The Role of Market Analysis
Market analysis is the process of studying a market before we make a decision about it, whether that decision is launching a new product, entering a new country, raising a price, or just deciding where to put next year’s marketing budget. It sounds broad because it is broad. Market analysis isn’t one single technique, it’s really a collection of questions we work through, using whatever data and research we can get our hands on, before committing money to a decision that’s hard to reverse.
We’re going to walk through the main pieces: how big the market actually is, who’s already competing in it, who the customer is, and how the market is likely to change. Then we’ll get into how marketers actually use this to make a decision, because understanding a market and deciding what to do about it are two different skills.
How Big Is the Market, Actually?
The first question in almost any market analysis is size. If we’re thinking about launching a product, how many potential customers are actually out there, and how much money could we realistically capture from them?
A useful way to break this down is with three layers, usually shortened to TAM, SAM, and SOM.
- TAM is the total addressable market, the full size of the market if we somehow captured every possible customer.
- SAM is the serviceable addressable market, the portion of that we could realistically reach given our product, geography, and distribution.
- SOM is the serviceable obtainable market, the share we could realistically win given our actual resources and the competition we’re up against.
Let’s put numbers to it. Say a company is considering launching a plant-based protein bar in the United States. The total market for protein bars in the US might be worth around $3 billion a year, that’s the TAM. But this new company only plans to sell through health food stores and online, not mass grocery, so its SAM (the segment it can actually reach through those channels) might be closer to $600 million. And given that it’s a new entrant going up against established brands with much bigger marketing budgets and shelf space, a realistic SOM in year one, its actual obtainable market share, might be something like 2 percent of that SAM, or about $12 million in first-year sales potential.
That $12 million figure is a lot more useful for planning than the $3 billion headline number, and this is really the point of doing a TAM, SAM, SOM breakdown at all. A huge market size sounds exciting in a pitch deck, but it tells us almost nothing about what a specific company, with specific resources, can actually achieve. Investors and executives who’ve seen enough business plans know to ask for the SAM and SOM numbers specifically, because the TAM number on its own is close to meaningless for judging whether a plan is realistic.
Who Are We Actually Competing Against?
Market size doesn’t mean much without understanding who else is already fighting for it. This is where competitive analysis comes in, and it’s worth being broader than just listing the two or three obvious rivals.
Direct competitors are the obvious ones, other protein bar brands, in our example. But we also need to think about indirect competitors, other snacks entirely that are competing for the same occasion, like a piece of fruit, a granola bar, or a smoothie. And we need to think about how easy it is for new competitors to enter, and how much power our suppliers and retail buyers have over us.
This broader way of thinking about competitive pressure, covering rivals, new entrants, substitute products, and the bargaining power of both suppliers and buyers, comes from Michael Porter’s five forces framework, which has been a standard tool in market analysis since the late 1970s.
Why does this matter practically? Because a market can look attractive on size alone and still be a bad market to enter. If margins across the category are already thin because retailers have enormous bargaining power (as is often the case with grocery chains, which can demand slotting fees and aggressive discounts just to get a product on the shelf), that $12 million SOM figure from before might come with a much lower profit margin than the headline market size would suggest.
Who Is the Customer, and What Do They Actually Need?
Alongside size and competition, we need to understand who’s actually buying, and this is where market analysis starts to overlap with market segmentation. Not every customer in a $3 billion protein bar market wants the same thing. Some are buying for weight loss, some for muscle building after workouts, some just want a convenient breakfast substitute. Each of those segments responds to different messaging, different price points, and often different retail channels.
This is usually where qualitative research (talking to customers directly to understand their motivations) and quantitative research (surveying a larger sample to size those segments and confirm which ones matter most) both come into play. Market analysis without direct customer input tends to rely too heavily on assumptions about who wants the product and why, and those assumptions are wrong more often than marketers like to admit.
How Is the Market Changing?
A market analysis that only looks at today’s numbers misses something important, because we’re not launching into today’s market, we’re launching into whatever the market looks like by the time our product actually reaches customers, and then for years after that.
So we look at trends: is the category growing or shrinking, and how fast? Are consumer preferences shifting in a way that helps or hurts us? Plant-based eating, to continue our example, has been a genuine growth trend in North America and Europe over the past decade, which is exactly why a plant-based protein bar looks more attractive as a launch idea now than it would have fifteen years ago.
But trends can also reverse or plateau, and a market analysis that just extrapolates last year’s growth rate in a straight line for the next five years is asking for trouble. We also want to think about regulatory changes, input costs (protein ingredients, packaging, distribution), and whether larger competitors are likely to react once we actually launch and start taking share.
What Do Marketers Actually Do With All This?
Having the analysis is one thing. Using it to make a decision is another, and this is really where the value of market analysis shows up.
Take our protein bar example again. If the SOM analysis suggests $12 million in year-one sales potential, the next question is whether that’s enough to justify the investment. What does it cost to develop the product, secure retail distribution, and run a launch marketing campaign? If that cost is $8 million, a $12 million sales opportunity with reasonable margins might make sense. If the cost is $15 million, the market analysis just told us not to proceed, at least not in that channel, at that scale, in year one.
Market analysis also shapes positioning. If the competitive analysis shows the market is crowded with high-protein, high-price bars aimed at gym-goers, but relatively thin on convenient, lower-sugar options aimed at people replacing a mid-afternoon candy bar, that gap is a positioning opportunity the analysis has surfaced, not just a size number.
And it shapes risk management. If the trend analysis flags that a much bigger competitor, one with far more marketing budget and existing retail relationships, is likely to respond quickly to any successful new entrant, we might decide to move faster, price more aggressively to build share early, or pick a narrower launch channel where we’re less likely to draw that competitor’s attention right away.
What Are the Common Mistakes?
The most common mistake is stopping at the TAM number and skipping the SAM and SOM work, because the big number is more exciting to put in front of investors or an executive team. It’s also common to underestimate how competitors will react once a new entrant starts winning share, since a market analysis done before launch naturally reflects a market that hasn’t seen the new product yet, and that market will not stay still.
Another common mistake is relying entirely on desk research, industry reports, and existing data, without talking to any actual customers. Numbers from a market report can tell us a category is growing, but they can’t tell us why a specific customer would choose our specific product over what they already buy. That gap is exactly why qualitative customer research, alongside the numbers, tends to be part of a properly done market analysis rather than an optional extra.
Key Points to Take Away
- Market analysis combines market size, competitive analysis, customer understanding, and trend analysis into a picture that supports a real business decision.
- Break market size into TAM, SAM, and SOM rather than quoting the total market number alone, since the obtainable share is what actually matters for planning.
- Competitive analysis should go beyond the obvious direct rivals to include substitute products, potential new entrants, and the bargaining power of suppliers and retail buyers.
- Understand who the customer segments actually are and what they need, using both qualitative and quantitative research rather than assumptions.
- Trends matter because we are launching into a future market, not today’s market, so extrapolating current growth in a straight line is risky.
- The point of market analysis is to support a specific decision, whether to launch, how to price, how to position, or how much risk to take on, not just to describe the market for its own sake.
