paul, Do you mean " full launch"? In the business world a "launch" is the placing of a new product or service on the market. A "soft launch" is when you release your product or service to a limited audience in order to gain data for the product's use and acceptance in the market. A "hard launch" of "full launch" is when you make your product or service fully available to the general public and start a large marketing and advertising campaign in order to promote it.

做任何事前都要经过深思熟虑。。言之就是三思而后行

It means think carefully before you act
