This research investigates the impact of discipline and disciplinary procedures on effective service delivery in the Nigerian public service. It examines the existing disciplinary framework, its implementation challenges, and the perceived effectiveness of disciplinary actions in improving public service performance. The study utilized the bureaucratic theory as its theoretical framework in understanding discipline and disciplinary procedures and effective service delivery in Nigeria's public service. Qualitative methods of data collection and content analysis procedures were utilised. Findings reveal significant gaps in the implementation of disciplinary measures, including weak enforcement, lack of transparency, and inadequate training for disciplinary committees. These shortcomings contribute to low morale, decreased productivity, and ultimately hinder effective service delivery. The research concludes with recommendations for improving disciplinary procedures, such as strengthening the independent oversight of disciplinary proceedings, enhancing transparency and accountability, and providing comprehensive training programs for all stakeholders involved in the disciplinary process.
