DRIVING NPD PERFORMANCE IN HIGH-TECH SMES THROUGH IT AMBIDEXTERITY: UNVEILING THE INFLUENCE OF LEADERSHIP DECISION-MAKING STYLES
The scarcity of IT resources and technological advancements in high-tech small and medium enterprises (SMEs) require leaders to embed IT ambidexterity – simultaneous pursuit of IT exploitation and IT exploration activities – into their organization’s strategy, which could be challenging. To better understand how leaders enable IT ambidexterity, this study focuses on the leadership decision-making style (directive decision-making and participative decision-making) as a key driving factor. Moreover, we examine how and when leadership decision-making styles are most effective in enacting IT ambidexterity by considering new product development (NPD) team diversity and shared vision as two important contingencies. Finally, we test the role of IT ambidexterity in improving NPD performance. We analyse our research model using survey data from 292 high-tech SMEs. Our findings suggest that both decision-making styles enable IT ambidexterity, however, participative decision-making style is more effective in highly diverse NPD teams and directive decision-making style should be preferred when shared vision is a dominant factor among NPD team members. Our results also show that IT ambidexterity significantly enhances NPD performance. We discuss our contribution to information systems (IS) and ambidexterity research and provide implications for practice
Learning the What and How of Annotation in Video Object Segmentation
Video Object Segmentation (VOS) is crucial for several applications, from
video editing to video data generation. Training a VOS model requires an
abundance of manually labeled training videos. The de-facto traditional way of
annotating objects requires humans to draw detailed segmentation masks on the
target objects at each video frame. This annotation process, however, is
tedious and time-consuming. To reduce this annotation cost, in this paper, we
propose EVA-VOS, a human-in-the-loop annotation framework for video object
segmentation. Unlike the traditional approach, we introduce an agent that
predicts iteratively both which frame ("What") to annotate and which annotation
type ("How") to use. Then, the annotator annotates only the selected frame that
is used to update a VOS module, leading to significant gains in annotation
time. We conduct experiments on the MOSE and the DAVIS datasets and we show
that: (a) EVA-VOS leads to masks with accuracy close to the human agreement
3.5x faster than the standard way of annotating videos; (b) our frame selection
achieves state-of-the-art performance; (c) EVA-VOS yields significant
performance gains in terms of annotation time compared to all other methods and
baselines.Comment: Accepted to WACV 202

The institutional politics of change in an outsourced project
This paper focuses on unique longitudinal research within a multi-vendor outsourcing environment in the European Defence Sector. It describes the unfolding relationship between vendors and a major defence organization as the vendors developed, implemented and then managed a human resource management (HRM) system. This paper examines the apparent paradox between the wide scale adoption of outsourcing and its relatively poor performance and outcomes. The research suggests this comes from a loose coupling between the rational logic of outsourcing practice and the interpretation and enactment by interest groups that is exaggerated by the imposition of fixed deadlines and strong contractual governance
Towards next generation of Manufacturing: Implications of Big Data and Digitalization in the context of Industry 4.0
Antecedents of low carbon emissions supply chains
Purpose: A low-carbon economy is the pressing need of the hour. Despite several efforts taken by the government and large corporations, there is still research to be conducted exploring the role of top management commitment in translating external pressures into responses that help to build low-carbon emissions in supply chains.
Design/methodology/approach: The authors have grounded their framework in institutional theory, agency theory and contingency theory. On the basis of existing literature, four hypotheses were drawn. To test these hypotheses, a questionnaire was developed and pre-tested. Finally, statistical analyses were performed to test the research hypotheses using 176 samples gathered using a pre-tested questionnaire following Dillman’s (2007) total design test method.
Findings: The results suggest that coercive pressures and mimetic pressures under the mediating effect of top management commitment have a significant influence on organizational response to low-carbon emissions. The authors further note that supply base complexity has moderating effects on the link between top management commitment and organizational response towards low-carbon emissions.
Originality/value: This study offers valuable insights to those managers and environmental consultants who view supply base complexity as a limitation. However, the results indicate that supply base complexity may help to enhance the effectiveness of the top management commitment on organizational response towards low-carbon emissions
World Class Sustainable Supply Chain Management: critical review and further research directions
Purpose
Sustainable supply chain management (SSCM) has attracted considerable interest among academics and practitioners. The purpose of this paper is to present a critical review of the literature, to identify missing links, to argue for the use of world class SSCM (WCSSCM) through a framework, and suggest further research directions.
Design/methodology/approach
In the paper the authors have undertaken an extensive review of literature and classified articles using a novel classification scheme.
Findings
Through the extensive review and identification of research gaps, the paper identifies significant differences between definitions and methodologies in the SSCM literature; and argues for “WCSSCM.” This term is elaborated on via a theoretical framework in which 18 dimensions are classified under six constructs of SSCM. Furthermore, a list of potential research directions for WCSSCM is discussed.
Research limitations/implications
The research is an attempt to critically review literature, argue for WCSSCM, and develop a theoretical framework.
Originality/value
The paper offers a new approach to SSCM literature, arguing for WCSSCM through a framework, and providing further research directions
Twenty-first century supply chain management: a multiple case study analysis within the UK aerospace industry
In recent years, to stimulate the development of Lean Supply Chain Management (SCM) in SMEs, the UK aerospace industry has developed a change programme named “Supply Chains for the 21st century” (SC21). This programme promotes the use of a simple standard improvement framework, which defines performance goals and standardizes the approaches and tools for continuous sustainable improvement. However, its effective impact on Lean SCM and performance measurement systems (PMS) has not been widely covered in the literature. Adopting a qualitative research methodology approach, this study investigates five significant organizations to explore and contribute to knowledge on Lean SCM and PMS challenges related to the adoption of the SC21 programme. From an academic point of view, the paper highlights the key role of SC21 in accelerating the competitiveness of the aerospace industry by fostering managerial development of supply chain partners. In particular, it highlights the importance of PMS as well as collaboration between supply chain partners for efficient and effective SCM. From a practitioner’s perspective, the SC21 performance award is highlighted as a very successful approach in bridging the gap of differing agendas between supply chain partners. SMEs, with support from their larger supply chain partners, can embrace performance measurement practices to improve their performance. More established SMEs with a headcount of more than 50 employees are capable of developing and documenting strategic plans and more sophisticated PMS
