Which statement is true about the bar chart in project management?

The statement that drywall starts after the completion of doors and windows is true in the context of project management, especially in construction. In a typical construction project, the installation of doors and windows is usually part of the exterior finishing phase. Once these elements are secured and the structure is weather-tight, the interior work, such as drywall installation, can begin. This sequence is critical for ensuring that the interior environments are not exposed to moisture or other external elements, which could lead to damage or compromise the integrity of the drywall.

In terms of construction sequencing, different tasks must align with one another to ensure efficiency and safety in the project cycle. Proper scheduling helps avoid delays and ensures that each phase of construction is completed in the correct order. Understanding these dependencies is crucial for effective project management, as it allows managers to develop realistic timelines and allocate resources appropriately.
