If you only focus on network ROI without minimizing "technical debt," you're likely fighting an invisible barrier that prevents your investment from realizing its full value.
In discussions about network upgrades and modernization, ROI is often the focal point: What returns will this upgrade bring? Is the return on investment high enough?
But looking only at ROI only tells half the story of "incremental benefits"—it doesn't tell you that the existing network is continuously eroding the value of your investment through its complexity, delayed upgrades, and capacity limitations.
ROI Quietly Dragged Down by "Technical Debt"
Networks are designed for the needs of a certain period, but needs change.
The network of the MP3 listening era is clearly no longer suitable for today's constant online needs. New applications are launched, more devices are connected, and automation is increasingly relied upon. If network capabilities remain stuck at past limits, a so-called "technical debt" will gradually accumulate.
Technical debt consists of:
· The ever-growing gap between what the current network "can do" and what modern applications/technologies "require."
· The long-term complexity left by decisions/temporary patches made to solve short-term performance issues.
It "accrues interest" like financial debt: the longer it's delayed, the more difficult and expensive it becomes. Technical debt accumulates over time, and the more it's ignored, the worse the situation becomes. The more upgrades are postponed, the more likely it is to rely on short-term solutions, which only make inevitable modernization more complex and expensive.
Why is "reducing technical debt" so difficult?
Much infrastructure isn't "broken," it's just no longer suitable for the future.
When budgets, manpower, and time are limited, it's easy to choose to "get by": temporarily patching things up with gateways, extenders, and stand-alone connections. It might work in the short term, but it will cause problems during subsequent upgrades:
· It will require time to figure out: How exactly should these temporary layers be integrated into the existing network?
· Can they be dismantled? How to migrate without disruption?
• Hasty planning increases the likelihood of decisions detrimental to long-term modernization, creating more technology debt.
Key Point - Develop a Roadmap for Reducing Technology Debt
Reducing technology debt doesn't always require massive resource expenditures, disruptive capital projects, or replacing all old equipment. Modernization offers flexible pathways that consider:
Network and its capabilities
The technologies you need to support
The resources available for upgrades
But all these paths require a plan. This plan begins with an assessment of the network to understand what's working well and what needs improvement if the organization has long-term goals to support.
If you don't have a clear picture of your existing environment, how can you ensure you're making the "right improvements" at the "right time"?
Conclusion
ROI is always important, but without incorporating technology debt into your decisions, your ROI is often eaten up by "invisible complexity."
Assess first, then plan, and implement in phases—making modernization less of an "all or nothing" gamble.
Belden Hirschmann is exploring new approaches to addressing technology debt. Through a service-based model and a trusted ecosystem of implementation partners, our goal is to make it easier for businesses to plan a viable, scalable modernization path, rather than viewing it as an all-or-nothing capital project. This allows you to derive more from your network and the technologies it relies on.
