"Value stream mapping (VSM) refers to the activity of developing a visual representation of the flow of processes, from start to finish, involved in delivering a desired outcome, service, or product (a “value stream”) that is valued by customers. In the context of government, a value stream could be the process of conducting an audit, completing a procurement, or hiring new agency staff. VSM can increase understanding of actual decision-making processes and identify sources of non-value-added time (e.g., documents waiting to be reviewed). The typical products of a 2-5 day VSM workshop are a map of the “current state” of targeted processes and a “future state” map of the desired process flow and an associated implementation plan for future process improvement activities."

The VSM diagram example "Value stream map parts" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Value Stream Mapping solution from the Quality area of ConceptDraw Solution Park.

The vector stencils library "UML interaction overview diagrams" contains 13 symbols for the ConceptDraw PRO diagramming and vector drawing software.
"Interaction Overview Diagram is one of the fourteen types of diagrams of the Unified Modeling Language (UML), which can picture a control flow with nodes that can contain interaction diagrams.
The interaction overview diagram is similar to the activity diagram, in that both visualize a sequence of activities. The difference is that, for an interaction overview, each individual activity is pictured as a frame which can contain a nested interaction diagrams." [Interaction overview diagram. Wikipedia]
"Interaction diagrams.
Interaction diagrams, a subset of behavior diagrams, emphasize the flow of control and data among the things in the system being modeled:
(1) Communication diagram: shows the interactions between objects or parts in terms of sequenced messages. They represent a combination of information taken from Class, Sequence, and Use Case Diagrams describing both the static structure and dynamic behavior of a system.
(2) Interaction overview diagram: provides an overview in which the nodes represent interaction diagrams.
(3) Sequence diagram: shows how objects communicate with each other in terms of a sequence of messages. Also indicates the lifespans of objects relative to those messages.
(4) Timing diagrams: a specific type of interaction diagram where the focus is on timing constraints." [Unified Modeling Language. Wikipedia]
The example "Design elements - UML interaction overview diagrams" is included in the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.
