Final answer:
The Chain of Command Communication Model is deficient in terms of Inefficiency, lacking Flexibility, and overemphasizing Simplicity, which can lead to productivity and adaptability issues in modern organizations.
Step-by-step explanation:
When discussing the 3 Deficiencies of the Chain of Command Communication Model (IFS), one must consider its relevance in the context of modern organizations. The traditional chain of command structure has been noted for its Inefficiency in the information age, where adherence to rigid protocols can hinder productivity. Flexibility is another area where this model falls short. In dynamic and rapidly changing environments, the inability to adapt quickly is a serious drawback. Lastly, while the model may provide some level of Simplicity in decision-making, it often overlooks the subtleties and complexities of organizational operations, leading to oversimplification and potential mismanagement.
