Abstract
Conceptual design is important in that it determines the creativity of products, which is key to the competition of the product market and the function and cost of product are mainly determined in this phase. At the same time it is complex in that it involves the consideration of many different fields in the whole design process. Studying some computer supported cooperative techniques to support effective conceptual design activity is absolutely necessary. This paper presents the models and tools of computer supported cooperative conceptual design (CSCCD) which includes an auto‐resolving model, a human‐human interaction model, automatic cooperation tools and interactive cooperation tools. Experiments have been carried out in the conceptual design of a motorcycle to put the above theories into application.

Abstract
Purpose
The independence and well-being of people with dementia can be significantly influenced by the design of the physical environments around them. Several assessment tools exist to evaluate the dementia design quality of existing residential aged care facilities but, to date, none have been formally identified as suitable for use during the design process. This paper aims to examine the feasibility of re-purposing existing post-occupancy tools for use during the design process, while mapping the influence of design stages on resulting dementia design quality.
Design/methodology/approach
Literature searches identified audit tools for residential aged care settings. After reliability screening, three tools were analysed in-depth, mapping their suitability for use during the design process.
Findings
The study confirmed that existing tools can be re-purposed for design stage use and identified that early design stages have a larger influence on overall dementia design quality than previously thought.
Research limitations/implications
Non-English language publications were not reviewed. Searches may not have identified other existing audit tools for residential care environments.
Practical implications
The ability to assess proposals at key stages of design may help improve the dementia design quality of future residential aged care environments – potentially enhancing the lives of ever-larger numbers of people with dementia.
Originality/value
According to the authors’ knowledge, this is the first known paper to consider formal design-stage evaluation of dementia design quality and the first to identify the relative influence of key stages of design on the resulting dementia design quality.

Abstract
Some industrial organizations using computer‐integrated manufacturing (CIM) for managing intelligent product and process data during a concurrent processing are facing acute implementation difficulties. Some of the difficulties are due to the fact that CIM – in the current form – is not able to adequately address knowledge management and concurrent engineering (CE) issues. Also, with CIM, it is not possible to solve problems related to decision and control even though there has been an increasing interest in subjects like artificial intelligence (AI), knowledge‐based systems (KBS), expert systems, etc. In order to improve the productivity gain through CIM, EDS focused its information technology (IT) vision on the combined potential of concurrent engineering (CE), knowledge management (KM) and computer‐integrated manufacturing (CIM) technologies. EDS – through a number of IT and CIM implementations – realized that CE, KM and CIM do go hand‐in‐hand. The three together provide a formidable base, which is called intelligent information system (IIS) in this paper. Describes the rationales used for creating an IIS framework at EDS, its usefulness to our clients and a make‐up of this emerging IIS framework for integrated product development.

Abstract
Purpose
In performative architectural design, daylighting is a crucial design consideration; however, the evaluation of daylighting in the design process can be challenging. Immersive environments (IEs) can create a dynamic, multi-sensory, first-person view in computer-generated environments, and can improve designers' visual perception and awareness during performative design processes. This research addresses the need for interactive and integrated design tools for IEs toward better-performing architectural solutions in terms of daylighting illumination. In this context, building information modeling and performance simulations are identified as critical technologies to be integrated into performative architectural design.
Design/methodology/approach
This research adopts a design science research (DSR) methodology involving an iterative process of development, validation and improvement of a novel and immersive tool, HoloArch, that supports design development during daylighting-informed design processes. HoloArch was implemented in a game engine during a spiral software development process. HoloArch allows users to interact with, visualize, modify and explore architectural models. The evaluation is performed in two workshops and a user study. A hybrid approach that combines qualitative and quantitative data collection was adopted for evaluation. Qualitative data analyses involve interviews, while quantitative data analyses involve both daylighting simulations and questionnaires (e.g. technology acceptance model (TAM), presence and system usability scale (SUS)).
Findings
According to the questionnaire results, HoloArch had 92/100 for SUS, a mean value of 120.4 for presence questionnaire (PQ) and 9.4/10 for TAM. According to the simulation results, all participants improved the given building's daylighting performance using HoloArch. The interviews also indicated that HoloArch is an effective design tool in terms of augmented perception, continuous design processes, performative daylighting design and model interaction. However, challenges still remain regarding the complete integration of tools and simultaneous simulation visualization. The study concludes that IEs hold promising potentials where performative design actions at conceptual, spatial and architectural domains can take place interactively and simultaneously with immediate feedback.
Originality/value
The research integrates building information modeling (BIM), performative daylighting simulations and IEs in an interactive environment for the identification of potentials and limitations in performative architectural design. Different from existing immersive tools for architecture, HoloArch offers a continuous bidirectional workflow between BIM tools and IEs.

Abstract
Purpose
To be successful, pervasive computing requires a balance of computing, design, and business requirements to be considered throughout the design process. Achieving this synthesis requires a level of interdisciplinary design that is not present in current pervasive design tools. To understand the state of the art and provide insight to future tool designers, the purpose of this paper is to present a survey of design tools for pervasive computing and consider their ability to be used in interdisciplinary design.
Design/methodology/approach
The authors have performed a survey of tools covering many areas within pervasive computing and have evaluated the abilities of each tool with established metrics for pervasive design tools.
Findings
While the paper has found many design tools are available for constructive pervasive applications, few are suitable through all phases of the design cycle or useful across all the intended application domains of pervasive computing.
Originality/value
This survey provides an understanding of the state of pervasive design tools, with regards to interdisciplinary design, which has not previously been performed. Additionally, the authors provide evaluations of the pervasive tools when used in an interdisciplinary setting. These evaluations provide insight to key metrics and allow tool designers to understand the needs of their intended audience.

Abstract
Purpose
The purpose of this paper is to identify interdependent barriers to the search and selection of new technologies by design engineers at industry, organisation and individual levels. A “proof of concept” HyCon tool is presented to demonstrate the role of information technology design support tools in supporting designers to overcome these inhibitors, in this case for hybrid concrete, by providing immersive and interactive, information‐rich environments to explore design solutions.
Design/methodology/approach
The HyCon tool was developed through a prototyping methodology encompassing a testing, analysis, design and coding iterative cycle. This was supported by case studies and industry workshops.
Findings
The results of a collaborative research project are presented, which describes the HyCon design support tool to promote the understanding and use of hybrid concrete in structural frames. This tool is built around a knowledge creation, application, storage, and retrieval cycle to envision and support the use of this new technology.
Originality/value
This paper fulfils an identified need to integrate technology management and design process considerations within the context of an information technology design support tool, and offers a “proof of concept” HyCon tool to demonstrate key issues and potential utilities and applications.

Abstract
Purpose
To deal with the present situation and recover after the COVID-19 pandemic, construction firms are required to recognise the trends in construction supply chain management (CSCM) for the upcoming years and determine the appropriate practices towards the trends for the improvement of construction activities in terms of strategy, tactic and operations. This paper aims to recognise key trends in CSCM and uses these trends as strategic criteria for the evaluation and prioritisation of lean construction (LC) tools at different project phases including design and architectural engineering, planning and control, on-site construction and safety management.
Design/methodology/approach
The integrated analytic hierarchy process–Delphi method is used to collect and analyse the data from construction experts to evaluate the importance levels of the CSCM trends and recommend the appropriate tools for LC practices to improve project performances.
Findings
Seven key CSCM trends are identified: lean supply chain management (SCM), supply chain (SC) integration, SC standardisation, SC problem-solving, SC information-sharing, SC flexibility and SC sustainability. Based on these trends, a set of prioritised lean tools are suggested for LC practices, in which “virtual design construction” (VDC) and “last planner system” are considered as the central tools. These two LC practices can be integrated with other effective tools to support the strategic, tactical and operational targets in construction supply chain (CSC) projects.
Research limitations/implications
This study gives the managerial implications by developing an application framework of LC practices for CSC projects. The framework promotes “VDC” as a strategic tool for the phase of design and architectural engineering and considers “last planner system” as the central LC practice for the phase of project planning and control. The framework also focuses on the improvement of efficiency in construction operations by taking into account the aspects of on-site collaboration, problem-solving, improvement and safety.
Originality/value
Up to date, there is still a lack of researches in classifying and prioritising the significant LC tools for each project phase to deal with CSC issues in both breadth and depth. Thus, this study is performed to provide construction managers with the awareness of CSCM trends on which they can focus to have strategic criteria for selecting LC practices to improve CSC performances.

Abstract
Purpose
Introducing technology at work presents a special challenge as learning is tightly integrated with workplace practices. Current design-based research (DBR) methods are focused on formal learning context and often questioned for a lack of yielding traceable research insights. This paper aims to propose a method that extends DBR by understanding tools as sociocultural artefacts, co-designing affordances and systematically studying their adoption in practice.
Design/methodology/approach
The iterative practice-centred method allows the co-design of cognitive tools in DBR, makes assumptions and design decisions traceable and builds convergent evidence by consistently analysing how affordances are appropriated. This is demonstrated in the context of health-care professionals’ informal learning, and how they make sense of their experiences. The authors report an 18-month DBR case study of using various prototypes and testing the designs with practitioners through various data collection means.
Findings
By considering the cognitive level in the analysis of appropriation, the authors came to an understanding of how professionals cope with pressure in the health-care domain (domain insight); a prototype with concrete design decisions (design insight); and an understanding of how memory and sensemaking processes interact when cognitive tools are used to elaborate representations of informal learning needs (theory insight).
Research limitations/implications
The method is validated in one long-term and in-depth case study. While this was necessary to gain an understanding of stakeholder concerns, build trust and apply methods over several iterations, it also potentially limits this.
Originality/value
Besides generating traceable research insights, the proposed DBR method allows to design technology-enhanced learning support for working domains and practices. The method is applicable in other domains and in formal learning.

Abstract
Purpose
Over recent years there has been a significant drive away from traditional procurement routes where contractors find themselves with an increasing responsibility for the control of the design – a process they have had little experience in managing. Yet this is an area of significant opportunity for those contractors who can adapt quickly and effectively to the changing construction market. However, many current processes are insufficient to manage today's demanding and fast‐moving projects. This paper aims to address this issue
Design/methodology/approach
The paper reflects on the deployment of a design management training initiative to improve performance in a major UK civil and building design and construction company. It investigates the impact of the training initiative, critical practices and a suite of 25 tools on design management performance across the company. The methodology included a structured questionnaire, design management maturity assessment, semi‐structured interviews and a case study.
Findings
The paper highlights benefits delivered by the initiative as well as the practices and tools crucial to successful design management. A range of implementation barriers that affect the success of design management practices is also highlighted together with strategies used on a design and build project to overcome them.
Originality/value
The paper should be helpful to those involved in design management and the development of tools and practices to improve the performance of companies and project teams.
