If the product requirement changes

Preface: have already identified the product demand changes how to do, why change, how http://www.aliyun.com/zixun/aggregation/10355.html "> mining demand?"

First look at the background:

The product is an Internet café platform, the Netizen participates in the platform the activity or plays the game may obtain the silver coin, the silver coin may exchange the prize such as: NET fee, point card, QB, telephone bill. The prizes are provided by Internet cafes and can be exchanged in the platform for Self-Service. Later, in order to promote the XX game and custom exclusive prizes, the product introduced gold coins. Set up by the Internet café to play xx game to get gold coins, activities and games can participate at the same time play games when the platform automatically issued coins and silver coins.

Then analyze the business logic and product expectations:

1, the Internet café set lol point card needs gold coins + silver coins can be exchanged, and play lol can get gold coins, and then promote more people to play lol, longer.

2, Internet cafes and games to promote XX games, and then set up prizes (such as the ipad, IPhone, phone calls, etc.) need to exchange gold coins, playing xx game to obtain gold coins.

3, netizens hands too much silver, resulting in prizes often against light, and internet cafes wrong use of gold coins to control the stock of ordinary prizes, contrary to the original purpose of the coin: promotional and exclusive prizes (such as gold coins can only change the corresponding game point card, in case the user does not play the game)

Then our product department ushered in a stark fake demand feedback:

As a result of the Internet Café set popular prizes (such as phone calls, Q-coins, etc.) need gold coins, and do not play the game of netizens can not get gold coins, resulting in resentment of the sound of the four (not suffering from a lack of uneven), Internet cafes overwhelmed. So some internet cafes proposed silver coins and coins to exchange the sound.

Later, the boss and demand analyst discussion again, meeting again, although I insist that gold coins can not be exchanged. There is a popular result: Silver coins can be changed, gold coins can not change silver. However, make the product easy to make mistake everybody knows, May next month, also must open the gold coin to change the authority of the silver coin.

Well, it's time to summarize the reason:

1, our product guidance is not in place, failed to let the Internet café fully understand the meaning and value of gold coins (product interaction to improve, operations to follow up).

2, too let the user appearance.

3, do not dare to adhere to the product Requirements/principles (IOS7 persisted, scold the voice replaced by the hymn).

Now go back to the title:

In the silver coin/profit statistics there, silver coins for the cost of how to calculate ah, the silver coins are not consumed, but the equivalent of the gold coins, like soft sister currency for the United States knife. Once again, how can I explain to research and development!

On the table:

Come, dry this beer (need) wine (please)!!

I have a wry smile on research and development.
