The purpose of this paper is to improve the understanding of the role of the bottlenecks in the dynamic software development supply chains. The paper examines the effects of the task priorities in the software development and investigates the possible strategies to manage them effectively.

In this paper, a software development supply chain has been simulated. This includes modeling of the various sizes of software requirement, different priorities, variations in development times, quality defects, etc. The model assumes a fixed set of resources of various skills. The model is studied for the bottlenecks, throughput, work in progress (WIP), etc. under various work preemption scenarios.

The results indicate that job priorities impact the bottleneck formulation, throughput and WIP of the software development. The work interruption policies to accommodate priority jobs adversely impact the throughput. Selective introduction of interruptions by leaving the bottlenecks from interruptions helps balancing the throughput and priorities.

The impact of the learning curve and knowledge acquisition time needed by the resources to restart the interrupted work has not been considered in this paper, which can be a future area of research.

The paper helps the practicing managers evaluate the dynamics of the bottlenecks with various task management approaches and comprehend the possible tradeoffs between priority and throughout.

The paper looks at software development from a perspective of workflow dynamics. This is a pioneer effort, as it utilizes simulation and modeling approach in understanding the software supply chains better.

The purpose of this paper is to discuss the collaborative practices of virtual teams carrying out knowledge‐based work and the tools required/used to assemble “collective” artefacts.

The vast majority of recent work on communities of practice is devoted to community management (i.e. discovering, building, and maintaining communities), dismissing or undermining community practices and how they are technologically mediated (i.e. the practice‐specific tools and artefacts involved). This paper investigates existing practices and makes use of scenarios to envision new distributed collective practices in a designated application domain. The instruments used include both empirical tools (i.e. survey of current practice and expert interviews) and analytical tools (i.e. scenarios of use, walkthroughs, and virtual prototyping) to provide insight towards the design of practice‐oriented toolkits.

The proposed approach is validated in the context of an electronic village of local interest with a thematic focus on regional tourism, highlighting the key role of “collective” knowledge management in information‐based industries whose products are non‐material (intangible) and knowledge is central to gaining competitive advantage. The results include a general model for practice‐oriented toolkits conceived of as separate software components from (but interoperable to) the community support system and devised to establish a place for engaging in the practice the community is about. This model is then used to build an operational toolkit for assembling vacation packages by cross‐organization virtual communities of practice.

Virtual communities of practice (or partnerships) necessitate smooth integration of community management and practice‐specific tasks and tools. Community management tasks can be supported by augmenting capabilities of existing community portals to allow for community registration, role undertaking, declaration of virtual assets, etc. Practice‐oriented tasks should be designed in such a way so as to capture and accommodate domain‐specific vocabulary.

Model‐based techniques and domain‐specific design languages are used as the unifying mechanism (i.e. software factory) for integrating community management and practice‐oriented artefacts. These techniques are designed and implemented into a software platform so as to facilitate the systematic accumulation and reuse of knowledge towards the construction of collective artefacts.

This paper seeks to investigate the work of a small company involved in researching techniques and designing equipment for assembly automation.

The development of a fully automated CNC machine for drilling aircraft wing sub‐assemblies is described. The importance of accurate process simulation is discussed, and a research project combining physics‐based gaming hardware with factory simulation software is presented. Its application to the laying‐up of carbon composite materials is explained.

Effective and affordable simulation software is essential to small companies to avoid risk in one‐off projects. AMTRI leverages new developments and puts them together to form powerful new systems. The automation of innovative composite processing is intrinsically connected with the behaviour of the material itself.

The paper points out the importance of automation to the future of European manufacturing, in the light of increasing fuel costs.

Although not known for his contribution to marketing research, it is undeniable that Sir Francis Bacon was on to something when he observed some 400 years ago that, “knowledge is power”. Firms across the globe have, of course, realized this and made marketing a keystone in their operations. But the advent of new technologies has enabled a heightened ability to channel consumer feedback into the product or service development process. Capturing so much data, in any meaningful way, has been the real challenge, beyond the filling of huge databases with consumer information from loyalty cards, for example. Approaching marketing in a more qualitative way while utilizing this new technology has been a severe test of the marketing functions of many corporations.

Provides strategic insights and practical thinking that have influenced some of the world's leading organizations.

The Kansas City Division of Allied Signal Aerospace operates a flexible manufacturing system which is described. Its components ‐ machining centres, co‐ordinate measuring machines, AGVs and materials handling systems, wash station, central chip and coolant system, systems hardware, control system ‐ are outlined. The process flow activities are described along with the benefits of the system.

The adoption of integrated computer‐based manufacturing and management techniques by small, traditional engineering companies often represents an unaffordable and high risk investment strategy in technology that is often not well understood by its recipients. Paradoxically, the opportunity for complete success in a small to medium‐sized enterprise (SME) is greater than in a large company which very often is incapable of full integration due to the divisions and inertia implicit in a large hierarchical organization. To derive full benefits from such an investment the company must possess a meticulous understanding of its market, fiscal environment, operations management, engineering and technological skills, manufacturing facilities and product range. It must adopt an appropriate implementation of CIM that does not debase previous ad hoc investments in what are often termed islands‐of‐automation or information technology. For success a well‐planned stepwise approach is vital. Reports on the approach adopted by a small to medium‐sized Scottish engineering company specializing in the production of mechanical actuation systems. Over a three‐year period the company embarked on a low‐cost, phased implementation of software and hardware systems that exploit a database to integrate its design, manufacturing the business operations. A major element in these systems is the distributed Command, Communication and Control (C₃) environment which has transformed the effectiveness of operations. The company′s investments were based on a prudent assessment of its current and planned product range, existing and planned manufacturing facilities, the scale of its operations and business objectives.

Software projects are commonly late and over budget, causing the product to be late to market. Based on questionnaires and field research with software managers in Europe, the USA and Japan, seeks to isolate the management practices that accelerate software development. The results suggest that global differences are not pronounced: Japanese software factories have development processes structured similarly to their US and European counterparts; productivity is also roughly equivalent. To reduce development time, software managers currently achieve greater leverage from the management of people and the cross‐functional process than with the use of CASE tools and technology.

This technical paper reports the development of an industrial robotic labeling system, designed to insert identification labels on rolls of paper coming from an industrial paper machine.

The system was developed for an existing installation comprising a paper machine, a roll measuring and weighting station and a roll wrapping machine. The labels identify each roll by means of barcodes, which are used internally in the factory to identify and store each roll at the automatic warehouse and by the customer company for similar purposes.

In describing an industrial application designed for labeling applications, this paper discusses and details a software interface designed to command shop‐floor manufacturing systems remotely from the manufacturing tracking software. This adds in terms of flexibility and agility, since all available operations were implemented in a very general way requiring only simple parameterization to specify the individual operations.

Since the TCP/IP server is a general implementation, using the BSD compatible TCP/IP socket implementation from Microsoft, it can receive commands from virtually any client. This makes this robotic cell interface an interesting way to command shop‐floor manufacturing systems.

Demonstrates a method for controlling shop‐floor manufacturing systems that has broad applications.

Cost-benefit (C/B) analysis helps to determine the economic feasibility of business software investments. Research literature and published practices do not recognize substantial software maintenance costs in C/B analysis. Current analyses emphasize the benefits of an initial investment but do not consider the recurring benefits of each enhancement during the software lifecycle. Such analyses could lead to incorrect investment decisions and lost business opportunities. This article aims to review current research on software lifecycle costs and develop a theoretically sound C/B analysis.

This article reviews current C/B analyses and discusses their shortcomings in treating the significant recurring maintenance costs. It analyzes the findings of various studies on software maintenance and synthesizes these findings to identify the nature of various maintenance costs and their benefits. Based on the synthesis, it theorizes various cost and benefit elements for inclusion in a revised C/B analysis.

This article identifies each recurring maintenance cost relevant to C/B analysis. It also identifies recurring benefits from each enhancement that hitherto have been omitted. Finally, this article discusses how these costs and benefits should be treated in the revised C/Bs analysis.

This is a conceptual paper proposing a new C/B analysis and requires an empirical validation.

This article provides a revision of the C/B analysis that is long overdue. It will help to justify a software investment correctly, rank software projects that compete for limited funds and help create a sound software project portfolio. Since 20% of software products may incur 80% of software investment, this analysis will help to make correct software investments and avoid lost business opportunities. This article also describes a practical method to use the revised C/B analysis.
