Innovation is good. Maintenance is too.

Innovation makes headlines. Companies announce new digital platforms, investments in artificial intelligence or technology transformation projects. These initiatives spark interest, project modernity and make it possible to showcase progress.

Maintenance, by contrast, rarely receives the same attention. Few organisations announce that they have invested in upgrading their servers, reducing technical debt, strengthening security or improving the reliability of their systems.

Yet these actions also create value, even if their results are less visible.

In the digital environment, we take it for granted that applications work, services are available and our data remains protected. It is only when something fails that we tend to pay attention to the infrastructure that makes it possible.

Perhaps we should reconsider how we understand progress. Why do we associate it more with what we add than with what we manage to preserve, improve and make more efficient?

Because not everything that creates value needs to become something new.

Digital infrastructure ages too

Although it is not always obvious, digital infrastructure ages too. A server may continue running with outdated configurations, an application may depend on libraries that no longer receive updates, and a website may remain operational on a version of its content management system that is no longer supported.

The same applies to databases that grow without an optimisation strategy, systems whose operation is known to only one person, or backups that are made regularly but whose restoration has never been tested.

These situations can go unnoticed while everything appears to be working well.

In software development, we speak of technical debt to refer to the future cost created by certain decisions, temporary solutions or improvement tasks that are repeatedly postponed. As with financial debt, it does not always represent an immediate problem, but it can build up and make systems harder to evolve.

However, it is important to distinguish between age and obsolescence. A technology is not necessarily insecure or inefficient simply because it has been in operation for many years. Its reliability also depends on the maintenance it has received, the availability of support, its architecture and its ability to meet current needs.

Indeed, properly maintaining infrastructure may involve updating it, modernising it or even replacing some of its components.

The fact that a system continues to work does not mean it does not need attention. And waiting until it stops working before acting can turn a planned maintenance task into an urgent, more complex and costly intervention.

The cost of maintenance versus the cost of not maintaining

When a company decides to invest in a new technology, it usually assesses its potential benefits: greater productivity, lower costs, new business opportunities or a better experience for its customers. However, justifying an investment intended to prevent problems can be more difficult.

How do you calculate the value of an incident that never occurs?

This is one of the major challenges of preventive maintenance. When systems work properly, the effort required to keep them operational is barely noticed. By contrast, when a major disruption occurs, its consequences can quickly become apparent.

A service outage can bring operations to a standstill, affect productivity, compromise information security or generate unexpected recovery costs. There is also a less immediate, but equally significant, impact: the loss of trust among customers and users.

This does not mean that every preventive investment is justified, nor that maintenance is always cheaper than repair or replacement. Decisions should take account of risk, the criticality of each system and the resources available.

What matters is incorporating these factors into financial planning, rather than limiting the analysis to the initial cost of acquisition or development.

Because the cost of digital infrastructure does not end when it becomes operational. Its real cost includes its entire lifecycle: operation, maintenance, updates, security and, when the time comes, renewal or replacement.

Innovation and maintenance: two responsibilities that should move forward together

Innovation and maintenance should not be understood as competing priorities. In fact, the further we advance technologically, the greater the need to ensure that the solutions we adopt can continue operating safely, efficiently and reliably.

A new digital platform needs updates and support. Cloud infrastructure requires monitoring and proper management of its resources. Even artificial intelligence-based solutions need oversight, regular assessments and mechanisms to detect errors or changes in their behaviour.

Innovation, therefore, also creates new responsibilities.

An interesting example is the Site Reliability Engineering (SRE) approach, developed by Google, which seeks to balance the evolution of digital services with their reliability. Through practices such as error budgets, teams can decide when to introduce new features and when to prioritise system stability.

This approach reminds us that digital transformation should not be measured solely by the number of technologies we adopt, but also by our ability to manage them over time.

Innovation does not end when we launch something new. It continues throughout its useful life.

Maintaining, updating and improving what we have already built is also part of innovating. Recognising this is essential to developing a truly sustainable technology strategy.

Maintenance needs a strategy too

If we accept that maintenance is part of innovation, we should also incorporate it into organisations’ technology planning. Not as a secondary activity dependent on the available budget, but as an ongoing responsibility.

This means anticipating resources, establishing update policies, monitoring the state of systems and managing the lifecycle of technologies, from implementation to eventual replacement. It also means anticipating needs and assessing risks before they become problems.

But this responsibility should not fall exclusively on technology departments. Although technical teams understand infrastructure needs, decisions about investment, priorities and operational continuity also lie with organisational leadership.

Maintenance is not merely a technical matter. It is also a strategic decision that affects business continuity.

An organisation may have an ambitious digital transformation roadmap, but if it does not consider how to sustain the solutions it adopts, it risks accumulating complexity, costs and dependencies that are difficult to manage.

That is why perhaps we should ask ourselves a question before launching any new technology project: does it make sense to develop a digital transformation strategy without defining how we are going to maintain the technologies we adopt?

Conclusion

We live in a society that celebrates novelty. We are excited to discover new technologies, develop solutions and explore possibilities that until recently seemed unthinkable. And it is positive that this is so, because innovation is one of the drivers of progress.

But perhaps we should also learn to value what does not make headlines: the work of those who keep systems running, prevent incidents, update applications, document processes and ensure that infrastructure continues to meet our needs.

These are tasks that rarely receive the same recognition as a new launch, yet they are essential to sustaining the progress already achieved.

True progress is not only about building the future, but also about looking after what makes our present possible.

Innovation will remain necessary. Maintenance too. The question is not to choose between these two responsibilities, but to find the balance that allows us to move forward without neglecting what we have already built.

And perhaps it is time to ask ourselves: are we investing enough in maintaining what we already have, or are we still waiting for something to fail before giving it the importance it deserves?
