Corporate accreditation through the Association for Project Management (APM) provides a framework for competencies, qualifications, continuing professional development, and accountability for project managers. Network Rail has undertaken an accreditation process through APM to develop its project, program, and portfolio management (P3M) capabilities. This involves supporting the five dimensions of professionalism - breadth, depth, achievement, commitment, and accountability. Network Rail's accreditation helps retain talent, demonstrate competencies to stakeholders, and align with good practice as the company works to more efficiently deliver its capital program.
