It can be seen as a chain of scripts that provide the following additional benefits:
   * ''Operation grouping'': Operations are grouped together into stages (also known as gates or quality gates) that introduce a structure into a process and clearly define a rule – if one stage fails, no further stages are executed.   * ''Operation grouping'': Operations are grouped together into stages (also known as gates or quality gates) that introduce a structure into a process and clearly define a rule – if one stage fails, no further stages are executed.
   * ''Visibility'': All aspects of a process are visualized, which helps in quick failure analysis and promotes team collaboration.   * ''Visibility'': All aspects of a process are visualized, which helps in quick failure analysis and promotes team collaboration.

 The pipeline has no special requirements in terms of environment, and it executes three steps inside two stages. When we click on __Build Now__, we should see a visual representation: The pipeline has no special requirements in terms of environment, and it executes three steps inside two stages.
