PwC’s appointment of Dan Priest as its first U.S. Chief AI Officer on July 16, 2024, reflected a central challenge of workplace AI: buying tools is easier than deciding how people should use them, how their work should change, and who remains accountable for the results. PwC’s message was that AI is not just an IT project. Its benefits and risks reach employees, managers, clients, and the business itself.
PwC’s 2024 workforce effort emphasized broad AI literacy and responsible use. By 2026, the firm’s public position had widened toward redesigning roles and workflows and governing human-AI collaboration, including agentic systems. The reported adoption figures offer signals of scale, but they do not independently establish productivity or financial returns.

Why PwC appointed a Chief AI Officer
PwC US named Dan Priest its first Chief AI Officer on July 16, 2024. The appointment advanced the firm’s announced three-year, $1 billion investment in AI capabilities. The role was intended to connect AI strategy and transformation across the business, not simply to select technology. PwC’s appointment announcement describes the investment and the new position.
The distinction matters: an organization can have excellent technology leaders and still lack a clear way to prioritize AI opportunities, change business processes, prepare its workforce, and manage risk across departments. A CAIO can coordinate those decisions, but the title does not automatically transfer every AI responsibility to one person.
#1 Best Overall
Priest’s appointment was specifically for PwC US. It should not be read as a statement that the global PwC network has only one AI leader or that every organization needs an equivalent executive title.
What the CAIO coordinates—and what remains shared
AI strategy crosses established leadership boundaries. The CAIO can help align business goals, technical architecture, workforce plans, and responsible-AI controls, while functional leaders retain accountability within their areas.
| Leader or function | Typical responsibility in an AI program |
|---|---|
| CAIO | Coordinate AI strategy, portfolio priorities, adoption, and transformation across functions; connect investment to measurable business outcomes. |
| CIO or CTO | Technology platforms, systems integration, data and architecture, reliability, and technical delivery. |
| CISO and security teams | Security controls, access, threat management, and incident response. |
| Legal, privacy, and responsible-AI leaders | Applicable obligations, privacy, risk assessment, model and use-case controls, and oversight. |
| CHRO and learning leaders | Workforce planning, role changes, skills development, employee communications, and change support. |
| Business-unit leaders | Use-case selection, workflow ownership, service quality, and results in their operations. |
The exact division varies by organization. PwC partner Jennifer Kosar has noted that CAIO-like work may already be performed by a CIO, CTO, CISO, or another executive, even when it is not a full-time role. A dedicated CAIO is a governance choice, not a universal requirement. Computerworld’s overview of the CAIO role provides that broader context.

Priest’s mandate: connect strategy, technology, people, and risk
In his Computerworld interview, Priest described a broad agenda rather than a narrow technology remit. It included assessing AI’s effects across business functions, adapting strategy, activating employees, changing architecture and operating models, and embedding responsible use. The interview with Priest and PwC’s Yolanda Seals-Coffield is the source for these priorities.
1. Assess business impact
AI may reduce the time required for some tasks, change the cost of delivering a service, or create new products and revenue opportunities. Leaders need to examine each function’s work rather than assume a general-purpose tool will have the same effect everywhere.
2. Revisit business strategy
Faster or cheaper work can change how a company competes, prices, serves customers, and creates products. A technology deployment without a plan for those consequences may improve a local task without changing business performance.
3. Prepare and activate people
Employees need approved tools, practical training, clear expectations, and opportunities to apply what they learn. Leaders also need to explain how tasks and roles may evolve, rather than treating training as a one-time announcement.

AI rarely works as a standalone chatbot bolted onto an unchanged business. Data access, applications, workflow handoffs, decision rights, review procedures, and support models may all need to change.
5. Make responsible use operational
Governance must address risks throughout an AI use case’s lifecycle: what it is used for, what information it can access, how its output is checked, who can act on it, and how failures are detected and handled.
What it means for workers to know their role with AI
“AI literacy” does not mean every employee must learn to build a model. Most workers need enough understanding to use approved systems appropriately, judge their limits, and know when a human decision or escalation is required. The practical responsibilities depend on the job, the tool, and the consequences of an error.
- Know which AI tools are approved for the work and which information may not be entered into them.
- Check generated content for accuracy, completeness, bias, and fit for the task; do not assume fluent language means reliable evidence.
- Understand who is accountable for the final decision, especially in client-facing or consequential work.
- Follow requirements for documenting AI assistance or disclosing its use when applicable.
- Know how to correct, reject, or escalate an output that appears unsafe, unsupported, or wrong.
- Understand which tasks AI may assist with and how the surrounding workflow, review, and performance expectations are changing.
Human oversight is meaningful only when the reviewer has the time, expertise, access to relevant evidence, and authority to stop or correct the process. A worker asked to approve an AI result without those conditions can become a rubber stamp rather than a safeguard.

PwC’s My AI program was aimed at approximately 75,000 people in its U.S. workforce. The firm described a mix of online courses, videos, podcasts, in-person instruction, gamified learning, prompting events, hackathons, leadership material, and responsible-AI instruction. Its public account includes foundational material for nontechnical employees as well as separate content for business leaders. PwC’s account of its generative-AI program describes the initiative and reported participation.
PwC said 95% of its U.S. employees participated in My AI and that employees voluntarily contributed more than 360,000 hours to AI skills development. Those company-reported figures indicate reach and time devoted to learning; participation alone does not establish that every employee mastered the material or changed a work process successfully.
The program’s useful progression is from basic familiarity to applied work: first explain how the technology works and how to use it safely, then help teams redesign everyday tasks around it. Prompting lessons cannot, by themselves, change a workflow, define a review standard, or clarify who owns an outcome. Broad foundational training is most useful when paired with role-specific practice and support from the people who own the work.
Tools were one part of PwC’s approach
PwC described using ChatPwC, an internal generative-AI tool integrated with Azure OpenAI services, as well as ChatGPT Enterprise. Its wider technology relationships and enterprise applications included Microsoft, AWS, Anthropic, Google, Meta, Adobe, Oracle, Salesforce, SAP, and Workday. PwC and OpenAI also announced an arrangement involving ChatGPT Enterprise adoption by the U.S. and U.K. firms and PwC’s role as an OpenAI reseller. The PwC–OpenAI announcement describes that arrangement.
These examples do not amount to a universal recommended software stack. Tool access is only one input: organizations still need appropriate permissions, data protections, employee training, output review, and a business process in which the technology has a defined job.

What PwC’s productivity figures do—and do not—show
The available figures describe different things: employees’ reported efficiency observations, participation in learning, and tool activity or capacity. They should not be combined into a single claim that AI has produced a particular net gain in productivity or profit.
| PwC-reported figure | What it indicates | What it does not establish on its own |
|---|---|---|
| Regular users of PwC’s generative-AI tools observed 20%–30% efficiency gains, as reported in the Computerworld interview. | An internal observation attributed to regular users. | An independently audited productivity result, a workforce-wide average, or a quality-adjusted net gain. |
| 95% of PwC U.S. employees participated in My AI; employees voluntarily devoted more than 360,000 hours to AI skills development, according to PwC. | Reported reach and learning time for the program. | Mastery, sustained use, or improved business outcomes for every participant. |
| PwC said employees made more than 20 million Microsoft Copilot actions in April 2026 and freed more than one million hours of capacity. | Company-reported activity and capacity for that month. | That the hours became lower costs or additional revenue, or that the figures account for review, rework, quality, and risk. |
The 20%–30% observation comes from Computerworld’s interview; the participation and learning figures are on PwC’s My AI page; and the Copilot figures are in PwC’s Microsoft Copilot case study. They are company-reported metrics, not independent validation of ROI.
For a clearer view of value, organizations can track task cycle time after review and rework, error and correction rates, service quality, customer outcomes, security incidents, employee workload, and whether time released is actually redirected to higher-value work. Logins, prompts, generated drafts, and nominal hours freed are activity measures; they are not substitutes for those outcomes.
Responsible AI needs controls across the work, not only a policy
PwC’s stated approach emphasizes ownership, risk and value assessment, validation, ongoing monitoring, and human oversight. A lifecycle view makes those principles more concrete for employees and managers:
| Stage | Operational question |
|---|---|
| Select the use case | What business value is expected, what could go wrong, and who owns the process? |
| Prepare information | Is the data permitted, appropriately protected, accurate, and suitable for this use? |
| Generate output | Is the tool approved, and is the activity handled through the required workflow? |
| Review | Who checks accuracy, bias, completeness, and relevance, and what evidence can they inspect? |
| Decide | Which decisions require an accountable human, and does that person have authority to disagree? |
| Deliver | Are confidentiality, professional obligations, and any applicable disclosure requirements met? |
| Monitor | Who tracks errors, drift, complaints, incidents, and changes to the model or vendor service? |
| Improve or stop | What triggers a workflow change, tighter controls, restricted use, or retirement? |
Common failure modes include employees putting confidential or personal information into unapproved services; hallucinated legal, tax, audit, or financial content; biased recommendations; undocumented sources; and reviewers accepting outputs without scrutiny. Controls can also fail when no one owns monitoring, a vendor or model update changes results unnoticed, or AI creates extra review work that is not counted. Training should cover judgment and escalation, not only prompt technique.
How PwC’s public focus evolved by 2026
PwC’s 2024 message stressed enterprise adoption, workforce AI skills, and responsible use. Its public material by August 2026 put more emphasis on changing work itself: redesigning roles, teams, and operating models; embedding AI in workflows; and planning for collaboration between people and increasingly capable systems. A July 2026 article co-authored by Priest argued that AI programs can stall when they concentrate on technology and neglect work and workforce change. The workforce-transformation article sets out that position, while PwC’s future-of-work page describes its broader workforce framing.
The shift also raises a distinction between a tool that drafts or summarizes and an agent that can take actions across systems. Agentic workflows need clearly bounded permissions, approval gates for consequential actions, audit logs, exception handling, and a way for a person to take over or reverse an action where possible. PwC’s 2026 Copilot figures are a deployment example, not proof that all agentic systems are safe or that the same design will suit every organization.

- Name an executive accountable for coordinating AI strategy; use a dedicated CAIO only if the scope, authority, and portfolio justify it.
- Inventory AI use cases and assign a business owner to each one.
- Classify use by risk and define which data and tools are permitted.
- Set review, escalation, incident-response, and documentation expectations before broad rollout.
- Provide a common foundation for all employees, then add role-specific practice for the workflows that will actually change.
- Give reviewers sufficient expertise, time, source evidence, and authority to reject an output.
- Measure quality-adjusted outcomes, not just tool usage or time claimed as freed.
- Revisit roles, incentives, workload, and performance measures as processes change; involve workforce leaders in that redesign.
For small organizations or teams with limited AI use, a named owner and a usable escalation process may be more effective than creating a new executive post. In regulated or client-facing work, documented controls and review are particularly important. When AI changes job expectations or performance monitoring, employees need clarity about what is changing, how their work will be assessed, and how to raise concerns about unsafe uses.
