Unified GTM Strategy - The Definitive Guide

Most companies past their first few quarters of growth already have a go-to-market plan of some kind: a marketing plan, a sales plan, a customer success playbook. The problem is rarely that these plans don't exist. It's that they were each built separately, by a different team, often describing a slightly different customer, a slightly different message, and a slightly different definition of what "winning" actually looks like this quarter.

Left alone, this doesn't announce itself as a crisis. It shows up quietly: a marketing campaign performing well against an audience sales barely engages with, a sales team closing deals that look good on paper and churn within two quarters, a customer success team inheriting expectations nobody in product ever agreed to. Every function can be executing competently and the company can still be running two or three different go-to-market strategies at once, none of them fully visible to the others.

So how do you get marketing, sales, product, and customer success actually pulling in the same direction, using the same facts, instead of four reasonable teams quietly working against each other?

To address this, let's first understand what a unified GTM strategy actually is, and why fragmented go-to-market planning breaks down in the first place.

What is a Unified GTM Strategy?

A unified GTM strategy is a single, shared framework that aligns every customer-facing function, marketing, sales, product, and customer success, around the same market understanding, the same customer definition, and the same growth objective. It is not a plan that sales writes and marketing reads, or a positioning doc that product marketing ships and everyone else interprets loosely. It's the layer underneath all of those documents that makes them consistent with each other.

Most companies already have go-to-market plans. What they don't have is go-to-market coherence. Marketing has a target audience slide. Sales has a territory plan. Customer success has a health-score model. Each of these can be individually well-built and still describe a different company, because nobody checked whether they agree on who the customer actually is, what they actually value, and what "winning" actually means this quarter.

How do you align GTM? You align GTM by building one shared framework, a single ICP, one positioning narrative, and one set of metric definitions, that marketing, sales, and customer success all build from directly. Alignment holds when campaign briefs, qualification criteria, and onboarding all reference that same shared model, and when the model itself gets updated on signal rather than left to drift between planning cycles.

The distinction matters because most GTM failures aren't failures of effort or even of individual strategy quality. A marketing team can build a genuinely sharp campaign. A sales team can be genuinely skilled at closing. A customer success team can be genuinely good at onboarding. None of that guarantees the three are describing, targeting, and serving the same customer. Unification is what makes sure they are.

Why Does a Unified GTM Strategy Matter?

Growth rarely stalls because teams aren't working hard. It stalls because hard-working teams are pointed in different directions, each one optimizing for a version of the customer that's slightly different from the version the team next to them is optimizing for.

Marketing targets one audience while sales is actually closing a different one, because the segment that performs best in paid campaigns isn't necessarily the segment that converts best in a live sales conversation. Product messaging leads with a feature customers don't rank as their top priority, because the message was written before anyone checked which capability actually drives the purchase decision for the accounts that stick around. Customer success inherits accounts that were sold on an outcome the product isn't actually built to deliver yet, and spends the first ninety days managing the gap between what was promised during the sales cycle and what was actually shipped.

None of this shows up as a single dramatic failure. It shows up as a slow tax on every part of the funnel: longer sales cycles because reps are re-explaining a value proposition marketing has already quietly contradicted with a new campaign, rising customer acquisition cost because campaigns and outbound are chasing overlapping but not identical audiences, and soft renewal numbers because the account that closed easily was never a great fit to begin with, a fact nobody discovers until the invoice comes due for renewal.

Quick Stat: In most GTM organizations that later formalize a unified strategy, the single most common finding during the initial ICP alignment exercise is that sales, marketing, and customer success are each working from a materially different written or unwritten definition of the ideal customer, discovered only once someone puts all three answers in the same room at the same time.

Example: A sales team closes a logo that technically fits the ICP on paper, right industry, right headcount, but was sold primarily on a roadmap item that's still six months out. Marketing counts it as a win, since it clears every field in the qualification form. Sales books the commission, since the deal closed at or near list price. Customer success spends the first quarter fielding escalations about a feature that doesn't exist yet, trying to manage a champion who was told, implicitly or explicitly, that the gap would be closed sooner than it will be. The account churns at renewal, having never actually been a good fit for what the product does today, only for what a rep believed the product would do in six months. No single team did anything wrong by the standards of its own function. Nobody was working from the same definition of "good fit," which is precisely the failure a unified GTM strategy exists to prevent.

A unified GTM strategy exists to close that gap: to make sure the account marketing is targeting, the account sales is closing, and the account customer success is expected to retain are, in fact, the same account, described the same way, for the same reasons, by everyone involved.

A second, quieter cost. Beyond the visible symptoms, fragmented GTM planning carries a cost that rarely shows up in a single quarter's numbers: decision fatigue. Every cross-functional disagreement, about which segment to prioritize, which feature to lead with, which accounts deserve the most senior CSM attention, becomes a fresh negotiation, because there's no shared, agreed-upon fact base to settle it against. Leadership ends up re-litigating the same underlying question, "who is our best customer, really", in a dozen different meetings a year, phrased a dozen different ways, because nobody ever wrote down one answer everyone actually uses.

How a Unified GTM Strategy Works

Unification isn't achieved through a single event, a rebrand, a big planning offsite, a new positioning doc. It's a mechanism with three working parts: a small set of shared reference points every function actually builds from, a cadence that keeps those reference points current, and a feedback loop that lets real performance data change the model instead of just confirming it.

One Shared Operating Model, Not One More Document

The mechanism that makes a GTM strategy unified isn't a single big planning document. It's a small number of shared reference points that every function is required to build from, rather than reinvent independently: one ICP definition, one positioning narrative, one view of the competitive landscape, and one shared definition of what a "qualified" customer actually looks like across the entire lifecycle, not just at the point of signing a contract.

When those reference points exist and are actually used, a positioning change made by product marketing automatically updates what sales says on a call, what marketing promises in an ad, and what customer success sets as an expectation during onboarding. When they don't exist, each function updates its own version on its own timeline, and the drift compounds quarter over quarter until nobody can say with confidence what the company's current story even is, let alone whether every team is telling it the same way.

The practical distinction is whether the reference point is a document people are aware of, or an input people's actual workflows are built on. A shared ICP that lives in a slide deck is awareness. A shared ICP that determines campaign targeting parameters, lead-scoring thresholds, and account assignment rules is an input. Only the second version actually unifies anything.

Continuous, Not a Once-a-Year Planning Exercise

Traditional GTM planning tends to be a seasonal event: research happens, a deck gets built, the plan gets presented at a kickoff, and everyone executes against it until the next annual or quarterly planning cycle rolls around. A unified GTM strategy is built to update continuously instead, incorporating market feedback, competitive shifts, and performance data as they arrive rather than waiting for the next scheduled review to catch up with a reality that's already moved.

The seasonal model isn't wrong so much as too slow for how quickly a competitive landscape or a customer's priorities can shift inside a single quarter. A plan set in January that nobody's allowed to touch until the next scheduled review in April means the organization spends up to three months executing against assumptions that might have quietly stopped being true in February.

The Feedback Loop That Actually Holds It Together

A unified GTM strategy isn't just aligned at the start of the quarter. It's designed with a loop: performance data from sales and customer success feeds back into positioning and segmentation, so the shared model gets sharper over time instead of just getting reaffirmed at each review. If a segment sales is closing easily turns out to have a rocky renewal rate, that has to change how marketing prioritizes that segment going forward, not just how customer success staffs it after the fact.

This loop is what separates a unified strategy from a merely aligned kickoff meeting. Alignment achieved once, at a single point in time, decays the moment the market shifts underneath it. A loop that continuously routes real outcomes back into the shared model is what keeps that alignment current instead of becoming a historical snapshot everyone quietly stops trusting.

The Core Components of a Unified GTM Strategy

Most GTM organizations that get this right build around the same six components. The value isn't in any one of them individually, most companies already have some version of each. The value is in whether they're built from the same underlying facts, referenced by every function, and updated together rather than independently.

Market Intelligence

Everything downstream depends on a shared, current read of how the market is actually moving: what customers are prioritizing this quarter versus last, how competitors are positioning themselves, and where the broader category is heading. Without this as a common foundation, teams end up building strategy on assumptions instead of evidence, and different teams, working in different rooms with different inputs, tend to hold different assumptions without ever realizing it. A sales leader's read on the competitive landscape, formed from a handful of recent deals, can differ sharply from a product marketing team's read, formed from analyst reports and public competitor moves, and unless those two views are reconciled into one shared picture, they'll quietly shape two different strategies running in parallel.

Customer Segmentation and ICP

A single definition of the ideal customer, specific enough that marketing, sales, and customer success can all apply it the same way. Not a firmographic filter sitting in a slide that sales quietly ignores because their comp plan rewards closing anything with a pulse and a budget, but a definition that actually determines where marketing spends its budget, what sales prioritizes in a territory, and which accounts customer success staffs with its most senior, most expensive resources. A real, operational ICP changes behavior in all three functions simultaneously. A decorative one changes nothing beyond the slide it's printed on.

Positioning and Messaging

How the company differentiates itself, stated once and used everywhere it needs to be used. When positioning is unified, a prospect hears a consistent story whether they're reading an ad, sitting on a discovery call, or reading the onboarding welcome email three weeks later. When it isn't, prospects notice the seams, sometimes explicitly, asking a rep to clarify why the ad said one thing and the call is now saying another, and reps end up quietly rewriting messaging deal by deal because the official version doesn't hold up under a prospect's direct questions.

Acquisition Strategy

How prospects are identified, engaged, and converted, built from the same segmentation and positioning as everything else in the model, so marketing's definition of a qualified lead and sales's definition of a qualified opportunity are actually the same bar, described in the same language, rather than two different bars that happen to share the same name on a dashboard. This is frequently where the most visible symptom of fragmentation shows up first: a marketing team hitting its lead targets while sales quietly disqualifies a large share of those same leads as poor fits.

Customer Success and Expansion

Retention and expansion strategy built from the same customer understanding used to acquire the account in the first place, so the expectations set during the sales process are the expectations customer success is actually staffed and equipped to deliver on, rather than a gap CS discovers for the first time on an onboarding call, after the contract is already signed and the account already counted as a win.

Measurement and Optimization

A shared view of what's working, using metrics that mean the same thing across every function, so a "win" in marketing's dashboard, a "win" in sales's forecast, and a "healthy account" in customer success's health score are all describing the same underlying reality, rather than three different, quietly incompatible definitions of success that happen to share the same label.

Key Takeaway: None of these six components is exotic. Nearly every company already has a version of all six. What separates a unified GTM strategy from a fragmented one is whether they're built from the same underlying facts and updated together, not whether the components themselves exist.

Benefits of a Unified GTM Strategy

• Better alignment. Every customer-facing function works from the same shared objective, instead of four independently reasonable but mutually inconsistent plans quietly competing for the same market.
• Improved efficiency. Duplicated effort and conflicting priorities drop away: no more marketing campaigns built for an audience sales isn't actually pursuing, no more enablement content built around a positioning angle product marketing has already changed without telling anyone.
• Faster decision-making. Disagreements get resolved against a shared framework instead of turning into a fresh debate, every single time, about whose version of the market is correct.
• A more consistent customer experience. The story a prospect hears in an ad, on a discovery call, and during onboarding stays the same, instead of shifting at every handoff in a way that quietly erodes trust before the relationship has even started.
• Durable, adaptive growth. A market shift, a new competitor, or a pricing change gets absorbed by updating one shared model, instead of requiring four separate teams to each independently rebuild their own version of the plan from scratch, usually at different speeds and with different conclusions.
• Lower CAC over time. When marketing, sales, and customer success are all pursuing the same accounts for the same reasons, acquisition spend stops being split across overlapping-but-not-identical audiences, which tends to show up as a meaningfully lower blended cost per customer within a few quarters.
• Higher forecast confidence. When every function is measuring "qualified," "win," and "healthy account" the same way, a forecast built from that shared data holds up better under scrutiny than one stitched together from three functions' differing definitions.

Real Examples

Two funnels chasing two different companies. A marketing team optimized campaigns around companies with a strong existing DevOps practice, since that's where messaging tested best in paid channels and produced the highest click-through rates. Sales, meanwhile, had the best luck closing companies with no formal DevOps function at all, because the product's simplicity was the actual selling point for that group, and reps had learned to lean into ease of use rather than depth of integration. Neither team was wrong about what converted well within its own channel. But the company was effectively running two go-to-market strategies for two different buyers at the same time, and nobody had decided which one the roadmap, the pricing structure, and the core messaging should actually be built around, which meant every quarter, both teams kept optimizing further away from each other rather than converging.

Positioning that quietly diverged by team. Product marketing updated the core narrative to lead with a new integration six weeks after launch, based on early signal that it was resonating strongly with prospects. Sales enablement, however, didn't get the update folded into the deck rotation for another quarter, partly because the handoff process between product marketing and sales enablement had no explicit owner or deadline attached to it. In the meantime, reps were pitching the old story in live calls, marketing ads were running the new one, and prospects who happened to see both, which was common given how buying committees now research a vendor from multiple angles before ever speaking to a rep, walked into discovery calls visibly confused about which version of the company they were actually talking to, sometimes asking the rep directly to reconcile the two.

A shared definition that changed a quarter's results. A company sat sales, marketing, and customer success leadership in one room and forced a single written definition of "good fit customer," specific enough to include the actual behavioral and firmographic signals that predicted a healthy renewal, not just broad firmographics like company size or industry. Marketing reallocated a meaningful share of spend away from a segment that had looked good on paper, strong initial conversion, healthy deal size, but converted to poor retention once accounts actually went live. The next two quarters showed a smaller but measurably healthier pipeline, and a renewal rate that stopped surprising anyone at the quarterly business review, since the accounts coming through the door now matched the definition CS had been retaining successfully all along.

Customer success inheriting a gap it didn't create. An enterprise deal closed on the strength of a roadmap commitment sales had verbally implied was closer to shipping than it actually was, a common failure mode when sales and product have no shared, explicit agreement on what can and can't be promised during a competitive sales cycle. Customer success spent the first ninety days managing an increasingly frustrated champion instead of driving adoption, since the champion had internally sold the purchase to their own leadership based on a timeline nobody at the vendor had actually committed to in writing. The account renewed, but only at a steep discount, just to keep the relationship alive through the disappointment. The postmortem traced the actual root cause back to sales and product never having agreed, in any documented or enforced way, on what could and couldn't be promised during the sales cycle, a gap a unified strategy's shared measurement and messaging discipline is specifically designed to close.

A fifth pattern worth naming: silent re-segmentation. A company's ICP had been accurate at one point, but a slow shift in the market, buyers increasingly coming from a different sub-industry than the one the original ICP had been built around, went unnoticed for nearly a year because nobody owned checking whether the shared definition still matched reality. Marketing kept targeting the original segment because that's what the shared deck said to target. Sales, closer to live conversations, had already started quietly adapting its qualification instincts to the new reality, without ever updating the shared document. By the time the mismatch surfaced, in a quarterly review that finally compared marketing's targeting criteria against sales's actual closed-won data side by side, the company had spent most of a year with its two largest customer-facing functions working from two different, undocumented pictures of the same market.

Common Mistakes

Treating alignment as a kickoff meeting instead of an operating discipline. Plenty of companies get everyone in a room at the start of the year, agree enthusiastically on a shared narrative, and then let each function drift back to its own version within a quarter, because nothing was actually built to keep the shared model current beyond the goodwill generated in that one meeting.

Confusing a shared slide with a shared framework. A single positioning deck that lives in a shared drive isn't the same as a framework that actually shapes how campaigns get built, how reps qualify a lead, and how CS sets expectations on an onboarding call. If the connection between the document and the daily decisions isn't made explicit, with a real workflow tying one to the other, the document just becomes one more thing everyone nods at in a meeting and quietly ignores the moment they're back at their desk.

Letting comp plans and quotas contradict the strategy. A unified customer definition doesn't survive contact with a sales comp plan that pays out the same commission regardless of whether a deal actually fits the shared ICP. If reps are financially rewarded for closing anything with a pulse and a budget, the shared ICP is decorative, not operational, no matter how carefully it was written or how much leadership buy-in it received at the kickoff.

Reviewing the strategy on a fixed calendar instead of when the market moves. Waiting for the next quarterly business review to update a shared GTM model means operating for months on assumptions the market has already outgrown, which is especially costly in fast-moving categories where a competitor's repositioning or a shift in buyer priorities can meaningfully change what "good fit" or "winning message" actually means well before the next scheduled check-in.

Assuming alignment means agreement on everything. Unified doesn't mean sales, marketing, and CS never disagree, and treating any disagreement as evidence the strategy has failed tends to push teams toward false consensus rather than genuine alignment. It means disagreements get resolved against the same shared facts instead of three different, unexamined sets of assumptions about who the customer actually is.

Building the framework top-down with no input from the teams executing it. A unified strategy designed entirely by leadership, without direct input from the reps, marketers, and CSMs who will actually have to use it daily, tends to produce a technically correct document that nobody on the front line trusts, because it wasn't built from the specific, granular reality those teams deal with every day.

AI and Unified GTM Strategy

AI is changing how fast a shared GTM model can actually stay current. Tools that pull signal from sales calls, support tickets, product usage, and competitive activity can now surface a shift in customer priorities or a positioning gap within days instead of the weeks it used to take a team of analysts to manually synthesize the same picture from scattered sources. That matters directly for unification, because the biggest reason shared models go stale in practice isn't a lack of will, it's that updating them by hand across every affected function is slow, and nobody's explicitly responsible for doing it consistently.

What AI hasn't changed is the harder part: deciding what the shared model should actually say, and getting sales, marketing, and customer success to genuinely build from it instead of quietly defaulting back to their own local version whenever it's inconvenient. A model can flag that messaging performance has shifted, or that a specific segment's win rate is declining, with real precision. It can't decide, on its own, which positioning angle the whole company should commit to, or resolve the disagreement between a sales leader who wants to chase a larger, faster-closing segment and a customer success leader who's watched that exact segment churn at an unsustainable rate. That's still a leadership call, made by people accountable for the outcome, not an output a model can responsibly hand down on its own.

The practical shape of this: AI keeps the underlying intelligence current and surfaces where functions are starting to drift apart from each other, often faster and more consistently than a manual quarterly review ever could. The unification itself, getting every team to actually operate from the same model day to day, still depends on real organizational discipline and an owner with the standing to enforce it when it's inconvenient for a specific function to comply.

Where AI Helps vs. Where It Doesn't: AI is well suited to detecting that drift has started, a positioning update that hasn't propagated, a segment's numbers quietly diverging from the shared plan. It is not well suited, on its own, to deciding what the shared answer should be, or to enforcing that every function actually adopts it. Both of those remain a human, organizational responsibility.

Building a Unified GTM Strategy

Companies trying to unify GTM strategy from a fragmented starting point often try to rebuild everything at once, a new ICP, new positioning, a new measurement framework, all in the same quarter. That's usually too much change to actually stick, since it asks every function to abandon its existing habits simultaneously with no proof yet that the new shared model will actually hold up under real conditions. The more reliable path starts narrower and earns trust incrementally.

1. Start with a single shared definition of the ideal customer, specific enough that marketing, sales, and customer success can each apply it without needing to translate it into their own local interpretation. Get explicit agreement from leadership in all three functions before treating it as final, since a definition sales quietly disagrees with will get ignored the very first time it's inconvenient to follow, usually under quota pressure late in a quarter.

2. Connect it to the moments where drift actually happens: campaign briefs, qualification criteria, and onboarding checklists. A shared ICP that doesn't change how a campaign gets targeted or how a rep qualifies a lead isn't actually operational yet, no matter how well-written the definition itself is.

3. Extend the same discipline to positioning and messaging, making sure the story sales tells on a call, the story marketing runs ads on, and the story customer success uses to set expectations during onboarding are provably the same story, not three versions that happen to sound similar on the surface while diverging in the specific details a sharp prospect will eventually notice.

4. Build in a real review cadence tied to signal, not just the calendar: a meaningful shift in win rate, a competitor's repositioning, a segment's retention numbers moving, any of these should trigger a look at whether the shared model still holds, rather than waiting for the next scheduled planning cycle to catch up with a reality that's already changed.

5. Resist over-engineering the artifact before the discipline exists. A shared one-page ICP and positioning brief that every function actually uses, checks, and references daily is worth more than an elaborate GTM strategy platform nobody has the habit of actually checking. Sophistication in the tooling is not a substitute for the underlying discipline of keeping the model current and enforced.

Key Takeaway: The single highest-leverage first step is almost always the shared ICP, not because it's the most sophisticated component, but because it's the one every other component, positioning, acquisition, measurement, ultimately depends on. Get the ICP genuinely shared and operational before investing heavily anywhere else.

Unified GTM Strategy and the Rest of GTM

A unified GTM strategy doesn't function as a standalone initiative. It's the connective layer that makes several other foundational GTM disciplines actually work together instead of operating as isolated, well-intentioned efforts.

It depends directly on a clearly defined ideal customer profile, since without one, "alignment" has nothing specific to align around, and every function defaults to its own interpretation of who the customer is. It depends just as directly on strong, consistent positioning, since a shared customer definition doesn't help much if the story built around that customer still diverges by team. It connects to GTM execution, since a unified strategy that never gets translated into actual campaign briefs, call scripts, and onboarding workflows remains a well-written document rather than something that changes behavior. And it benefits enormously from a broader GTM operating system, the structural discipline that connects intelligence, strategy, execution, and analytics into one continuous loop, since a unified strategy is, in effect, the strategy layer of that larger system.

Companies sometimes try to build unification without first getting these underlying pieces right individually, attempting to align teams around an ICP that's still vague, or a positioning narrative that hasn't actually been tested against real buyers. Unification amplifies whatever is already true underneath it: a genuinely sharp, well-validated ICP and positioning narrative, once unified across functions, compounds into real efficiency. A vague or untested one, unified across functions, just means everyone is now confidently aligned around the same mistake.

Final Thoughts

Go back to that Series C company running three go-to-market strategies without ever deciding to. That's the default outcome, not an unusual one, whenever every function is left to define the customer, the message, and the win condition on its own, each in good faith, each optimizing for what looks correct from inside its own team. A unified GTM strategy isn't an extra planning document sitting on top of what each team already does. It's the shared foundation, one customer definition, one narrative, one measurement standard, that keeps marketing, sales, and customer success building the same company instead of three plausible but incompatible versions of it.

None of this requires a massive platform or a company-wide reorg to start. It requires deciding, deliberately, that alignment is something a specific person owns and actively maintains, not something that's assumed to happen automatically because everyone involved is reasonably competent at their own job. As markets and buyer expectations keep shifting faster than any annual plan can track, the organizations that treat unification as a continuous discipline, not a kickoff slide, are the ones whose growth compounds instead of quietly working against itself, one reasonable local decision at a time.

Frequently Asked Questions

How do you align GTM?

You align GTM by building one shared framework, a single ICP, one positioning narrative, and one set of metric definitions, that marketing, sales, and customer success all build from directly. Alignment holds when campaign briefs, qualification criteria, and onboarding all reference that same shared model, and when the model itself gets updated on signal rather than left to drift between planning cycles.

How is a unified GTM strategy different from a regular go-to-market plan?

A go-to-market plan is usually built by one function for its own execution, a marketing plan, a sales plan, a launch plan. A unified GTM strategy is the shared layer underneath all of those plans that makes sure they agree on who the customer is, what the message is, and what winning looks like.

Do we need a big cross-functional project to build this?

No. The most durable starting point is small: one shared, specific ICP that sales, marketing, and customer success all agree to use, connected to the moments where drift actually happens, like campaign targeting and lead qualification.

Who should own a unified GTM strategy?

It works best with a single accountable owner, often in RevOps or a GTM strategy function, who has the standing to get sales, marketing, and customer success to actually build from the same model rather than their own local version.

How often should the shared model be updated?

On signal, not just on a calendar. A meaningful shift in win rate, a competitor repositioning, or a segment's retention numbers changing should each trigger a review, rather than waiting for the next quarterly or annual planning cycle.

What's the biggest sign a company's GTM isn't actually unified?

Different functions can each describe the ideal customer, the core message, or what a "good" account looks like, and their answers don't match. That mismatch is usually invisible until someone puts all three answers in the same room.

Can a unified GTM strategy survive a company that's scaling fast?

Yes, but it takes deliberate maintenance. Smaller companies often stay aligned by accident, since there are fewer walls between functions. That informal alignment breaks down as the company adds departments, which is exactly the point where the shared model needs to become an explicit, owned discipline instead of something that used to just happen over lunch.

What's the very first thing to fix if our GTM feels fragmented?

Start with the ICP, not positioning or measurement. Nearly every other symptom of fragmentation, mismatched messaging, inconsistent qualification, expectations CS can't deliver on, traces back to sales, marketing, and CS working from different, undocumented pictures of who the customer actually is.

Does a unified GTM strategy replace the need for individual functional plans?

No. Marketing still needs its own campaign plans, sales still needs its own territory and account plans, and customer success still needs its own playbooks. A unified strategy is the shared layer those individual plans all have to agree with, not a replacement for the plans themselves.
