Requirements Engineering A Good Practice Guide

Agile Requirements Engineering: A systematic literature review

Developer, manager and user feedback is needed to optimize products. Besides the basic Software qualities � usability and user experience are important properties for improving your product.
Usability is well known and can be tested with e.g. a usability test or an expert review. In contrast user experience describes the whole impact a product has on the end-user. The timeline goes from before, while and after the use of a product. We present a tool that allows you to evaluate the user experience of a product with little effort. Furthermore the tool is available in different languages and we are using the new Spanish Version. We show how this tool can be used for a continuous user experience assessment.

Efficient measurement of the user experience of interactive products. How to use the user experience questionnaire (UEQ). Example: Spanish language version

Background: A lack of physical activity is considered to cause 6% of deaths globally. Feedback from wearables such as activity trackers has the potential to encourage daily physical activity. To date, little research is available on the natural development of adherence to activity trackers or on potential factors that predict which users manage to keep using their activity tracker during the first year (and thereby increasing the chance of healthy behavior change) and which users discontinue using their trackers after a short time. Objective: The aim of this study was to identify the determinants for sustained use in the first year after purchase. Specifically, we look at the relative importance of demographic and socioeconomic, psychological, health-related, goal-related, technological, user experience–related, and social predictors of feedback device use. Furthermore, this study tests the effect of these predictors on physical activity. Methods: A total of 711 participants from four urban areas in France received an activity tracker (Fitbit Zip) and gave permission to use their logged data. Participants filled out three Web-based questionnaires: at start, after 98 days, and after 232 days to measure the aforementioned determinants. Furthermore, for each participant, we collected activity data tracked by their Fitbit tracker for 320 days. We determined the relative importance of all included predictors by using Random Forest, a machine learning analysis technique. Results: The data showed a slow exponential decay in Fitbit use, with 73.9% (526/711) of participants still tracking after 100 days and 16.0% (114/711) of participants tracking after 320 days. On average, participants used the tracker for 129 days. Most important reasons to quit tracking were technical issues such as empty batteries and broken trackers or lost trackers (21.5% of all Q3 respondents, 130/601). Random Forest analysis of predictors revealed that the most influential determinants were age, user experience–related factors, mobile phone type, household type, perceived effect of the Fitbit tracker, and goal-related factors. We explore the role of those predictors that show meaningful differences in the number of days the tracker was worn. Conclusions: This study offers an overview of the natural development of the use of an activity tracker, as well as the relative importance of a range of determinants from literature. Decay is exponential but slower than may be expected from existing literature. Many factors have a small contribution to sustained use. The most important determinants are technical condition, age, user experience, and goal-related factors. This finding suggests that activity tracking is potentially beneficial for a broad range of target groups, but more attention should be paid to technical and user experience–related aspects of activity trackers.

Determinants for sustained use of an activity tracker: Observational study

Agile Software Development (ASD) is becoming more popular in all fields of industry. For an agile transformation, organizations need to continuously improve their established approaches to Requirements Engineering (RE) as well as their approaches to software development. This is accompanied by some challenges in terms of agile RE. The main objective of this paper is to identify the most important challenges in agile RE industry has to face today. Therefore, we conducted an iterative expert judgement process with 26 experts in the field of ASD, comprising three complementary rounds.

Key Challenges in Agile Requirements Engineering

Langwierige Diskussionen, bei denen sich die beteiligten Personen über einzelne Aspekte der Produktentwicklung nicht einigen können, sind für erfahrene UX-Professional nichts Neues. Solche Konflikte sind in der Regel kraftund zeitraubend. Sie resultieren oft aus unterschiedlichen Einschätzungen bzgl. der Wichtigkeit bestimmter Qualitätseigenschaften eines Produkts. Allerdings ist den meisten Produktteams nicht bewusst welche Aspekte wichtig sind und welche vernachlässigt werden können. Das macht die Diskussion in solchen Konfliktsituationen umso schwieriger, da die Beteiligten aus ihrer jeweiligen Perspektive Recht haben. Wir stellen einen Prozess vor, der die Reduzierung von Abstimmungskonflikten unterstützt und die Produktentwicklung dadurch beschleunigt. Als Grundlage verwenden wir 16 klar beschriebene UX-Faktoren, welche in empirischen Studien ermittelt und bzgl. ihrer Wichtigkeit für bestimmte Produktgruppen bewertet wurden.

The integration of Human-Centered Design (HCD) and Agile Software Development (ASD) promises the development of competitive products comprising a good User Experience (UX). This study has investigated the integration of HCD and Kanban with the aim to gain industrial experiences in a real world context. A case study showed that requirements flow into the development process in a structured manner by adding a design board. To this end, the transparency concerning recurring requirements increased. We contribute to the body of knowledge of software development by providing practical insights into Human-Centered Agile Development (HCAD). On one hand, it is shown that the integration of HCD and Kanban leads to a product with a good UX and makes the development process more human-centered. On the other hand, we conclude that a cross-functional collaboration speeds up product development.

Enterprise Experience into the Integration of Human-Centered Design and Kanban

To be successful, interactive products need to fulfil user expectations and create a positive user experience (UX). An established method to measure UX involves questionnaires. What we aim in this paper is to present a list of user experience and usability questionnaires and its applicability for different digital products. A total of 13 questionnaires on usability and UX were analysed for this paper, and 25 factors were extracted from those questionnaires. A study was conducted based on this collection of factors with N=61 students. The study investigated the perceived importance of usability and UX factors for seven digital products. The goal was to have a collection of usability and UX factors that could be combined for suitable products evaluation. The results of the study revealed that no questionnaire covered all the factors perceived important by the participants.
