Most marketing plans fail not from a lack of ideas but from a lack of structure. Teams jump to tactics before understanding the situation, set vague objectives they cannot measure, and forget to define who owns what. SOSTAC — created by PR Smith in the 1990s and refined in his book Marketing Communications — addresses every one of those failure modes with a six-stage loop that keeps planning honest and accountable.
What is SOSTAC?
SOSTAC is an acronym for Situation, Objectives, Strategy, Tactics, Action, Control. PR Smith designed it as a general marketing planning model, but it maps equally well onto digital marketing, content, demand generation, and annual brand plans. Its power lies in sequencing: each stage depends on the one before it, so gaps in your thinking become immediately visible.
The model is deliberately tool-agnostic. Whether you are building a full marketing plan for a SaaS business or a campaign-level plan for a product launch, SOSTAC gives you the same six questions to answer in the same order.
The six stages explained
| Stage | Core question | Key tools & outputs |
|---|---|---|
| Situation | Where are we now? | SWOT, PESTLE, competitor benchmarks, audience research, GA4 / CRM data audit |
| Objectives | Where do we want to be? | SMART goals, OKRs, KPI baselines; see our OKR for marketing guide |
| Strategy | How do we get there? | Segmentation, targeting, positioning (STP); channel mix; value proposition |
| Tactics | Exactly what will we do? | Content calendar, paid media plan, email sequences, SEO roadmap |
| Action | Who does what, by when? | Project plan, RACI, sprint backlog, resource allocation |
| Control | Did it work? | Dashboard, monthly review cadence, A/B test results, budget pacing |
Stage-by-stage breakdown
1. Situation — know your starting point
A rigorous situation analysis prevents plans built on assumptions. Gather quantitative data (organic traffic, conversion rates, pipeline contribution by channel) alongside qualitative insight (customer interviews, sales team feedback). A SWOT analysis structured around data — not hunches — is the standard output. Include a competitor audit: who ranks for your target keywords, what their pricing looks like, and where they are investing in content or paid channels.
2. Objectives — make them measurable
Objectives in SOSTAC must be SMART: Specific, Measurable, Achievable, Relevant, Time-bound. Vague goals like "increase brand awareness" are insufficient. A proper SOSTAC objective reads: "Increase marketing-qualified leads from 320 to 480 per month by Q4 2026, maintaining a cost per MQL below £140." This level of precision makes the Control stage meaningful.
3. Strategy — the "how," not the "what"
Strategy is the most misunderstood stage. Teams often list tactics here — "we will run LinkedIn ads" — when strategy should explain the logic: which segments you are targeting, why, and how you intend to be positioned against competitors. Apply STP thinking: Segmentation (who are the distinct audience groups?), Targeting (which segments offer the best return?), Positioning (what single idea do you want to own in each segment's mind?).
4. Tactics — the specific activities
Tactics bring strategy to life. Map each tactic to the objective it serves: a blog series targeting bottom-of-funnel keywords serves lead generation; a LinkedIn thought-leadership programme serves pipeline acceleration. Avoid the temptation to add tactics simply because they are fashionable. Every tactic should earn its place by connecting upward to Strategy and Objectives.
5. Action — assign ownership
The Action stage is where plans die if skipped. Specify who is responsible, what the deliverable is, what the deadline is, and what budget is assigned. A RACI matrix (Responsible, Accountable, Consulted, Informed) works well for cross-functional teams. If a tactic has no named owner and no deadline, it will not happen.
6. Control — close the loop
Control is not just reporting; it is the mechanism that makes SOSTAC a living plan rather than a static document. Define the cadence (weekly channel dashboards, monthly executive reviews, quarterly strategic reviews) and the process for acting on what you learn. If MQL volume drops below target in month two, what triggers a review of Tactics? Who owns that decision? SOSTAC plans that skip Control revert to the same gaps they were designed to prevent.
Worked B2B example: SaaS HR platform
Consider a mid-market HR software company entering the French market. Here is how SOSTAC structures their planning:
- Situation: Strong UK product-market fit (NPS 42, 94% retention), but zero brand recognition in France. Top three French competitors hold 70% of the market. French HR buyers rely heavily on peer recommendations and analyst reports.
- Objectives: Generate 60 sales-qualified leads from France within 12 months; achieve first-page Google.fr ranking for five target keywords by month 9.
- Strategy: Target mid-market companies (200–2,000 employees) in manufacturing and retail. Position around compliance automation for French labour law — a known pain point competitors address poorly. Primary channel: inbound SEO + partner ecosystem.
- Tactics: Localised content hub (18 articles, 4 guides), French-language LinkedIn campaign targeting HR Directors, integration partnerships with two payroll providers.
- Action: Content lead owns editorial calendar; partnerships manager owns vendor outreach; both report to CMO weekly. Budget: €120k over 12 months.
- Control: Monthly MQL and SQL review vs. target; keyword ranking tracker (weekly); quarterly budget pacing review with ability to reallocate up to 20% between channels.
SOSTAC vs. RACE: choosing the right model
SOSTAC and the RACE framework are complementary rather than competing. SOSTAC is primarily a planning model — it helps you build and structure a plan before execution begins. RACE (Plan, Reach, Act, Convert, Engage) is primarily a customer journey model — it maps marketing activities to the stages a buyer moves through. Many teams use SOSTAC to create the plan and RACE to organise the tactics within it. There is no rule against using both.
Common mistakes to avoid
- Collapsing Strategy and Tactics. Writing "we will do SEO" under Strategy is a tactic, not a strategy. Strategy should explain why SEO, for whom, and against which competitors.
- Skipping the situation audit. Plans built without current data create false confidence. Spend at least two weeks on a proper Situation analysis before writing anything else.
- Orphaned objectives. Every objective must have at least one tactic that directly serves it. If an objective has no corresponding tactic, either the objective is wrong or the tactics are incomplete.
- Treating Control as a reporting afterthought. The Control stage should specify thresholds — not just metrics. "If CPL rises above £200 for two consecutive weeks, we pause paid and reallocate to content" is a Control mechanism. A monthly PDF report is not.
Frequently asked questions
Is SOSTAC only for large organisations?
No. SOSTAC scales from a solo consultant building a 90-day plan to a Fortune 500 marketing department running an annual global strategy. The depth of each stage scales with the complexity of the business; the structure remains the same.
How long should a SOSTAC plan be?
There is no mandated length. A campaign-level SOSTAC plan might fit on 4–6 pages; an annual marketing plan using SOSTAC as its structure might run to 30 pages plus appendices. Clarity matters more than length. Each stage should be long enough to answer its core question and short enough to be read.
How does SOSTAC relate to OKRs?
OKRs fit naturally inside the Objectives stage of SOSTAC. You can express each SOSTAC objective as an OKR: the Objective states the qualitative ambition and the Key Results define the measurable milestones. See our OKR for marketing guide for detail on how to write effective Key Results.
Can I use SOSTAC for a single campaign rather than an annual plan?
Yes, and it works well at campaign level. The Situation stage becomes a brief audience and competitive snapshot; the Objectives stage becomes campaign-specific KPIs (clicks, conversions, pipeline generated); the Control stage becomes a weekly performance review tied to the campaign flight dates.
