[Chaffey, Dave] Digital business and E-commerce 2nd book

test environment

  may be set up which 

simulates the final operating environment for the system. This test environment will be used 

for early user training and testing and for system testing. Finally, the  



production or live 

environment

  is that in which the system will be used operationally. This will be used for user 

acceptance testing and when the system becomes live.       

  

  Changeover 



 Migration or changeover from a previous information system to a new system is particu-

larly important for  mission-  critical digital business systems where errors in management of 

 

changeover

  will result in a negative customer experience or disruption to the supply chain.   

 When introducing a new  sell-  side e-commerce system there are two basic choices. First, 

the company can fully test the system in a controlled environment before it goes live and thus 

minimise the risk of adverse publicity due to problems with the site. Second, the company 

can perform what is known as a ‘ 



soft launch

 ’. Here, after initial testing, the site will be tested 

in a live environment where customers can use it.
