Towards ubiquitous requirements engineering through recommendations based on context histories

The growing technological advance is causing constant business changes. The continual uncertainties in project management make requirements engineering essential to ensure the success of projects. The usual exponential increase of stakeholders throughout the project suggests the application of intelligent tools to assist requirements engineers. Therefore, this article proposes Nhatos, a computational model for ubiquitous requirements management that analyses context histories of projects to recommend reusable requirements. The scientific contribution of this study is the use of the similarity analysis of projects through their context histories to generate the requirement recommendations. The implementation of a prototype allowed to evaluate the proposal through a case study based on real scenarios from the industry. One hundred fifty-three software projects from a large bank institution generated context histories used in the recommendations. The experiment demonstrated that the model achieved more than 70% stakeholder acceptance of the recommendations.

A Value Focused Thinking Approach to Decommissioning Decision Making

Values are what stakeholders regard to be important to decisions (Kruglanski & Higgins 2007). How stakeholder prioritize, rank, balance, and trade-off values can have significant influence on their reasoning and evaluation of decommissioning outcomes and decisions. Stakeholder values can vary depending on various factors including religious beliefs, personal interests, and past experiences (Lechner et al., 2017). Value-focused thinking is a decision science theory developed by Keeney (1992) which builds upon the concept of varying stakeholder values. Keeney (1992) argues that the best decision is one that best reflects the actual values of stakeholders. which suggests that the acceptability of decommissioning decisions (full removal, partial removal, leave in-situ, rigs-to-reefs, etc.) by stakeholders will vary depending on the values of stakeholder in that particular context. This paper explores the idea of value-focused thinking and derive implications for decommissioning decision-making. Overall, the research finding suggests that rather than basing a decommissioning decision solely on scientific evidence, there is also a need for the decommissioning decisions to be able to reflect the actual values of stakeholders in that particular context. The criteria and weightage of the adopted multi-criteria decision analysis tool, for example, should accurately represent the actual values of stakeholders, so as to enable the tool to produce outcomes and decisions that has a higher probability of stakeholder acceptance.

STAKEHOLDER ENGAGEMENT AND EFFECTIVE STANDARD-SETTING

Successful standard-setting outcomes require some level of acceptance by diverse stakeholder groups. This study examines the evolution of FASB due process institutions since Enron, which have the potential to engender stakeholder acceptance. The prior literature on accounting standard-setting outcomes often focuses on the effects of individuals, organizations, or established due process institutions. Our study highlights the critical role played by recent due process institutions such as enhanced advisory groups, transition resource groups, field tests, and post-implementation reviews in contemporary standard-setting activity. Advisory groups, in particular, shift the balance of power within standard-setting to give a stronger voice to specific stakeholders (e.g., investors, not-for-profits, and private companies) and sometimes provide a recruiting network for future FASB members. We synthesize the growing importance these due process institutions have for effective standard-setting outcomes with the academic literature to identify areas for future research.

Between Food and Respect for Nature: On the Moral Ambiguity of Norwegian Stakeholder Opinions on Fish and Their Welfare in Technological Innovations in Fisheries

Innovation in fisheries is a global development that focuses on a broad range of aims. One example is a project that aims to develop technology for key phases of the demersal fishery operation to improve product quality and safeguard fish welfare. As this step to include welfare is novel, it raises questions associated with stakeholder acceptance in a wider aim for responsible innovation. How do stakeholders (a) value fish and their welfare and (b) consider the relation between welfare and other relevant values? To address these questions, an approach combining desk research with an empirical study was used. The desk study analysed the ethical and biological arguments for whether fish welfare should be accounted for in this context. The empirical study explored how fish and their welfare are perceived by Norwegian professionals in this industry, by conducting semi-structured interviews and subsequently analysing the results based on a labelling method we developed. The desk study showed a consensus that welfare should be considered in its own right, while at face value the interviews presented a rather instrumental view on this theme. However, analysis of the interview results leads to a more nuanced picture, where fish and their welfare are viewed from the perspective of respect for nature. Despite the apparent divergence between stakeholder opinions and the literature on the importance of welfare, we present three steps that enables professionals to be responsive to both the (moral) views of stakeholders and accounting for welfare in the innovation process fisheries.

Circular Economy Models in Agro-Food Systems: A Review

Around the world, interest is growing in the circular economy in response to the current unsustainable model of production and consumption based on increased use and depletion of resources. This paper provides a review of the academic literature on the circular economy in agri-food systems, with the aims of understanding its main characteristics and perspectives, and summarizing and discussing the literature in this field. This review provides a deeper understanding of the opportunities provided by the circular economy as a solution to the current need to reduce the environmental impacts of business-as-usual economic systems and the state of the art of the circular economy in the academic debate. The results are discussed based on the chosen topic-core investigated in this review: business model and organization management, food loss and waste along the supply chain, analytical tools for the circular economy, stakeholder acceptance of the circular economy, and mitigation strategies and political approach. The findings show the need for the implementation of cleaner production models and consequent increases in stakeholder responsibilities and awareness, from both producers and consumers, as well as the need for the implementation of suitable policies and tools.

The cost of improving care: a multisite economic analysis of hospital resource use for implementing recommended postpartum contraception programmes

BackgroundThe costs of quality improvement efforts in real-world settings are often unquantified. Better understanding could guide appropriate resource utilisation and drive efficiency. Immediate postpartum contraceptive care (ie, placement of an intrauterine device or contraceptive implant during hospitalisation for childbirth) represents an excellent case study for examining costs, because recommended services are largely unavailable and adoption requires significant effort. We therefore evaluated the cost of implementing immediate postpartum contraceptive services at four academic centres and one private hospital in USA.MethodsIn this mixed-methods cost analysis, implementation activities were retrospectively identified using standardised data collection. Activities were categorised as preimplementation activities (infrastructure building, tool creation and stakeholder engagement) or execution activities (workforce training and process refinement). Costs were assigned based on national median salaries for the roles of individuals involved. Cross-case comparison and rapid qualitative analysis guided by the Consolidated Framework for Implementation Research were used to identify factors driving cost variation observed across sites.ResultsOn average, implementation activities required 204 hours (range 119–368), with this time costing $14 433.94 (range $9955.61–$23 690.49), and involving 9 (range 7–11) key team members per site. Preimplementation activities required more resources than execution activities (preimplementation: average 173 hours, $11 573.25; execution: average 31 hours, $2860.67). Sites that used lower-cost employees (eg, shifting tasks from a physician to a project manager) observed lower costs per hour for implementation activities. Implementation activities and costs were associated with local contextual factors, including stakeholder acceptance, integration of employees and infrastructure readiness for the change effort.ConclusionsOur findings provide the first estimates of health system costs for adopting recommended contraceptive care in maternity units in USA. More broadly, our findings suggest that the budget impact of improvement efforts may vary widely depending on local context.

Investigation of Strategic Deployment Opportunities for Unmanned Aerial Systems (UAS) at INDOT

Unmanned aerial systems (UAS) are increasingly used for a variety of applications related to INDOT’s mission including bridge inspection, traffic management, incident response, construction and roadway mapping. UAS have the potential to reduce costs and increase capabilities. Other state DOTs and transportation agencies have deployed UAS for an increasing number of applications due to technology advances that provide increased capabilities and lower costs, resulting from regulatory changes that simplified operations for small UAS under 55 pounds (aka, sUAS). This document provides an overview of UAS applications that may be appropriate for INDOT, as well as a description of the regulations that affect UAS operation as described in 14 CFR Part 107. The potential applications were prioritized using Quality Function Deployment (QFD), a methodology used in the aerospace industry that clearly communicates qualitative and ambiguous information with a transparent framework for decision making. The factors considered included technical feasibility, ease of adoption and stakeholder acceptance, activities underway at INDOT, and contribution to INDOT mission and goals. Dozens of interviews with INDOT personnel and stakeholders were held to get an accurate and varied perspective of potential for UAVs at INDOT. The initial prioritization was completed in early 2019 and identified three key areas: UAS for bridge inspection safety as a part of regular operations, UAS for construction with deliverables provided via construction contracts, and UAS for emergency management. Descriptions of current practices and opportunities for INDOT are provided for each of these applications. An estimate of the benefits and costs is identified, based on findings from other agencies as well as projections for INDOT. A benefit cost analysis for the application of UAS for bridge inspection safety suggests a benefit cost over one for the analysis period.
