Deep Analysis Deep analysis Is a process involving coordination of knowledge Analysis Attitude and Intuition to solve real time problems at work place. www. qualimations. com
Deep Analysis The objectives of a Deep Analysis exercise are the following 1. Understanding the failure mode-its cause and effect 2. Achieve the return on investment by solving this problem. 3. Understanding the Process and system better. www. qualimations. com
Deep Analysis Identify the Need Think of your problems or concerns and try to answer the following questions 1. 2. 3. 4. Has the problem affected me? Is it a potential problem to come? What is the frequency of its occurrence? Can I quantify the problem? • Have I seen the problem? • Has the problem cost you significantly? 5. Is the time invested in solving the problem significant? 6. Should I avoid the problem? www. qualimations. com
Deep Analysis Identify the Need Do you know that seven out of 10 problems are not resolved. Instead they are avoided. Nature 1998 May edition www. qualimations. com
Deep Analysis Objective Have You Accepted that a problem really exist? 1. Is the problem going to be superficial? 2. Do you know the events that preceded this problem and the one that followed it? 3. Does solving this problem lead to other problems? www. qualimations. com
Deep Analysis Objective Getting deeper in the problem is more important than Solving the problem itself. Prof Psuda Toyota motors Ask the right question at the right time www. qualimations. com

Deep Analysis Definition What is a Problem? A problem is an opportunity when understood and gone deeper results in more knowledge and hence ensures continuous improvement or break troughs. Tolerance Expected Actual Gap Source Of failure A failure occurs when the actual results are not closer to the expected or the standards www. qualimations. com
Deep Analysis Society Problem Team Leader Customer Perspective Producer/Developer What is the Problem: Define the problem in at least two other ways www. qualimations. com
Deep Analysis Starting Where to start ? The ideal place to start the analysis would be the place of failure Itself. www. qualimations. com
Deep Analysis Ambience Observe the conditions of failure What day it was, the Day of week, the time and who reported the problem The Climate data, Ambience address, People involved…………. . B A C p E D F Has this problem happened in the past, if yes what was done? www. qualimations. com
Deep Analysis Testing the Good Testing the Bad Testing I caught the bad guy, now you Get me the good guy www. qualimations. com
Deep Analysis Bad System Problem part GOOD/BAD Good System No problem Part What Where When www. qualimations. com
Deep Analysis Find Relation ships Study if relationships could be established with the ambience Subsystems. Does change in conditions in subsystem-A influence the problem subsystem-P Can a relationship be established Between the subsystems Ambience B A D p C E F www. qualimations. com
Deep Analysis Process Flow: Study how this activity happens as a Sequence when produced or developed using a Process flow. Inputs Tools Human Factors Process 1 Sequence Analysis Output Characteristics A Process 2 C Process 3 B Process 4 p Output www. qualimations. com
Deep Analysis Testing/Sequence Analysis Going Deeper……. . Component replacement method: Use this method to find the sub system that contributes to the problem and also to identify the source of this problem. Correlation Method The correlation method is very useful to find the relation between characteristics in each subsystem and establish the relation to the characteristic in the Problem System. www. qualimations. com
Deep Analysis Testing/Component Replacement Replace one component or Subsystem at a time and study if the effect is consistent across both the good system and bad system. www. qualimations. com
Correlation Method involves the following procedure. 100% • Identify each characteristic in the problem system and all the systems that precede this process. Preference % Deep Analysis Relationships A C B p • Establish a one to one relation between the two systems characteristics. Girls Boys Output JD Power Survey result www. qualimations. com
Deep Analysis Establish relation ships between the characteristics in each system to the final output. Component to Characteristic Level Correlation Factors High No change Low Load Select one characteristic and vary its level, after keeping all other levels constant.

Deep Analysis Redefine the problem Categorize Your Problem and Go deeper to the failure mode Reoccurring Failure mode This failure mode occurred in the past and has been occurring again with a set pattern. First Occurrence This is never known to have occurred in the past but has suddenly started surfacing. You are here Random Occurrence This problem has a pattern of occurrence which cannot be found. Redefine the problem Problem as a final user www. qualimations. com
Deep Analysis Road Map Where are you now You have defined the problem You have viewed the problem from all perspectives You have zeroed on the location of the problem You have collected information regarding the history of the problem You know what characteristic when deviates leads to this problem. You know the mode of failure and know that when this corrected it affects your problem. www. qualimations. com
Deep Analysis Characteristic control Where is the problem? Most problems when gone In depth would reach a stage when a characteristic Is defined at a certain level. Identification of this characteristic-Level is very essential for finding the failure Mode. Bad Good www. qualimations. com
