Gossip: an initially perfect FS is as impractical as the first version of the program requiring no bugs

See what agile development is talking about in the Group Waterfall mode and so on ,

Many viewpoints mentioned by a foreign friend are very good . 

I remember when I first started my career , Ask the business consultant to provide a very detailed FS, Then I followed FS Just do it . At that time, on the one hand, my needs were relatively simple , In addition, my level is not high , This is the only way .

Especially the ideal project , Some business consultants are great , Some adjustments and modifications ,FS Even which program to modify the first few lines are given , Can even give code .

With seniority , Slowly, I'm sure I won't just do some simple needs , It's not just a simple modification , A simple report, a simple enhancement and so on .

It may be that a complete need needs to be completed by yourself .

For example, four years ago It's done SD The platform of .

What the customer requires is one click operation , Just click the button to finish the whole process .

It involves some interfaces to receive data and feedback Push a third party , Another part is to take the lead .

There are also many enhancements involved   And other customized things .

Any other step may go wrong , Monitoring and reprocessing after errors .

This thing , Actually, it's really disgusting , But Party A requires , Take people's money to help people deal with disasters , As for reasonableness , People want to , You have to .

I developed this thing , The business consultants are Lao Wang and Xiaoqiang . It took a month to develop .

Involving interface reception push , The basic functions are realized in the forward and reverse directions , Initialize import , Batch Guide , Batch adjustment and modification , Monitoring platform .

There are some financial things behind .

I haven't seen much of this thing since it was developed FS, I sit with Lao Wang , Lao Wang said orally , I'll write , If you encounter problems in the process of writing, please feel free to contact Lao Wang , After writing a part, let Lao Wang test a part , Then I will do the following requirements . At that time, the project was too tight .

Lao Wang knows the code , I know a little about business , The cooperation is quite tacit .

The first edition came out soon , The rest is to change the part bug, Deal with special situations .

What's more, Party A suddenly said that the company has any special circumstances ,

What can be like this or like that , ok ……

The pit has been dug anyway , It's nothing more than digging an extra shovel .

Actually MMSD It's okay , It's relatively simple .

Some more PP APO What? , More messy . That's more disgusting ,

Oh, and EWM Of , A complete set of functions , Ah ……

Consolidated financial statements , Self developed consolidated statements .

To say , These pits are almost digging through the earth .

Can't , Who makes Jin the main ？

Once the function is complex , There can be no complete FS, Especially domestic projects , An evening FS How long will it take ？

Just have a rough idea of complex functions , First, realize the basic functions , Then add special logic .

To provide a perfect copy at the beginning is FS It's really the same as the first version of the code bug equally .

Impractical .

Complete the most basic , Repair bug, Add special logic , Repair bug……

Go round and begin again .

Finally, add a picture , Um. , Everybody knows that ……
