1. THE 7 QUALITY TOOLS

   • FLOWCHART
     • A flowchart is a graphical representation of a process that shows the stages and activities in sequential order
   • VERIFICATION SHEET
     • A check sheet is a tool for systematically collecting data and recording the frequency of events or characteristics.
   • HISTOGRAM
     • A histogram is a bar graph that shows the distribution of numerical data.
   • ISHIKAWA
     • An Ishikawa diagram is used to identify and visualize the possible causes of a problem, organizing them into categories.
   • CONTROL CHART
     • control chart is used to monitor and control a process over time, identifying significant variations
   • PARETO DIAGRAM
     • A Pareto chart is a graphical representation that shows the relative importance of various problems or causes, highlighting the most significant ones.

2. demin cicle

   • Plan
     • In this initial phase, you identify a problem, need, or opportunity for improvement. This involves setting clear objectives and goals.
   • Do
     • Once the plan is established, you put it into action. This involves implementing the planned changes or improvements on a small scale, often as a pilot project
   • check
     • In this stage, you evaluate and analyze the results obtained during the "Do" phase. Compare the actual results with the expected outcomes and goals set in the planning phase.
   • act
     • Based on the analysis in the "Check" phase, make informed decisions about what to do next. If the results meet or exceed expectations, consider implementing the changes on a larger scale. - If the results are not as expected, use the knowledge gained during the PDCA cycle to make necessary adjustments to the plan and then return to the "Do" phase to try again.

3. poka yoke

   • what is a poka yoke
     • Poka-Yoke is a tool from Japan that stands for "error proof". What is sought with this way of designing processes is to eliminate or avoid mistakes, whether of human origin or automated. This system can also be implemented to facilitate error detection
   • A design
     • that only allows the parts to be connected in the right way. If you try to fit it upside down or in the wrong place, the pieces will not fit.
   • Color codes
     • For example, in computer connectors, each type of connection has a different color to facilitate its assembly.
   • Arrows and indications
     • of the type "a-> <-a","b-> <-b"... to indicate where each piece is fitted and what its orientation is.
