The publishing industry has dramatically changed in the last two decades. Turning towards electronic publishing, (EP) has required crucial developments, one of which is to equip specialists with a variety of competencies for performing the technical and managerial tasks of (EP). To date, no study has comprehensively investigated the requisite competencies for these tasks and the sources of learning and qualifying EP professional, especially in Egypt and the Arab World. This paper identifies professional competencies for each task through a proposed matrix. To design this matrix, several related studies have been consulted to collect the defined competencies. Afterwards, a survey has been designed and distributed to explore the application of these competencies in the real EP practices. Finally, a Focus Group has been designed to assign the required competencies for each surveyed task. The results showed that the most practiced tasks are: EP planning, and acquisition. On the other hand, and in order to acquire knowledge and experience, specialists often rely on direct communication with experts and their colleagues at work and also design professional training courses. User support and communication are the most required competencies for (EP) tasks. Further, disciplinary knowledge category represents the highest weighted category among three categories of competencies. The matrix could be applied as a competence-based professional formal education and job training framework, which would help students and trainees meet the fundamental requirements of the labor market.
