Self-Organizing is not Self-Managing: A Case Study about Governance Challenges in an Agile IT Unit and its Scrum Projects

This paper presents a case study on the internal governance of Scrum projects and their relationships with their organization’s governance within a rich research setting: an IT agile unit and its mature Scrum project teams. This study reveals ambiguities about the meaning of self-organizing versus self-managing, and the associated challenges for governance processes, especially those related to HR governance, which can lead to unresolved issues and conflicts. Interestingly, these ambiguities are also found in the current IS literature, which rarely differentiates self-organizing from self-managing in agile projects. Thus, this paper enhances our knowledge of governance processes and associated challenges, particularly for mature Scrum project teams, which are still little covered in the IS literature

Exploring the future of enterprise architecture : a Zachman perspective

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.http://www.elsevier.com /locate/compind2017-06-30hb2016Industrial and Systems Engineerin

The genome of the yellow potato cyst nematode, Globodera rostochiensis, reveals insights into the basis of parasitism and virulence

BACKGROUND: The yellow potato cyst nematode, Globodera rostochiensis, is a devastating plant pathogen of global economic importance. This biotrophic parasite secretes effectors from pharyngeal glands, some of which were acquired by horizontal gene transfer, to manipulate host processes and promote parasitism. G. rostochiensis is classified into pathotypes with different plant resistance-breaking phenotypes. RESULTS: We generate a high quality genome assembly for G. rostochiensis pathotype Ro1, identify putative effectors and horizontal gene transfer events, map gene expression through the life cycle focusing on key parasitic transitions and sequence the genomes of eight populations including four additional pathotypes to identify variation. Horizontal gene transfer contributes 3.5 % of the predicted genes, of which approximately 8.5 % are deployed as effectors. Over one-third of all effector genes are clustered in 21 putative ‘effector islands’ in the genome. We identify a dorsal gland promoter element motif (termed DOG Box) present upstream in representatives from 26 out of 28 dorsal gland effector families, and predict a putative effector superset associated with this motif. We validate gland cell expression in two novel genes by in situ hybridisation and catalogue dorsal gland promoter element-containing effectors from available cyst nematode genomes. Comparison of effector diversity between pathotypes highlights correlation with plant resistance-breaking. CONCLUSIONS: These G. rostochiensis genome resources will facilitate major advances in understanding nematode plant-parasitism. Dorsal gland promoter element-containing effectors are at the front line of the evolutionary arms race between plant and parasite and the ability to predict gland cell expression a priori promises rapid advances in understanding their roles and mechanisms of action.SE-vdA is supported by BBSRC grant BB/M014207/1.

An exploration of the many ways to approach the discipline of enterprise architecture

Despite growing interest in enterprise architecture (EA) around the world in recent years, a lack of common understanding is frequently described by EA researchers/practitioners. We conducted a systematic mapping study and it revealed that the extent to which the authors/researchers are focused on EA, the sectors in which they are working, the academic disciplines in which they have studied, the countries where their affiliated organizations are located, the subject areas of the journals/publishers of their publications and the way they have approached EA and its practitioners are some major elements that might influence the existing uniformity in EA. In addition, this study demonstrates how important it is to pay attention to the definition of ‘enterprise architecture’ itself. The contribution of this study is the organization of the EA literature according to three major questions concerning ‘who’ have been published in the literature, ‘where’ they have been located and ‘what’ their publications are about. This helps to better identify sources of variety which could be on the basis of the lack of common understanding in EA and provides practitioners and stakeholders a better understanding of this challenge. This also provides relevant directions for future studies

The systemic tenets of the key supply chain social responsibility approaches

Social responsibility issues keep reoccurring despite the popularity of numerous approaches perceived widely as adequate. In this paper, the authors conducted a systematic literature review to explore this phenomenon from a systems thinking standpoint. The findings revealed that each approach is founded on a different systemic paradigm, makes different assumptions on the nature of social responsibility issues, and has different objectives when resolving them. Therefore, employing any of these approaches alone will certainly fail given their underlying systemic limitations. The findings also revealed that these approaches are complementary from a critical systems thinking perspective, hence, researchers and practitioners can use their tools and methods together in the form of tailored interventions to better address efficiency, subjectivity, and fairness when resolving social responsibility issues. This paper concludes by proposing a practical framework based on critical systems practice which encompasses four systemic paradigms allowing the inclusion of a spectrum of perspectives, and assumptions
