this issue. QVSM is a procedure model, complementing
classical Value Stream Mapping with specific quality related
elements to systematically visualize, analyze and improve
quality issues within a process chain. In addition to the
production processes and flow of materials, present quality
defects, quality inspections and quality control loops are
considered. Based on this, the status of the quality control
along the process chain is evaluated in terms of key indicators
with regard to quality and quality-related costs.
Similarly to conventional VSM, in the concept of QVSM
the term “value” is defined as the opposite of waste. However,
due to the special focus on quality control in QVSM, the
reduction of defects as a type of waste and the identification
of suitable measures for this are emphasized.
The presented method of QVSM consists of four phases:
preparation, quality value stream analysis (QVSA), quality
value stream design (QVSD) and implementation. In the
following, these phases are elucidated in detail
