Simplistic view of a PDCA cycle
Plan-Do-Check-Act > then Plan-Do-Check-Act > then Plan-Do-Check-Act... guess to you get the picture...

Act > Plan to improve

ISO 9001:2015 speak.
"...This International Standard employs the process approach, which incorporates the Plan-Do-Check-Act (PDCA) cycle and risk-based thinking.
The process approach enables an organisation to plan its processes and their interactions.
The PDCA cycle enables an organisation to ensure that its processes are adequately resourced and managed, and that opportunities for improvement are determined and acted on.
Risk-based thinking enables an organisation to determine the factors that could cause its processes and its quality management system to deviate from the planned results, to put in place preventive controls to minimize negative effects and to make maximum use of opportunities as they arise.
Note: The ISO 9001:2015 uses the methodology of the PDCA process throughout, however the PDCA cycle itself is not a requirement..."
