Mega/Major projects should not need to develop a bespoke common data platform each time. Software developers like UniPhi (www.uniphi-software.com) have been providing such cloud-based (SaaS) solutions for many years and are well placed to enable the elusive Single Source of Truth for Integrated Delivery Teams having numerous suppliers and stakeholders across the enterprise. UniPhi's solid integration options with other project systems, and rapid configuration and implementation, is the key to providing a data hub covering all project information requirements, dashboards etc.
