Abstract In organisations formed by individuals who come together to achieve a certain purpose, communication, which provides the information exchange process, is one of the most important conditions for the organisation to survive and work effectively. In this direction, organisational communication refers to the verbal and written message exchanges that the organisation establishes within and outside the organisation. The purpose of organisational communication is to direct the behaviours of the employees of the organisation in line with the aims and objectives of the organisation and to coordinate the production relations. Problems arise in organisations and groups where organisational communication is incomplete or incomplete. This is because lack of communication creates a communication gap between staff-manager and staff-personnel within the organisation. This situation is reflected on the effectiveness of the organisation and many problems such as loss of motivation and lack of trust arise and affect the effective operation of the organisation and service delivery. This communication problem has also manifested itself in public institutions and has been constantly expressed. In this study, the reflections of the communication problem on the public sector are discussed in detail and as a result of the developing world order, accountability and transparency principles, communication and giving more importance to citizens' knowledge and effective participation are discussed in detail. Firstly, the general organisational communication problems experienced in the public sector and their consequences are discussed, and then the solution suggestions for minimising these problems are mentioned. In the last part of the study, the e-government application, which is presented as a tool to solve the communication problem in the public sector and which is based on ensuring the effective participation of citizens and informing them, is briefly evaluated.
