Which of the following is NOT a characteristic of effective organizations?

High employee concentration levels is not typically considered a characteristic of effective organizations. While focus and dedication among employees are important, an effective organization prioritizes a broader range of factors beyond just concentration. Characteristics such as adaptability to change reflect an organization's resilience and ability to navigate new challenges and opportunities effectively. Strong leadership is crucial, as it guides teams, builds trust, and fosters a positive work environment. Additionally, a focus on customer needs emphasizes the organization's commitment to meeting and exceeding customer expectations, which is fundamental for long-term success. Hence, while employee concentration can contribute to productivity, it does not capture the essential traits that define an effective organization.
