Interacting Components

SystemCSP is a graphical modeling language based on both CSP and concepts of component-based software development. The component framework of SystemCSP enables specification of both interaction scenarios and relative execution ordering among components. Specification and implementation of interaction among participating components is formalized via the notion of interaction contract. The used approach enables incremental design of execution diagrams by adding restrictions in different interaction diagrams throughout the process of system design. In this way all different diagrams are related into a single formally verifiable system. The concept of reusable formally verifiable interaction contracts is illustrated by designing set of design patterns for typical fault tolerance interaction scenarios

Integrated product relationships management : a model to enable concurrent product design and assembly sequence planning

The paper describes a novel approach to product relationships management in the context of concurrent engineering and product lifecycle management (PLM). Current industrial practices in product data management and manufacturing process management systems require better efficiency, flexibility, and sensitivity in managing product information at various levels of abstraction throughout its lifecycle. The aim of the proposed work is to manage vital yet complex and inherent product relationship information to enable concurrent product design and assembly sequence planning. Indeed, the definition of the product with its assembly sequence requires the management and the understanding of the numerous product relationships, ensuring consistency between the product and its components. This main objective stresses the relational design paradigm by focusing on product relationships along its lifecycle. This paper gives the detailed description of the background and models which highlight the need for a more efficient PLM approach. The proposed theoretical approach is then described in detail. A separate paper will focus on the implementation of the proposed approach in a PLM-based application, and an in-depth case study to evaluate the implementation of the novel approach will also be given

A relational insight of brand personification in business-to-business markets

Customers find it difficult to differentiate between competing products based on their functional aspects. The shortening life cycle of products due to quick adoption of technological innovations by competitors makes it difficult for them to identify products based on specifications. The contemporary academic literature related to relationship marketing and brand management is passionate about customer and consumer psychology but little attention has been given to the brand selection criteria of resellers as business customers of the brand. This paper combines branding and relationship marketing as two broad functions of marketing. The paper argues upon the role of human representatives of the brand as brand personified in managing these two functions of marketing in business-to-business markets. The proposal of the paper is to use human representatives as a tool for the execution of relationship marketing and branding strategies. The objective behind using human representatives is to maximize the mindshare of resellers towards the brand and create value for them beyond products and service

Leadership and innovation lessons from professional services firms

This paper compares and contrasts higher education with professional services firms. It considers what (if anything) leaders in higher education may gain from reflecting on how other sectors are evolving and the extent to which lessons can be learned by looking outwards. We structure the paper by outlining the world of PSFs, its many manifestations and some of the current challenges in Section 2. We then move on to compare and interpret one particular leadership framework we developed to understand PSFs, and use this to identify some potential questions for higher education leaders. Finally, we conclude by exploring how, in the light of some of the current drivers of change, our view of the higher education sector may evolve as a new ‘eco-system’ emerges

A Conceptual Framework of Reverse Logistics Impact on Firm Performance

This study aims to examine the reverse logistics factors that impact upon firm performance. We review reverse logistics factors under three research streams: (a) resource-based view of the firm, including: Firm strategy, Operations management, and Customer loyalty (b) relational theory, including: Supply chain efficiency, Supply chain collaboration, and institutional theory, including: Government support and Cultural alignment. We measured firm performance with 5 measures: profitability, cost, innovativeness, perceived competitive advantage, and perceived customer satisfaction. We discuss implications for research, policy and practice

Voice Flows To And Around Leaders: Understanding When Units Are Helped Or Hurt By Employee Voice

In two studies, we develop and test theory about the relationship between speaking up, one type of organizational citizenship behavior, and unit performance by accounting for where employee voice is flowing. Results from a qualitative study of managers and professionals across a variety of industries suggest that voice to targets at different formal power levels (peers or superiors) and locations in the organization (inside or outside a focal unit) differs systematically in terms of its usefulness in generating actions to a unit's benefit on the issues raised and in the likely information value of the ideas expressed. We then theorize how distinct voice flows should be differentially related to unit performance based on these core characteristics and test our hypotheses using time-lagged field data from 801 employees and their managers in 93 units across nine North American credit unions. Results demonstrate that voice flows are positively related to a unit's effectiveness when they are targeted at the focal leader of that unitwho should be able to take actionwhether from that leader's own subordinates or those in other units, and negatively related to a unit's effectiveness when they are targeted at coworkers who have little power to effect change. Together, these studies provide a structural framework for studying the nature and impact of multiple voice flows, some along formal reporting lines and others that reflect the informal communication structure within organizations. This research demonstrates that understanding the potential performance benefits and costs of voice for leaders and their units requires attention to the structure and complexity of multiple voice flows rather than to an undifferentiated amount of voice.Business Administratio

The influence of a collaborative procurement approach using integrated design in construction on project team performance

Purpose – The purpose of the paper is to study the influence of procurement on the performance of integrated design teams. Design/methodology/approach – The research paradigm is based on Russian socio-constructivist approach to activity theory. Activity theory, as opposed to natural or social science, is a design science approach that focuses on the context aspect of project. A triangulation of qualitative research methods is used to investigate the dynamic of integrated teams in two different procurement contexts. Findings – The paper is conclusive regarding the influence of procurement on team efficiency. It demonstrates that traditional procurement processes reinforce socio-cognitive barriers that hinder team efficiency. It also illustrates how new procurement modes can transform the dynamic of relationships between the client and the members of the supply chain, and have a positive impact on teamperformance. Practical implications – The paper demonstrates first that problems with integrated design team efficiency are related to context and not process – they are not technical but socio-cognitive; second that fragmented transactional contracting increases socio-cognitive barriers that hinder integrated design team performance; third that new forms of relational contracting may help to mitigate socio-cognitive barriers and improve integrated design team performance, fourth that changing the context through procurement does not address the problem of obsolete design practices. Originality/value – The paper brings together theories of production in lean construction and social learning as a rival approach to traditional project management theory for demonstrating the importance of context on team performance
