Consulting Gets a GenAI Upgrade

Generative AI (GenAI) is transforming consulting, streamlining project execution, reshaping talent needs, and altering business models. Traditionally reliant on manual research and slide-making by large junior teams, consulting firms now see GenAI automate these processes, freeing consultants to focus on higher-value client work.

Faster Research and Analysis

GenAI’s ability to process vast information has cut down research and hypothesis generation from weeks to hours.

A 2023 Harvard Business School and BCG study with 758 consultants found those using GPT-4 completed 12 per cent more tasks, 25 per cent faster, and with 40 per cent higher quality. Yet, performance dipped when AI was used for complex tasks without human oversight, underlining AI as an aid, not a replacement.

Firms like McKinsey now use GenAI tools (for instance, Lilli) for over 500,000 monthly queries, helping consultants focus on insight refinement and client interactions.

Talent and Team Shifts

The traditional consulting “pyramid” model, dependent on large junior teams, is shifting toward leaner hybrid teams blending strategy consultants with AI and tech experts.

Junior consultants now focus earlier on critical thinking, hypothesis testing, and client communication.

Mid- and senior-level consultants require AI literacy, from prompt engineering to bias evaluation.

Firms are hiring fewer generalist MBAs and more data scientists and AI specialists. McKinsey employs over 7,000 digital and tech experts under QuantumBlack and McKinsey Digital.

Changing Business Models

As GenAI reduces timelines, billing purely on hours becomes less viable. Consulting firms are increasingly exploring new pricing structures that better reflect value delivered, rather than time spent. Firms are moving toward:

• Outcome-based pricing tied to client results.
• Subscription-based advisory models with continuous AI insights.
• Productizing in-house AI tools as new revenue streams.

KPMG has a $2 billion partnership with Microsoft to embed AI in audit and advisory, while PwC announced a $1 billion AI investment to integrate GenAI across solutions and operations.

Consultants’ Evolving Role

While GenAI automates research and analysis, consultants’ roles are shifting toward:

• Framing problems for action.
• Interpreting AI outputs within client context.
• Facilitating stakeholder alignment and managing change.
• Ensuring ethical and secure AI deployment.

AI-generated plans still require buy-in from stakeholders and alignment with realities, making the consultant’s human insight indispensable.

Opportunities and Challenges

GenAI offers a powerful toolkit, but its impact depends on how well consultants navigate its possibilities and pitfalls.

Opportunities:

• Faster, higher-quality insights.
• Expansion through proprietary AI tools.
• More strategic client engagements.

Challenges:

• Managing bias and hallucinations in GenAI outputs.
• Ensuring explainability to clients.
• Navigating data privacy and regulatory concerns.

Clients now expect firms to drive transformation, not just analysis, requiring a blend of AI and deep consulting expertise. Consultants must now act as both technologists and change agents to meet rising expectations.

The Road Ahead

With rapid advances, GenAI is no longer optional — it’s foundational to the future of consulting. GenAI will become the default backbone of consulting:

• Routine analysis — automated.
• Strategy design and stakeholder alignment — human-led.
• Business models — moving toward value-based pricing.

AI-first consulting startups are emerging, challenging traditional players with faster, cost-efficient analysis. However, large firms retain an edge in trust, execution, and change management while leveraging GenAI for productivity.

Redefining Value

GenAI is not replacing consultants but amplifying their effectiveness. By automating repetitive tasks, it frees consultants to focus on strategy, enabling change, and aligning stakeholders. In this new landscape, consultants must continuously adapt and upskill, integrating AI seamlessly into their problem-solving frameworks.

As clients adopt AI internally, firms must deliver insightful, practical, and ethical advisory using AI as a tool, not a crutch. The future belongs to those who can blend tech fluency with deep business insight. Consultants who embrace AI while honing human-centric advisory skills will define the next era of strategy consulting, combining GenAI’s scalability with human judgment to drive business results.
