What is the tub curve?
People and products are connected by the concept of the bathtub curve - the term describes the shape of the frequency of death or failure relative to the age of a person or item. It has a characteristic shape at the beginning and ends with a long trough in the middle. The three phases contain the shape of the bathtub: the initial phase of infants mortality, the life of the useful and the stages of wear. The curve describes the characteristics of the population; In the first phase, it does not necessarily provide information about a specific sample member. This is the result of initial deficiencies: in humans, it may include congenital defects or genetic abnormalities, while products have production errors. Since this phase of infants mortality is proceeding, there are fewer cases, as the most serious problems result in immediate failure or death.
After the facade of death or failure ceases to reduce, the stage of the infant mortality has ended. At this point, the tub curve enters into the life phase. At this stage, only health or sound individuals and problems that occur,arise from chance or accident. The values in this section are generally much lower than in the other two phases.
Finally, the occurrence of death or failure will rise again, as people and objects age and begin to fall into bad health or break. These problems are the result of the person or item completed a normal life. The problem increases the shape of the bathtub curve.
Pressors and product engineers follow the bath curve for similar reasons. Both want to prolong the life of the life as much as possible and want to focus on reducing the example of infant mortality. They can see the effects of their decisions in that way, the chart changes.
In human cases, people act against the causes of problems. Take steps such as Mother's education for prenatal care and to achieve progress in medical technology to prevent infant death and prevent the effects of old age in the normal population. The result is the curve of the bathtub, toThe target has a longer trough with a lower baby mortality, which means that more people will survive to live a long and healthy life.
Product developers pair the search for causes with access to burning. They emphasize products before they are sent to customers to ensure that they survive only the strongest products. This helps them exclude products that have mistakes whose cause of developers has not yet identified.
