When the order is delivered, installation will begin wiring the offices while systems sets up the server and installs the software. Installation can then finish the installation by connecting the network. After the system is connected, it must be tested and debugged before the reports go to management for acceptance. Once the hardware and software have been selected, the training staff can prepare manuals, develop training programs and train the users. The system will be installed and de-bugged, the users trained and the client invoiced before December 31.
Time is the driver.
Why, because if everything isn't done and billed by December 31, you won't get paid. It doesn't matter about the features or if you came in under budget. Missing the deadline is fatal. This is a little tougher. Depending on your company's culture, it could be either performance or budget.
