The systems analysis approach is essential for any kind of problems, particularly for the design, tecnologies generation and processes operation. Any problem constitute an element of another and the most of them could be decomposed by own elements. By this, without systems analysis it is not possible to correctly face this world problems and particularly engineering problems. In the work attached you can find the basis of a metodological approach for facing engineering tasks.

If you work, by example, on historical problems, for a right understanding of any problem you must to find the link of the studied problem with the enviromment around it. That means you must to apply some analysis methododology. If your culture about systems analysis is not enought, then you must to do it empirally

Many years ago, I studied and practiced what was called Structured Systems Analysis and Design Methodology. The range of problems it could be used on was limited. I also later studied Soft Systems Methodology under Peter Checkland. The range of problems that can be applied to is significantly greater. Systems Thinking as a concept is powerful but it encompasses many methods and techniques some better suited to the analysis of some problems than some others.

This approach allows us to face studies of complex and interrelated objects, given the level of interconnection that sciences have reached, this approach is fundamental for our time and the most general assumptions of this approach are applicable to the study of any scientific problem, whatever it may be. the branch of science.

As an example we have the results of the investigations of Alpízar et al. (2009); Alpízar and Castro (2014), refer to the permanent training of the university director, the updating, professional and humanistic improvement of the academic directors for an effective performance; however, these authors approach the subject in such a diversified and enriched way, while involving so many references related to the subject, that someone pointed out "they seem to be killing sparrows with cannon fire."

Knowing that both in real life: in nature, society and in thought, tacit divisions are impossible to establish.

Each problem contains a series of interdisciplinary connections that seem infinite, immeasurable, but it is necessary to delimit their partial description, not to confuse what is written with what exists.

As the Polish-American scientist and philosopher Alfred Korzybski said "the map is not the territory"
