    Opis:
    A proper estimation of time in user stories is a crucial task for both the IT team as well as for the customer, especially in agile projects. Although agile practices offer a lot of flexibility and promote a culture of continuous change, there are always clearly de need timeboxed periods where an IT company has to commit to delivering working soft-ware. Estimating time of user story implementation provides clarity and the opportunity to control the project by the management, yet at the same time, it can increase pressure on software developers. Thus, incorrectly estimated user stories may lead to quality problems including system malfunction, technical debt, and general user experience issues. The paper describes user story characteristics, reasons of user story estimation inaccuracy as well as a model of their potential impact on post-release defects in large IT software ventures, all derived from the conducted interview with practitioners in Capgemini software development company.

    Opis:
    Context: The Technical Debt metaphor has grown in popularity. More software is being created and has to be maintained. Agile methodologies, in particular Scrum, are widely used by development teams around the world. Estimation is an often practised step in sprint planning. The subject matter of this paper is the impact technical debt has on estimations. Objective: The goal of this research is to identify estimation problems and their solutions due to previously introduced technical debt in software projects. Method: The Systematic mapping study (SMS) method was applied in the research. Papers were selected from the popular digital databases (IEEE, ACM, Scopus, etc.) using defined search criteria. Afterwards, a snowballing procedure was performed and the final publication set was filtered using inclusion/exclusion criteria. Results: 42 studies were selected and evaluated. Five categories of problems and seven proposed solutions to the problems have been extracted from the papers. Problems include items related to business perspective (delivery pressure or lack of technical debt understanding by business decision-makers) and technical perspective (difficulties in forecasting architectural technical debt impact or limits of source code analysis). Solutions were categorized in: more sophisticated decision-making tools for business managers, better tools for estimation support and technical debt management tools on an architectural-level, portfolio approach to technical debt, code audit and technical debt reduction routine conducted every sprint. Conclusion: The results of this mapping study can help taking the appropriate approach in technical debt mitigation in organizations. However, the outcome of the conducted research shows that the problem of measuring technical debt impact on estimations has not yet been solved. We propose several directions for further investigation. In particular, we would focus on more sophisticated decision-making tools.

    Opis:
    Sharing research data from public funding is an important topic, especially now, during times of global emergencies like the COVID-19 pandemic, when we need policies that enable rapid sharing of research data. Our aim is to discuss and review the revised Draft of the OECD Recommendation Concerning Access to Research Data from Public Funding. The Recommendation is based on ethical scientific practice, but in order to be able to apply it in real settings, we suggest several enhancements to make it more actionable. In particular, constant maintenance of provided software stipulated by the Recommendation is virtually impossible even for commercial software. Other major concerns are insufficient clarity regarding how to finance data repositories in joint private-public investments, inconsistencies between data security and user-friendliness of access, little focus on the reproducibility of submitted data, risks related to the mining of large data sets, and sensitive (particularly personal) data protection. In addition, we identify several risks and threats that need to be considered when designing and developing data platforms to implement the Recommendation (e.g., not only the descriptions of the data formats but also the data collection methods should be available). Furthermore, the non-even level of readiness of some countries for the practical implementation of the proposed Recommendation poses a risk of its delayed or incomplete implementation.
