-Today, and for the foreseeable future, organizations will face ever-increasing levels of complexity and uncertainty. Many believe that enterprise architecture (EA) will help organizations address such difficult terrain by guiding the design of adaptive and resilient enterprises and their information systems. This paper presents the "Grand Challenges" that we believe will challenge organizations in the future and need to be addressed by enterprise architecture. As a first step in using enterprise architecture as a solution for overcoming identified challenges, the Zachman Enterprise Architecture Framework is used to guide and structure the discussion. The paper presents the "Grand Challenges" and discusses promising theories and models for addressing them. In addition, current advances in the field of enterprise architecture that have begun to address the challenges will be presented. In conclusion, final thoughts on the future of enterprise architecture as a research field and a profession are offered.

Supply chain social responsibility is increasingly a pressing concern to organizations of all sizes.Justified by its impact on the bottom line, various measures were adopted for resolution and prevention. However, despite the abundance of literature on the topic, there continues to be a lack of evidence on which of the measures are the most prolific, that is, how the concern of interest is actually handled. Such evidence would highlight missed opportunities and set the stage for future research. Toward this goal, the authors conducted a mapping study analyzing 590 articles. The findings reveal that corporate social responsibility, sustainable reporting, and social life cycle assessment are the most used methods whereas systems thinking ranks far behind. This work is original in that it is the first of its kind to reveal such findings scientifically. Practical implications of this work include reducing the supply chain's social footprint, ameliorating stakeholder quality of living, and mitigating social risk.

Given its material impact on bottom lines, social responsibility became essential to supply chain sustainability strategies. The authors of this paper reviewed the relevant literature and discovered its reliance on approaches like corporate social responsibility and its marginalization of systems thinking. This situation undermines the contributions of this literature, as it could be reductionist from a systemic perspective. Reductionism limits solutions to suboptimizations incapable of achieving multifinal and holistic outcomes. To assess this literature, the authors conducted a mapping study to analyse its distribution over four systemic paradigms: functionalism, interpretivism, emancipation, and postmodernism. The results showed that it clustered unevenly around these paradigms and lacked pluralism in perspective. This paper is significant as it revealed the innate inability of most of the supply chain social responsibility literature in offering creative and holistic solutions. Therefore, this literature can only resolve some social responsibility factors allowing the persistence and resurfacing of social responsibility messes.

In order to aid organisations in the adoption of enterprise architecture (EA) best practices, maturity models have been proposed in the literature. These models offer organisational roadmaps and assessment frameworks for increasing EA maturity. However, key questions concerning the implied meaning of the term maturity in the context of these models have been left unexplored by previous research. This research, aided by the field of organisational learning, offers new insights into the implied assumptions of current EA maturity models and offers initial concepts and constructs to guide the conceptualisation, construction and refinement of enterprise maturity models.
