Rich picture diagram is a visual representation of a situation or a complex system, incorporating texts, symbols, and icons to illustrate various elements and their interrelationships. A simplified version of this diagram is commonly referred to as a mind map.

This diagram is particularly useful when improvements are needed within a system. As the saying goes, “a picture is worth a thousand words,” the rich picture diagram provides comprehensive overview of a situation or system. It helps identify overlooked processes and minor yet significant connections within the system. By visualizing these relationships, the diagram ensures that no critical elements are missed, ultimately facilitating a more thorough understanding and enhancement of the system.

Steps in creating a rich picture diagram:

  1. Gather information, by collecting relevant data and insights about the system or situation.
  2. Identify key elements, by determining the main entities and components involved.
  3. Establish relationships, by illustrating connections and interactions between elements.
  4. Add details, by including annotations, symbols, and visuals to enhance clarity.
  5. Review and refine, by assessing the diagram for completeness and make necessary adjustments.

An example on the application of rich picture diagram for improvements in a system is as follow:

Figure 1: Rich Picture Diagram of the Traditional Parking System

Figure 1 shows a traditional parking system in which the process follows a straightforward sequence. Upon arrival, the vehicle will take a parking ticket. Next, the vehicle will park in the available parking lot. When leaving the parking lot, the driver will scan the ticket and complete the payment for the parking fare.

Figure 2 presents an improved parking system incorporating new features, such as parking reservations, membership options, and parking detectors. These enhancements provide drivers with greater flexibility when parking.

Figure 2: Rich Picture Diagram of an Improved Parking System

Upon arrival, drivers have the choice of either taking the parking ticker or scan a membership card. Those who uses the traditional ticket system will follow the same process as figure 1. However, members who scanned the membership card will scan once more when existing and will not be required to pay the parking fare. Additionally, members can reserve a parking slot in advance as well.

The system also introduces parking detectors to improve efficiency. Available slots are marked in green, occupied slots in red, and reserved slots in blue. Furthermore, a display screen will also be used to show the number of available spaces, making it easier for drivers to find parking quickly.
