Abstract

Briefing in a project delivery context is one of the most critical factors in the project success. It defines client requirements, translates these needs into design criteria and generates a design concept. A lack of briefing clarity is one of the main causes of design changes and may lead to project cost and time overruns. This research aims to assess the brief clarity and its influence on project cost and duration.Design/methodology/approachThis research created the PDRI-SD technique by utilising a system dynamic (SD) approach and project definition rating index (PDRI) tool to model the complex system of project briefing and associated variables. Stock and flow diagrams of the main subsystems including the briefing, the detailed design and the construction process, were developed to assess the influence of brief clarity on project cost and time. The PDRI was adopted to measure the briefing clarity and apply in the model. PDRI-SD was then tested in Australian building refurbishment projects to assess the model's effectiveness.FindingsThe simulation results indicated that a minor reduction of the lack of clarity throughout the initial briefing process could significantly mitigate unpredicted delay and cost overruns during the detailed design and the construction stage.Originality/valueThis research contributed to the existing body of knowledge by developing an effective technique to measure the impact of lack of brief clarity on project cost and time performance. PDRI-SD can also aid project clients to predict the influence of the initial defined brief on the detailed design and construction process using the historical data of similar previous projects. It provides clients with feedback, indicating whether the brief meets project requirements or whether parts of the project brief require more clarification/rectification before the project handover to the builders.
