From neurobiologic point of view the brain is not made for learning by heart of following instructions, but for solving of problems A brain can not be changed by pulling and pushing The brain has to be touched emotionally
Activation of the emotional centres in the midbrain leads to dispersion of neuroplastic transmitters which show effects comparable to brain-fertilizer
People only achieve their full creative potential for problem solving if they get stimulated by enthusiasm
Enthusiasm is an important and effective multiplier for neuronal remodeling processes

SPALTEN – PE Extrusion of window-profile: IS / IS Analysis
Ident-Nr. 112269
IS IS Which object has anomaly?
Which anomaly exactly? Main window profile XY Surface quality under-runs limit
Where did the anomaly occur on the object?
Top side (surface xy, on an area of … mm)
Which similar objects are not affected? Main window profile XX All other profiles of the same category
Which anomaly could have
been occurred, but did not? Other plain surfaces of the profile Other profiles of the same type

SPALTEN – PE Extrusion of window-profile: IS / IS Analysis
Ident-Nr. 112272
IS IS Where exactly was the
object when the anomaly occurred? Not exactly known when and where in the production process
When did the anomaly occur first? When was it observed?
Was first documented at …
Where else could an anomaly occur? Where else could the object be? Surface damages can occur in the following packaging processes
When else could it have occured first?
Max. 2 hours before (because of the testing frequencies

SPALTEN – PE Extrusion of window-profile: IS / IS Analysis
Ident-Nr. 112273
IS IS When and how did it occur
again? Sporadically, periodically, continuously? Started sporadically, 6 hours later it occurred continuously
How will the future development of the anomaly be? Which trend can be recognized?
Surface quality will decrease constantly
When else could it have been identified first?
See above Which other trend could have
been happened? Surface quality could stay on a certain level
