Utilization of Flow Chart (流程圖運用)
Example 1. Find out the problem area for CEDAC analysis
(發現所存在的問題给予CEDAC圖分析。) 2. Pareto Chart - look for area where critical defects occurred
3. Compare both charts, looking for areas where they are different (比較兩個圖，找出不同之處)
4. Identify potential improvement area (識別待改善之處)
5. Take appropriate steps to correct the differences between the two flows (使用恰當的方法改進兩個流程的差异)

Construct flow chart of actual process (流程圖的實際工序)
2. Construct flow chart of plan process (計划過程)
Flow Chart Introduction (流程圖介紹)
• A pictorial representation describing a process being studied or even used to plan stages of a project (它是一种通過繪圖來描述某一個項目的計划實施過程和步驟。)
(用于商務或信息分析)

Waiting for next process (等待下工序)
Packing (包裝)
• To provide people with a common language or reference point when dealing with a project or process (它是我們在處理某一個項目或過程時的通用表達方式.)
Start (開始)
Decision? (判斷)
(儲存(物料箱/成品踏板/倉庫<有記錄>))
Delay: Wait for elevator, papers waiting, wait for next process. (without record)
(推遲：等待電梯/文件/下一工序(臨時 存放，無記錄))
Process 1 Process 2
(如果產品測試合格，則搬運并等待下一工序) Step 4 Product send for rework/repair if fail functional test
(如果產品功能測試不合格，則送去返工或修理) Step 5 Finally, the finished product send for packing
Question: To draw a flow chart for the following process: (問題：請按下面的步驟畫出相應的流程圖)
Process: To find out the best way home (發現最佳的回家方式) Step 1 Leave Office (离開辦公室) Step 2 Walk to bus stop (步行到汽車站) Step 3 Check for available bus (尋找可乘坐的車) Step 4 Which bus reach home faster (哪一輛車回家更快) Step 5 Take the bus (選出該乘的車) Step 6 Reach home early (提早到家)

(找出主要缺點或主要影響因素的区域给予柏拉圖分析。) 3. Control Chart - look into detail area where control chart may be applicable
(找出给予控制圖觀測的具体區域。)
Type of Flow Chart (流程圖類型) 1. General use (慣常使用) - most frequent used symbols (經常用的符號) 2. Production use (生產使用) - used for production analysis (用于生產分析) 3. Business use (商業使用) - used for business and information analysis
