P1 PHCC is the central Project Health Control project supporting the development, maintenance, promotion and delivery of the PHC Service through the PHC Consortium. The project provides the strategic and operational foundation for introducing PHC Service to commercial organisations managing major projects, programmes and investment portfolios. It brings together the methods, systems, people, evidence, training, communications and delivery arrangements required to establish PHC as a practical project assurance capability. The primary proposition is the application of PHC Service to major commercial projects. Where a company is not yet ready to adopt PHC directly across its core portfolio, it may first commission a controlled pilot using a selected project from its CSR, ESG, sustainability or social-impact expenditure. This gives the company an opportunity to test the service, assess its value and experience the PHC approach before considering wider adoption. P1 PHCC therefore acts as the central project through which PHC Service is developed, demonstrated, governed and progressively introduced into commercial organisations.
