OFP Foresight Lab · Go-to-Market Strategy
Concentrate.
Force when the decisive window opens.
A go-to-market manoeuvre: how a new entrant surrounds an incumbent and takes the market.
Shaka built the chest-and-horns encirclement: the chest fixed the enemy while the horns moved around its flanks, with a reserve held behind. Read as a market manoeuvre, it is how a new entrant moves on an incumbent from several fronts at once, and why the incumbent so often experiences one coordinated attack as three separate crises.
THE STRATEGIST · HE SUBSTITUTED AND HE SUBSUMED
From about 1816, Shaka transformed the Zulu from a small chiefdom into the dominant power across much of present-day KwaZulu-Natal. He ruled until his assassination in 1828.
Centralised regimental power and rapid encirclement. He is widely credited with developing or systematising the "chest and horns" battle formation, in which the chest fixed the enemy while the horns moved around its flanks, with a reserve held behind: a close-combat, disciplined way of fighting that displaced a looser, more ritual one.
He expanded and tightened the existing amabutho age-regiment system, drawing the young men of conquered and allied chiefdoms into regiments serving the king. Each conquest was absorbed into the Zulu state and enlarged the force that fought the next, which is why the wins compounded rather than scattered.

IN MODERN STRATEGY · THE ENCIRCLEMENT
The product attack is only the chest. A new entrant does not move with one competing offer; it moves on the market from multiple fronts at once.
| Formation | In the market |
|---|---|
| Chest · Product Flood | Fix the incumbent at the core proposition. |
| Left horn · Narrative Flood | Shape how the market understands value. |
| Right horn · Access Flood | Expand the routes through which buyers reach you. |
| Reserve · Adaptive capability | Hold capacity back. Read the response. Strike where the defence exposes an opening. |
Move on the market from multiple fronts at once.
Fix attention with Product. Close through Narrative and Access. Hold reserve to exploit the response.
THE FORMATION · HOW THE ENCIRCLEMENT WORKS
The chest fixes. The horns enclose. The reserve waits behind the line.
| Chest | Engages and fixes the opponent in front. |
| Left horn | Moves around one flank. |
| Right horn | Moves around the other flank. |
| Reserve, or loins | Remains behind until needed. |
This is how a new entrant plays the Shaka formation against you: the chest becomes a Product Flood, the left horn a Narrative Flood, the right horn an Access Flood, and the reserve becomes adaptive capability.
THE NEW ENTRANT'S OBJECTIVE
Not every entrant needs the whole field. The objective sets the formation.
Not every entrant needs the whole field. The objective sets the formation.
| Objective | What it means |
|---|---|
| Beachhead capture | Win one defensible entry point. One customer type. One product use case. One geography. One procurement route. |
| Segment capture | Take a defined part of the market. A customer segment, vertical, geography, ticket size or problem category becomes the entrant's territory. |
| Share capture | Take meaningful business away from incumbents across a broader market. The goal is not domination; it is to become a material competitor. |
| Category capture | Own how the market understands the problem. Its language, frameworks, standards or architecture become the reference point. Narrative becomes terrain. |
| Channel and access capture | Control or strongly occupy the routes through which buyers discover, procure or access solutions. You need not own every product if you control how the buyer reaches the market. |
| Full market capture | Become useful across multiple problems, legible in how the market thinks, and reachable through multiple routes, all at once. That is the full encirclement. |
WHAT THE FORMATION MOVES AGAINST · DEMAND AND THE FUNCTION
Everything to this point has been supply-side. The encirclement decides who serves a market, not whether the market is there. Two things sit underneath it, and both are easy to get wrong.
Demand is roughly fixed. You do not create demand. Population and attention grow drip by drip; the want for a thing is mostly already there, met somewhere, at some price. The variable is not how much demand exists but the cost and the boundary of the function that serves it. The entrant's lever is to serve that function better, cheaper, or from inside a different boundary, not to summon new appetite.
Two moves, two objects. What you move against decides which formation you are in. You can substitute the instrument that serves a function, or you can subsume the function itself.
Substitute the instrument
Same function, new tool. Customers move from the old product to the new one.
Digital photography vs film. The photograph stays wanted; the instrument that makes it is swapped. You take the customers off the incumbent product.
Subsume the function
The function itself is pulled inside a cheaper boundary. The old category gives way.
AI vs expensive human cognition. No one out-competes a copywriter on copywriting; the function is absorbed into compute, and the old delivery stops being the unit of competition.
| The axis | Substitute the instrument | Subsume the function |
|---|---|---|
| You move against | A rival product serving the function. | The function itself. |
| What happens | You take the customers off the incumbent product. | You absorb the function into a cheaper boundary; the old category's economics give way. |
| The market | Digital photography against film. | AI against expensive human cognition. |
| The formation | Concentrate, the encirclement (this piece). | Subsume, Dangote. |
Shaka did both. He substituted the method, replacing a looser, more ritual way of fighting with close-combat regimental discipline and the chest-and-horns formation. And he subsumed the people: the young men of conquered chiefdoms were enrolled into the amabutho, the age-regiments of the Zulu state, so each conquest enlarged the force that fought the next. The substitution won the battle; the subsumption made it an empire.
Shaka historiography is contested and partly drawn from colonial-era accounts; the incorporation is cited, not assumed.
THE READINESS GATE
Encirclement multiplies force. It also multiplies what can break.
01 · The product must be battle-ready. Do not launch a Product Flood while the core product is still a prototype or materially unproven. You are about to invite comparison, imitation, scrutiny and response. Ask first: does the product work? Does the value proposition hold? Can customers repeatedly get the promised result? If not, concentration simply exposes weakness faster.
02 · You must be able to weather the response. The first wave will provoke countermoves. Incumbents may cut prices, accelerate product, challenge your narrative, lock relationships or channels, increase marketing, or use capital, reputation or scale against you. Do not begin the manoeuvre unless you have enough runway, capability and strategic optionality to remain standing after they answer.
03 · The window must be open. Shaka is not permanent aggression. Concentration is valuable when a decisive window exists. Move when there is observable temporary advantage: demand is shifting, the incumbent is slow or distracted, a technology transition has opened, buyer behaviour is changing, distribution has loosened, a category is being redefined, or the competitor has visibly exposed a weak position. With no window, three-front movement becomes expensive noise.
04 · You must be able to absorb success. Suppose the manoeuvre works tomorrow. Demand doubles, then doubles again. Can you produce at the same quality, deliver repeatedly, onboard and support customers, finance working capital, and hold service levels while scaling? If not, the entrant creates demand faster than its operating system can absorb it, and the attack succeeds while the company fails.
Product is proven. Delivery is repeatable. Capacity can scale. Runway can absorb retaliation. The window is open.
If not, build first. Hunt later. If overnight success would break your company, you are not ready for full market capture.
HOW THE MANOEUVRE IS PLAYED
01 · Choose the objective. Beachhead, segment, share, category and access, or full market capture.
02 · Pass the readiness gate. Product proven. Delivery repeatable. Capacity scalable. Runway sufficient. Window open.
03 · Launch the first wave. Chest to Product Flood. Left horn to Narrative Flood. Right horn to Access Flood.
04 · Force the incumbent to respond. Their defence reveals what they protect, where they are slow and which capabilities are stretched.
05 · Read the response. The first manoeuvre becomes an intelligence collection layer.
06 · Deploy the reserve. Commit held capability where the response has exposed the opening.
07 · Zig-zag. Do not keep fighting the defended point. Shift pressure to another flank or route.
08 · Repeat while the window remains open.
The formation is coordinated. The response is observed. The next move is more informed than the first.
THE THREE FLOODS
Why three, and why this shape. Envelopment needs two things a single advance cannot supply at once: something to hold the enemy in place, and something to come around it. The chest holds. The horns come around. Three fronts is the smallest number that does both, one to fix and two to flank. With fewer, the enemy is either never fixed, so it moves, resets and slips the attack, or never enveloped, so it is pushed at the front while its routes out stay open. The shape is therefore not three parallel attacks. It is one frontal press and two arcs that close behind the point of contact.
Why product is the chest. The product is what the incumbent is built to defend. Attention, budget, roadmap and management time already sit there, so a move against it is the move the incumbent is certain to answer, and that certainty is the point. The chest does not have to win; it has to fix. While the defender commits to holding the core proposition, it cannot also be everywhere the horns are going. Product is central because it is the most reliable way to pin the defender's centre of gravity for long enough that narrative and access can close around it.
And the chest only fixes if the product is real. A product that does not hold fixes nothing: the defender feels the press, answers it, and the horns close on empty ground. This is why the readiness gate stands first. Product-market fit is not so much a precondition of the manoeuvre as the chest itself.
How the horns move. The chest advances in a straight line, into the defended centre. The horns do not. They move laterally, onto ground the incumbent is not yet defending. The left horn, narrative, moves through the mental terrain, the categories, metrics and definitions by which the market decides what is worth buying. The right horn, access, moves through the material terrain, the partnerships, channels and procurement routes by which buyers actually reach the market. One changes how the buyer thinks; the other changes how the buyer arrives. Neither meets the chest head-on, and both close behind it.
A frontal force the defender must answer, and two enveloping movements onto ground it is not holding, timed to close while the centre is fixed.
| Front | The move | How it fixes you | What it takes to countermove |
|---|---|---|---|
| Chest · Product Flood | Multiple products and value propositions hit your core market at once. | You are forced to respond. Add features. Repackage. Reprice. Accelerate the roadmap. Product, capital and management attention are pulled forward. | Broaden fast enough to match the new surface area, or concentrate around a core product whose superiority, integration or switching cost is hard to dislodge. |
| Left horn · Narrative Flood | The entrant changes the language of the market: categories, frameworks, problem definitions and measures of what "good" looks like. | You must defend not only the product, but the meaning of the product. Leadership has to explain why the existing category still matters. | Reframe the category, simplify the buyer decision around a stronger metric, or accept that the market is evaluating you on someone else's map. |
| Right horn · Access Flood | The entrant expands routes to buyers at once: partnerships, procurement, referrals, strategic introductions and direct channels. | You must defend existing relationships and build new routes, because the attacker is appearing in rooms and pipelines that once belonged to you. | Deepen key relationships, secure longer-term channel arrangements, create new distribution, lock in partnerships or bypass the channels the rival has occupied. |
THE INCUMBENT'S ARMY
The entrant moves as one formation. The incumbent often experiences the same attack as three separate departmental crises.
One manoeuvre, arriving through three doors. If the incumbent cannot join the signals, the formation gains time to close.
| Department | What it reports |
|---|---|
| Sales | Routes, relationships or distribution channels are slipping. |
| Product | A sudden increase in competing offers, features or value propositions. |
| Marketing | The market language is changing and the value proposition is becoming harder to defend. |
Each team sees a different problem. But they are not separate problems. They are the same manoeuvre arriving through three different parts of the organisation. The entrant coordinates the attack; the incumbent has to coordinate the response. If it cannot integrate the signals quickly enough, the formation gains time to close.
THE RESERVE · INFORMED SECOND STRIKE
The first three fronts commit and are watched. The reserve strikes the opening the defence reveals.
The move. The attacker does not commit everything at once. Some capital, talent, product, narrative energy and relationship capacity remain uncommitted.
What the first manoeuvre reveals. The first three fronts force the incumbent to respond. Those responses reveal where the incumbent is strongest, where it is exposed, what it protects first and which capabilities are already stretched.
How it fixes you. You do not know whether the attack you are already defending is the full attack. Your own defence exposes the weak point.
What it takes to countermove. You need reserve capacity of your own: capital, talent, decision speed and optionality not already consumed by defending the first three fronts.
Strike one is a prior, not a bet. Plan as though the first wave might not land. It may succeed outright, but you commit to it as a position taken under uncertainty, not a conviction you must be proved right about. Everything after strike one is adaptive. The first move is there to generate the evidence that directs the second.
Read two fronts, not one. After the first wave, watch two signals at once, and watch them apart. How the incumbent's product reacts is the defence. How the market receives your new product is the demand. They are independent, and the divergence between them is the richest information in the system.
| Incumbent | Market | What it tells you |
|---|---|---|
| Flails | Pulls | The window is real. Press, and release more reserve. |
| Calm | Pulls | Demand the defender has not yet priced. Move before it does. |
| Flails | Shrugs | You provoked a response to something no one wanted. A weak-product tell. Hold the reserve. |
| Quiet | Quiet | No window, or the chest never fixed. Stop. |
One caution on the demand reads. These assume you are substituting within a function the market already pays for. Where the function is not yet cheap or absorbed enough to tip, a cold demand front can mean not yet, not no good. That is the subsume case, and a different discipline: lower the cost of the function and read its boundary, rather than abort.
Release the reserve kidogo kidogo. A second strike committed all at once is a second bet placed before the evidence resolves. Fed in a little at a time, each small release is bought by fresh signal, so you keep learning while you press and never over-commit to a reading that is still forming. The reserve is not held for a knockout. It is held so that being wrong after strike one stays cheap.
The cold market is the live fit test. The demand front checks the one thing the readiness gate could only assume. If the market stays cold while the incumbent reacts, the data is disproving your product-market fit in real time. The discipline is to believe it, and not to feed the reserve into a chest that was hollow.
The first manoeuvre creates pressure. The reserve converts the defender's reaction into intelligence.
THE ZIG-ZAG
The incumbent's response tells you where not to keep fighting.
The zig-zag exists because real markets do not answer where you aim. A clean plan assumes the defender responds to the front you chose; it rarely does. So you do not predict the response, you provoke it, then move to wherever the defence was not. Every defended point is information about where not to keep pushing.
Do not fight the defended point. Reroute the pressure to the undefended flank.
| If they defend | Shift the pressure |
|---|---|
| Product | Do not get trapped in feature-for-feature combat. Advance Narrative or Access. Change how the market defines the problem, or reach the buyer through routes they are not defending. |
| Narrative | Do not spend the whole battle arguing. Advance Product. Ship evidence. Launch capability. Put something concrete in the market that makes the narrative dispute less important. |
| Access | Do not keep pushing against the blocked gate. Open another route: partnership, direct buyer, a different procurement channel, a different geography, a different introduction path. |
First wave creates pressure. Defence creates information. Reserve interprets. Zig-zag reroutes force. The point is not to win every confrontation. It is to keep the formation moving.
THE QUIET WINDOW
The best moment to advance is often when the incumbent's response capacity is temporarily lower than usual.
By the time they regroup, the move is no longer an announcement. It is already terrain.
When response capacity drops. Friday evening. Before a holiday. During an industry conference. During leadership transition. During restructuring. At year-end. During a known budget or planning cycle. Immediately after they commit heavily to defending another flank.
Why it works. The move may land while decision-makers are unavailable, coordination is slower, communications teams are offline, approval chains are dormant, and people assume the field is quiet. By the time they regroup, the move is no longer an announcement. It is already terrain.
Quiet-window timing amplifies a good manoeuvre. It does not rescue a weak one.
THE MANOEUVRE
The manoeuvre, in motion. The chest fixes, the horns close, the reserve drives through the opening.
You look up. The chest held you. The horns closed. You are inside it.
The chest fixes. The horns compress. The defence reveals. The reserve decides where the next force goes.
Attack, observe the response, infer the structure, redeploy the reserve, press the revealed weakness.
You look up. The chest held you. The horns closed. The reserve entered where your defence had already shown the opening. You are inside it. The defender pays the cost of complexity.
HOW AN INCUMBENT BREAKS A SHAKA
Even if you know you are inside a Shaka, most of the good cards are already gone. Recognition does not dissolve the formation. By the time it is visible, the incumbent may already have committed capital, attention and people to the first response. There are still a few cards to play. None are comfortable. Do not defend the perimeter. Break the formation.
Do not fight the horns if you can weaken what is feeding them. Concentrate on the sustaining core.
01 · Counter-concentrate. Strike the attacker's sustaining core. Do not try to match Product, Narrative and Access everywhere. Identify the capability that keeps the formation moving: the core revenue engine, a critical distribution advantage, a scarce capability, a key commercial dependency, a principal product advantage or a source of operating capacity. Concentrate force there. Do not fight the horns if you can weaken what is feeding them.
02 · Deny the terrain. Make what they are capturing worth less. If the entrant is concentrating on a particular profit pool, category or route, change its economics: reprice or commoditise the offer, unbundle the product, open access to something previously scarce, move value into another layer, restructure the proposition, or retreat from an increasingly unattractive segment. Sometimes preserving the company means refusing to preserve the old battlefield.
03 · Refuse fixation. Choose what you will not defend. A Shaka depends partly on making the incumbent treat every pressure point as urgent. Decide deliberately which flank can be temporarily conceded, which segment can be surrendered, which narrative needs no answer, which legacy product no longer deserves capital, and where the business must preserve reserve. Then concentrate where survival or future advantage actually sits. You escape encirclement by becoming willing to leave something behind.
What this requires. Decision speed. Reserve capacity. Strategic clarity. Permission to abandon legacy positions. If every move requires defending the past, the formation has already fixed you.
WHAT MAKES CONQUEST COMPOUND · THE HAND-OFF TO SUBSUME
The encirclement wins the market. It does not, by itself, keep it. A market taken and then left as it was is a raid: the customers can be taken back by the next entrant running this same formation against you. What turns conquest into something that compounds is assimilation, the regimental move. Convert what you capture, the customers, the channels, and the talent and routes taken from the incumbent, into your own expanding system, so each win enlarges the force for the next.
Concentrate takes the market from the incumbent product.
Subsume absorbs the function, until there is less and less left to take back.
