Effects of organizational behavior and internal communication on the productive performance of a public telecommunications company in Algeria
(Journal of Ecohumanism, 2026-01) Megheni, Zineb; Nedil, Lamia (ENSM)
In a context of accelerated technological change and increasing economic volatility, public telecommunications companies play a central role, influencing organizational culture and management practices. The telecommunications sector has also had to contend with, and continues to contend with, the repercussions of the Covid-19 pandemic, which has disrupted operational dynamics globally. Despite these challenges, the telecom sector is demonstrating resilience and continuing to evolve.In this context, our attention focused on employee productivity. We conducted a field survey of staff at telecommunications sales agencies in Algeria, with a focus on the Algiers region. The central objective was to analyze the relationship between two key dimensions: (i) employee behavior towards customers and (ii) internal communication among colleagues, in order to identify levers likely to improve company productivity.

(NeuroQuantology|, 2022-06-20) Nedil, Lamia (ENSM); Zerouti, Messaoud (ENSM); Khouatra, Salah Eddine
The digitalization of companies has accelerated with the COVID-19 crisis on a global scale, especially in
developing countries. Indeed, this digitization is supported by the rapid development of information and
communication technologies. In this context, our work essentially aims to propose the establishment of a
product manager process as a tool that allows the development of performance within a public company
in the Telecom sector in Algeria. To do this, we have focused on digital type products for the
implementation of an operational process (product manager process) which will help bring benefit to the
company. We first proposed the missions, the resources and the key competences. Second, we
administered a questionnaire using an interview guide to a sample size of ten (10) people, in order to
have a vision of our proposal for the process and its impact in the process. Improvement of the company's
performance.
The results of our study allowed us to have a vision of the need to set up this process so that managers
can make decisions and pursue product development, have good communication between stakeholders,
reduce risks, work in a team and finally get to know the customer through satisfaction surveys and
possibly the readjustment of digital product objectives.
The evaluation of algerians' attitude toward the use of the photovoltaic solar energy
(Jilin Daxue Xuebao (Gongxueban)/Journal of Jilin University (Engineering and Technology Edition, 2023-01) Boukhedimi, Chems Eddine; Messaoud, Zerouti (ENSM); Nedil, Lamia (ENSM)
The aim of this paper is to check the nexus between the demographic factors and the use of Photovoltaic solar energy between two Algerians cities Algiers and Tizi Ouzou. To check this issue, we collected 42 questionnaires online and face-to-face in order to measure the relationship between demographic factors and the willingness of respondents to install the PV solar kit. Moreover, in this paper, a novel method of consumer's segmentation in green Marketing is presented. Finally, a feasibility study was done to examine the profitability of the photovoltaic solar energy in a virtual house located in Algiers. The findings of the study indicate that the majority of respondents are aware of the use of renewable energies through results obtained after the use of the McNemar test. However, after checking our feasibility study, the main result shows that there is no profitability that belongs to the use of photovoltaic solar energy in houses for the residential sector. It should be remembered that the only demographic factor, which affects the PV instalment decision, is the city of living.

(Pegem Journal of Education and Instruction, 2025-09-27) Megheni, Zineb; Missoum, Mohammed Rafik Cherif; Nedil, Lamia
The communications sector in Algeria is
witnessing a qualitative leap, as confirmed by
the Information and Communications
Technology Development Index. IDI Issued by
the International Telecommunication Union
(2023)Despite the progress achieved by this
sector, it faces many challenges, as
telecommunications institutions work to
develop their businesses and improve the
quality of their services in light of the intense
competition and rapid technological
development. To achieve this, it has become
necessary for them to adopt new strategies that
enable them to achieve their goals efficiently.
Digital transformation is one of the most
important of these strategies, which affects the
entity of the institution as a whole, as it
contributes to ensuring the optimal utilization
of the institution’s resources, especially
internal ones (IT infrastructure, technical
capabilities, information systems).
