The study used Mixed Method Research Design to help Member States in planning the activities required in all phases in a new nuclear power program, and developing the competencies and capabilities required to start such activities; also, it aimed to address the competency gaps of the DOE NEPIO based on the IAEA Milestone Approach; the interventions taken by the DOE to address those competency gaps, and the respondents’ feedback about the gaps such as lessons learned as a mechanism for promoting and encouraging experience sharing culture. Data and feedback for organizational effectiveness are analyzed using Quantitative Gap and Normal Probability Analysis; Descriptive with Hierarchical Cluster Analysis; and Quantitative Content Analysis. The Competency Gap based on this representation is present and that capacity building of Human Resource Development and Outsourcing are addressing it. The leadership part showed the importance of this study, which follows INIR report findings, where the application of the Knowledge Management Method of After-Action Review is needed to engage stakeholders. The highest priority for countries embarking on nuclear work in progress is safety. The lessons on safety perspectives as shown in the responses were lacking, but in the Knowledge Management system in this context, efficiency is measured by lessons documented over lessons used, and where it is essential of high reliability, nature, significance, and costeffectiveness. Underlining the importance of the competency framework toward universalization and full implementation, leaders are conscious of their responsibility and take steps visibly, considering national conditions while protecting sensitive information, and contribute to strengthening and building confidence in the effectiveness of national nuclear infrastructure. In addition, it urgently needed national and international technical capabilities, relationships, and trust, where “capacities” must also be developed before a crisis through frequent engagement, including exercises such as competency assessment. Communicate more generously the results of missions that does not compromise the confidentiality of sensitive information, while assessing the reliability of the IAEA capacity-building models to the protection of the Filipino people, their property, the society, and the environment.
