When collaborating with others – especially when designers and programmers are part of the mix – watch out for these dirty four letter words:

  • Need
  • Must
  • Can’t
  • Easy
  • Just
  • Only
  • Fast

They are especially dangerous when you string them together. How many times have you said or heard something like this:
“We really need it. If we don’t we can’t make the customer happy. Wouldn’t it be easy if we just did it like that? Can you try it real fast?”
Of course they aren’t always bad. Sometimes they can do some good. But seeing them too often should raise a red flag. They can really get you into trouble.
