Strategy Consulting 101: What the Work Involves and Costs

Strategy consulting is usually sold as an answer. It is better understood as a short, expensive process for reaching one. Strategy consulting is outside help with a company’s largest directional decisions: where to compete, what to buy or sell, and what to stop doing. It is the part of management consulting that works for the chief executive and the board, and it made up 20.7% of European consulting turnover in 2024, by FEACO’s count. In practice you are buying a small team for a few weeks, four to eight by PrepLounge’s account, that ends in a recommendation. Judge it by what that team does in week two, not by the credentials in the proposal.

The fee follows the staffing. RocketBlocks puts a typical strategy case at McKinsey, BCG or Bain at $500,000 to $1.25 million. Boutiques publish no rate cards, so their price is whatever the staffing plan says it is. Below: what the work is, how an engagement runs week by week, who sells it, what each kind of firm charges, and when it is worth buying at all.

The rest of this guide is built on those four numbers and the staffing behind them. Read the week-by-week section before you read a proposal, because it tells you what the fee is supposed to buy.

What Strategy Consulting Is (And Isn’t)

FEACO, the European federation of consulting associations, defines strategy work as helping organisations analyse and redefine their strategies: corporate and business planning, business modelling, market analysis, and strategic advice on major transactions such as acquisitions and listings. It is one of the seven service lines FEACO splits management consulting into, and the one that answers “what should we do?” rather than “how do we do it better?”. A good strategy team brings three things you struggle to generate internally:

1. Pattern recognition across industries. They have usually met your situation before, in another sector, and know which moves worked.
2. Permission to ask uncomfortable questions. No internal politics to navigate, and no career risk in telling the chief executive the growth thesis has a hole in it.
3. Structured synthesis. The ability to turn messy, contradictory inputs into two or three clear choices with evidence behind each one.

What it is not: a substitute for your own judgement. The best strategy engagements end with you making a clearer decision, not the consultant making it for you. If a firm promises to “transform your business”, ask exactly which decisions it will help you make. If it cannot answer, the engagement is poorly scoped. And if you are still unsure whether you need a strategist or a hands-on consultant, our guide to the strategist vs consultant distinction is worth reading before you sign anything.

The Six Types of Strategy Engagement

Type	The question it answers	Who usually buys it
Corporate strategy	Where should the group compete, and how should capital be split across business units?	Chief executive and board
Growth strategy	Where does the next revenue come from: new markets, products, channels or marketing approaches?	Chief executive, commercial lead
Competitive positioning	Where do we win and lose against named rivals, and why?	Chief executive, strategy director
Go-to-market strategy	How do we launch into a new segment, geography or vertical?	Chief executive, commercial lead
Portfolio strategy	Which business units do we build, acquire or divest?	Board, chief financial officer
AI & digital strategy	Where does AI create value in this business, and in what order?	Chief executive, technology lead

The market-sizers carve the work up in much the same way. Fortune Business Insights splits the strategic consulting market into corporate strategy, M&A, economic policy, functional strategy, digital strategy and business model transformation. The length varies less than the labels suggest: PrepLounge puts a typical strategy project at four to eight weeks, whatever the type. Decide which question you are asking before you brief anyone, because the type sets the team.

What Happens in a Strategy Engagement, Week by Week

A strategy engagement is short by design. McKinsey’s strategy work for the UK Department of Health and Social Care in 2020 ran six weeks; BCG’s sector strategy for Puerto Rico’s oversight board in 2023 ran eight. Both contracts are set out in our guide to management consulting fees by project type. RocketBlocks’ worked example of a top-firm case runs twelve. Inside those weeks the rhythm is much the same everywhere. RocketBlocks lists the meetings a case is built around: “kickoff meeting, weekly check-ins, mid-project check in, final presentation”. Here is what should happen between them on a typical six- to eight-week case.

Before week one: the scope. The proposal fixes the question, the team and the fee. Strategy cases are usually priced upfront, RocketBlocks notes, so the scoping conversation is where your money is decided. Some firms sell a short diagnostic first, which they call phase 0: a few weeks spent finding out which question is worth the full fee. The McKinsey contract is a good model of a scoped question. It asked for options on the vision, purpose, end-to-end journeys and organisation of a permanent body to run Test and Trace, in six weeks from 18 May to 26 June 2020.

Weeks one and two: the hypothesis. A kickoff with the chief executive, a data request, and the first round of interviews with your leadership team, your customers and often outside industry experts. A good team works hypothesis-driven, which means it arrives with a view of the likely answer and spends these weeks trying to break it, rather than collecting everything and hoping a pattern emerges. By the end of week two you should be able to state the working answer in one sentence. If the team cannot, the rest of the engagement is research, and you are paying strategy rates for it.

The middle weeks: the workstreams. The case team splits the question into workstreams, each with an owner: the market, the competitors, the economics of each option. Firms like the split to be MECE, mutually exclusive and collectively exhaustive, which in practice means no gaps and no double counting. You see progress at the weekly check-in. At the midpoint the SteerCo, the committee of your executives who sign off each stage, sees the interim findings and kills the options that do not survive them. That meeting is where most of the value sits, because it is the last point at which the question can still change cheaply.

The last fortnight: the “so what”. The analysis becomes a recommendation, written answer first: the decision on page one, the evidence behind it, and the numbers that would change it. It goes to the SteerCo, then to the board.

After the final presentation: the handover, or the next case. Strategy teams generally leave at the recommendation. RocketBlocks describes how firms such as McKinsey, BCG and Accenture design cases that “lead naturally into explorations of next steps (and next cases)”, which the industry calls rolling. There is nothing sinister in it; it is simply how the pyramid stays fed.

Ask for the SteerCo dates in the proposal, and decide who implements before the last fortnight, not after the final presentation.

What Good Deliverables Look Like

The product of a strategy engagement is a recommendation. RocketBlocks puts it bluntly: “The key product is the recommendation itself, not the data assets.” In practice that means a decision memo or a deck with the answer on page one: the two or three choices that matter most, the evidence for each option, and the course of action the team recommends, with its reasons.

You should walk away with:

• A decision framework. Not a recommendation in isolation, but a structured way to weigh the options that your team can reuse.
• Prioritised actions. A sequenced roadmap with owners, dates and the measures each action is meant to move.
• Scenario models. At minimum a base case, an upside case and a downside case, with the assumptions behind each.
• Competitive intelligence. Analysis of your market and rivals that you could not have bought off the shelf.
• An implementation bridge. A clear handover to your execution team, not a deck that gathers dust in a shared drive.

Before the final presentation, ask to see the recommendation in one sentence. If it will not fit, the deck is still looking for it.

Who Does Strategy Consulting: MBB, the Big Four, Boutiques and Independents

Five kinds of firm sell strategy work. What separates them is the staffing plan more than the brains.

MBB. McKinsey, BCG and Bain, known together as MBB, built their names on strategy work for chief executives and boards. Slideworks describes the usual case team as “1+2 or 1+4”: a project leader or engagement manager with two to five consultants and associates, and partners giving oversight part-time. The three sit at the top of Consultancy.uk’s 2025 ranking of strategy consulting firms in the UK.

The Big Four’s strategy arms. Deloitte, PwC, EY and KPMG each run a strategy unit that competes with MBB: Monitor Deloitte, Strategy&, EY-Parthenon and KPMG’s Global Strategy Group. CaseCoach describes them as small, elite units of a few thousand consultants each, and notes that the Big Four entered strategy largely as a way to source other work early in a client’s decision. The structures move. In March 2024 Deloitte announced it would fold consulting, financial advisory and risk advisory into two businesses, and the labels shift with the structures, as our comparison of advisory vs consulting shows.

Mid-tier strategy firms. OC&C, Oliver Wyman, Kearney and L.E.K. follow MBB in the same Consultancy.uk ranking. They sell the same kind of case, often to the same boards, and price below the top three.

Boutiques. Small firms, frequently built around one sector or one kind of question, where the partner who sells the work does much of it.

Independents. Often alumni of the firms above, selling the same methods without the pyramid. On the UK contract market, the median advertised day rate for a Strategy Consultant was £600 in the six months to 28 September 2026, on 17 quoted rates (IT Jobs Watch).

Which of the five you need depends on the size of the decision and on whether your board needs a name it recognises. The next section shows what each one costs.

Pricing Reality: What Strategy Consulting Actually Costs

Every strategy fee is a staffing plan with a margin on top: who is on the team, at what grade, for how many weeks. That is why the range runs from six figures to seven. What a strategic plan, a board offsite or a market entry study costs on the public record, from a $4,400 retreat quote to McKinsey’s $14 million for two university plans, is in our guide to strategy consulting fees.

Who you hire	On the public record	Who does the work
MBB (McKinsey, BCG, Bain)	McKinsey $327.41–$498.23 an hour for analysts and associates, $1,193.57 for a senior partner (US federal schedule, 2024); $500K–$1.25M for a typical strategy case (RocketBlocks); $1.78M cap for eight weeks of BCG work (2023)	An engagement manager and two to five consultants, with a partner part-time
Big Four (Deloitte, PwC, EY, KPMG)	Deloitte up to £2,360 a day on NHS Test and Trace, 2020 (delivery work, not strategy)	Large, mixed teams; strategy sits in separate units
Mid-tier strategy firms (OC&C, Oliver Wyman, Kearney, L.E.K.)	Kearney’s US federal schedule, current to August 2023: $624 an hour for an executive strategy project leader	Case teams led by a partner
Boutique firms	No published rate cards	Senior consultants, often the partners
Independent consultants	£600 UK median contract day rate for a Strategy Consultant, 17 quoted rates (IT Jobs Watch, six months to 28 September 2026)	The person you hired

Boutiques publish no rate cards, so ask for the named rate of everyone on the roster. For hourly rates by industry, our consulting fees by industry guide uses US federal ceiling rates. The middle half of management and strategy rates runs from $129 to $212 an hour, with a median of $166 across 1,470 rates. The Kearney and BCG figures are from the fees-by-project guide linked above. At the small-firm end, Clutch lists an average of $100 to $149 an hour for the business strategy consultants on its platform. The UK figure is what a contractor is paid, not what a firm bills for the same person, and a sample of 17 is directional: the middle 80% of those rates ran from £482 to £835.

The public record behind the top two rows, McKinsey’s federal hourly rates, BCG’s Test and Trace day rates and the NAO’s programme averages, is set out in our guide to Big Four vs MBB consulting fees.

Pay attention to that last column. For most mid-sized businesses the better value is usually a boutique or an independent: you get the senior practitioner doing the thinking, not a junior analyst running the model while the partner sits in another client’s offsite. If you are still deciding between an agency and a consultancy, the delivery model matters as much as the price.

MBB earns its premium in specific situations: when the strategy needs to survive private equity due diligence, when you need global benchmarking data no boutique can reach, or when the McKinsey name itself carries persuasion value with your board. Outside those, you are often paying for the brand more than the brain. Ask every bidder for the staffing plan with a rate per grade, and compare those rather than the totals.

The Right Time to Hire a Strategy Consultant

Strategy consultants earn their fee at decision points, where the cost of getting it wrong dwarfs the consulting bill:

• When a new chief executive arrives. PrepLounge calls it the most common point at which companies hire strategy consultants: the incoming CEO wants a strategic vision for their tenure, usually on a five-year timeline.
• Before a funding round. When you need to stress-test your growth thesis and put a credible plan in front of investors.
• During a market shift. When a regulatory change, a new entrant or a technology shift makes your current strategy uncertain.
• When internal disagreement is blocking progress. An outside team can break a deadlock that politics will not.
• After a competitor makes an unexpected move. When you need rapid scenario planning, not a three-month study.
• Before a major investment. An acquisition, a geographic expansion or a platform migration, where a wrong bet costs far more than the fee.

The wrong time to hire? When you already know the answer and want someone expensive to agree with you. Firms will take that engagement. The fee buys comfort rather than a decision.

If most of your answers landed on the left, write the decision down in one sentence before you speak to a firm. It is the brief.

How AI Is Changing Strategy Consulting in 2026

In January 2026 McKinsey’s global managing partner, Bob Sternfels, told HBR IdeaCast that the firm had “40,000 humans and 20,000 agents”. Data gathering, benchmarking and first-pass market sizing, the work a junior analyst once did with a spreadsheet, is going the same way. That rewrites what a buyer is paying for.

The deliverable is changing

The hundred-page PDF as the final deliverable is on its way out. The firms worth hiring now hand over working models, live dashboards and decision-support tools alongside the strategic narrative. If your consultant still hands over nothing but slides, ask what you are getting that a subscription could not give you.

Pricing models are under pressure

Billable hours made sense when research took weeks. Now that software does the first pass, clients push back on paying partner rates for analyst work. Sternfels told the same interview that “about a third of our revenues total are underwriting outcomes”: fees tied to the client’s results rather than the hours. Capgemini’s chief strategy officer, Fernando Alvarez, put the buyer’s side more simply to Fortune in March 2026: “At the end, people want the cake.” We break down how consulting pricing works in the age of AI.

The human premium is narrowing to judgement

AI synthesises data faster than any analyst. It cannot navigate boardroom politics, read the room at a leadership offsite, or predict which recommendation the chief executive will actually follow through on. Sternfels’ own line is that “there’s not judgment in the model”. What remains worth paying for is judgement: knowing which of three viable strategies fits this leadership team, this culture and this quarter’s reality.

“

AI isn't killing management consulting. It's forcing consultants to prove they're worth more than the algorithms. The ones who can, because they bring judgement, relationships and pattern recognition no model replicates, will thrive. The ones who were basically human search engines? Their clock is ticking.

Ask any firm, large or small, which parts of the work its people will do and which its software will, and whether the fee reflects the difference.

How to Evaluate a Strategy Consultant Before You Sign

Green flags

• They ask more questions than they answer in the first meeting
• They can name specific past engagements in your sector, with outcomes, not just client logos
• They push back on your brief, suggesting a tighter scope or a different framing
• They define success measures before starting and tie the fee to deliverables
• They explain their method without jargon, or translate it when they slip

If a proposal fails more than one of the minimums, send it back before you compare prices.

Measuring ROI on a Strategy Engagement

Most companies never measure what a strategy engagement returned. That is the single biggest reason mediocre consultants stay in business: nobody checks the receipts.

Before the engagement

Define the baseline. ConsultingQuest’s guide to consulting ROI calls failing to set baseline measures at the start one of the most frequent mistakes. Pick the one or two numbers that matter most, whether revenue growth, market share, cost structure or speed to market, and write down where they stand today. Then agree what would make the engagement worth it in twelve months, and have both sides sign it.

During the engagement

Track how fast decisions are being made. A strategy engagement should shorten your decision cycle, not add another layer of analysis. Watch how many of the interim recommendations your team is already acting on. If the answer is few, either the recommendations are impractical or your people were not involved enough in shaping them, and the midpoint SteerCo is the place to say so.

After the engagement

Measure the shift. Did the baseline number move in the direction and by the amount you agreed? Then test the capability transfer: can your team now make similar decisions without calling the consultant back? If you are rehiring for the same kind of question a year later, the first engagement did not build anything internally. It rented someone else’s judgement.

Which One You Need, and How to Tell in the First Meeting

Strip away the brand names and the choice of firm comes down to two things: how large and irreversible the decision is, and whether your board needs a name it recognises. A nine-figure acquisition or a market exit can justify MBB’s weekly team price. A question about which segment to pursue next year usually needs one senior person who has answered it before, and a boutique or an independent will put that person in the room.

One question sorts almost every proposal. Ask the partner: if you had to give us the answer today, what would it be, and what would you need to see by week two to change your mind? A hypothesis-driven team will have a view and a plan to break it. A team that answers with its methodology is planning to spend your first month finding out what the question is. Once you know which kind of firm you need, our guide on how to hire a consultant runs from the brief to the contract.

Frequently Asked Questions

What is strategy consulting?

Strategy consulting is a specialised part of management consulting that helps organisations make high-stakes directional decisions: where to compete, what to invest in, whether to acquire or divest, and how to respond to a market shift. It is one of FEACO’s seven service lines and made up 20.7% of European consulting turnover in 2024. A typical project lasts four to eight weeks, by PrepLounge’s account, and ends in a recommendation, usually delivered as a series of presentations.

What’s involved in a typical strategy consulting engagement?

A scoping conversation and a fixed fee, then a kickoff, interviews and a working hypothesis in the first two weeks. The middle weeks split the question into workstreams, reviewed at weekly check-ins and at a midpoint steering committee. The last fortnight turns the analysis into a recommendation for the board. At the large firms the team is usually an engagement manager with two to five consultants and associates, and a partner part-time (Slideworks).

How much does strategy consulting cost?

On the public record, McKinsey’s 2024 US federal schedule lists $327.41 to $498.23 an hour for analysts and associates and $1,193.57 for a senior partner. On the UK’s NHS Test and Trace programme in 2020, BCG charged £2,400 to £7,360 a day and Deloitte up to £2,360. Boutiques publish no rate cards. RocketBlocks puts a typical strategy case at the top firms at $500,000 to $1.25 million. In the UK, the median contract day rate for a Strategy Consultant was £600 on 17 quoted rates in the six months to 28 September 2026 (IT Jobs Watch), which is what the contractor is paid rather than what a firm bills.

When should I hire a strategy consultant?

At decision points: when a new chief executive arrives, before a funding round, during a market shift, when internal disagreement blocks progress, after a competitor’s unexpected move, or before a major investment. The wrong time is when you already know the answer and want validation.

What’s the difference between strategy consulting and management consulting?

Strategy consulting is a specialised subset of management consulting. Strategy consultants work on direction, mostly for chief executives and boards; management consultants work on how the business runs, across departments, and usually stay through implementation. PrepLounge puts a typical strategy project at four to eight weeks and management consulting at six months to more than a year, and SPI Research’s 2025 benchmark put the average management consulting project at 6.86 months in 2024. For a full breakdown of how these two disciplines differ, see our guide to strategy vs management consulting. If your business is too small for either discipline and needs one person who can do enough of both, that is a business management consultant, and we cover what one does and costs separately.

How is AI changing strategy consulting?

It is taking over the research layer: data gathering, benchmarking, market sizing and first-pass analysis. McKinsey said in January 2026 that it ran 20,000 AI agents alongside 40,000 people, and that about a third of its revenue now underwrites client outcomes rather than billing for hours. The value of the human team is shifting towards judgement, stakeholder management and synthesis, and deliverables are moving from slide decks towards working models.
