    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

    The first structured method for documenting process flow, e.g., in flow shop scheduling, the flow process chart, was introduced by Frank and Lillian Gilbreth to members of ASME in 1921 as the presentation "Process Charts, First Steps in Finding the One Best Way to Do Work". [2]

  9. Data-flow diagram - Wikipedia

    en.wikipedia.org/wiki/Data-flow_diagram

    The DFD notation draws on graph theory, originally used in operational research to model workflow in organizations, and in computer science to model the flow of inputs and outputs across computations. [2] [3] DFD originated from the structured analysis and design technique methodology in the middle of the 1970s. [3]
