1 Logical Root Cause Analysis (LRCA) cannot not can Save time by a factor of > Project 1 Project 2 With LRCA in weekdays Without LRCA in weekdays

2 Why trying to save time on problem analysis at the beginning costs time? PROBLEM 1) Problem occurs 2) Taskforce meeting ) Problem-solving process becomes a matter of trial and error 4) Consultants perform LRCA and identify the root cause within 3-5 days 5) Targeted solution strategy resolves clearly defined root cause

3 Using Logical Root Cause Analysis (LRCA) at the starting point saves you time, effort and money? PROBLEM Thanks to LRCA the root cause is either identified directly or the most efficient experiment is set up in order to gain full certainty about the true root cause

4 LRCA builds on the best features of state-of-the-art methods for problem analysis and corrects their short-comings Fishbone Diagram Current Reality Tree Root Conflict Analysis A A B C D E F G H I J * Ishikawa, Guide to Quality Control, * Goldratt, It s Not Luck, * Souchkov, Application of Root Conflict Analysis, K B - - K + H & C D I L + Problem causes are brainstormed according to predefined cause categories - No cause-effect relations between potential causes Problem causes are brainstormed and put into a logical order of cause-effect-cause - No use of problem specific - Incomplete analysis because categories causes are not logically deduced - Only root causes identified, no root conflicts Problem causes are identified and put into a logical order while root conflicts (causes for negative and positive effects) are highlighted - Incomplete analysis because causes are not logically deduced

5 LRCA identifies root causes (and their related root conflicts) by logical decomposition right from the get-go Fact 4 Fact 3 Fact 2 Fact 1 1. Specification of the problem What? Where? When? Extent? Is Is not Distinction * or 2. Logical decomposition of the problem as effect of causeeffect-cause relations representing relevant knowledge from all necessary specialisations in one picture 3. Identification of root cause (and its related root conflicts) or most efficient experiment to identify the root cause Formulation of sentences is normed such that the following domino structure can be realised consistently A Verb B B Verb C C Verb Different cause-effect-cause chains are connected by the following operators AND OR AND/ OR Every layer of causes is systematically derived from the effect that is to be decomposed D * Kepner and Tregoe, The New Rational Manager: An Updated Edition for a New World, 2013.

6 Proven by experience: LRCA saves time by a factor > 100 In two projects with a European automotive supplier we successfully analysed two long-existing problems by means of LRCA The problem in project 1 hadn t been understood for 1.5 years and the problem in project 2 for 2.5 years The analysis of the first problem took us 3 days, the analysis of the second, 5 days 3 5 The company would have saved enormous amounts of time if the LRCA had been carried out right from the start Project 1 Project 2 With LRCA in weekdays Without LRCA in weekdays

7 Do you have a problem and want to save time? Skip the taskforce meeting and book an LRCA session! LRCA!? PROBLEM We provide LRCA in the form of consultancy and training. For more information write to justus@secondnegation.com, co-founder Consultancy & Training

The goal of our approach is to quote the logician Ludwig Wittgenstein to show the fly the way out of the fly bottle.
