Perspectives on experiences of innovation: the development of an assessment methodology appropriate to construction project organizations

The UK construction industry is in the process of trying to adopt a new culture based on the large-scale take up of innovative practices. Through the Demonstration Project process many organizations are implementing changed practices and learning from the experiences of others. This is probably the largest experiment in innovation in any industry in recent times. The long-term success will be measured by the effectiveness of embedding the new practices in the organization. As yet there is no recognized approach to measuring the receptivity of the organization to the innovation process as an indication of the likelihood of long-term development. The development of an appropriate approach is described here. Existing approaches to the measurement of the take up of innovation were reviewed and where appropriate used as the base for the development of a questionnaire. The questionnaire could be applicable to multi-organizational construction project situations such that the output could determine an individual organization's innovative practices via an innovation scorecard, a project team's approach or it could be used to survey a wide cross-section of the industry.

Implementing innovation in construction: Contexts, relative boundedness and actor-network theory

Theoretical understanding of the implementation and use of innovations within construction contexts is discussed and developed. It is argued that both the rhetoric of the 'improvement agenda' within construction and theories of innovation fail to account for the complex contexts and disparate perspectives which characterize construction work. To address this, the concept of relative boundedness is offered. Relatively unbounded innovation is characterized by a lack of a coherent central driving force or mediator with the ability to reconcile potential conflicts and overcome resistance to implementation. This is a situation not exclusive to, but certainly indicative of, much construction project work. Drawing on empirical material from the implementation of new design and coordination technologies on a large construction project, the concept is developed, concentrating on the negotiations and translations implementation mobilized. An actor-network theory (ANT) approach is adopted, which emphasizes the roles that both human actors and non-human agents play in the performance and outcomes of these interactions. Three aspects of how relative boundedness is constituted and affected are described; through the robustness of existing practices and expectations, through the delegation of interests on to technological artefacts and through the mobilization of actors and artefacts to constrain and limit the scope of negotiations over new technology implementation.

Horses for courses: Relating innovation diffusion concepts to the stage of the diffusion process

The research uses a sociological perspective to build an improved, context specific understanding of innovation diffusion within the UK construction industry. It is argued there is an iterative interplay between actors and the social system they occupy that directly influences the diffusion process as well as the methodology adopted. The research builds upon previous findings that argued a level of best fit for the three innovation diffusion concepts of cohesion, structural equivalence and thresholds. That level of best fit is analysed here using empirical data from the UK construction industry. This analysis allows an understanding of how the relative importance of these concepts' actually varies within the stages of the innovation diffusion process. The conclusion that the level of relevance fluctuates in relation to the stages of the diffusion process is a new development in the field.

Technological innovation in the context of PPPs: incentives, opportunities and actions

From a construction perspective, Public-Private Partnership projects (PPPs) are often credited as providing real incentives for the actors involved as well as a business environment that is conducive to innovation and improved practices. The validity of four common rhetorical arguments used to promote the PPP procurement route is explored: collaborative working, design freedom, long-term commitment and risk transfer. Particular interest is given to the extent to which espoused intentions correlate with experienced realities in allowing actors involved in the design and construction phases to be presented with, and able to exploit, opportunities for technological innovation. It is argued that there is reason to be cautious in fully accepting the purported benefits of the PPP framework and that the arguments often presented need to be revised. Alternative interpretations are provided.

Tales of the expected: investigating the rhetorical strategies of innovation champions

Innovation continues to be high on the agenda in construction. It is widely considered to be an essential prerequisite of improved performance both for the sector at large and for individual firms. Success stories dominate the parts of the academic literature that rely heavily on the recollections of key individuals. A complementary interpretation focuses on the way innovation champions in hindsight interpret, justify and legitimize the diffusion of innovations. Emphasis is put on the temporal dimension of interpretation and how this links to rhetorical strategies and impression management tactics. Rhetorical theories are drawn upon to analyse the accounts given by innovation champions in seven facilities management organizations. In particular, the three persuasive appeals in classic rhetoric are used to highlight the rhetorical justifications mobilized in the descriptions of what took place. The findings demonstrate the usefulness of rhetorical theories in complementing studies of innovation.

Regulation and innovation: Rethinking 'inclusive' housing design

The Lifetime Homes (LTH) concept initiated in 1989 by the Helen Hamlyn Trust, and subsequently promoted by the Joseph Rowntree Foundation, emerged at a point when there was growing awareness of the decline of both private and public sector housing quality, especially in relation to floorspace standards (Karn & Sheridan, 1994). LTH were intended to offset the concerns of first, the house buying public of the appearance and affordability of homes suitable for successive generations, second, the private house building industry of the cost and marketability of incorporating 'inclusive' design features, and third, Registered Social Landlords (RSLs), who had to balance cost constraints with addressing the needs of a growing number of households with older and/or disabled people. Approved Document Part M of the building regulations was extended in 1999, from public buildings to private dwellings, and currently requires that all new housing meet minimal 'visitability' criteria. Indeed, although the signs are that Part M will be incrementally extended to comprise LTH principles, the paper argues that in their existing form they are insufficient to act as a key component of the government's 'new agenda for British housing'. This paper therefore explores how they might usefully be expanded from an approach, largely based on compromise, to one that inspires innovative, flexible and inclusive house forms, which also challenge design conventions.
