Enhanced model of the innovation-decision process, for modular-technological-process innovations in construction

Research output: Contribution to journalArticlepeer-review

Abstract

Purpose
The purpose of this study is to establish an enhanced model of the innovation-decision process (IDP), specifically for construction. As context, innovation diffusion theory (IDT) is concerned with explaining how some innovations successfully stick whilst others fail to propagate. Because theoretical models provide abstracted representations of systems/phenomena, established IDT models can help decision-making units with innovation-related sense-marking and problem-solving. However, these occasionally fail or require enhancement to represent phenomena more successfully. This is apparent whenever middle-range theory seems ill-fitted to the complexity of construction.

Design/methodology/approach
Qualitative research via 13 semi-structured interviews occurred, with participants recruited via convenience and purposive sampling strategies. The study forms part of a broader mixed-method study (n = 246) informed by a research philosophy of pragmatism, investigating the applicability of classic IDT to the adoption of four-dimensional (4D) building information modelling (4D BIM) by the UK construction sector.

Findings
This diffusion study resulted in the adaptation of an existing IDP model, ensuring a better contextual fit. Classified more specifically as a modular-technological-process innovation, 4D BIM with its potential to provide construction planning improvements is used as a vehicle to show why, for construction, an existing model required theoretical extensions involving additional stages, decision-action points and outcomes.

Research limitations/implications
This model can assist construction industry actors with future adoption/rejection decisions around modular-technological-process innovations. It also aids the understanding of scholars and researchers, through its various enhancements and by reinforcing the importance of existing diffusion concepts of compatibility and trialability, for these innovation types.

Originality/value
An enhanced model of the IDP, specifically for construction, is established. This construction-centric contribution to IDT will be of interest to construction scholars and to practitioners.
