The Product Platform Rulebook is an open-access guide, developed by the Construction Innovation Hub and industry leaders, for various stakeholders within the supply chain to develop and deploy Product Platforms. The Rulebook aims to enable and promote the adoption of Product Platform approaches by providing guidance, tools, and a common framework for the industry. The construction industry needs disruption, which the innovators and early adopters have initiated over the last few decades with the adoption of Modern Methods of Construction. But we now need guidance to build confidence in the approach for the majority to follow. A Product Platform is often referred to as a ‘Kit of Parts’ which is a group of common and repeatable assets that can be configured and combined with interoperable components to deliver a range of distinct projects.
