One way of looking at the generation of higher levels of profitability is from the perspective of the reduction in the time allocated to adjustment activities. Unproductive is the company or professional whose activities lead to a relationship between adjustment times and those of primary production (the original generation of the product or service) greater than unity.
Let's think about who writes a letter and then that or another person should allocate between control and successive corrections equal or greater amount of time than the one destined for the original writing. Perhaps here the famous phrase of Napoleon Bonaparte can be understood when he said: "dress me slowly, I want to arrive early." Undoubtedly, by improving the spelling and grammar, and by clarifying the ideas from the beginning, it is feasible to elaborate the letter with a minimum of adjustments.
But it is certainly not about how fast the original work is done, but how well it is done, taking into account the planning, the person assigned to the work, the assigned material and instruments, as well as the methodology work and control.
Many have the belief, the custom and the paradigm of considering that a job is subject to successive adjustments, that the product can never be achieved well the first time, or even be close to it.
This idea must be totally eradicated.
It is very common to observe the aforementioned in software programmers, who after installing the program in the company go on to execute a large number of successive adjustments. These successive adjustments in both this activity and others uselessly divert resources to activities not generating new income, but rather destroying resources and generating conflicts with customers.
Today there are a number of methods and tools that allow avoiding such inconveniences, among them we have negative analysis, poka yoke, prevention systems, mind maps, the Ishikawa diagram, paretian analysis and applied statistics among many others..
The main thing is to become aware not only of the need, but also of the possibility of achieving products and services that are error-free "first time" or with levels very close to them (parts per million defects).
For the person receiving an HIV infected blood transfusion the error is not 1%, the error is 100% and it means death. To tolerate mistakes is to open the way to new and dangerous mistakes. Perhaps in many activities errors do not lead to biological death, but they can lead to the death of the company as an economic project.
