2026 GBS Key Issues Study shows AI delivering measurable gains across customer experience, service quality and employee engagement as organizations race to close a record efficiency gap
The Hackett Group, Inc. (NASDAQ: HCKT), a leading Gen AI consultancy and enterprise digital transformation firm, today announced findings from its 2026 Global Business Services (GBS) Key Issues Study, showing that GBS organizations are accelerating AI adoption to counter unprecedented productivity pressure, with early deployments already delivering measurable gains in service quality, customer experience, and employee engagement.
The study finds the GBS workload is forecast to grow by 15% in 2026, outpacing projected staffing growth of 10% and budget increases of just 7%. This creates a 5% productivity gap and an 8% efficiency gap – the most significant imbalance GBS leaders have faced in years. In response, organizations are deploying Gen AI and automation as strategic transformation engines to reimagine how work is structured and delivered – not incremental productivity enhancement tools.
“Facing this kind of pressure, the organizations that will come out ahead are those that move beyond adopting AI as a surface-level add-on and instead use it to fundamentally reimagine how work gets done – combining digital innovation with operational resilience,” said Martijn Geerling, Europe Applied Intelligence practice leader and GBS Applied Intelligence program leader at The Hackett Group®.
AI delivers broader value than cost savings alone
AI is already transforming GBS operations. Nearly 90% of GBS leaders report that AI is reshaping routine tasks, and more than half see measurable effects on complex work. Early Gen AI deployments are delivering a 13% improvement in customer experience, 11% gains in both employee engagement and service quality, and a 10% productivity boost. Cost reduction and full-time equivalent (FTE) savings have been more modest, reinforcing that AI’s primary value lies in elevating service performance rather than simply reducing expenses.
One-quarter of GBS organizations expect broad deployment in 2026, up from under 10% a year ago. Customer service leads with 32% planning wide-scale deployment, followed by information technology at 25% and supply chain at 21%. In established GBS domains – finance, procurement and human resources – 13% to 18% are preparing for broad rollout, and a majority are actively piloting or selectively deploying AI.
As Gen AI adoption expands, outsourcing relationships are also evolving from labor arbitrage to AI-enabled digital transformation partnerships. Business process outsourcing (BPO) providers are embedding AI into service delivery to transform manual labor to digital labor, improving experience, quality and workforce effectiveness. Increasingly, organizations are seeking partners that can deliver AI-enabled solutions rather than simply lower-cost labor. For GBS leaders, these partnerships can provide another option to accelerate the shift from manual labor to digital labor while accessing AI capabilities and investment scale that would be challenging to replicate internally.
Closing the AI execution gap in GBS
Even as AI adoption accelerates, confidence in achieving core GBS objectives is declining. While 70% of GBS leaders rank cost leadership as a top priority and 69% prioritize value creation, only 30% now express high confidence in meeting cost reduction targets (down from 44% last year), and just 21% are highly confident in achieving value creation goals (down from 41% last year). Rising workloads, constrained budgets, and uncertainty around how to operationalize AI execution are widening the gap between ambition and outcomes.
Execution discipline, rather than strategic intent, is now the primary challenge. Nearly three-quarters (72%) of leaders cite misalignment between expected and actual AI benefits as a significant concern – tied with process complexity and technology immaturity. However, concerns around data privacy, regulatory issues and ethics have declined in priority, signaling a shift from whether to adopt to how to deploy it effectively.
For leading GBS organizations, the opportunity lies in moving beyond experimentation to process-level transformation supported by clear business cases. By combining process intelligence, benchmarking and targeted AI deployment, organizations can identify where automation and digital labor deliver the greatest productivity and service improvement.
To accelerate progress in 2026, GBS leaders are focused on five priorities: expand automation into higher-value and complex activities; build digital skills and capabilities; align cost optimization with value creation; strengthen data integrity and governance; and redefine performance management to include customer experience, employee engagement, service quality and innovation alongside traditional cost metrics.
“AI and automation are becoming foundational to GBS performance,” said Amar Changulani, research director at The Hackett Group®. “Organizations that focus on process-level opportunities and deploy AI with clear, fact-based business cases are already seeing measurable gains in productivity, service quality, and customer experience – and that performance gap will continue to widen.”
