The dashboard refreshes at 6:47 a.m. Every metric is green. The new software has done exactly what it promised. Files move faster. Reviews close on schedule. Somewhere in a quiet office, a manager stares at the numbers and feels nothing.
Down the hall, a junior auditor sits with a stack of client documents that a machine has already flagged as clean. She reads them anyway. Something about the wording in one paragraph does not sit right. It is not a data point. It is a feeling, the kind no system has learned to name yet.
She raises her hand. She asks a question nobody programmed her to ask.
The tools got faster this year. The judgment call still belongs to a person, and everyone in that building knows it, even if the org chart does not say so yet. The question is who is training that judgment, and whether anyone still believes it is worth the investment.
Meet Karolina Barrett
Karolina Barrett is the Audit & Assurance Change & Adoption Lead at Deloitte in Ireland, and she has spent nearly a decade proving that the hardest part of any technology rollout was never the technology. It was the people expected to trust it, use it, and eventually improve on it. She carries a Master’s degree in Psychology into a world obsessed with software releases, and that single fact explains almost everything else about her.
From the Lecture Hall to the Audit Floor
Karolina’s path did not start in a boardroom. It started at Uniwersytet im. Adama Mickiewicza in Poznan, where she completed a Master’s in Psychology, followed by a postgraduate qualification in Psychological Help in Sexology. It is an unusual foundation for a career that would eventually be measured in project timelines and software adoption rates.
Her first professional role, an IT Content Development Project Coordinator at Skillsoft, looked administrative on paper. She tracked schedules, coordinated global teams, and delivered staff training across Dublin and India. But even then, colleagues noticed something specific. A former teammate later described her as capable, efficient, and, above all, personable, someone who made complicated cross-border work feel manageable for everyone involved.
That combination, structure paired with genuine attentiveness to people, became her signature. When she joined Deloitte in 2016 as an Audit Quality National Office Coordinator, she was handed a portfolio most people would find dry: causal factor analysis, technical consultations databases, liaison work with external regulators. She built systems. She also built trust with the humans who had to use them.
Each role that followed added a layer. As Assistant Project Manager, she managed global
quality milestones and communications strategy. As Project Manager for Audit Quality and Risk, she designed governance structures for data sharing and became the department’s GDPR champion. By 2022, she was leading the deployment of new audit software across Deloitte Ireland, coordinating with Global and European teams, local IT, legal, risk, and operations teams through one of the firm’s largest technical transformations. The programme fundamentally changed how audit professionals across Ireland delivered and documented their work, requiring thousands of behavioural shifts alongside the technology change.
None of it happened by accident. Each step sharpened the same conviction: technology succeeds or fails based on the humans standing next to it.
Where Judgment Meets the Machine
Ask Karolina about artificial intelligence and she does not talk about tools. She talks about people. In her own words, shared after listening to a Deloitte Ireland podcast on AI’s effect on the job market, “The differentiator always will be people, where underlying technology is the same.”
That sentence is not a slogan. It is the operating principle behind everything she does as a Change and Adoption Lead. Her job exists precisely because installing new software is the easy part. Getting thousands of professionals to change how they think, question, and work is the actual transformation, and it cannot be automated.
She has watched entire industries insist that new tools would eliminate the need for expertise, only to see the opposite happen. As she put it, “Spreadsheets didn’t replace accountants. Analytics didn’t replace auditors. AI won’t replace professional judgment.” Each wave of technology, in her view, simply moves professionals further up the value chain, freeing them for interpretation, challenge, and insight rather than replacing the need for those skills.
This belief shows up in how she talks about leadership, too. After facilitating Deloitte’s Global Manager Milestone Programme at Deloitte University EMEA in Paris, she wrote that “The leaders who continue to evolve are rarely the ones with all the answers. They’re the ones willing to keep learning.” It is a quiet rebuke of the command-and-control model many executives were trained on, replaced instead with something closer to curiosity as a leadership discipline.
Her philosophy extends past the audit floor entirely. Alongside co-leads at Deloitte, Karolina helped build the firm’s Menopause Community from the ground up, moving it from a policy conversation into workplace webinars, awareness campaigns, and individual support. Outside Deloitte, she advocates for women navigating pregnancy, breastfeeding, and menopause through her own platform. The connection to her audit work is not obvious until she names it herself: both are about making invisible human experience visible enough for organizations to act on it. A data model cannot flag a colleague quietly withdrawing from meetings. A person, trained to notice, can.
The results back the philosophy. Deloitte’s audit practice recently won Best Use of Technology in Accounting and Finance at the Irish Accountancy Awards, a recognition built on exactly the kind of adoption work Karolina leads: getting powerful new systems into daily use without losing the human oversight that makes them trustworthy in the first place.
The Barrett Playbook: 5 Lessons
Train the judgment, not just the tool. New software fails when people are handed a login and no reason to change how they think.
Treat curiosity as a leadership skill, not a personality trait. The managers who keep learning outperform the ones who already have every answer.
Make the invisible visible. Whether it is a flawed audit file or a colleague struggling silently, the discipline is the same: notice, name it, and act.
Every technology shift moves value upward, not away. Spreadsheets did not erase accountants. AI will not erase professional judgment either.
Build trust before you build systems. Governance structures only work if the people inside them believe someone actually listened to their concerns.
The Question the Machine Cannot Answer
That auditor in the quiet office, the one who read the flagged file anyway, is the answer to the opening scene’s unspoken question. Every dashboard can turn green. Every workflow can run on schedule. None of it means anything without someone willing to ask one more question the system did not think to ask.
Karolina Barrett has spent her career making sure that person exists, is trained, is trusted, and is never made obsolete by the very tools meant to support her.
Karolina Barrett, MA Psychology, Certified Change Management Practitioner,, AgilePM, is the Change & Adoption Lead for Audit & Assurance at Deloitte, based in Greater Dublin, Ireland. She partners with global audit teams to guide technology adoption while co-leading Deloitte’s Menopause Community and advocating for women’s health beyond the workplace.
