開發流程如下：

·項目計劃

?? 完成這個項目需要的時間：7天

·項目開發

??·需求分析：

??? ·作為一名排球計分員，我希望在觀看比賽過程中能實時記錄并顯示比賽雙方的每一次的得分情況，以便于我能更好的去記錄比賽得分，并將每一次得分實時的顯示給觀眾（精確到每一次得分）。

? ·設計文檔

??? ·由排球比賽用戶故事的需求分析可知，此程序是用來準確記錄比賽雙方的每一次得分情況，并及時顯示給觀眾，且顯示比賽的勝負結果的。

??·計劃復審

??? ·正在進一步的商討中。

??·代碼規范

??? ·根據Visual Studio 2010規范去寫。

? ·具體設計

??? ·UML活動圖：

??

??? ·UML類圖：

?

?

? ·具體編碼

??? ·部分代碼如下
