The flowchart shows two separate dashed boundary sections containing multiple rounded and rectangular boxes connected by arrows. In the upper dashed boundary, on the left is a rounded box titled “Data collection”. Inside is the text “Sources (19 official websites)” followed by bullet points: “Government-funded research centres (A R C, C R C, H I A);” “Federal departments: D I S R, D I T R D C S A, the Treasury, and Federal Parliament;” “State portals: V I C, N S W, Q L D, W A, S A, N T, N A T, T A S; and” “Relevant agencies: Housing Australia, A B C B; Standards Australia; Prefab A U S”. To the right within the same dashed boundary is a rounded box titled “Screening and eligibility checking”. Inside is the heading “Inclusion:” followed by: “1) Policy types: Regulations; guidelines; plans; decisions; opinions; grants; trial measures; circulars; notices (independently or jointly issued)”. “2) Timeframe: 2015 to June 2025”. “3) Keywords: ‘prefabricated’, ‘prefabrication’, ‘prefabricated construction’, ‘prefabricated housing’, ‘transportable home’, ‘kit home’, ‘modular’, ‘modular house’, ‘modular construction’, ‘manufactured house’, ‘off-site construction’, ‘Modern Method of Construction (M M C)’, ‘M M C’”. Below is “Exclusion:” with bullet points: “Measures that lacked direct policy relevance”, “originated from non-governmental sources”, and “constituted minor administrative updates without substantive policy change”. A downward arrow leads to an oval labeled “Dataset: 87 policy measures identified across jurisdictions and agencies for quantitative slash qualitative analysis”. In the lower dashed boundary is a section titled “Content analysis”. Inside are two side-by-side boxes. The left box is titled “Coding and Classification” with bullet points: “Historical review” and “Coded analysis of five categories:” followed by “Incentive”, “Initiatives”, “Law and Regulations”, “Guidance”, and “Standards”. The right box is titled “Longitudinal and cross-jurisdictional analysis” with bullet points: “Historical evolution of prefabrication-related policies in a longitudinal study”, “Statistical Summary of Prefabrication-Related Policy by Categories”, and “Comparative Focus and Differences by Jurisdiction”. Arrows connect from the “Data collection” box to the “Screening and eligibility checking” box, then downward to the dataset oval, and then downward to the “Content analysis” section in the second dashed boundary. Also, an arrow from “Coding and Classification” points to “Longitudinal and cross-jurisdictional analysis” box.The research framework
