Bottom-up and top-down research both have a role
Anyone who has wrestled with the question of ‘which is best?’ might be reminded of the comedian Harry Hill and his tongue-in-cheek debates. In market research, such as in the environmental technology and services sector, we often find ourselves having the same internal argument between top-down and bottom-up approaches to research. Faced with a new client brief, we weigh up our options: What will deliver the most insight? What fits the budget? What is actually realistic within the timeframe?
Market quantification is one of the clearest examples of this tension. On the one hand, the classic bottom-up approach remains the gold standard. It’s rigorous, detailed and grounded in primary research be they interviews with market participants to careful mapping of supply chains and competitive dynamics. But this thoroughness comes at a price, namely long timelines, high research effort and higher costs. For many clients, these demands simply aren’t viable.
On the other hand, there is the top-down route. It leans on what is already in the public domain – market reports, financials, government statistics etc. and applies structured analysis to derive market size, trends, and opportunities. It is faster and more cost-effective. Yet it has its own pitfalls. Generic data may not neatly align with the client’s actual market; sources may be outdated while there may be uncertainty as how research was conducted in the first place.
So, the question remains: which approach is best?
Offering choice at the proposal stage is essential …
A recent global study I was involved with illustrates the benefits of keeping both approaches in mind. A multinational client wanted to identify which regions, and which specific markets within those regions, offered the best growth opportunities for its product portfolio.
From the outset, it was clear that proposing a full bottom-up study across every region would have been unrealistic. Not only would the project have become long and costly, but it would almost certainly have pushed the proposal out of consideration entirely. Instead, a top-down approach was recommended for the first phase. Fortunately, the product scope was well-defined, making it possible to structure the secondary research in a focused way.
But relying solely on existing data never gives the full picture. To ensure that the analysis reflected real-world conditions, and to address nuances in the client’s brief, targeted primary research was also offered. Ten interviews with major suppliers and distributors added colour, confirmed assumptions and fine-tuned findings drawn from secondary sources. It was a light-touch bottom-up layer that strengthened the credibility of the top-down focus.
… especially as projects develop and more detailed information is sought
Once the global overview was complete, attention shifted to markets with the greatest potential. This next phase required a completely different approach. Segmentation, competitive structures, and market channels demanded detail that secondary sources simply couldn’t provide. Here, a bottom-up approach anchored in interviews, market mapping and competitor analysis was essential.
This shift illustrates an important fact, namely that research approaches should be based on the ultimate aims of a project. While top-down research can set the direction of a study, often only a bottom-up stage will be able to deliver the level of granularity needed for concrete decision making.
Questions worth asking before you propose an approach
My experience of this recent global project reinforces several questions that we should all consider when shaping a proposal:
- Why is the research being commissioned? Is the client looking for a market overview, or is the research tied to a major investment such as an acquisition? When clients are preparing to make significant investments, bottom-up research is often non-negotiable.
- How big is the research scope? Bottom-up research is far easier to justify for single-country or regional studies. As the geographic scope expands, so does the time and cost which often pushes the case towards either a top-down or blended method.
- How flexible is the client? Some clients arrive with a fixed view of how research should be carried out whereas others welcome guidance. Early conversations can offer strong clues. In many cases, proposing an approach different from what the client initially suggests shouldn’t be viewed as risky – it will be valued.
- Should limitations in a client brief be openly discussed? Absolutely. Clients are not always aware of what is feasible. Some desired outcomes may be difficult, or unrealistic, to deliver within a given budget. At other times, only a bottom-up approach will meet the needs of a client entering a new market or considering a major investment. Raising these points early prevents later problems.
Flexibility towards research methods offers the best of both worlds for clients
Ultimately, there is no universal answer to whether a top-down or bottom-up approach for research is ‘best’. Each brings strengths while each has limitations. Yet, most importantly, both have a place when assembling a proposal. Successful research projects often come from a blend of both – using top-down for direction and bottom-up for depth.
Communicating how these approaches can shape outcomes for a client should be a vital part of any proposal. While top-down certainly has cost and time advantages pursuing a bottom-up approach can give detail that no review of secondary data can match. Blended approaches, combining both of these elements, shouldn’t be overlooked especially because they can deliver value at different stages of a project.
