Seeking Alpha, January 13, 2008, by Seth Gilbert:
Ask a politician and they'll tell you, consistency in policy and staying on point is essential. Stick to the Message. If you flip flop from pro to con, then con to pro, credibility will disappear. Without credibility, there's little trust. Without trust there's won't be a favorable vote.
In retail, similar maxims apply. There's the famous "the customer is always right." There's also the old "K.I.S.S." principle: "keep it simple, stupid." You can confuse your customer with too many changes, or too many choices. That's bad marketing. Better practice is to offer them value, offer them what they ask for; what they want or need. Do that and they'll probably purchase your product. Don't and the sale is going to be difficult to close.
Lately, it seems more and more like Sony (especially the gaming division) has gotten off point, or keeps forgetting the message.
