SOSTAC is a six-stage marketing planning model created by the UK marketer PR Smith in the 1990s. The letters stand for Situation, Objectives, Strategy, Tactics, Action and Control. Each stage answers one question, from where are we now to how do we know we are getting there, so a team can plan a campaign or a year the same way.

Key takeaways

  • SOSTAC stands for Situation, Objectives, Strategy, Tactics, Action and Control, and was created by PR Smith in the 1990s.
  • The model separates strategy, the route to the objectives, from tactics, the marketing mix that carries it out.
  • Situation and Control are the evidence stages, and most weak plans are thin on both.
  • PR Smith wrote for the Chartered Institute of Marketing in September 2025 that any AI-generated plan should be treated as a first draft only.
  • The same six stages work for a one-page campaign plan and for an annual marketing plan.

What is SOSTAC?

SOSTAC is a planning checklist in the order you should think. PR Smith’s own summary gives each stage a question, and the model is popular because those questions stop a team jumping straight to tactics, which is where most marketing conversations start. The digital marketing author Dave Chaffey notes that it was rated among the most popular marketing models in a poll of marketers run by the Chartered Institute of Marketing.

StageQuestion it answersWhat goes in itCommon mistake
SituationWhere are we now?Customers, competitors, performance, strengths and weaknessesA data dump with no conclusions
ObjectivesWhere do we want to be?Measurable goals with dates, tied to business resultsActivity goals such as “post three times a week”
StrategyHow do we get there?Target audience, positioning, channel choices, partnersA list of tactics called a strategy
TacticsWhat exactly will we do?The marketing mix, campaigns, content, pricing, channelsTactics that don’t trace back to the strategy
ActionWho does what, when?Owners, timelines, budgets, briefs, processesNo named owner for each piece
ControlAre we getting there?Measures, reporting rhythm, review pointsMeasuring what’s easy instead of what the objective needs

Where are we now?

Situation analysis is the evidence base for everything after it. It covers your customers and what they want, your competitors and how they position themselves, your own results against last year’s objectives, and the strengths and weaknesses that matter to the next twelve months.

The test of a good situation analysis is that it ends in conclusions. Five pages of charts with no “so what” leave the team to guess which facts matter. Three or four clear findings, each with its evidence, give the objectives something to stand on. The positioning audit pipeline and Category Entry Point research playbooks both produce situation evidence a team can plan from.

How do objectives differ from goals?

In SOSTAC the objectives say where you want to be, and PR Smith recommends SMART objectives, specific, measurable, achievable, relevant and time-bound. The useful discipline is to tie them to business results. “Grow online revenue from new customers by 15% by next September” gives the plan a target. “Increase brand awareness” doesn’t, because nobody can tell whether it was met.

Good plans also separate the business objective from the marketing objectives that serve it. Revenue is the business objective. New customer numbers, conversion rate or repeat purchase rate are marketing objectives that drive it.

How do strategy and tactics differ?

Strategy is the route. It says who you will target, how you will position the brand against competitors, which channels carry the plan and which partners you will work with. Tactics are the details of that route, the marketing mix of specific products, prices, places and promotions.

The two blur in most plans, and the cost is real. A list of channels and campaigns labelled “strategy” gives no basis for saying no to anything. One way to check is to ask whether the item would still be true if every campaign changed. “Win cyclists who train indoors through the winter, through coaches and clubs rather than paid social” survives a change of campaign, so it is strategy. “Run a January Strava challenge” is a tactic that serves it.

The Basics piece on strategy, campaigns, creative and execution goes further into where each word starts and stops, and the channel choices inside a strategy are covered in owned, paid and earned media explained and above the line vs below the line.

What goes in Action and Control?

Action turns tactics into work. It names an owner for each piece, sets the timeline, allocates the budget and covers the processes and briefs that get work out of the door. PR Smith’s description of the stage centres on making sure the tactics are carried out well, which in practice means the boring operational detail most plans skip.

Control says how you will know whether it’s working. It sets the measures for each objective, the reporting rhythm and the review points where the team decides what to change. A plan without Control can’t learn, so the same mistakes reappear the following year. The attribution tear-down playbook helps here, because it tests whether the numbers in your dashboard reflect what actually drove results.

How does AI change SOSTAC?

PR Smith addressed this himself in a September 2025 article for the CIM, alongside an AI edition of his SOSTAC guide. He named situation analysis, strategy, tactics and actions as stages where AI is especially relevant, and advised treating any AI-generated plan as a first draft only.

Mapped to the three layers of AI, the split looks like this.

StageWhere AI helpsWhat stays with a person
SituationPulling and summarising data, competitor reviews, research synthesisDeciding which findings matter
ObjectivesModelling what different targets would requireChoosing the targets and owning them
StrategyStress-testing options and spotting gapsThe choice of audience and position
TacticsDrafting campaign ideas, content plans and briefsPicking which ideas to back
ActionBuilding timelines, briefs and recurring reportsAccountability for delivery
ControlWeekly reporting and anomaly checksDeciding what to change

Our view at Manual Focus is that AI makes SOSTAC more useful, not less, because it removes the hours that once made a thorough situation analysis and a proper control loop too expensive for most teams. The quarterly planning ritual playbook shows how to run that loop every quarter rather than once a year.

How to use SOSTAC on one page

For a single campaign, give each stage two or three lines. State the situation finding the campaign responds to, the one objective it serves, the audience and position, the main activity, the owner and date, and the single number you will judge it by. If any stage is blank, the campaign isn’t ready to brief.

Frequently asked questions

What does SOSTAC stand for?

SOSTAC stands for Situation, Objectives, Strategy, Tactics, Action and Control. It is a marketing planning model created by the UK marketer PR Smith in the 1990s. Each stage answers one question, from where are we now, through where do we want to be and how do we get there, to how do we know we are getting there.

Is SOSTAC still relevant with AI?

Yes. PR Smith published an AI edition of his SOSTAC guide in 2025 and wrote for the Chartered Institute of Marketing that any AI-generated plan should be treated as a first draft only. AI speeds up situation analysis, tactics and action planning, but choosing objectives and strategy still needs human judgement.

What is the difference between strategy and tactics in SOSTAC?

In SOSTAC, strategy is the overall route to the objectives, covering who you target, how you position the brand and which channels carry the plan. Tactics are the details of that strategy, the marketing mix of specific campaigns, prices, content and channel activity. A useful test is that strategy rarely changes within a year, while tactics change often.

How long should a SOSTAC plan be?

A SOSTAC plan should be as long as the decisions need and no longer. For a single campaign it can fit on one page, with a few lines per stage. For an annual marketing plan the situation analysis and control sections usually take most of the space, because they hold the evidence and the measures.

From the podcast

A Manual Focus Basics episode. James and Hannah walk through SOSTAC, the six-stage planning model PR Smith created in the 1990s: Situation, Objectives, Strategy, Tactics, Action and Control. They cover what each stage answers, how to tell strategy from tactics, why most plans fail in the Action stage, and why Control is where a plan gets updated rather than scored. Hannah brings in PR Smith’s own 2025 advice on AI and SOSTAC, that any AI-generated plan is a first draft only, and they map the stages onto the three layers of AI.

Get AI on this

Paste these into whichever AI assistant you use: ChatGPT, Claude, Gemini or Copilot. Swap the bracketed parts for your own details. The first needs an assistant that can open web pages, or you can paste the competitor pages in. The third needs one that can run on a monthly schedule, or you can run it by hand each month.

1. Draft the situation analysis

I lead marketing at [company], which sells [what] to [whom] in [market]. I'm
writing our SOSTAC plan for [period] and need a first draft of the Situation
stage, "where are we now?".

Attached are:
- last year's marketing and sales results against our objectives
- our customer research or survey results
- [any other evidence, such as reviews or search data]

Our main competitors are [names and websites].

Write a situation analysis that ends in three to five findings. For each
finding give: the finding in one sentence | the evidence from the attached
files or competitor sites | what it means for next year's plan.

Then add a short section on each competitor: who they target, how they
position themselves and what has changed recently, from their own websites.

List anything you couldn't verify or open separately, rather than guessing.
This is a first draft for my team to challenge, so flag your weakest
finding.

2. Check a plan against the six stages

Below is our draft marketing plan. I want to check it follows SOSTAC:
Situation (where are we now), Objectives (where do we want to be), Strategy
(how do we get there), Tactics (the marketing mix that carries the strategy),
Action (who does what, when, with what budget) and Control (how we know we're
getting there).

[paste plan]

Give me a table with the columns: Line or section from the plan | The SOSTAC
stage it belongs in | Is it in the right place? | Problem, if any.

Then list:
- tactics written up as strategy
- objectives that describe activity rather than results
- objectives with no measure in Control
- tactics with no named owner or date in Action

Quote the plan's own words. Don't add objectives or tactics we haven't
written; where something is missing, say so.

3. Run the monthly control report

Run this on the first working day of each month.

Our marketing objectives for [period] are:
[list each objective with its target and date]

Attached are this month's exports: [name the reports, such as web analytics,
CRM and ad platform exports].

Give me a table with the columns: Objective | Target | Where we are now |
Change since last month | On track? (yes/at risk/no) | What drove the change,
if the data shows it.

Then list three questions the team should discuss at this month's review.
If an export is missing or a number can't be calculated from the files, mark
it "not in data" rather than estimating it.
Read the episode transcript

James: Most marketing plans I'm shown start with tactics. A list of channels, a content calendar, a few campaigns, and somewhere near the bottom a line about objectives. There's a planning model that fixes that by putting things in the right order, and it's the one I come back to more than any other. I'm James Vickers, this is Manual Focus, and in this Basics episode Hannah and I are taking apart SOSTAC.

Hannah: Hi James. I'll admit this is a slightly unusual one for me, because it's not an AI topic. But it turns out to be a very good frame for working out where AI belongs in a plan, so I'm glad we're doing it.

James: We'll get there. Start with the basics. What is it and where does it come from?

Hannah: SOSTAC is a planning model created by a British marketer called PR Smith in the nineteen-nineties. The letters stand for Situation, Objectives, Strategy, Tactics, Action and Control. And the reason it's lasted is that each stage answers one plain question. Where are we now? Where do we want to be? How do we get there? Then the detail of what we'll do, who does it, and finally, how do we know we're getting there?

James: And it's well used. Dave Chaffey, who writes a lot on digital marketing, notes it was rated among the most popular marketing models in a poll run by the Chartered Institute of Marketing.

Hannah: So take me through it the way a marketing team would actually use it. Situation first.

James: Situation analysis is the evidence for everything after it. Who your customers are and what they want, who your competitors are and how they position themselves, how you did against last year's objectives, and the strengths and weaknesses that matter for the next twelve months.

Hannah: That sounds like it could go on for ever.

James: It often does. The most common thing you'll see is a long deck of charts with no conclusions. Nobody can tell which facts matter, so the rest of the plan ignores them. The test of a good situation analysis is that it ends in three or four findings, each with its evidence. Something like, we're losing first-time buyers to a cheaper competitor, and here's the data that shows it.

Hannah: And that's where AI is already useful, I'd say. Pulling the data together, summarising competitor sites and reviews, synthesising research. That's the slog that used to make a proper situation analysis too expensive for a lot of teams.

James: It is. But deciding which findings matter stays with a person. Then objectives. Where do we want to be?

Hannah: PR Smith recommends SMART objectives here. Specific, measurable, achievable, relevant and time-bound.

James: And the discipline I'd add is tying them to business results. "Grow online revenue from new customers by fifteen per cent by next September" gives the plan a target. "Increase brand awareness" doesn't, because nobody can say whether you hit it. And keep the business objective separate from the marketing objectives that serve it. Revenue's the business objective. New customer numbers, conversion rate, repeat purchase, those are the marketing objectives that drive it.

Hannah: Then the stage people seem to argue about most, strategy and tactics. How do you tell them apart?

James: Strategy is the route. Who you'll target, how you'll position the brand against the alternatives, which channels carry the plan and which partners you'll work with. Tactics are the details of that route, what PR Smith describes as the marketing mix. The specific products, prices, places and promotions.

Hannah: I think that blur is where most plans go wrong, isn't it? A list of channels with "strategy" written at the top.

James: Very often. And the cost is real, because a list of tactics gives you no basis for saying no to anything. The test I use is whether the line would still be true if every campaign changed. "Win cyclists who train indoors through the winter, through coaches and clubs rather than paid social." That survives a change of campaign, so it's strategy. "Run a January indoor training challenge" is a tactic that serves it.

Hannah: That's a useful test. Our next Basics episode goes further into this, the difference between strategy, campaigns, creative and execution.

James: And the channel choices inside a strategy have their own Basics episodes too, owned, paid and earned media, and above the line versus below the line. Those are two different ways of sorting the same channels, and a strategy should be clear on both.

Hannah: Can I push on tactics for a second? You said the marketing mix. For anyone who hasn't come across it, that's the four Ps, isn't it?

James: Product, price, place and promotion. PR Smith's article mentions the extended seven Ps as well. The point for a plan is that tactics are wider than promotion. A price change or a new stockist can do more for an objective than another campaign.

Hannah: That's a point I don't think gets made enough. Most marketing teams I'd imagine only control the promotion part.

James: Which is exactly why the plan matters. If the situation analysis says the problem is price, a better advert won't fix it, and the plan is the document that lets marketing say so to the rest of the business.

James: It does. Then action, which is the bit most plans skip because it's dull.

Hannah: PR Smith frames it as making sure the tactics are actually carried out well. Resources, project management, training.

James: In practice it's an owner's name against every piece, a timeline, a budget, and the briefs and processes that get work out of the door. The plans that fail in delivery nearly always fail here. Everyone agreed what to do, and nobody was named as doing it.

Hannah: And then control. Are we getting there?

James: The measures for each objective, how often you report, and the points where the team sits down and decides what to change. A plan without control can't learn. So the same mistakes come round again next year.

Hannah: And the danger there is measuring what's easy rather than what the objective needs.

James: That's the big one. And the rhythm matters as much as the measures. In most teams I'd want a short monthly report against each objective and a proper quarterly review where you're allowed to change the tactics, while the strategy stays put unless the situation has genuinely changed.

Hannah: So control is where the plan gets updated, not just scored.

James: Exactly. Clicks are easy, by the way. Whether the new customers came back is harder. The attribution tear-down playbook in The Lens is useful here, because it tests whether the numbers on your dashboard reflect what actually drove the result.

Hannah: So, AI. PR Smith wrote about this himself, for the Chartered Institute of Marketing in September twenty twenty-five, alongside an AI edition of his SOSTAC guide. He named situation analysis, strategy, tactics and actions as the stages where AI is especially relevant. And his advice was to treat any AI-generated plan as a first draft only. He also argues that marketers should behave more like scientists, testing and adjusting all the time rather than writing a plan and waiting a year to find out.

James: Which I agree with. If you map it onto the three layers of AI we covered in the first Basics episode, chat helps with drafting and stress-testing, an agent can build the situation pack or the weekly control report, and the choices, the targets, the audience, the position, stay with people.

Hannah: I'd go a little further, actually. I think AI makes the model more useful, because the two evidence stages, situation and control, are exactly the ones teams skimp on when time is short.

James: That's our view too. AI takes out the hours that used to make a thorough situation analysis and a proper control loop too expensive for most teams. The quarterly planning ritual playbook shows how to run that loop every quarter rather than once a year.

Hannah: So, the jobs to hand over?

James: Get AI on this: the situation pack. That's the one that eats the most time.

Hannah: Give it last year's results, your customer research and a list of your main competitors' websites, and it hands back a draft situation analysis with three to five findings, each with the evidence under it, and a list of what it couldn't verify. A person still decides which findings matter.

James: Second, get AI on checking the plan you've already written.

Hannah: Paste in the draft plan and ask it to sort every line into the six SOSTAC stages. It hands back a table showing which stage each line belongs in, where tactics are sitting under strategy, and which objectives have no measure in control.

James: And third, the control report itself.

Hannah: Set it up as a monthly routine. Give it the objectives and the data exports, and each month it reports progress against each objective, what's moved, and the questions the team should discuss at the review. The prompts are in the show notes.

James: Let's finish with where people go wrong.

Hannah: From the article, three things. A situation analysis that's a data dump with no conclusions. Objectives that describe activity, like "post three times a week", instead of results. And tactics that don't trace back to any strategy.

James: I'd add one. Treating SOSTAC as a document you write once a year and file. It's meant to be a loop. And it scales down too. For a single campaign, give each stage two or three lines. The situation finding the campaign responds to, the one objective, the audience and position, the main activity, the owner and date, and the single number you'll judge it by. If any of those is blank, the campaign isn't ready to brief.

Hannah: That's a good test for any brief, really.

James: And on length, people ask how long a SOSTAC plan should be. As long as the decisions need and no longer. For an annual plan, the situation and control sections usually take most of the space, because that's where the evidence and the measures live. Strategy should fit on a page. If it doesn't, it usually isn't a strategy yet.

Hannah: I like that. The strategy section as the shortest part of the plan.

James: The shortest and the hardest to write.

James: So the takeaway. SOSTAC works because it makes you answer the questions in the right order, and AI now makes the two evidence stages cheap enough that there's no excuse to skip them.

Hannah: And the article has the full table of stages and common mistakes.
