Correct option is B
Hollow talk, Debilitating fear, and Mindless reliance are primary organizational barriers to successful strategy implementation and long-term sustainability. These are commonly identified as the "silent killers" of effective management and change efforts (as per Beer & Eisenstat’s work).
Hollow talk (A): Refers to when leaders talk about change but do not take meaningful action. This destroys credibility and followership.
Debilitating fear (B): Prevents honest communication, feedback, and risk-taking, all of which are essential for implementation.
Mindless reliance (D): Happens when managers blindly follow external practices or systems without adapting them to their context, leading to ineffective decisions.
Although complex measurement systems (C) can be a challenge, they are not consistently identified as a core cause in literature compared to A, B, and D. Similarly, constructive internal competition (E) can be a positive force when managed well.
Information Booster:
For strategy and change to be effectively implemented, management must bridge the gap between planning and action. Factors like Hollow Talk signal a lack of authenticity and misalignment between strategy and behavior. Debilitating Fear undermines psychological safety, making employees reluctant to share problems or innovate. Mindless Reliance on best practices removes critical thinking and custom-fit solutions. Together, these elements erode trust, stall progress, and compromise sustainability. Managers must create a culture of clarity, openness, and context-driven execution to succeed.
Additional Knowledge:
C. Complex measurement systems:
While they can complicate execution, they are not inherently a barrier unless misaligned or excessively bureaucratic. With the right design, they aid transparency and accountability.
E. Constructive internal competition:
This does not prevent implementation. In fact, when managed effectively, it encourages innovation, drive, and performance. The key lies in maintaining fairness and aligning it with organizational goals.
