Value-driven Security Agreements in Extended Enterprises

Today organizations are highly interconnected in business networks called extended enterprises. This is mostly facilitated by outsourcing and by new economic models based on pay-as-you-go billing; all supported by IT-as-a-service. Although outsourcing has been around for some time, what is now new is the fact that organizations are increasingly outsourcing critical business processes, engaging on complex service bundles, and moving infrastructure and their management to the custody of third parties. Although this gives competitive advantage by reducing cost and increasing flexibility, it increases security risks by eroding security perimeters that used to separate insiders with security privileges from outsiders without security privileges. The classical security distinction between insiders and outsiders is supplemented with a third category of threat agents, namely external insiders, who are not subject to the internal control of an organization but yet have some access privileges to its resources that normal outsiders do not have. Protection against external insiders requires security agreements between organizations in an extended enterprise. Currently, there is no practical method that allows security officers to specify such requirements. In this paper we provide a method for modeling an extended enterprise architecture, identifying external insider roles, and for specifying security requirements that mitigate security threats posed by these roles. We illustrate our method with a realistic example

Design as communication in micro-strategy — strategic sensemaking and sensegiving mediated through designed artefacts.

This paper relates key concepts of strategic cognition in microstrategy to design practice. It considers the potential roles of designers' output in strategic sensemaking and sensegiving. Designed artifacts play well-known roles as communication media; sketches, renderings, models, and prototypes are created to explore and test possibilities and to communicate these options within and outside the design team. This article draws on design and strategy literature to propose that designed artifacts can and do play a role as symbolic communication resources in sensemaking and sensegiving activities that impact strategic decision making and change. Extracts from interviews with three designers serve as illustrative examples. This article is a call for further empirical exploration of such a complex subject

Competing institutional trajectories in organization.

Our paper is based on an ethnographic approach. One of the authors has conducted an ethnographic study at TechCo, a multinational aeronautic company, during 4 months. Following the actors, actants and allies at TechCo, we will show that two institutional trajectories compete for controlling the organization. Financial and technical rationales confront each other in order to control TechCo. Those two rationales or institutional trajectories are supported by discourses, inscriptions or managerial devices. By examining those discourses, inscriptions and devices, we will try to enlighten control in action through two competing institutional trajectories – financial and technical. This approach, which we qualify as “controlizing”, is necessary to observe practices in the field. Latour (2002) thus observed the manufacture of law. We have observed here the manufacture of control. Controlizing is characterised by the search for a highly hybrid content more than by the study of actors alone, containers (the tools), processes or outcomes.Management control; ethnography; Competing trajectories;

Service Value Chains and Effects of Scale

This paper generalizes Porter’s notion of the value chain for the analysis of service industries. The generalization entails that the flow and the physical transformation and assembly of goods that are characteristic of manufacturing are generalized into flows and transformation of data and flows and transformation of the physical and mental condition of people that are characteristic of many service industries. Utility is generalized from utilities of forms and function of goods, characteristic of manufacturing, to utilities of time, place, convenience, speed, safety, entertainment, physical and mental wellbeing, knowledge and mental capacity, funding and assurance. The analysis yields a categorization of industries according to central features of the value adding process. Here, the analysis is used to identify sources of (in)efficiency of scale, scope and experience, along the value chain.Service industries;production structure;economy of scale

The Instrumental Genesis of Collective Activity. The Case of an ERP Implementation in a Large Electricity Producer

Collective activity should be a focal subject to study organizational dynamics, particularly in relation with the implementation of management systems such as ERPs. Collective activity is analyzed here as an ongoing dialogical construction by actors. It is always mediated by signs and particularly by instruments. To design and adapt collective activity, a reflexive dialogical exchange between actors, a “collective activity about collective activity”, mediated by instruments, is necessary: we call it “the instrumental genesis of collective activity”. We analyze the case of an ERP implementation at EDF, a large electricity company, in the purchase and procurement area of the production division. The design and implementation of the new system was not clearly viewed as the instrumental genesis of collective activity. Difficulties appeared particularly for cross-functional cooperation and for the construction of new professional profiles of competence. In the light of this case, we suggest that key conditions for the intelligibility and the actionability of collective activity are the establishment of communities and the hybridization of professional competences.Collective Activity; Collective Sensemaking; Community; Dialogical; ERP; Instruments; Instrumental Genesis of Activity; Interpretation; Sign

Applications of lean thinking: a briefing document

This report has been put together by the Health and Care Infrastructure Research and Innovation Centre (HaCIRIC) at the University of Salford for the Department of Health. The need for the report grew out of two main simple questions, o Is Lean applicable in sectors other than manufacturing? o Can the service delivery sector learn from the success of lean in manufacturing and realise the benefits of its implementation?The aim of the report is to list together examples of lean thinking as it is evidenced in the public and private service sector. Following a review of various sources a catalogue of evidence is put together in an organised manner which demonstrates that Lean principles and techniques, when applied rigorously and throughout an entire organization/unit, they can have a positive impact on productivity, cost, quality, and timely delivery of services

HRM in Service: The Contingencies Abound

[Excerpt] Despite the rapid growth in the diversity of service consumers—both abroad and domestically—theoretical developments regarding this diversity in the service world have lagged far behind those that have characterized the world of manufacturing. With regard to international services, Knight (1999) conducted a review of the literature and concluded that there is an alarming paucity of research on international services management despite the importance of services in the global economy. A large proportion of the research that has been conducted on international services has focused on marketing issues rather than human resource management (HRM) issues. This means that little is known about the cross-cultural applicability of service HRM theories, which have hitherto been developed and tested almost exclusively within the West (mostly within the U.S. context). Similarly, there has been little research on the HRM implications of the growing diversity of service consumers within the U.S. domestic market. Again, much of the research focuses on the challenges associated with simultaneously marketing services to a multicultural customer base, with little or no work focusing on the implications of these challenges for HRM in service firms. Thus, the purpose of our chapter is to introduce a preliminary discussion of the HRM implications of both increased internationalization and domestic diversity for service firms. We begin by presenting a brief synthesis of the services management literature that has been established to date. Readers will note in the synthesis that a number of contingencies with regard to HRM practices have already been introduced especially via definitions of what constitutes service and the role of customers in service production and delivery. We then discuss the potential cross-cultural applicability of these services management principles abroad, and when doing so, we focus primarily on the aspects of services management theories that are laden with Western cultural principles. Next, we discuss parallel challenges faced by service firms as a result of increased diversity within the domestic marketplace and we conclude with some thoughts about the necessity to more explicitly explore the contingent nature of HRM practices
