**the**

**7 QC Tools for Process Improvement.**

→ A flow chart is a visual representation tool for a process, therefore, the process easily illustrates the Internal and external operational boundaries.

→ “A diagram which represents a meaningful relationship between an effect and its causes are called the Cause & Effect Diagram."

→ Another name of Cause and effect diagram is a Fishbone Diagram or Ishikawa Diagram.

→ Cause and Effect Diagram (Fishbone diagram or Ishikawa Diagram) is a part of

→ It guides concrete action and tracks the potential causes during an investigation the effort to determine whether the item significantly contributes to the problem or not.

→ "Check Sheet

→ The purpose of a checklist is to summarize the data and a tally count of event occurrences.

→ A check sheet counts the number of occurrences of an event, such as defects or non-conformance.

→ Hence the Check Sheet is a "tally sheet " of

→ In many cases, a checklist will summarize countable data related to certain types of defects and will provide a rough graphical representation of wherein a part of the process, defects occurred.

→ "Check Sheet**is a structured, prepared form for collecting and analyzing data."**→ The purpose of a checklist is to summarize the data and a tally count of event occurrences.

→ A check sheet counts the number of occurrences of an event, such as defects or non-conformance.

→ Hence the Check Sheet is a "tally sheet " of

**the****7 QC Tools for Process Improvement.**→ In many cases, a checklist will summarize countable data related to certain types of defects and will provide a rough graphical representation of wherein a part of the process, defects occurred.

→ “Histogram

**is a type of bar chart representing the frequency distribution of the data from a process.”**
→ The histogram is the best Frequency distribution tool of

→ A histogram is a pictorial representation of a set of data.

→ "Pareto chart is a bar graph arranged in descending order of height from left to right”

**the 7 QC Tools for Process Improvement.**→ A histogram is a pictorial representation of a set of data.

####
➤ [5] **7 QC Tools **Pareto Chart :

→ "Pareto chart is a bar graph arranged in descending order of height from left to right”
→ “Pareto chart is a diagram that shows the order of the largest number of occurrences by item or by classes and the cumulative sum total.”

→ Pareto Chart communicates the principle of 80:20, therefore the Pareto Chart is an 80:20 analysis chart.

→ The Pareto Chart also gives us information about Vital few from Trivial many, Hence, Pareto chart is "Vital few from Trivial many tools" of the 7 QC tools for Process Improvement.

→ It states that 80% of an effect comes from 20% of the causes.

→ “Scatter Diagram is used to study and identify the possible relationship between two variables”.
→ Scatter diagram is the best validation tool of

####
➤ [7]

→ “Control chart is a type of run chart used for studying the process variation over time."

→ Most importantly, the control chart is a time series plot that is used to monitor a process over time.

→ It is a plot of a process characteristic, usually through time with statistically determined limits.

→ When used for process monitoring, it helps the user to determine the appropriate type of action to take on the process depending on a degree of variation in the process.

→ With comparing above all tool Control Chart is the best process forecasting tool of
