Car owners know that the ownership costs don’t stop with the initial purchase: there are preventative maintenance costs – oil changes, tune-ups, transmission flushes, and more; there are repair costs for issues like flat tires, oil leaks, and malfunctioning engines; and finally there are other costs like fuel costs and insurance. Over time, the cost of owning a car can exceed the initial purchase price itself.
In corporate IT environments, where the equipment purchase costs are only a fraction of the overall technology costs, professional IT managers are well aware of the total cost of ownership (TCO) and factor in the additional costs when making purchase decisions.
When evaluating network equipment for use in AV networks, one must take the same approach and consider the costs over the entire equipment lifecycle. Five phases of ownership factor into a product’s overall long-term cost: acquisition, setup, maintenance, upgrades, and decommission.
The initial purchase cost is often the most visible part of the total ownership cost. It usually includes the product costs, associated software, licensing fees (if applicable), corresponding accessories, delivery costs, taxes and any financing costs.
The cost of the product is based on a number of factors – the features, performance, components, quality, support, warranty and brand name. This initial cost is only a small portion of the total cost of ownership.
The planned service life is also a contributor to the initial product cost. Equipment in use for three to five years should be futureproofed – either through latest technologies or scalability features (e.g. number of ports, PoE, etc.). These considerations could increase the initial acquisition costs.
The cost of setup is often underestimated during the purchase consideration process. It comprises of the equipment installation at the project site, as well as configuration, integration and testing. Whether the costs are manifested in the form of billing hours or a service charge, three factors impact the final setup costs – the product configuration time, equipment vendor technical support and installer expertise.
Some equipment, like unmanaged (“plug and play”) switches, is so easy to install that it doesn’t require any setup. More advanced equipment requires technical knowledge and access through the unit’s internal management interface for configuration purposes.
Vendor technical support is critical when the installer is on the project site and needs help. Some manufacturers only offer online/web support—causing your work to stall for days at a time. Other manufacturers make you pay an additional service fee for around-the-clock/after-hours support. Still others have outsourced support services to individuals who simply read from a script and have no real problem-solving abilities. These costs, whether time or financial, are ultimately passed onto the buyer.
Over the lifetime of the network, periodic maintenance tasks are often required for proper operation, maximum performance and reliability. Some of these tasks include firmware updates, bug fixes, configuration setting adjustments based on updated network conditions, operational log reviews, performance tests, troubleshooting, warranty services (including replacements), and other physical inspections. These activities can be done as part of a service contract with the manufacturer (extended warranty/service contracts) or on an as-needed basis.
Maintenance costs will vary based on a variety of factors: some network equipment requires more maintenance than others, some activities can be done remotely instead of on-site, some tasks can be automated, some manufacturers offer free lifetime firmware updates while others charge fees after a certain period of time, and some manufacturers offer longer warranties than others.
In order for the network to function smoothly over its operational lifetime, the integrator must make sure it continuously meets the user’s needs. This may mean upgrading memory, adding more network ports, replacing obsolete devices, or adding new software modules. Not all products can be updated – the product could have reached “end of life” so that the integrator would have to go with a completely different platform. In other cases, the underlying standard has become functionally obsolete and cannot work with new products in the marketplace. Upgrade costs vary based on a variety of factors – system modularity, availability of software updates, ease of replacement, set up and integration of the new units, as well as the cost of the upgraded units.
An often overlooked expense is the cost of taking network equipment out of service. In smaller networks, it is relatively easy to do. In large commercial networks that are running continuously, decommissioning equipment requires coordination and advanced planning. Once removed from service, information stored on board the equipment must be removed. These include login names and passwords, IP addresses, log information, and other sensitive network data. Finally, there may be costs with recycling, disposal, documentation and compliance with applicable environmental regulations. These costs may be offset partially through vendor trade-in and trade-up programs.
Putting Theory into Practice
With so many variables in place, it is not at all uncommon for products with a low initial cost to mask hidden expenses that only appear in the long run. On the other hand, products with an initial high cost may save you money in the long run in their quality and services.
In order to properly assess the network costs over its operational lifecycle, ask yourself the following questions:
Consider the following checklist:
|Lifecycle Stage||Areas of Cost||Cost Reduction Items|
Now that you know what goes into calculating the total cost of ownership, how can you apply it? Here are some steps we recommend:
Like cars, networks involve a lot of tune-ups, and there is far more to maintaining a network than what is on the surface. With a little research and planning, integrators can potentially save themselves thousands of dollars in the long run.
