Enterprise architecture (EA) is a widespread approach for the development of new digital solutions in a planned and controlled way for large and complex organisations. EA is also viewed as a prerequisite for the digitalisation of the public sector. However, public sector organisations struggle to implement EA programmes, and research has demonstrated that organisational and managerial issues are critical obstacles to EA implementation. This study aims to increase our understanding of EA implementation in the public sector by investigating the central challenges for EA initiatives and to trace the progress of current EA initiatives in the Norwegian public sector. An additional goal is to disclose some ways to improve the situation. We conducted three interpretive case studies in the hospital, higher education, and labour and welfare sectors. We have identified 28 challenges to the EA initiatives. We find that organisational and technical complexities, as well as a limited understanding of EA and lack of formal EA governance mechanisms, are significant obstacles. Among others, the lack of understanding of EA and its methodology will lead to problems with anchoring the EA approach in the organisation and facilitating the necessary EA arrangements to induce the promised benefits of EA, which are necessary requirements to establish the EA initiative’s legitimacy and foster the organisation’s willingness to implement change. Our study provides four lessons learned for planning and implementing EA initiatives, as follows: #1. It is advisable to take small steps. #2. The use of external consultants should be carefully considered. #3. Formal architectural governance mechanisms are important for legitimacy and enforced use. #4. Executive commitment and understanding of EA are crucial for achieving a sustainable EA initiative. Finally, we find a common evolution of the EA initiatives through the phases of optimism, resistance, decline and finally, reconsolidation of the most persistent ones.

Background. Wearable physical activity (PA) trackers are becoming increasingly popular for intervention and assessment in health promotion research and practice. The purpose of this article is to present lessons learned from four studies that used commercial PA tracking devices for PA intervention or assessment, present issues encountered with their use, and provide guidelines for determining which tools to use. Method. Four case studies are presented that used PA tracking devices (iBitz, Zamzee, FitBit Flex and Zip, Omron Digital Pedometer, Sensewear Armband, and MisFit Flash) in the field—two used the tools for intervention and two used the tools as assessment methods. Results. The four studies presented had varying levels of success with using PA devices and experienced several issues that impacted their studies, such as companies that went out of business, missing data, and lost devices. Percentage ranges for devices that were lost were 0% to 29% and was 0% to 87% for those devices that malfunctioned or lost data. Conclusions. There is a need for low-cost, easy-to-use, accurate PA tracking devices to use as both intervention and assessment tools in health promotion research related to PA.

It’s always challenging and exciting to find topics for the readers’ advisory column, and professionals willing to write for them! I’ve been so thankful to the many professionals who have so generously given their time and shared their expertise for this column. From lessons learned, case studies and differing opinions on RA and its future, it is amazing how various and rich this area of librarianship is—and how rewarding and frustrating! In an effort to continue to provide a broad spectrum of thoughts and ideas, I asked Dr. Louise Spiteri of Dalhousie University to write for this issue. Spiteri recently completed two stages of research examining subject headings and user-generated content and how these connect with RA access points. Jen Pecoskie was Spiteri’s research partner in both studies.—Editor

This report presents lessons learned from twenty-five worldwide real-life case studies implementing the integration of daylighting and electric lighting. The case studies were monitored with respect to energy use for lighting, visual performance, non-visual performance, and users’ satisfaction. The monitoring is largely based on field measurements, but it is also complemented with simulations and calculations where needed.

Web Based Education

This article reviews the development of three Web-based education resources and the potential for each of these resources to meet the needs of users for a 'killer app'. Three case studies (the Annotated List of Education Journals, the IDEAS Portal Web Site and the Eisenhower National Clearinghouse Web Site)review the purpose, audience, content, funding, publicity and structure of the sites. Differences in staffing, funding and the centrality of these sites to the mission of their sponsoring institutions impacted the growth of these sites. Technological changes and the diffuse nature of the Internet also impacted the development of these resources.
