A lean way of design and production for healthcare construction projects

As a consequence of the lack of solid conceptual foundation, the project management concepts and techniques usually applied within the construction sector are fragmented and have proved to be incapable of solving the complex problems of design management. As a result, healthcare providers have become frustrated with the outcomes such as cost and schedule overruns, accidents, less than expected quality and inadequate functionality. However, an investigation of successful healthcare projects reveals that new approaches have been developed to tackle such problems. This study uses recent data based on six construction projects. The idea is demonstrate how successful projects are dealing with the integration between design, production, and operations, through an appropriate approach to the management of production systems. The paper aims to assist the different parties of the AEC industry to better understand how practices applied into design phase could support the efficiency in the management of production systems

Lean knowledge management : the problem of value

Lean knowledge management is defined here as: getting the right information, in the right form, to the right people at the right time. This definition highlights series of practical problems for knowledge management in the built environment which, in turn, have implications for lean theory. In the terms of TFV theory, the problems that arise from getting information to the right people at the right time are essentially flow (F) issues, but those that are concerned with defining the right information and the form in which it is to be delivered are more concerned with value (V). Here, we focus primarily on the problem of defining right information. A distinction is made between sociological 'values' and economic 'value', showing how both relate to production theory. In the course of benefits capture and realisation, both values and value are negotiated between project participants and other stakeholders. It is argued that these processes are best conceived as conversations and that this is implied in the basic formulation of V theory. The notion of objectivity and its significance for these values/value negotiations is examined. The problem of benefits realisation is considered and a set of hypotheses are generated regarding the nature of an effective benefits realization management process

The interaction of lean and building information modeling in construction

Lean construction and Building Information Modeling are quite different initiatives, but both are having profound impacts on the construction industry. A rigorous analysis of the myriad specific interactions between them indicates that a synergy exists which, if properly understood in theoretical terms, can be exploited to improve construction processes beyond the degree to which it might be improved by application of either of these paradigms independently. Using a matrix that juxtaposes BIM functionalities with prescriptive lean construction principles, fifty-six interactions have been identified, all but four of which represent constructive interaction. Although evidence for the majority of these has been found, the matrix is not considered complete, but rather a framework for research to explore the degree of validity of the interactions. Construction executives, managers, designers and developers of IT systems for construction can also benefit from the framework as an aid to recognizing the potential synergies when planning their lean and BIM adoption strategies

Design management: changing roles of the professions

This paper sets out to explore how recent changes in procurement in construction have affected the roles that professions play in the design process. It discusses how professions that traditionally took the role of design manager now find themselves participating within previously unforeseen contexts, working in multidisciplinary teams led by contractors and with changed responsibilities at the design stage. Supply chain members who were not previously involved during the early project phases are being engaged at the earliest phases of the project life cycle and even taking leadership roles while designers sometimes work as supply chain partners. A study of design in construction and other sectors shows that in dealing with design management issues it is critical to deepen appreciation for the unique characteristics of design and the design process. The paper argues that contractors and designers taking on design management roles in a dynamic industry seeking to explore best practice and innovative approaches to procurement and in the delivery of projects need to acquire new skills, management education and develop the necessary qualities

Models and metaphors: complexity theory and through-life management in the built environment

Complexity thinking may have both modelling and metaphorical applications in the through-life management of the built environment. These two distinct approaches are examined and compared. In the first instance, some of the sources of complexity in the design, construction and maintenance of the built environment are identified. The metaphorical use of complexity in management thinking and its application in the built environment are briefly examined. This is followed by an exploration of modelling techniques relevant to built environment concerns. Non-linear and complex mathematical techniques such as fuzzy logic, cellular automata and attractors, may be applicable to their analysis. Existing software tools are identified and examples of successful built environment applications of complexity modelling are given. Some issues that arise include the definition of phenomena in a mathematically usable way, the functionality of available software and the possibility of going beyond representational modelling. Further questions arising from the application of complexity thinking are discussed, including the possibilities for confusion that arise from the use of metaphor. The metaphor of a 'commentary machine' is suggested as a possible way forward and it is suggested that an appropriate linguistic analysis can in certain situations reduce perceived complexity

A qualitative interview study comparing and contrasting resident and staff perspectives of engaging in meaningful activity in a UK care home.

The provision of meaningful activities in care homes is essential for maintaining residents' mental and physical health, yet many do not get adequate opportunities to participate. This qualitative study explored resident and staff perceptions of engaging in meaningful activities in a residential care home for older people (aged over 65 years) in South London, UK. Nine residents and eleven staff members were recruited and their experiences explored through semi-structured interviews. Data were analysed thematically, and three themes emerged. (1) Appreciation of activity: both staff and residents were aware of the benefits of activity to physical and mental health, yet there was a lack of provision within the home. (2) Residents' desire for engagement: residents perceived themselves as active individuals who had previously enjoyed activities, and had goals that they wanted to achieve. This was in contrast to views of care staff, who perceived residents as inactive, lacking in motivation and sedentary due to intrinsic factors such as their age. (3) Impact of care home culture and physical space: staff and residents perceived different barriers to activity; staff reported they were often expected to take on multiple roles within the home leading to a lack of time to engage residents in activities, whilst residents perceived that the layout and design of the home hindered provision. It was concluded that comparing and contrasting views of residents and staff could assist residential homes to reach greater levels of shared understanding of activity provision and highlight particular areas to target for increasing activity engagement

Smart homes and their users:a systematic analysis and key challenges

Published research on smart homes and their users is growing exponentially, yet a clear understanding of who these users are and how they might use smart home technologies is missing from a field being overwhelmingly pushed by technology developers. Through a systematic analysis of peer-reviewed literature on smart homes and their users, this paper takes stock of the dominant research themes and the linkages and disconnects between them. Key findings within each of nine themes are analysed, grouped into three: (1) views of the smart home-functional, instrumental, socio-technical; (2) users and the use of the smart home-prospective users, interactions and decisions, using technologies in the home; and (3) challenges for realising the smart home-hardware and software, design, domestication. These themes are integrated into an organising framework for future research that identifies the presence or absence of cross-cutting relationships between different understandings of smart homes and their users. The usefulness of the organising framework is illustrated in relation to two major concerns-privacy and control-that have been narrowly interpreted to date, precluding deeper insights and potential solutions. Future research on smart homes and their users can benefit by exploring and developing cross-cutting relationships between the research themes identified
