《 Phoenix Project —— One IT Legend of operation and maintenance 》
This is a very rhythmic book , As the translator said ,“ I really want to read it in one breath ”, After all, fiction is always more fun than technical data .
For many people , The story in the book , It's what's going on , Or everyone will meet , And tell you how to solve it , How to speed up the story of business recognition .
The translation of this book is generally acceptable , Although the name of a person , There are more or less minor mistakes in terms , Occasionally a little stiff , But it doesn't affect understanding ~
Here is my personal understanding , For reference only :
Three working methods : 1, Optimize development to operation and maintenance workflow ( Execute by workflow ) --------- method : Continuous construction / integrate / deploy , Strictly control changes , Kanban 2, Fast value flow , Continuous feedback ( feedback )  
            --------- method : automated testing , agile 3, Building culture ( study , practice )                        
--------- method : Continuous improvement
Four types of work : 1, Business project 2,IT Internal projects ( Let's say it's routine work ) 3, change 4, Unplanned work ( accident , problem )
% busy : This is a picture of a book that I think is very good : waiting time = ( % busy )/( Percent free )
The shape of the curve indicates , When resource utilization exceeds 80% Time , The waiting time will rise in a straight line , The destruction caused by high resource utilization is fatal . If not handled , The task queue will never complete .
last : Expect all functional links ( development ,QA, Operation and maintenance , Business unit, etc ), Top down thinking , When the problem occurs , All parties can understand and realize each other :
“ If development and IT No operation can achieve their own goals , This will inevitably lead to disaster , In the end, everyone is the loser of the internal war .”
For many people , The story in the book , It's what's going on , Or everyone will meet , And tell you how to solve it , How to speed up the story of business recognition .
