At noon one day, my husband called at home: "dear wife, can I bring some colleagues home for dinner at night ?" (Order intention)
Wife: "Of course. How many people are there? What kind of food do you want to eat ?"
Husband: "six people, we'll be back around 7 o'clock to prepare some roast duck tomato scrambled egresses and egresses... can you see it ?" (Business Communication)
Wife: "No problem, I will prepare it," (order confirmation)
My wife records the menus to be prepared (MPS plan). The specific dish to be prepared: Duck wine tomato and eggs for oil ...... (BOM material list): 1 duck, 5 bottles of wine, 4 tomatoes ,...... (BOM expansion). It requires 6 eggs for scrambled eggs and 4 eggs for egg soup (shared materials ).
Open the refrigerator and check (warehouse). There are only 2 eggs left (out of stock ).
When I came to the free market, my wife said, "How can I sell eggs ?" (Procurement inquiry)
Hawker: "1 yuan, 5 yuan for half a dozen, 9.5 yuan for one dozen ."
Wife: "I only need eight, but this time I bought one dozen ." (Economical batch procurement)
Wife: "This is a bad one, for another ." (Acceptance, return and exchange)
Go back to your home and prepare for cooking and cooking ...... (Process route), the kitchen has a gas stove, microwave oven, rice cooker ...... (Work Center ). My wife found that it was the most time-consuming to pull the duck hair (bottleneck process, key process routes). It may be too late to cook the roast duck in a microwave oven (insufficient production capacity ), so I decided to buy a ready-made restaurant (out of service) in the restaurant downstairs ).
At four o'clock P.M., the phone rang again: "Mom, I want to come to dinner at night. You can help me prepare ." (Urgent order)
"Okay, son, what do you want to eat? Dad has guests at night. Would you like to eat with them ?"
"You can do it, but you must have tomato scrambled eggs. We don't eat with adults. We'll be back around ." (Haha, it cannot be processed separately)
"Okay, you must be satisfied ." (Order confirmation)
The eggs are not enough. Call the hawker to send them. (Urgent procurement)
At, everything was ready, but the roast duck had not been delivered yet. He hurriedly called and asked, "I'm Mrs. Li. How have I ordered the roast duck ." (Procurement outsourcing ticket Reminder)
"Sorry, the shipping person has already left. It may be a traffic jam. It will arrive immediately ."
The doorbell rang. "Mrs Li, this is your roast duck. Sign one word on the ticket ." (Acceptance, warehouse receiving, transfer to account payable)
At, my daughter called: "Mom, can I bring some friends home for dinner now ?" (Oh, it's an urgent order intention, and the spot is required)
"No, daughter. Today, my mother needs to prepare two meals. It is too late. I am really sorry. I will say it later and I will be ready for you ." (Haha, This is the limitation of ERP usage. A stable external environment is required, and a minimum advance stage is required)
After all the guests were sent away, the tired wife sat on the sofa and said to her husband, "dear, we have a very high frequency of buying kitchen supplies (equipment purchase ), it is best to hire another nanny (even the HR system has interfaces )."
Husband: "You are the master at home. You can do whatever you need ." (Approved)
Wife: "also, my family has spent too much money recently. I will use your private room money to subsidize it, OK ?" (Hahahahaha, and finally the reminder of the receivables)
Does anyone understand ERP? Remember, every qualified housewife is a strong competitor of the production director !!!!!
