'Stakeholder Interactions in Procurement and Management of Building Services

Abstract: Building Services (BS) can greatly benefit from blockchain in addressing issues related to Procurement and Management (P&M), such as lack of trust, transparency, and stakeholder collaboration. Identifying current processes and stakeholders in the P&M of BS is crucial before implementing blockchain technology. This research aims to develop a conceptual framework for the stakeholders and processes within the P&M of BS. Initially, a critical literature review was conducted to identify these stakeholders and their involvement. Based on the findings from the literature review, a conceptual framework and “stakeholder-process” diagrams were developed. To refine the “stakeholder-process” diagrams, 19 expert interviews were conducted with professionals directly involved in the P&M of BS, each with over five years of experience. A use case diagram was then modelled to create a prototype application of blockchain for the P&M of BS. The developed conceptual framework will offer a comprehensive overview of the stakeholders and the processes involved in the P&M of BS. This framework can be utilised to create any real-time applications related to BS. As a future step, the use case diagram can be used to develop Data Flow Diagrams (DFDs) and Entity Relationship Diagrams (ERDs) for the prototype development of blockchain in P&M.
