Based on the two statements provided:
1. Coaching timelines are not grade dependent and are not specifically defined by the Marine Corps guidebook for coaching. Coaching as a leadership tool can be applied across different levels of expertise and is not limited to a specific guideline outlined by the Marine Corps.
2. The statement "Coaching is a sustained daily effort focused on development" better describes the timeline associated with coaching as a leadership tool. This means that coaching is an ongoing process that occurs regularly to support the growth and improvement of individuals or teams. It emphasizes continuous support and guidance to facilitate progress and development.
Therefore, the second statement aligns more accurately with the concept of coaching as a sustained and ongoing effort for development within a leadership context.
