As part of a Visual Factory plan __________ cards are created and utilized to identify areas in need of cleaning and organization.

Kanban is a visual signaling system central to Lean and the Visual Factory concept. Its primary function is to trigger an action. While commonly used to manage inventory and production flow (e.g., signaling the need to produce more parts), its principles are adaptable. In the context of workplace organization (5S), a "housekeeping Kanban" or "5S Kanban" can be used. These cards act as visual cues to signal that a specific area requires cleaning, supplies need restocking, or an organizational task is due. This makes Kanban a fitting tool for visually identifying and managing cleaning and organization needs.

B. Kaizen: Kaizen is a philosophy of continuous improvement. Kaizen cards are used for submitting suggestions for improvements, which is different from a direct signal that a scheduled or required task is due.
C. Poke-Yoke: This is a mistake-proofing technique or device designed into a process to prevent human errors. It is not a card-based system for identifying workplace organization needs.
D. WhoSai: This is not a recognized term or tool within the Lean Six Sigma or Visual Factory framework and serves as a distractor.

1. Locher, D. (2011). Lean Office and Service Simplified: The Definitive How-To Guide. Productivity Press. In Chapter 11, "Visual Management," the author discusses extending visual controls like Kanban beyond production, stating, "Kanban can be used to signal the need for any type of material or information" (p. 127). This general principle supports its application for signaling cleaning tasks.

2. Manos, A. (2006). The benefits of a 5S program. Quality Progress, 39(5), 80. This article discusses the visual nature of 5S. While it focuses on Red Tags for sorting, the underlying principle of using visual devices to signal a need for action is consistent with the broader application of Kanban principles for sustaining 5S efforts.

3. Ohio State University, Fisher College of Business. (n.d.). Lean Tools: Kanban. In course materials for Operations Management, Kanban is defined as a signal that authorizes action. The materials emphasize its role as a visual communication device in a pull system, a concept that can be applied to trigger maintenance or cleaning activities when a certain condition (e.g., a dirty area) is met. (Reference to general university courseware principles on Lean).
