    Customer Feedback and Data Collection Techniques in Software R&D: A Literature Review2015Ingår i: Software Business: 6th International Conference, ICSOB 2015, Braga, Portugal, June 10-12, 2015, Proceedings, Springer, 2015, s. 139-153Konferensbidrag (Refereegranskat)
    Abstract [en]

    In many companies, product management struggles in getting accurate customer feedback. Often, validation and confirmation of functionality with customers takes place only after the product has been deployed, and there are no mechanisms that help product managers to continuously learn from customers. Although there are techniques available for collecting customer feedback, these are typically not applied as part of a continuous feedback loop. As a result, the selection and prioritization of features becomes far from optimal, and product deviates from what the customers need. In this paper, we present a literature review of currently recognized techniques for collecting customer feedback. We develop a model in which we categorize the techniques according to their characteristics. The purpose of this literature review is to provide an overview of current software engineering research in this area and to better understand the different techniques that are used for collecting customer feedback.

    Intelligent Computing in Personal Informatics: Key Design Considerations2015Ingår i: Proceedings of the 20th ACM International Conference on Intelligent User Interfaces, ACM Associaltion of Computing Machinery , 2015, s. 263-274Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    An expanding range of apps supported by wearable and mobile devices are being used by people engaged in personal informatics in order to track and explore data about themselves and their everyday activities. While the aspect of data collection is easier than ever before through these technologies, more advanced forms of support from personal informatics systems are not presently available. This lack of next generation personal informatics systems presents research with an important role to fill, and this paper presents a two-step contribution to this effect. The first step is to present a new model of human cooperation with intelligent computing, which collates key issues from the literature. The second step is to apply this model to personal informatics, identifying twelve key considerations for integrating intelligent computing in the design of future personal informatics systems. These design considerations are also applied to an example system, which illustrates their use in eliciting new design directions.

    Expectations and Challenges from Scaling Agile in Mechatronics-Driven Companies: A Comparative Case Study2015Ingår i: Agile Processes, in Software Engineering, and Extreme Programming, Springer, 2015, s. 15-26Konferensbidrag (Refereegranskat)
    Abstract [en]

    Agile software development is increasingly adopted by companies evolving and maintaining software products to support better planning and tracking the realization of user stories and features. While convincing success stories help to further spread the adoption of Agile, mechatronics-driven companies need guidance to implement Agile for non-software teams. In this comparative case study of three companies from the Nordic region, we systematically investigate expectations and challenges from scaling Agile in organizations dealing with mechatronics development by conducting on-site workshops and surveys. Our findings show that all companies have already successfully implemented Agile in their software teams. The expected main benefit of successfully scaling agile development is a faster time-to-market product development; however, the two main challenges are: (a) An inflexible test environment that inhibits fast feedback to changed or added features, and (b) the existing organizational structure including the company’s mind-set that needs to be opened-up for agile principles.

    Analyzing the Design Space of Personal Informatics: A State-of-practice Based Classification of Existing Tools2015Ingår i: Universal Access in Human-Computer Interaction: Access to Today's Technologies: 9th International Conference, UAHCI 2015, Held as Part of HCI International 2015, Los Angeles, CA, USA, August 2-7, 2015, Proceedings, Part I, Springer, 2015, s. 85-97Konferensbidrag (Refereegranskat)
    Abstract [en]

    We are presently seeing a rapid increase of tools for tracking and analyzing activities, from lifelogging in general to specific activities such as exercise tracking. Guided by the perspectives of collection, procedural, and analysis support, this paper presents the results from a review of 71 existing tools, striving to capture the design choices within personal informatics that such tools are using. The classification system this creates is a contribution in three ways: as a standalone state-of-practice representation, for assessing individual tools and potential future design directions for them, and as a guide for new development of personal informatics tools

    Beyond a Utility View of Personal Informatics: A Postphenomenological Framework2015Ingår i: UbiComp/ISWC'15 Adjunct: Adjunct Proceedings of the 2015 ACM International Joint Conference on Pervasive and Ubiquitous Computing and Proceedings of the 2015 ACM International Symposium on Wearable Computers, ACM Digital Library, 2015, s. 1087-1092Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Quantified self apps and other personal informatics designs have rapidly grown in popularity through the advent of convenient Internet of Things related wearables and improved sensor technology. The rapid growth has, however, left its mark on how we study this area as the utility that could be provided has become the centerpiece of attention. This appears somewhat contradictory, as personal informatics technology becomes integrated in life in nuanced ways, contributing value beyond the instrumental data analysis role. In this paper, we propose relying on postphenomenology as a useful foundation for extending the study of personal informatics, and provide three concluding implications intended to guide the discussion of such an extension.

    A Novel Security-Enhanced Agile Software Development Process Applied in an Industrial Setting2015Ingår i: ARES Conference International Conference on Availability, Reliability and Security 2015, IEEE, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    A security-enhanced agile software development process, SEAP, is introduced in the development of a mobile money transfer system at Ericsson Corp. A specific characteristic of SEAP is that it includes a security group consisting of four different competences, i.e., Security manager, security architect, security master and penetration tester. Another significant feature of SEAP is an integrated risk analysis process. In analyzing risks in the development of the mobile money transfer system, a general finding was that SEAP either solves risks that were previously postponed or solves a larger proportion of the risks in a timely manner. The previous software development process, i.e., The baseline process of the comparison outlined in this paper, required 2.7 employee hours spent for every risk identified in the analysis process compared to, on the average, 1.5 hours for the SEAP. The baseline development process left 50% of the risks unattended in the software version being developed, while SEAP reduced that figure to 22%. Furthermore, SEAP increased the proportion of risks that were corrected from 12.5% to 67.1%, i.e., More than a five times increment. This is important, since an early correction may avoid severe attacks in the future. The security competence in SEAP accounts for 5% of the personnel cost in the mobile money transfer system project. As a comparison, the corresponding figure, i.e., For security, was 1% in the previous development process.

    Early Value Argumentation and Prediction: An Iterative Approach to Quantifying Feature Value2015Ingår i: Product-Focused Software Process Improvement, Springer, 2015, s. 16-23Konferensbidrag (Refereegranskat)
    Abstract [en]

    Companies are continuously improving their practices and ways of working in order to fulfill always-changing market requirements. As an example of building a better understanding of their customers, organizations are collecting user feedback and trying to direct their R&D efforts by e.g. continuing to develop features that deliver value to the customer. We (1) develop an actionable technique that practitioners in organizations can use to validate feature value early in the development cycle, (2) validate if and when the expected value reflects on the customers, (3) know when to stop developing it, and (4) identity unexpected business value early during development and redirect R&D effort to capture this value. The technique has been validated in three experiments in two cases companies. Our findings show that predicting value for features under development helps product management in large organizations to correctly re-prioritize R&D investments.

    Towards a Model of Privacy and Security for Smart Homes2015Ingår i: Proceedings: 2015 IEEE 2nd World Forum on Internet of Things (WF-loT), IEEE, 2015, s. 727-732Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    The domain of smart home environments is viewed as a key element of the future Internet, and many homes are becoming “smarter” by using Internet of Things (IoT) technology to improve home security, energy efficiency and comfort. At the same time, enforcing privacy in IoT environments has been identified as one of the main barriers for realizing the vision of the smart home. Based on the results of a risk analysis of a smart home automation system developed in collaboration with leading industrial actors, we outline the first steps towards a general model of privacy and security for smart homes. As such, it is envisioned as support for enforcing system security and enhancing user privacy, and it can thus help to further realize the potential in smart home environments.
