Microsoft &Xbox 

The process flow of Microsoft's Xbox manufacturing  is a long and rigorous process that takes the company a lot of time and money. To make a system it goes through various steps first they need to kick start the process by coming up with ideas for what the system will be and how it will change. Then they move on to the design of the system, this is where the product starts to take shape with what will be in it and how it will look. Next the engineering team tries to fit the pieces together to make senses of the design. After this the prototype is made to see if the concept works and i there are issues with what they have designed. the next step is for final checks and approval for mass production, From here it is sent of to the factory for mass manufacturing and and distribution. Finally the product is sold to the customers and then routinely checked for issues and bug by support teams.
