A Survey on the Perception of Opportunities and Limitations of Generative AI in the Public Sector
Recent breakthroughs in Artificial Intelligence (AI) have increased the interest in applications of AI in general and Generative AI in particular. This interest is manifest in public debate on the promise and limitations of AI in various sectors, but also on the risks of relying upon such technology. However, little is known about the interest in and perceptions of Generative AI among Information Technology (IT) professionals likely to take responsibility for developing and implementing AI-based solutions in the public sector. We present findings from a survey we developed (with help from ChatGPT) and conducted among IT practitioners in the Norwegian public sector. Through this survey, we investigated how opportunities and limitations of the use Generative AI were perceived and understood. We found ambivalent attitudes: while the interest in Generative AI is high, the level of perceived knowledge is low; there is considerable optimism about the value of AI, but an equivalent level of concern about threats this technology represents; and although respondents suspected AI had helped generate the survey, they found the survey questions relevant and fully context-oriented. These findings provide background and context for further research into the adoption of AI and help practitioners establish a baseline for efforts to build and manage AI-based solutions in public institutions.

A Survey on the Use and Effects of Goal Hierarchies in Digitalization Efforts
Digitalization has become a primary goal for organizations. Successfully adopting the digital context both in daily operations and in business management and strategy entails great benefits at different levels (organizational, economic, social, environmental...). Thus, it is very important that practitioners have clear conceptions of the goals in this regard and that those goals are “alive” in organizations.
For this reason, in this study we present a survey that we performed among practitioners related to the management of Information Technology (IT) from both the private and public sectors in Norway. Through this survey we have tried to find out how organizations understand and translate the current context of digitalization from different goal levels. For that, we asked respondents to relate to one of three goal hierarchies: A) a classical governance approach; B) an organizational tier approach; and C) an effects-based approach.
Among the results obtained we found that the first two are the most used and the goal achievement is slightly higher for the classical governance approach than for the organizational tier approach. Likewise, we identified that while top level management has a good understanding of the goals, this understanding deteriorates as one moves down the organizational hierarchy.

An Overview of the Understanding and Use of Assessment Methods in Benefits Management

An Overview of the Understanding and Use of Assessment Methods in Benefits Management
Evidence suggests that benefits management is critical for enabling greater value and for enhancing the positive impact of programs, projects, and portfolios. However, many organizations only focus their efforts on identifying the intended benefits, without conducting a proper follow-up through ongoing assessment or evaluation to ensure benefits realization. For this reason, this study aims to obtain an overview of the actual use of the assessment methods in benefits management, through a compilation and analysis of the literature following the Systematic Mapping Study methodology. The results and findings obtained show a significant gap in the interplay between the fields of assessment methods and benefits management. Based on this, we suggest opportunities for improvement, such as developing audit guides and frameworks for enhancing the monitoring of the benefits, strengthening the focus on external benefits of organizations, and for adapting benefits assessment to the changed perceptions of intended benefits, in line with continuous improvement.

Designing and Testing a Mobile App to Fight Child, Early, and Forced Marriage in Developing Countries
Child marriage is still a severe issue in developing countries. Among the strategies that work most to fight it, is empowering girls with information combined with the education of parents and community. As smartphones are more accessible year after year in developing countries, we want to investigate how a mobile app could effectively fight child marriage and which characteristics such an app should have. The research was organized into three main phases. The first phase was focused on 4 expert semi-structured interviews to understand if an app could be a good solution to help in fighting child marriage. The second and third phases were based on a case study with young girls in the Democratic Republic of the Congo. The second phase had focus groups with 26 girls to test and improve the requi- sites of the app, and the third phase had a questionnaire that 14 girls had to fill out after trying the app. The study shows that girls in developing countries have access to smartphones, and most can use the developed app satisfactorily and that it is worth continuing to study this problem as an app could be a new instrument to use alongside traditional tools.

An Experimental Evaluation of a De-biasing Intervention for Professional Software Developers
CONTEXT: The role of expert judgement is essential in our quest to improve software project planning and execution. However, its accuracy is dependent on many factors, not least the avoidance of judgement biases, such as the anchoring bias, arising from being influenced by initial information, even when it's misleading or irrelevant. This strong effect is widely documented. OBJECTIVE: We aimed to replicate this anchoring bias using professionals and, novel in a software engineering context, explore de-biasing interventions through increasing knowledge and awareness of judgement biases. METHOD: We ran two series of experiments in company settings with a total of 410 software developers. Some developers took part in a workshop to heighten their awareness of a range of cognitive biases, including anchoring. Later, the anchoring bias was induced by presenting low or high productivity values, followed by the participants' estimates of their own project productivity. Our hypothesis was that the workshop would lead to reduced bias, i.e., work as a de-biasing intervention. RESULTS: The anchors had a large effect (robust Cohen's d=1.19) in influencing estimates. This was substantially reduced in those participants who attended the workshop (robust Cohen's d=0.72). The reduced bias related mainly to the high anchor. The de-biasing intervention also led to a threefold reduction in estimate variance. CONCLUSIONS: The impact of anchors upon judgement was substantial. Learning about judgement biases does appear capable of mitigating, although not removing, the anchoring bias. The positive effect of de-biasing through learning about biases suggests that it has value.

Do Agile Methods Work for Large Software Projects?

Do Agile Methods Work for Large Software Projects?
Some people claim that agile methods do not scale well and are mainly useful for smaller software projects. Others claim that it is particularly in the context of large, complex software projects that the use of agile methods is likely to make the difference between success and failure. To find out more about whether or not agile methods work for larger projects, we conducted a questionnaire-based survey collecting information about 122 Norwegian software projects. Project success was measured as the combined performance of the project regarding delivered client benefits, cost control, and time control. We found that that projects using agile methods performed on average much better than those using non-agile methods for medium and large software projects, but not so much for smaller projects. This result gives support for the claim that agile methods are more rather than less successful compared to traditional methods when project size increases. There may consequently be more reasons to be concerned about how non-agile, rather than how agile methods, scale.

Assisting Soccer Game Summarization via Audio Intensity Analysis of Game Highlights

Assisting Soccer Game Summarization via Audio Intensity Analysis of Game Highlights
In association football, the development of multimodal summaries is of great importance to both broadcasters and spectators since a large number of viewers choose to follow just the soccer game highlights. The fundamental drive for the development of summarization systems is the requirement to manage huge amounts of data in different formats. By highlighting the most pertinent facts and limiting or omitting unnecessary aspects, summarization helps avoid "information overload." The properties of the audio signals during a particular event can be used to calculate excitement around that event and filter events based on their importance. A root-mean-square (RMS) analysis of audio events was carried out to analyse the excitement across the events in the SoccerNet dataset. It was clearly seen that important events with excitement have a high and distinguishable RMS audio intensity. It was also observed that the generated noise of the crowd was significantly different across various events and if it happened for the home or away team. The intensity was higher for events related to the home team. Likewise, as the wavelet has the benefit of integrating a wave with a specific period, Morlet wavelet analysis was performed for various event types, and the power of the signal across various wavelet scales was analyzed. A distinct signature across various wavelet scales was observed for different events.

Benefit Considerations in Project Decisions

Benefit Considerations in Project Decisions
Software project success is often characterized in terms of time, cost and scope – despite that delivering benefit is the main purpose of a project. In this paper, we explore 1) to what degree benefit considerations influence major project decisions, 2) to what degree a specific set of benefits management challenge are handled and influence major project decisions and 3) if there is any realization (over time) that benefit considerations should receive greater attention. We investigate influence in projects with four types of problem severity: completed projects with only minor problems, completed projects with major problems, projects that were disrupted but completed, and projects that were terminated before completion. We asked 45 software professionals to what degree time, cost, scope, benefit and benefit/cost, as well as benefits management challenges, influence major roject decisions. Our findings indicate that time, cost and scope have a significantly higher degree of influence on project decisions than benefit and benefit/cost. However, practitioners think that benefit and benefit/cost should have significantly more influence on decisions than cost. The benefits management challenges are found to have less influence in the more severe projects. We argue that giving benefits considerations a stronger voice in project decisions would be in line with the desire of practitioners and the prime objective of delivering benefit to stakeholders. We conclude that it is important to understand how to handle benefits management challenges at different stages of project life and that handling such challenges should be integrated with other prime drivers of project success.

Benefits management and agile practices in software projects: how perceived benefits are impacted

Benefits management and agile practices in software projects: how perceived benefits are impacted
Considerable resources are wasted on projects that deliver few or no benefits. The main objective is to better understand the characteristics of projects that are successful in delivering good client benefits. We asked 71 Norwegian software professionals to report information about projects completed between 2016 and 2018. We found that both benefits management and agile practices have a significant relationship with perceived realisation of client benefits. This includes the benefits management practices of having a plan for benefits realisation, individuals with assigned responsibility for benefits realisation, benefits management during project execution, quantification of realised benefits, evaluation of realised benefits, re-estimation of benefits during project execution, and the agile practices of a flexible scope and frequent deliveries to production. The software projects that were successful in delivering client benefits adopted benefits management and agile practices to a larger extent than the less successful ones. Future studies are required to establish more comprehensive understanding of what distinguishes projects that deliver good client benefits from the rest, including studies of the realisation of client benefits in agile software projects.
