The barriers could be listed in the order in which they need to be solved, or elements of the problem classified in a number of different ways.
Chain Diagrams are the simplest type, where all the elements are presented in an ordered list, each element being connected only with the elements immediately before and after it.
Chain diagrams usually represent a Flow charts allow for inclusion of branches, folds, loops, decision points and many other relationships between the elements.
In 1949, Wasserman and Wolf devised an analytical method for portraying the problem and gave it an official name—the Wasserman-Wolf problem.
They recommended that the best way to deal with the problem is to use two aspheric adjacent surfaces to address aberrations.
In his works, he recommended that the impact happens because the lenses were spherical—light striking at an angle couldn’t be focused as a result of contrasts in refraction.
Isaac Newton was allegedly stumped in his endeavors to solve the problem (which wound up known as a circular variation), as was Gottfried Leibniz.
In many organisations it is possible to set up formal systems of communication so that problems are reported early on, but inevitably these systems do not always work.
Once a problem has been identified, its exact nature needs to be determined: what are the goal and barrier components of the problem?
Chain diagrams are powerful and simple ways of representing problems using a combination of diagrams and words.
The elements of the problem are set out in words, usually placed in boxes, and positioned in different places on a sheet of paper, using lines to represent the relationship between them.
