Nominal - Magical Number Seven, Plus or Minus Two

About

In every design implying a nominal, the rule of Magical Number Seven, Plus or Minus Two states that the number of nominal value should not be more than <math>7 \pm 2</math> otherwise the brain will not be able to cope with it, ie:

  • to remember it (ie more than 10 departments)
  • to manage them (ie team of more than 7 members)
