Consulting firms like McKinsey, BCG, and Deloitte are rapidly adopting AI tools to enhance efficiency and drive innovation in their operations.

These firms are leading the generative AI trend, helping clients train employees and develop new tools while also testing generative AI applications internally.

The shift towards AI adoption in consulting is viewed as a significant change, promising growth and improved efficiency in the post-pandemic landscape.

McKinsey has introduced an internal AI chatbot named Lilli, which synthesizes over 100 years of intellectual property and is utilized by more than 70% of its 45,000 employees.

Since its launch in 2023, Lilli has become a vital tool for McKinsey employees, who engage with it an average of 17 times per week, saving them approximately 30% of their time.

Lilli's capabilities have expanded to support research, document summarization, data analysis, and brainstorming, contributing to significant time savings for users.

While initial employee reactions to AI were mixed, many now appreciate its ability to save time, enabling them to focus on more complex tasks.

Boston Consulting Group has developed several AI tools, including Deckster, which streamlines the creation of PowerPoint presentations, and has seen employees create over 18,000 custom GPTs for internal tasks.

Deloitte has made substantial investments in AI, launching Zora AI, a suite of specialized agents, and enhancing its digital delivery platform, Ascend, with generative AI features.

Despite concerns about job security due to AI, Deloitte remains optimistic that AI will create new growth opportunities across various industries.

Ernst & Young has also entered the AI space with a chatbot designed to assist consultants with payroll inquiries, improving operational efficiency.

KPMG employs a dual approach to AI, fostering grassroots innovation while developing tools based on employee feedback.
