare vid planering innan och under ett implementeringsprojekt, främst när det gäller projektets användarinvolvering. Dokumentet ska göra företagsledare medvetna om vad bristande användarinvolvering kan leda till, samt när och hur användare bör involveras under ett implementeringsprojekt. / Today many businesses fail in their enterprise recourse planning (ERP) implementation projects and many scientists believe it is due to lack of user involvement. ERP implementation projects are becoming more common in small businesses, but the effect will be large if a small business fails in their ERP implementation projects. Small businesses failures are usually related to financial and humanitarian critical success factors.   An ERP system can give a business a number of advantages and opportunities. But it requires a successful implementation project to achieve them and also that user immediately after start-up can use the ERP. Therefore, the manager during the implementation project needs to ensure a range of critical success factors that are related to user involvement. There are a number of approaches to manage user-related critical success factors and the problems they cause. An approach which aims to support user involvement and manage user-related problems is Participatory Design (PD) and its method User centered design (UCD). PD and UCD are based on involving the users early and continuously during the ERP implementation process and that in the form of testing and training. User Involvement is therefore an important factor in ERP implementation projects.   The aim of the study is to make managers more aware of the user-related critical success factors and issues that can affect an ERP implementation projects outcome. We foresee a number of measures, based on user involvement, which will support managers to better and more efficient anticipate and manage user-related problems in ERP implementation projects.   Supported by a qualitative and an empirical study, we have demonstrated the relationship between the areas ERP, ERP implementation process, user-related critical success factors and user involvement. We have constructed our own model and table, the 4-A Model and the 4-A Table, that illustrates how the different areas influences and support each other in an ERP implementation project. Our contribution is a document whose purpose is to support managers when planning a project’s user involvement, before and during an ERP implementation project. The document will make manager aware of what the lack of user involvement can lead to, but also when and how the users should involve in an ERP implementation project.

Utveckling av GUI utifrån en given affärsprocess

Stoor, John-Bernhard January 2016 (has links)
Preem verkar inom drivmedelsbranschen som styrs av en mycket hög omsättning med förhållandevis små marginaler. Det är därför viktig med en väl fungerande lagerkontroll. Det man idag är ute efter är en ökad precision i lageruppföljningen och därmed behövs ett nytt systemstöd till detta. Jag fick i min roll hos Preem uppgiften att titta närmre på GUI och processerna bakom. Det resulterade i denna rapport med ett framtaget förslag på användargränssnittet till det nya systemet och dess affärsprocesser som är kopplat till detta. Arbetet fokuserar på hur de två framställs i förhållande till varandra och vilka metoder som används för att konstruera dessa. Arbetet inkluderar illustrationer av as-is och to-be processmodeller enligt BPMN specifikation, wireframes och en sitemap. Denna rapport visar ett förslag på ett sammanfört system och ett intuitivare GUI med nya processer bakom, för just Preem, och hur balansgången går mellan att skapa affärsprocesser och ett grafiskt användargränssnitt ur varandra, beroende av vilka som är involverade i projektet. / Preem is a Swedish company that operates in the oil industry, which is controlled by very high sales and with relatively small margins. It’s therefore essential with a well working stock control. Today they are looking for a better way of monitoring the stock with a higher precision and therefore they need a new system for that. My role at Preem was to take a closer look at the GUI and the processes behind that. It resulted in this thesis that includes the user interface for the new system and the business processes that are linked to this. The work will focus on how these two methods are produced in relation to each other, and the methods that are used to construct them. The thesis includes illustrations of as-is and to-be process models of the BPMN specification, wireframes and a sitemap. This report shows a proposal of an integrating system and an intuitive GUI with new processes, at Preem, and how the balance is between creating business processes and a graphical user interface out of each other, depending on the people who are involved in the project.

Development of an Indoor Cultivation Product for Restaurant Environments : Developing a Product Specification and Creating a Product Concept using User-Centered Design

Holmqvist, Sofia, Svensson, Moa January 2019 (has links)
In today’s society there is a growing awareness of where food is produced and there is a trend to use locally grown produce in restaurants. One way for restaurants to differentiate themselves is to grow the produce inside the restaurant. This thesis has the aim on identifying the problems and user needs for an indoor cultivation solution and developing a new indoor cultivation product that solves the identified problems and meet the user needs. To achieve this aim, a usercentered design approach was utilised and the following three research questions were answered: How can the needs of the user be translated into a product specification for indoor cultivation in restaurants? What are the functionality, usability, and construction requirements for an indoor cultivation product in a restaurant? What product concept can be designed to grow classic herbs in restaurants based on the needs of the user? To identify the needs interviews were performed with the users. The needs were then translated, together with the company’s needs, into a product specification. This was done in two steps, identifying the metrics and setting values. Some of the most important requirements are that a hydroponic system is used, that the product is easy to clean and is moveable. The product development process was iterative and included different ideation, development and evaluation methods. The users were involved in some of the evaluation methods to give input on the final design. Their opinion, together with evaluations based on the product specification, were used when choosing the final concept Lärad. Lärad uses a circulating hydroponic system and have three separate growing containers each containing 16 plants. The growing containers can be pulled out to enable easy access of the plants. Both the water system and the LED grow lights, that replaces natural sunlight, are controlled automatically to minimise the users’ involvement. To test the concept, to see how well the product specification is fulfilled, both a CAD model and a functional prototype were created. The results from the tests were, even at the concept stage, that 97% of all the tested requirements were fulfilled which shows that the concept is suitable for indoor cultivation in a restaurant environment. Some further work that includes refining the design and optimising for production will be needed to launch the product.

Digital Design för att främja kommunikation i astmavård : Hur digitala tjänster genom individanpassad information kan komplettera och främja vårdmötet / Digital Design as a means to promote communication in Asthma Care : How digital services through individualized information can complement and promote the healthcare meeting

Thorsén, Andreas January 2019 (has links)
I Sverige uppskattas 800 000 personer leva med astma. I landet pågår ett digitaliseringsarbete för att via e-tjänster göra vården mer tillgänglig för patienter. E-tjänster avsedda för astmavård har uppvisat svårigheter att främja kommunikation mellan patient och vårdgivare. E-tjänster har inte ansetts kunna ersätta den personliga kontakt som ett möte mellan patient och vårdpersonal erbjuder. Bristande kontakt med vården kan leda till att gradvis försämring av astmasymtom inte upptäcks. Det kan också leda till en avsaknad av upplevt socialt stöd hos patienten, vilket kan leda till sämre mental hälsa. För att undersöka hur e-tjänster för astmavård kan designas för att, genom individanpassad information, främja och upprätthålla kommunikationen mellan patient och vårdgivare, till stöd för god vård och patienthälsa, har en studie uppdelad i tre steg genomförts. Denna studie inleddes med en litteratursökning, följdes av en intervjustudie med öppna intervjuer och avslutades i en konceptdriven designprocess. Intervjuerna analyserades mot tidigare teorier och användes tillsammans med dessa som grund för att skapa ett designkoncept tänkt att främja och upprätthålla kommunikation mellan patient och vårdgivare i astmavården. Designkonceptet, “Astmaportalen”, togs iterativt fram genom en konceptdriven designmetod vilken involverade astmavårdpersonal, astmapatienter samt informatikstuderande. Konceptet manifesterades i form av en digital prototyp. Utvärderingar med astmavårdpersonal, astmapatienter och informatikstuderande visade att designkonceptet skulle kunna utgöra ett användbart bidrag till en symbios av vårdmöten på plats och digitala lösningar. / In Sweden, 800,000 persons are estimated to live with asthma. There is an ongoing digitization work in the country, to make healthcare more accessible to patients through the use of e-services. E-services intended for asthma care have shown difficulties in promoting communication between patients and the caregiver. E-services have not been considered able to replace the personal contact that a healthcare meeting between the patient and the caregiver offers. Lack of contact with the healthcare can lead to gradual deterioration of asthma symptoms not being detected. It can also lead to a patient-perceived lack of social support, which can lead to poorer mental health for the patient. To explore how e-services for asthma care can be designed in order to, through individualized information, promote and maintain communication between patient and the healthcare provider, in support of good care and patient health, a study divided into three steps has been carried out. The study began with a literature search, was followed by an interview study with open interviews and ended in a concept-driven design process. The interviews were analyzed against previous theories and used together with these as the basis for creating a design concept intended to promote and maintain communication between the patient and the caregiver in asthma care. The design concept, "Astmaportalen” (“The Asthma Portal"), was iteratively created through a concept-driven design method which involved asthma care personnel, asthma patients and informatics students. The concept was manifested in the form of a digital prototype. Evaluations with asthma care personnel and asthma patients demonstrated that the design concept could make a useful contribution to a symbiosis of healthcare meetings on site and digital solutions.
