A critical review of the book It's Not Luck by Em Goldratt Extensive use of Goldratt's thought process is applied in various activities as part of problem solving. “It's Not Luck” highlights the importance of using thought processes in business and personal life. Thought processes refer to a logical, graphical, general and practical method of problem-solving methodology and basically consist of 3 phases. These steps described by Goldratt are:1. What to change?2. What to change?3. How to bring about change? It is very clear that the problems experienced in companies are not isolated but in most cases they depend on each other and there are strong links or relationships regarding the cause and effects between them. It is therefore important to form or establish a strong cause and affection between them. It is important to identify the unresolved conflict that exists. The process can be illustrated through a conflict resolution diagram or an evaporating cloud, Goldratt (1994). As a first step, a “current reality tree” is used extensively to portray and represent the cause and effect that unite all problems occurring in a specific situation. After that, you will realize that there is no need to deal with more problems because normally there are only one or two reasons or causes. The thought processes give you a step by step procedure on how to do this. This is where undesirable effects (UDEs) come into play. This brings us to what to change. If the unwanted effects lead to the root cause, then the root cause must lead to the unwanted effects, therefore “led by the root cause itself”, Taylor (2003). The resulting current reality tree takes us to the process...... middle of paper ......reducing their inventory levels. Throughout the text of “It's Not Luck” it is clearly evident the great and significant importance detailed and accurate information plays in making informative business decisions. The information positively contributes to clear and logical decision making as well as analysis that further helps in achieving the desired goal and objectives. The book "It's Not Luck" with its three business examples clearly illustrates that when a constraint is removed, results advance. In this way even normally ambitious goals can be achieved and achieved and the goals will be realized. References: Goldratt, E.M. (1994) It's not luck.
