Abstract

Purpose

Briefing in a project delivery context is one of the most critical factors in the project success. It defines client requirements, translates these needs into design criteria and generates a design concept. A lack of briefing clarity is one of the main causes of design changes and may lead to project cost and time overruns. This research aims to assess the brief clarity and its influence on project cost and duration.

Design/methodology/approach

This research created the PDRI-SD technique by utilising a system dynamic (SD) approach and project definition rating index (PDRI) tool to model the complex system of project briefing and associated variables. Stock and flow diagrams of the main subsystems including the briefing, the detailed design and the construction process, were developed to assess the influence of brief clarity on project cost and time. The PDRI was adopted to measure the briefing clarity and apply in the model. PDRI-SD was then tested in Australian building refurbishment projects to assess the model's effectiveness.

Findings

The simulation results indicated that a minor reduction of the lack of clarity throughout the initial briefing process could significantly mitigate unpredicted delay and cost overruns during the detailed design and the construction stage.

Originality/value

This research contributed to the existing body of knowledge by developing an effective technique to measure the impact of lack of brief clarity on project cost and time performance. PDRI-SD can also aid project clients to predict the influence of the initial defined brief on the detailed design and construction process using the historical data of similar previous projects. It provides clients with feedback, indicating whether the brief meets project requirements or whether parts of the project brief require more clarification/rectification before the project handover to the builders.

Abstract

Purpose

To facilitate the choice of the winning bid in the public procurement of bus transports in Sweden and to make sure that the winning bid has the qualities that are requested, the placed demands are very detailed. On the other hand, the detailed demands will lead to limitations and could force the operator to use less environmentally friendly alternatives. The purpose of this paper is to identify factors regarding the buses and their properties that are commonly used in the public procurement process and analyze their level of details.

Design/methodology/approach

The method is to collect and study foundations from the process of public procurement of bus transport for three years in Sweden.

Findings

The result shows the most common and relevant aspects regarding the buses and their properties that have been requested and taken into consideration when creating the final contracts. Most of the demands regarding the factors were also described in very great detail.

Research limitations/implications

The study is done with data from three years. The demands have only been classified on two levels: detailed and non‐detailed.

Practical implications

The results enlighten the amount of demands that are specified in the foundations for public procurement of bus transports. While these demands make the base for the contracts, they are important for the decision makers in public transports.

Originality/value

The paper shows a general overview of hard and soft demands regarding factors that have been expressed in the foundations for public procurement of bus transports for the previous three years.

Abstract

Involvement in the effective design and use of computer‐based information systems is essential for the manager of the 1990s. To be most effective, systems must be designed for the requirements of the manager‐user. Too often there is a communication gap between managers who are too busy, uninterested or unwilling to become directly involved, on the one hand, and on the other, the consultant who is more usually engrossed in the special nature of the system. The author aims to provide an up‐to‐date and integrated treatment of organisation and management, as well as to emphasise the utilisation of management information systems to improve the art of managing.

Abstract

Purpose

The purpose of this paper is to investigate how to measure collaborative design performance and, in turn, improve the final design output during a design process, with a clear objective to develop a design performance measurement (DPM) matrix to measure design project team members' design collaboration performances.

Design/methodology/approach

The methodology adopted in this research uses critical literature reviews, in‐depth focus group interviews and a questionnaire survey.

Findings

The main finding of this study is a DPM matrix that addresses five DPM indicators: efficiency, effectiveness, collaboration, management skill, and innovation, and 25 detailed DPM criteria. It was found that decision‐making efficiency is the most important DPM criterion for collaborative design efficiency; plus delivering to the brief for effectiveness; clear team goal/objectives for collaboration; decision‐making ability for management skill; and competitive advantage for innovation.

Research limitations/implications

As the present study was focused on exploring DPM during a design process, some key DPM criteria which are not measurable during a design development process were not included in this study. The proposed multi‐feedback approach for DPM matrix implementation needs to be validated in future research.

Practical implications

The DPM matrix can be applied to support a design manager in measuring and improving collaborative design performance during a design process, by reviewing and modifying collaborative design development, identifying the design team strengths and weaknesses, improving team communication, and suggesting suitable responsive actions.

Originality/value

The major contribution of this study is the investigation and development of a DPM matrix to measure collaborative design performance during a design process.

Abstract

Purpose

The lightweight design of aircraft seats can significantly improve fuel efficiency and reduce greenhouse gas emissions. Metal additive manufacturing (MAM) can produce lightweight topology-optimized designs with improved performance, but limited build volume restricts the printing of large components. The purpose of this paper is to design a lightweight aircraft seat leg structure using topology optimization (TO) and MAM with build volume restrictions, while satisfying structural airworthiness certification requirements.

Design/methodology/approach

TO was used to determine a lightweight conceptual design for the seat leg structure. The conceptual design was decomposed to meet the machine build volume, a detailed CAD assembly was designed and print orientation was selected for each component. Static and dynamic verification was performed, the design was updated to meet the structural requirements and a prototype was manufactured.

Findings

The final topology-optimized seat leg structure was decomposed into three parts, yielding a 57% reduction in the number of parts compared to a reference design. In addition, the design achieved an 8.5% mass reduction while satisfying structural requirements for airworthiness certification.

Originality/value

To the best of the authors’ knowledge, this study is the first paper to design an aircraft seat leg structure manufactured with MAM using a rigorous TO approach. The resultant design reduces mass and part count compared to a reference design and is verified with respect to real-world aircraft certification requirements.

Abstract

In the continuing endeavour to work towards ever better management, experience plays a crucial role. We learn from success, but we can learn much more from failure. Further, it is far better and cheaper when we learn from other people′s failures rather than our own. This monograph assesses the requirements of project management in relation to industrial projects, illustrating the factors that can result in failure by means of a series of case studies of completed and abandoned projects worldwide that have failed in one way or another. The key roles played by project planning and project cost control in meeting and overcoming the practical problems in the management of industrial projects are examined in detail. In conclusion the lessons that can be learned are evaluated and presented, so that we may listen and learn – if only we will.

Abstract

Discusses the issue of developing a project design that adequately addresses the practicality of delivering integrated construction knowledge and experience in planning, engineering, procurement and field operations. There are few practical examples in the literature that explain how non‐traditional construction project procurement approaches can be utilised to organise an integrated project management system incorporating occupational health and safety (OHS), environmental management (EM) and quality management (QM) systems. Reports on a case study that helps fill that gap. Shows how the adoption of a design and construct procurement approach, together with appropriate management techniques, on a successful major freeway project in Melbourne, Australia, was driven by a sound construction planning process, and integrated the construction planning system with OHS, EM and QM systems.

Abstract

Purpose

Despite appearing in the literature over 10 years ago as a potentially exciting cost management technique, there is still limited agreement about the nature of target costing. The purpose of this study is to explore the characteristics of target costing, and to test whether these characteristics were adopted in three European companies that used target costing.

Design/methodology/approach

This paper draws on case study data, collected at three manufacturing companies (consumer electronics, machinery, and transportation equipment).

Findings

The paper identifies eight characteristics of target costing, based on the early Japanese case descriptions. These characteristics are related to the way a target is set and how progress towards that target is measured. The findings of the case studies confirm these characteristics. However, some differences were found regarding the interpretation of the strict rule that “the target cost cannot be exceeded at product launch”.

Research limitations/implications

The results indicate that future research on the adoption of target costing cannot be disconnected from its characteristics. Further studies might investigate whether degree of openness to suppliers, leadership position, time pressure and position in the supply chain can explain the noted differences in characteristics among companies.

Practical implications

The characteristics identified in this paper provide an aid to researchers and managers considering target costing. Detailed case descriptions provide best practices examples for other companies.

Originality/value

This study is the first empirical paper concerned with describing the typical characteristics of target costing. By exploring the characteristics, we hope to inspire others to further explore this interesting phenomenon.

Abstract

Purpose

Based on social network theory and the literature of contract governance, the purpose of this study is to explore how distributors’ “banding together” (network intensity) affects contract governance (detailed contracts), which, in turn, influences channel conflict and simultaneously tests the moderating effect of network centrality.

Design/methodology/approach

The authors collect the data from the side of 288 manufacturers.

Findings

This study finds that, first, distributors’ network intensity positively affects detailed contracts between manufacturers and distributors; second, detailed contracts, in turn, declines channel conflict; and third, network centrality will weaken the positive influence of network density on detailed contracts. In addition, an ex post analysis finds that detailed contracts play a negative mediating role between distributors’ network density and channel conflict and this negative mediating effect would be weakened by distributors’ network centrality.

Originality/value

The current study not only helps to make up for the shortcomings of using the dyadic analysis paradigm to analyze channel behavior but also helps manufacturers to understand and respond to the phenomenon of distributors’ “banding together” comprehensively and deeply.

Abstract

Purpose

The objective of this research is to develop a structure for a materials supply systems (MSSs) design process to be used during product development projects (PDPs).

Design/methodology/approach

The research is based on a qualitative study at a first tier supplier in the automotive industry. Empirical data were gathered over the course of one year and analysed by means of a previously developed MSSs design model and the company's product development phases.

Findings

A structure for a MSSs design process has been developed, based on the following four phases: planning, concept development, system‐level design and detail design.

Research limitations/implications

Future research could further develop the structure discussed in this paper and complement it with engineering tools for use during the design process.

Practical implications

The results underline the importance of a MSSs design process and emphasise that such a process should cover activities at an early stage of PDPs. Moreover, the necessity of coordinating the specifications of the various materials flows and evaluating the entire MSS before becoming absorbed by detailed design issues is highlighted.

Originality/value

This paper complements the rapidly growing literature on concurrent engineering by emphasising the importance of integrating the materials supply aspects at an early stage of PDPs and designing the MSS in integration with the product and the production system.
