“Quality Breakdown Structure per la Costruzione” “Quality Breakdown Structure for Construction”

The measurement of the performance of a construction project is a basic issue of Construction Management, and it is based upon project – related indexes known as Key Performance Indicators (KPIs). Key Performance Indicators are project measurements that substantiate the health of the project and can be used to predict the future performance of the construction project. The measurement of the performance of a construction project is usually based upon different metrics relating to time, cost, resources, quality and project specific indicators. But while for time, cost and resource usage it is simple to transfer project performance into meaningful indexes, relating to work packages or to the entire project, it is difficult to define and evaluate quality – related issues and metrics for construction project control. The way forward to implement quality related metrics is the definition of a Quality Breakdown Structure (QBS) of the construction project. The Quality Breakdown Structure is the basic tool to consider the various elements of quality like product and process quality and value to the customer, to put them into relationship and to evaluate their relative weight in the construction project and its sub-processes. Quality related performance indicators can be loaded to the construction project scheduling model, with the goal of showing to Project Manager and to Stakehoders the achieved versus planned quality in the project status. This could be a new important issue to improve construction project monitoring and controlling process, with the aim of the timely implementation of corrective actions to achieve project objectives.
