Why is Network Failure Threshold Testing so Important?
Simply put, the network failure threshold is the point at which your network breaks under real-world applications and user bandwidth. So is it better to know that before or after you launch your IT initiative?

To put it another way, from Nemertes Research's perspective (from their classic issue paper Strategic IT Initiatives need Strategic Testing): "Without proper testing, such strategic initiative can fail with serious unforeseen consequences, including significant hard dollar and opportunity costs." They also observed the gains expected from an IT initiative can be minimized or erased if the testing is not implemented before an initiative goes live.

Having the ability to assure the failure threshold is well above and beyond the projected use case and application utility profile of a network is critical to ensure the success of the initiative. Identifying failure thresholds is also essential to building in headroom for future-proofing a data center network initiative, so that your initiative scales with your long-term objectives and helps control unforeseen budget costs.

Some managers hesitate because they consider the cost of testing a low priority expense—and hence expendable. It's important to keep in mind the cost of mitigating the problem after the initiate goes live, along with the accompanying potential revenue loss and customer dissatisfaction. The old adage penny wise and pound foolish comes to mind.

The Nemertes perspective on the importance of timely testing is clear: testing should be performed throughout the life cycle of a strategic initiative and yearly budgets of allocating 2% to 5% for testing—including capital expenditures and operating costs—should be standard practice.
