Technology is on a one-way trajectory and won’t slow down for anything. Or anyone. With it’s blunt force, the pressure on C-Suite to keep up with the cavalcade of AI advancements is no easy task.
One major hurdle to the many businesses peaking curiosity in this new state-of-the-art paradigm: Technical debt and the burdensome cost of maintaining legacy systems.
That’s why an understanding of the financial and operational impacts of technical debt is crucial for any business aiming to optimise their IT budgets, drive innovation and stand a chance in .
Understanding Technical Debt and Legacy Systems
Technical debt refers to the hidden cost from opting for quick, easy solutions rather than a more robust, long-term approach.
Similar to putting a plaster over a clearly problematic wound; it’s not noticeable, but the future cost and terror of ripping it off will always be far worse.
There’s even a list of terms defining each style of incurring this sort of debt:
- Ad-Hoc development: Rushing to develop for immediate gratification, with absent consideration of the long-term.
- Firefighting: Quick resolutions to big issues using temporary fixes (more shady architecture).
- Workaround Engineering and Technical Improv: More temporary solutions with no grasp of the root cause and/or concern for the future.
- Band-Aid solutions: The application of temporary fixes or patches that help mask, as opposed to address, symptoms.
This concept is vital in understanding how legacy systems drain IT resources. As Isaac Sacolick puts it, “CIOs have good reason to stress out over rising technical debt and the impact of supporting legacy systems past their end-of-life dates.”
The longer these systems are in place, the more resources are diverted from new initiatives to maintain legacy technology.
Statistics and Financial Implications
The Cost of Technical Debt
Forbes reveals that organisations estimate that technical debt can consume between 15% to 60% of their IT budgets, depending on their specific circumstances.
A McKinsey study found that 20% to 40% of a company’s technology value is tied up in technical debt, a figure often invisible in financial statements. For a project with one million lines of code, the annual cost of technical debt can reach approximately £240,000, which translates to around 5,500 developer hours spent on remediation.
Over five years, this can escalate to £1.2 million.
Then there’s budget diversion.
More than 20% of technical budgets for new products are often redirected to address existing technology issues, particularly those related to integrating legacy systems with new solutions.
This diversion hampers innovation and slows down the deployment of new products and services.
Impact on Productivity
The costs just keep escalating.
And that’s because technical debt has a direct impact on productivity. It frustrates and slows down team efforts and creates more room for the wrong expertise (like data scientists and engineers spending hours mitigating these problems).
Engineers reportedly spend about 33% of their time managing technical debt. Various studies indicate that organisations waste between 23% to 42% of their development time dealing with related issues.
Why you should actively manage technical debt? Besides freeing up engineers to focus on more important initiatives, it’ll potentially increase their productive time by up to 50%.
Organisational Challenges
Inefficiencies and Integration Costs
Legacy systems, with their outdated and siloed structures, lead to inefficiencies, delays, and missed opportunities.
According to a host of sources, the problems are:
- Businesses estimate that technical debt can consume 15% to 60% of every pound spent on IT, depending on the specific circumstances and decisions made within the company.
- More than 20% of technical budgets for new products are often redirected to address existing technology issues, particularly those related to integrating legacy systems with new solutions.
- Maintaining legacy systems may require specialised skills and hardware that are difficult to find and expensive to maintain. Additionally, the longer an organisation waits to replace legacy system components, the more costly and time-consuming the transition becomes.
- Legacy IT systems impose substantial ongoing costs that can strain resources. The complexity arises from managing multiple customisations and integrations to ensure effective communication between disparate systems, which adds overall cost.
Plus, integrating new technologies into an ageing tech stack can be challenging and expensive. More often than not, resulting in higher integration costs and project overruns.
Morale and Innovation
As Isaac Sacolick notes, “CIOs sitting on mounting technical debt must turn paranoia into action plans that communicate today’s problems and tomorrow’s risks.”
It’s clear: Technical debt negatively impacts developer morale.
Teams often prioritise new features over essential maintenance, leading to frustration and decreased productivity. More than half of engineers believe that a structured approach to managing technical debt could allow their teams to ship products up to 100% faster.
Failure to Address Debt
McKinsey reveals that companies in the bottom 20% for managing technical debt are 40% more likely to have incomplete or cancelled IT modernisation efforts compared to those in the top 20%.
The failure to address technical debt can significantly hinder a company’s ability to innovate and remain competitive.
The Path Forward
Addressing technical debt and modernising legacy systems require a strategic approach.
Companies need to prioritise modernisation efforts and foster a culture that values long-term solutions over short-term fixes. This involves:
- Clear Action Plans: Define non-negotiables and seek agreement with the board and executive committee on when upgrading legacy systems must take priority.
- Data Modernisation: As DigitalRoute emphasises, “Bad data is costing businesses trillions of dollars a year. Those that are still keeping their legacy systems around need to level up and consider modernising their data infrastructure.”
- Fostering Innovation: Freeing up resources by effectively managing technical debt allows companies to focus on strategic initiatives that drive innovation and growth.
Tackle Technical Debt (With Experts)
We can all agree that technical debt and the unwavering reliance on legacy systems represent significant challenges for businesses.
But by adopting a strategic approach to manage these issues, companies can enhance their operational efficiency, improve developer morale, and ultimately drive innovation and growth.
