Which of the following is considered a necessary resource for achieving success in a task?

To determine the necessary resources for achieving success in a task, it's crucial to recognize the key role that personnel plays. Personnel refers to the people involved in executing a task or project, and they are fundamental in driving tasks to completion. Their skills, knowledge, and ability to work together are vital for effective collaboration and problem-solving. Without the right personnel, even the best strategies or resources can fall short.

While time management skills and capital investment are important aspects of achieving success, they function more as supporting elements rather than essential resources. Time management skills help optimize the use of time, and capital investment provides financial backing, but neither can perform the task without the involvement of the personnel. Therefore, while they contribute to success, personnel is the foundation on which successful task execution is built.
