How is the start of IEM indicated on the Quarterly board?

The correct choice highlights that the start of Integrated Enterprise Management (IEM) is indicated on the Quarterly board by a vertical red line placed in front of the first week in IEM status, which is also preceded by either an 'I' or a 'II'. This notation is essential as it visually marks the commencement of IEM on the board, making it easy for supervisors and team members to identify when this phase begins. The inclusion of 'I' or 'II' serves as a classification or categorization, providing additional context about the type or stage of IEM being represented. This ensures clarity in communication regarding deadlines or phases, enhancing productivity and organization.

In contrast, options that describe the placement of the red line after the last week in IEM status would not effectively mark the start of IEM, as they misrepresent the necessary visual cue that indicates the beginning of this important management phase.
