Buying the equipment is one milestone in a commercial AV project. The system still needs configuration, programming, testing and handover before staff can rely on it.
Equipment affects the programming scope
The control interface, source names, display commands, audio routing and room modes depend on the equipment that is actually supplied. A late model change can therefore affect configuration and testing.
Allow time for the system to become usable
On a larger institutional project, the programming allowance grew as the requirements became clearer. That is normal in complex work. The final scope should state what is included and what changes may require additional programming.
Keep procurement decisions visible
Availability, substitute models and backup equipment should be recorded before ordering. The programmer, installer and client should understand which changes are acceptable and which would affect the agreed room experience.
For Crestron boardroom systems and commercial AV, DG Technologies treats procurement, programming and commissioning as connected parts of delivery.
