Working procedure�此 �
Design�此�I cooperated with my collegues to figure out the climax of the performance�察�the musical acpaniment of the songs and the whole arrnagement ofthe narrative poem。
Rehearsal�此�I worked together with those who were in charge of the lights�察�sounds and scenes to create the perfect artistic effect。
On stage�此�I reminded my fellows with gestures and eye expressions。 Also�察�we coped with an emergency coherently。
The result�此�Our military team won the second prize in this petition。
6。 Activity�此�To hold the Perspective Entrepreneur Contest。
The innovative idea I produced�此�To simulat a board meeting of a pany�察�in which our candidates debated the feasibility of selling modern fitness equipment according to the market information they collected。
The result�此�The contest was hold based on my proposal。
7。 Background�此�On one morning when our promotion month first began�察�I found that the inventories in some department stores were not adequate。
My assessment of the situation�此�The four promoting stores were not very far from each other�察�and the time they opened was not the same。 It was possible to fetch some stock from another store and made up for it later。
The priorities�此�To satisfy the stocking demand of the store which had the largest number of customers。
8。 Background�此�In the inverstigation of customers¨ opinions about the taste of a new kind of beer�察�I found that the questionnaire form was out of date and limited the freedom of the responsers¨ choices。
Technical skills�此�The scientific arrangement of questionnaire form
The result�此�With the help the converted form�察�our pany obtained more objective and effective information。
