Fifth Step: Deployment
Often overlooked in poor system planning, this step can make or break an application.
Deployment consists of installing the tested system onto the customers’ computers and installing the up-to-date dataset.
The new system is then run in parallel with the old system to allow the users to gain experience and discover any lingering difficulties.
The final stage of deployment - stand alone is only started after consultation with the customer and agreement is achieved that the system and the users are ready.
