THE END OF THE 100-SLIDE CONSULTING DECK?
AI can produce the analysis. The question is no longer how many slides consultants deliver — but how much impact they leave behind.
As AI compresses analysis from weeks to hours, consulting value is shifting from producing answers to creating decisions, capabilities and outcomes. For decades, the 100-slide PowerPoint deck has been one of management consulting’s most recognisable products. Large teams collected data, interviewed stakeholders, benchmarked competitors, built financial models and gradually distilled weeks — sometimes months — of work into a carefully structured presentation. The deck was more than a communication tool. It was often the visible evidence of the consulting engagement itself. That model is beginning to change.
Artificial intelligence is dramatically reducing the time required to research markets, analyse information, structure hypotheses, synthesise documents and produce presentations. What once required significant teams of analysts can increasingly be accomplished by much smaller teams supported by AI. But the real disruption is not that AI can create PowerPoint slides. It is that slide production was never the real source of consulting value.
FROM INFORMATION SCARCITY TO INFORMATION ABUNDANCE.
Traditional consulting developed in an environment where obtaining and structuring information was expensive. Market intelligence had to be collected. Data had to be cleaned manually. Benchmarks required extensive research. Interviews needed to be conducted and synthesised. Analysts spent considerable time converting findings into structured exhibits and presentations. Clients were therefore partly paying consulting firms for their ability to mobilise intellectual resources at scale. AI fundamentally changes that equation.
Research, synthesis, modelling support and presentation development can now happen at extraordinary speed. Leading consulting firms themselves are deploying proprietary AI platforms to accelerate many of these activities.
As the cost of producing analysis falls, however, another question becomes unavoidable: If everyone can generate analysis faster, where does differentiated consulting value come from? Increasingly, the answer is not more information.
It is better judgement.
THE CONSULTING PYRAMID IS BEING COMPRESSED.
The traditional consulting model was built around leverage. A relatively small number of senior partners supervised larger teams of managers, consultants and analysts. Much of the analytical and presentation workload flowed through the lower levels of that pyramid. AI challenges this structure. Research can be automated. Documents can be synthesised almost instantly. Models can be interrogated conversationally. Draft recommendations can be generated rapidly. Even sophisticated presentations can increasingly be produced from relatively simple instructions. This does not eliminate consultants. But it changes what organisations should expect them to do. The future consulting team may therefore be smaller, more senior and considerably more specialized — combining strategic judgement, sector expertise, technological capability and implementation experience. The question will increasingly shift from: “How many consultants are required?” to: “What expertise is actually required to solve the problem?”
CLIENTS ARE BUYING DECISIONS, NOT SLIDES.
Executives rarely suffer from a shortage of information. They suffer from competing priorities, organizational complexity, uncertainty and difficult decisions.
Should we enter this market?
Should we acquire this company?
How should we redesign the operating model?
Where should we invest?
Which capabilities should remain internal?
What should we stop doing?
These questions cannot be solved simply by producing more slides. They require understanding context, challenging assumptions, recognising weak signals, navigating stakeholder interests and making informed choices despite incomplete information.
That is where experienced advisory work becomes more valuable rather than less. AI may generate twenty strategic options in seconds. Knowing which three deserve serious consideration — and which seventeen should be discarded — is a very different capability.
FROM DELIVERABLES TO OUTCOMES.
The more profound transformation may therefore concern the definition of a consulting deliverable itself. The traditional engagement often followed a familiar sequence:
Analyze → Recommend → Present → Handover
The emerging model is increasingly closer to:
Diagnose → Decide → Design → Implement → Measure → Adapt
This changes what consultants leave behind.
Instead of primarily delivering presentations and recommendations, engagements increasingly need to produce tangible organizational assets: redesigned processes, operating models, decision frameworks, digital tools, implementation roadmaps, capability transfer and measurable performance improvements. The PowerPoint deck does not disappear. Its role changes. It becomes the communication layer around the work rather than the work itself.
THE RETURN OF EXPERTISE.
Paradoxically, AI may make deep expertise more valuable. When information becomes abundant, distinguishing between plausible and genuinely relevant answers becomes harder. This is particularly important in complex sectors such as aerospace, aviation, defence, infrastructure, energy and government, where recommendations cannot be separated from regulation, operational realities, geopolitics, technology, safety considerations and institutional constraints. A sophisticated AI model can analyse thousands of pages of documentation. But experience remains critical in recognising what matters, what is missing, what is unrealistic and what could fail in practice. The consultant of the future therefore competes less on access to information and more on the ability to interpret consequences.
WHAT CHANGES FOR CONSUTING FIRMS?
The implications are significant. Consulting firms will increasingly need to rethink the economics of large pyramidal teams, traditional time-based billing and engagements where substantial effort is devoted to producing documentation. Clients will naturally question why work that previously required weeks should still command the same timelines and economics when AI can accelerate significant parts of the process.
At the same time, expectations will rise. Faster analysis will not necessarily mean cheaper consulting. But it should mean more value delivered within the same period.
The competitive advantage will increasingly belong to firms capable of combining three elements: Technology × Expertise × Execution
Technology provides speed and analytical scale. Expertise provides judgement and context. Execution converts recommendations into results. Remove any one of the three and the model becomes significantly weaker.
THE 20-SLIDE TEST.
There is a simple test that consulting firms — and their clients — may increasingly apply.
Imagine that the final presentation were limited to twenty slides. What would remain? The answer would probably be the elements that mattered most:
the problem;
the evidence;
the strategic choices;
the recommendation;
the risks;
the economics;
and the actions required next.
Everything else would become supporting material, available when required rather than occupying the executive conversation. This does not mean that complex analysis disappears. Quite the opposite. The analytical engine behind those twenty slides may become more sophisticated than ever. But executives should not have to navigate the entire analytical journey simply to understand the destination.
THE END OF THE DECK — OR ITS REINVENTION?
The 100-slide consulting deck is unlikely to disappear completely. Boards will still require evidence. Executives will still need structured arguments. Complex decisions will still require detailed supporting analysis. But the era in which the size of the presentation implicitly demonstrated the depth of the work may be ending. AI is making information cheaper, analysis faster and presentation production increasingly automated. What remains scarce is something different: judgement, experience, trust and the ability to turn insight into action. The consulting firms that understand this transition will not stop producing slides. They will simply stop confusing the deck with the value.
1BHG PERSPECTIVE
The future of consulting is not fewer ideas. It is greater compression between insight and impact. The winning advisory model will combine AI-enabled analytical speed with senior judgement, deep sector expertise and execution capability — delivering fewer pages, faster decisions and more measurable outcomes.
