abstract={This paper has explored Target Value Delivery (TVD) in the specific context of a single-entity design-build organisation. It does not attempt to recommend one ideal form of TVD but to discuss the possibility of adapting it to various business environments and cultural scenes. TVD stood out as a candidate for deeper consideration when prospecting innovation opportunities in value delivery by simultaneously tacking procurement methods and internal process reforms. Design Science Research has been selected as the research approach. The artefact is a modification of the TVD reference model to leverage the potential of general contractors holding full-fledged design departments - a different structure from cases reported overseas leaning toward three-party Integrated Project Delivery (IPD). The experimental design of a tentative combined model with existing practices was grounded on the iteration with and review of multidisciplinary engineers over the last 1.5 years. The conclusion was that abstract concepts entangled in TVD could be challenging to convert into executable processes when over-relying on behaviour change by parties with different interests and priorities. Rather, systematisations such as devising applications that somewhat forcibly yet friendly guide TVD workflow could be potentially effective. The next step is instantiating the mechanisms contained in the customised model. },
