Facebook internal data: Product Design evaluation system decryption

How to judge the design, there must be many answers, pros and cons. Ask 100 designers and get 100 answers. With the online PV, UV and other data to speak, more by product attributes, operating action impact; User research, often get a one-sided view of the user perspective, lack of professional guidance advice; With the satisfaction of the demand side, it may be the last thing the designer thinks is the most abusive scheme.

Both are hung with "the first place" adjacent to sell stinky tofu chef.

Which of your stinky tofu smells?

Answer: "I"

Which of your stinky tofu tastes delicious?

Answer: "I"

So who the hell is your stinky tofu?

The stinky tofu in their house ...

Designer: "I think my design is no problem from my professional perspective"!

Let a designer to evaluate the work of another designer, like to ask the chef to sell stinky tofu, often get a one-sided view, mutual negation, basically from the ego-centric way of thinking.

Then we must naturally think, let the user say who's stinky tofu delicious not on the line, see who's Team row long? Stinky Tofu Master will say a variety of reasons, what the location, flow direction, fermentation temperature, raw materials and chengguan. And designers in a company's role often does not sell stinky tofu in this market, in the resource shortage, the demand side often will not be too much to pursue quality, a lot of time to do is also used to give designers a demand side is very satisfied with the illusion.

Good design is a boast, do not negate any works, only praise outstanding works.

Designers really want to know where the work can be improved, but not to accept the negation of his work and do not tell him why the way of expression.

Find some so-called expert guidance, designers are often inconsistent and "but so".

Collecting feedback from some users, designers are often ridiculed and "they do not understand."

Evaluation is actually a measure of business with a standard

First we have to set standards and have common standards for referees. And the standard is not good or bad right and wrong, the key in all the designers are fair, to avoid individual designers Ji-ji Crooked, because "everyone is the same."

Rules, the judges must be more than 4 people, not 4 people are a taste. Each high score must be given a reason, the judges can only be considered. Finally, 50% of the points are from user research, multiple data combinations, the accuracy greatly enhanced.

And the online data statistics of the five-D curve and the judges of the five-dimensional curve if the same level, then the review is basically successful.
