Step six, construct co relationship within technical requirements. We now move to the top of the house to construct co relationship between technical requirements. positive correlation is shown as a white circle, and negative correlation is shown as a black circle. As a reminder, positive correlation means that if we improve one variable, the other variable would improve. negative correlation means that if we improve one variable, it would worsen the other variable. We find that weight of the portion and percentage of fat are positively correlated.

Likewise, a positive correlation exists between weight of the portion, ingredient cost and number of ingredients used. The team feeds That there is some level of positive correlation between taster taste, results and ingredient costs. Finally, number of ingredients used as a positive correlation between ingredient cost and time to prepare. There seems to be no negative correlation between any of these variables. That's fine. Let's move to the final step.
