(15)To manage the rapid advancement in ICT environments, financial entities referred to in Title II of this Regulation should implement robust ICT project management policies and procedures to maintain data availability, authenticity, integrity, and confidentiality. Those ICT project management policies and procedures should identify the elements that are necessary to successfully manage ICT projects, including changes to, acquisitions of, the maintenance of, and developments of the financial entity’s ICT systems, regardless of the ICT project management methodology chosen by the financial entity. In the context of those policies and procedures, financial entities should adopt testing practices and methods that suit their needs, while adhering to a risk-based approach and ensuring that a secure, reliable, and resilient ICT environment is maintained. To guarantee the secure implementation of an ICT project, financial entities should ensure that staff from specific business sectors or roles influenced or impacted by that ICT project can provide the necessary information and expertise. To ensure effective oversight, reports on ICT projects, in particular about projects that affect critical or important functions and about their associated risks, should be submitted to the management body. Financial entities should tailor the frequency and details of the systematic and ongoing reviews and reports to the importance and the size of the ICT projects concerned.
