About Lecture Series 6: Organisational Communication

This lecture blog series is designed for students in tertiary institutions studying Organisational Communication. Each chapter is presented as a self-contained lecture that can be read independently or followed sequentially as a complete course, covering every major topic from foundational communication theory to practical strategies for improving communication effectiveness in real Nigerian and global organisations.

Every chapter includes detailed concept explanations with key concept boxes, real-world Nigerian workplace examples, references to contemporary academic sources (2020 onwards), structured time allocations for reading and study, and examination practice questions with mark allocations to help students prepare thoroughly for their assessments.

The series adopts a mixed citation approach — key theories and models are cited with full Harvard-format academic references, while explanations and examples are presented in clear, accessible prose suitable for tertiary-level study and professional development.
