CAUSE AND EFFECT DIAGRAM. Also calledfishbone diagrams they show hypothesizedrelationships between potential causes andproblem under study.. Once the C & E diagramis constructed the analysis would proceed tofind out which of the potential causes were in
fact contributing to the problem

CONTROL CHARTS. These are time sequencedcharts showing plotted values of a statisticincluding a centre line average and one ormore control limits. It is used to ensure thatchanges introduced are in statistical control
FLOW CHARTS. Give us a logical flow of anactivity or process. Can be applied whilechecking the quality

PARETO CHART. These are named afterVilfredo Pareto who is credited for theorybehind Pareto Chart, also referred as 80:20rule. This rule as applied to quality says that asmall number of causes (20 %)create themajority of problems. Pareto theorized that
you get the most benefit by spending themajority of time fixing the most importantproblems.

RUN CHARTS. Run charts are used to showvariations in trends in the process over time.They are similar to control charts, thoughwithout a displayed limit. Some otherinformation
Common causes of variations come about as a
result of circumstances or situations that arerelatively common the process you are using andeasily controllable at the operational level

INSPECTION. Inspection typically involvephysically looking at, measuring, or testingresults to determine whether they conform to
the requirements or quality standards.Inspection will tell you where problems existsand gives you the opportunities to correctthem, thus leading to quality improvements.
Inspection might occur after thr final product isproduced or at intervals during the developmentof the product to examine individual components
