System integration is the process of linking together various IT systems, services, and/or software to enable all of them to work functionally together. With regards to software solutions, system integration is typically defined as the process of linking together various IT systems, services, and/or software to enable all of them to work functionally together.
System integration typically occurs in phases. In phase one, a customer requests that an integrator develop a solution. This solution is typically described in a functional specification document. In phase two, the integrator develops the solution by implementing the functional specifications described in the functional specification document. This is typically done by writing software code. In phase three, the integrator tests the solution to make sure it meets the customer’s needs. If not, the integrator will revise the functional specification document and return to phase two.
But how does system integration differs in the Era of IR 4.0?
