For many companies, experimenting with AI has become the norm.
As CIOs and CTOs plan for 2027, they’re taking a closer look at the technology they already own, what it’s delivering and where it’s worth investing next.
Every company has a few systems that have been around longer than anyone expected. A platform that’s become indispensable. Another that does almost the same thing. An integration that was supposed to be temporary five years ago. And probably a spreadsheet or two doing work an enterprise system was purchased to handle.
That’s how technology stacks evolve. Businesses grow, priorities shift, acquisitions happen and teams find ways to get things done.
As 2027 planning gets underway, those decisions are getting another look.
CIOs and CTOs are balancing modernization, cybersecurity, cloud costs and new technology investments, all while keeping the business running. There’s plenty worth investing in. There’s also value sitting inside technology companies already own.
So what deserves a place in the 2027 tech stack?
More priorities. Same budget conversations.
Technology budgets have always involved trade-offs. Heading into 2027, the list of competing priorities keeps growing.
According to Gartner’s 2027 CIO research, IT budgets are projected to grow an average of 3.7%, while investment in agentic AI is expected to increase significantly.
That puts existing technology spending under a closer lens. Software subscriptions, cloud consumption, maintenance, integrations and support all have a claim on the budget before new initiatives get started.
And the financial considerations extend beyond IT.
RGP’s 2026 CFO Perspectives research found that nearly half of CFOs say their transformation ambitions exceed their organizations’ capacity to deliver.
For technology leaders, that makes the resources required to implement and support investments just as important as the dollars available to fund them.
What’s actually earning its place?
Technology stacks rarely grow according to one master plan.
A department needs a new capability. An acquisition brings another platform. A vendor introduces functionality that overlaps with an existing application. Over time, the environment becomes more complicated to manage.
Flexera’s 2026 IT Priorities Report found that 70% of IT leaders believe business units purchase more cloud and SaaS applications than IT is aware of.
That makes visibility a useful starting point for any technology review.
Which applications are actively used? Where are capabilities duplicated? What does each system cost to maintain, integrate and support? And where are teams still relying on manual workarounds?
Age alone doesn’t tell the full story, either.
An established ERP system may still perform critical functions reliably. A newer platform might offer capabilities that employees have barely touched. And both can become difficult to manage when integrations, customizations or processes add unnecessary complexity.
As RGP explores in When Technical Debt Comes Due, the business impact of technology decisions can extend far beyond IT.
Sometimes modernization means replacing a platform. Other times, it’s improving how existing systems connect, simplifying workflows or making better use of capabilities already available.
The connections matter as much as the platforms
Consider how a customer order moves through an organization.
Sales captures the opportunity in a CRM. Operations manages fulfillment through an ERP. Finance handles billing, and reporting tools bring the information together.
Each platform has a purpose. What happens between them can be just as important.
Are employees reentering information? Reconciling data between systems? Working around integrations that haven’t kept pace with the business?
Those everyday details influence operating costs, employee productivity and how quickly an organization can respond to change.
They also become more important as companies introduce new capabilities.
RGP’s latest CIO/CTO Perspectives research found that 84% of technology leaders expect AI to have a significant impact within two years, yet only 12% feel prepared to scale it.
That readiness gap reflects a broader challenge: technology investments depend on the data, processes, systems and people surrounding them.
Better connections across the enterprise can create value well beyond any single implementation.
Five questions for your 2027 tech stack review
A technology reset can start with a few practical questions:
- Where are we paying for similar capabilities?
Look at overlapping applications, licensing agreements and functionality that may already exist in your current platforms.
- Which systems are becoming harder to maintain or change?
Consider the cost, dependencies and operational impact of aging technology, customizations and integrations.
- Where does work still happen outside the system?
Manual reconciliations, duplicate data entry and spreadsheets can reveal opportunities to improve workflows and integration.
- Are we using what we’ve already purchased?
Review platform adoption, available functionality and vendor roadmaps before making additional investments.
- What would make the biggest difference to the business?
Connect technology decisions to measurable outcomes, whether that’s faster reporting, lower operating costs, better customer experiences or more capacity for growth.
Making room for what’s next
Technology stacks will keep evolving. New capabilities will emerge, business requirements will change and organizations will continue deciding what to build, buy, connect and retire.
The opportunity heading into 2027 is to make those decisions with a clearer picture of the environment as a whole: what it’s costing, how it’s being used and where it’s creating value.
For CIOs and CTOs, a tech stack reset offers a chance to get more intentional about existing investments while creating room for what comes next.
And with so many priorities competing for attention, knowing what deserves the next dollar, the next project and the next hour of your team’s time is a pretty good place to start.
