Factory Built vs. Field Built

Home / Factory Built Network® / Factory Built vs. Field Built

In a traditional field-based deployment process, network deployment occurs in separate customer locations.  Equipment is shipped to each location and stored onsite until the time of installation, or shipped to a central warehouse for handling and distribution.  Field engineers travel to each location, validate the kit, and complete the installation, provisioning and testing of the network, staying in nearby hotels until the job is done.  If a part is wrong, or missing, or fails out of the box, it would be reordered and shipped to the appropriate customer location.  Field engineers would need to come back to this location on another day to complete their work.  Given an industry standard out-of-the-box failure rate of roughly 2%, such part failures would cause return trips by field engineers in at least one customer location.  It is likely that these part problems would occur in multiple customer sites for a network deployment with a large number of network nodes.

An escort is generally provided by the customer to let the field engineers into the data center or cage, and to oversee their work.  In the event of a return visit, the escort would need to be scheduled again and paid for the time required for the field engineers to complete the project.

In contrast to a traditional field-built approach to network deployment, most of the work in a Factory Built Network process occurs in a central facility, or “factory.” This difference allows a provider to implement more of a production process, from inventory management to high volume construction. It also enables the use of experts for each step of the deployment process, and the resolution of part problems before the networks leave the factory.

In a centralized laboratory setting, or “factory,” the system integrator can lay out all of the parts and equipment and construct the networks in the most efficient manner possible, bringing in highly experienced specialists as needed for each step of the process.

Installation can proceed more methodically. Integration, commissioning and custom tuning of each part of a system can be completed by the most appropriate expert for the specific type of equipment, software or network. If a system design question arises, an in-house network design engineer can be readily consulted. Failed parts are identified and replaced early in the process, and shipped to the system integrator’s facility – eliminating the traditional need for extended stays at customer sites, extra trips to remote locations or increased expense for customer escorts.
