BCG's North America chair found traditional consultants had 'double the' tech skills he expected. Now the firm trains all staff on AI, betting judgment matters most.
Mel Wolfgang walked into his new role as BCG's North America chair in May expecting a clear headcount. What he found surprised him.
He asked how many of the firm's traditional consultants had skill sets resembling those of BCG's technical hires. The number was higher than expected.
"I've actually kind of got double the workforce that I thought I had, and I started to really categorize what people know," Wolfgang said.
Nearly as many people with traditional consulting backgrounds, the "English lit major with an MBA" as Wolfgang put it, had developed capabilities that approximated those of BCG's specialized technical staff. The firm gauged those skills through tests and employees' demonstrated work on client engagements.
The discovery is reshaping how BCG thinks about hiring and training in an era where AI is becoming central to consulting work. Wolfgang said the firm is accelerating its hiring of both technical talent and business generalists. What he wants, specifically, is the overlap.
"I'm trying to find the Venn diagram overlap of that as much as I possibly can," he said.
That means looking for candidates who combine technical proficiency with the critical thinking BCG has traditionally prized. Many new hires are arriving with a broader range of technical skills already in hand. In interviews, BCG will ask whether candidates have experience using AI tools such as Claude and Codex.
Those abilities only tell part of the story, Wolfgang said.
"You still have to frame the problem. You still have to work the analytics," he said.
Beyond that, consultants need to determine whether an AI generated answer makes sense. That, Wolfgang said, is where the craft comes in.
"The role of judgment has increased enormously, and that's an apprenticed skill," he said.
Senior staff spend time with junior consultants to help them arrive at the best answers, Wolfgang said. AI can generate insights, he noted, but "you might have to do it multiple times because what it spits out originally may require a lot of refinement and judgment."
About 30% to 40% of BCG's work now focuses on AI, Wolfgang said, including helping clients reshape their business models around the technology. The rest falls under traditional consulting, things like strategy, mergers, and post-merger integrations. Yet those engagements also generally involve AI in some way.
"Pretty close to 100% of our work today talks about AI in some way," he said.
To keep pace with client demand, BCG has expanded employee training well beyond what it provides to new hires or those entering a new client industry. The firm instructs staff, from consultants to support and operations teams, on topics such as building AI agents and determining where best to use them. For employees who want to go deeper, the company offers instruction in data engineering and other technical areas.
The AI fluency training, structured as a four step ladder, involves technical tasks such as programming an AI tool that employs multiple agents. It also forces participants to think through judgment calls.
"They also spend a lot of time forcing you to think through the judgment," Wolfgang said of the lessons.
The training requires passing a series of assessments. Those tests adapt to help staffers who might be struggling, Wolfgang said.
"If you're not doing well, it adapts the questions until eventually you learn it," he said.
About half of BCG's North American workers have completed the first level of AI training, Wolfgang said. About one third have finished the second, and about 20% the third. The firm's goal is to have all staff finish the first level by the end of the year and all four levels in the next couple of years.
Wolfgang, who said he recently completed his second training tier, wants staffers to pause between steps and apply what they have learned. He compared it to passing the written test for a driver's license.
"Now you've got to go pass your driver's test, and that happens on the casework," he said.
The AI instruction on its own is only part of the equation, Wolfgang said.
"The critical thinking that a consultant has always delivered is still in the bull's-eye of what we need to train people to do," he said.
