I use 'systems integration' as a phrase to describe applying insights learned in one field or discipline into another.
To solve a problem or achieve a goal, we try to find a way by which the seeming difficulty can just 'click' into place.
We all have solved many problems and difficulties in our lives, and our minds are depositories of useful or peculiarly interesting 'clicks'. Those 'clicks' are how an individual's mind 'works'.
The schooling system does much damage through conditioned overspecialization:
Knowledge is seen as a separate 'owned property' and not as an integral part of oneself. Knowledge is fractured further into classes or disciplines, and is reduced to mere parts of data.
Parts of data cannot function alone; the insight of the whole is needed.
This is where the most important aspect of learning lies: in the application of knowledge learned.
The schooling system omits the overview, the successful integration of knowledge, and thus omits to convey how or why the knowledge is useful to the learner.
A specialist is reduced to a mere mind-machine: the mind has been cast and molded into a strict form. The 'clicks' happen only one way. (Being expert is good, being specialized is not.)
I believe 'systems integration' is an important concept. Perspectives, insights, patterns, possibilities obtained in one field can and do contribute to a more wholesome understanding of another field.
There is no single way to understand, no single way to approach or solve a problem. If you think your way is the one true way - you are inflexible and can be manipulated.
