The aim is not to evaluate the brand overall, but to understand individual, completed transactions: what actually influenced the choice, who took part in the decision, which criteria were decisive, and at what point in the buying journey the client rejected or accepted the offer.<\/p>\n<p>This method answers a question that sales data cannot resolve. CRM records the outcome and the reason assigned by the salesperson, but it does not capture the other party&#8217;s perspective. Meanwhile, <strong>B2B purchasing decisions<\/strong> are often made by buying committees, involve multiple stakeholders with different priorities, and unfold over time. Salespeople usually see only part of this process &#8211; most often the part in which they discuss price. Everything else may remain outside their field of view.<\/p>\n<p>Win-loss research is particularly valuable when the value of an individual transaction is high, the sales cycle is long, and competition for the client is intense. It is worth using when:<\/p>\n<ul>\n<li>the win rate is declining and the sales team cannot identify a consistent reason;<\/li>\n<li>the company is launching a new product or entering a new segment and wants to understand how it is perceived by the market;<\/li>\n<li>there is a discrepancy between what marketing promises and how clients describe the offering;<\/li>\n<li>the organization wants to verify whether its positioning reflects the actual criteria used to select a supplier.<\/li>\n<\/ul>\n<p>Win-loss analysis does not replace satisfaction research or market segmentation. It answers a narrower but highly specific business question: why was this particular transaction won or lost, and what does this mean for the repeatability of the sales process?<\/p>\n<h2>How do you conduct research into the reasons behind lost bids step by step?<\/h2>\n<p>Reliable <strong>win-loss analysis<\/strong> relies primarily on in-depth interviews with people who actually participated in the purchasing decision on the client side. A closed-ended survey can be a supplement, but on its own it does not capture the nuances of the decision-making process. The research process in projects conducted by Hume&#8217;s Institute usually consists of several stages.<\/p>\n<p><strong>1. Sampling transactions.<\/strong> The starting point is a list of closed sales opportunities &#8211; both won and lost. Maintaining balance is crucial: analyzing only losses distorts the picture because it does not show what works. The sample should include different segments, contract sizes, and stages at which the decision was made.<\/p>\n<p><strong>2. Reaching the right interviewee.<\/strong> In <strong>B2B purchasing decisions<\/strong>, one person rarely makes the decision alone. An interview with the end user will provide a different picture than a conversation with the finance director or procurement department. Valuable research identifies the role each person played on the buying committee and reaches those who genuinely influenced the outcome.<\/p>\n<p><strong>3. Interview guide.<\/strong> The conversation reconstructs the decision-making journey chronologically: from the moment the need was defined, through the creation of a supplier shortlist and evaluation criteria, to the final decision. Questions are open-ended and neutral so that they do not suggest answers. Rather than asking, &#8220;was the price too high,&#8221; the research explores which factors determined the choice and in what order.<\/p>\n<p><strong>4. Analysis and coding.<\/strong> The collected statements are categorized according to recurring themes &#8211; technical criteria, relationship quality, supplier credibility, commercial terms, and experience with the bidding process. Only at this stage do patterns become visible that a single transaction would not reveal.<\/p>\n<p>This is where one of the method&#8217;s most important findings emerges. As Hume&#8217;s Institute experts point out, salespeople often explain a loss by referring to price because it is the most convenient and least personally burdensome explanation. Yet, when asked neutrally, the client may indicate entirely different reasons: a lack of understanding of their needs, a delayed response to an inquiry, an unclear proposal, or greater trust in a competitor. Price can be a rationalization for a decision that was made for other reasons.<\/p>\n<p>This distinction has direct practical implications. If an organization believes it is losing on price, it reduces margins. If the real reason was response time or the quality of proposal communication, a price reduction fixes nothing &#8211; it only changes the profitability of won contracts. Research into <strong>reasons for supplier selection<\/strong> makes it possible to distinguish genuine causes from convenient ones.<\/p>\n<p>Win-loss interviews also provide information about competitors as seen through the client&#8217;s eyes &#8211; how they were positioned, which arguments carried the most weight, and at what point the client shifted in their favor. This perspective is unavailable from internal sales data.<\/p>\n<h2>What mistakes most often undermine the credibility of win-loss analysis?<\/h2>\n<p>The method is effective only when research rigor is maintained. In practice, <strong>research into the reasons behind lost bids<\/strong> is often weakened by several recurring mistakes that are worth understanding before launching a project.<\/p>\n<p><strong>Interviews conducted by the salesperson who handled the transaction.<\/strong> This is one of the most common and serious pitfalls. A client may not tell the person who lost their contract that the proposal was unclear or that trust was lacking. They may give an evasive answer &#8211; often citing price. Interviewer neutrality is a prerequisite for obtaining honest responses, which is why <strong>win-loss analysis for B2B<\/strong> gains credibility when conducted by an independent external party.<\/p>\n<p><strong>Researching losses only.<\/strong> An analysis of lost opportunities alone shows what failed, but not what should be retained. Without won transactions, there is no point of reference, and it is easy to overreact by &#8220;fixing&#8221; things that actually work in the company&#8217;s favor.<\/p>\n<p><strong>Reaching the interviewee too late.<\/strong> Memories of the details of the decision-making process fade quickly. After several months, the client remembers the outcome but not the sequence of events and arguments that led to it. Delays reduce data quality.<\/p>\n<p><strong>Leading questions.<\/strong> An interview guide built around the researcher&#8217;s assumptions leads to those assumptions being confirmed. If the questions suggest that the issue is price, the client may readily agree because it is the simplest answer. The neutrality of the interview guide is as important as the neutrality of the interviewer.<\/p>\n<p>It is also worth understanding how win-loss analysis differs from related approaches. Satisfaction research measures the overall attitudes of existing clients, but it does not reconstruct an individual purchasing decision and does not include those who chose a competitor. CRM data analysis shows the outcome and the internal interpretation, but not the client&#8217;s perspective. Win-loss analysis complements both sources by introducing the voice of the other party in the transaction. In Hume&#8217;s Institute projects, combining quantitative CRM data with qualitative interview material provides a picture that is less susceptible to the team&#8217;s internal biases.<\/p>\n<p>A limitation of the method is that it is time-consuming and dependent on the availability of interviewees. Not every client &#8211; especially one that rejected the proposal &#8211; will agree to an interview. Therefore, sample selection and the way contact is established affect the extent to which findings can be applied to the entire sales process rather than only to part of it.<\/p>\n<h2>What should a win-loss research project include?<\/h2>\n<p>For win-loss analysis to produce useful findings, the research project should be planned before the first interview. The following elements are the minimum required for reliable preparation:<\/p>\n<ul>\n<li><strong>A balanced sample<\/strong> covering won and lost transactions in justified proportions and across key segments.<\/li>\n<li><strong>A stakeholder map<\/strong> on the client side &#8211; determining who participated in the decision and who should be approached.<\/li>\n<li><strong>A neutral interview guide<\/strong> with open-ended questions that reconstruct the decision-making journey chronologically.<\/li>\n<li><strong>Conducting the research through an independent party<\/strong> or a person outside the team handling the given transaction.<\/li>\n<li><strong>A consistent coding framework<\/strong> for statements, enabling comparisons across transactions and the identification of patterns.<\/li>\n<li><strong>Comparing findings with CRM data<\/strong> to contrast the reasons reported by salespeople with clients&#8217; perspectives.<\/li>\n<\/ul>\n<p>Research designed in this way turns scattered sales anecdotes into structured knowledge of which <strong>reasons for supplier selection<\/strong> actually determine the outcome &#8211; and makes it possible to distinguish causes the organization can influence from those beyond its control.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>What does win-loss analysis involve?<\/h3>\n<p>Win-loss analysis is a study that reconstructs the actual reasons behind won and lost sales opportunities by going directly to decision-makers on the client side. It is based mainly on in-depth interviews in which the interviewee reconstructs their decision-making process &#8211; from defining the need to selecting a supplier. The result is a structured picture of the criteria that actually influenced the outcome of the transaction.<\/p>\n<h3>Why does a salesperson assess the reason for a loss differently from the client?<\/h3>\n<p>A salesperson sees only part of the purchasing process, most often the part in which commercial terms are discussed, and may therefore explain a loss by referring to price &#8211; an explanation that is convenient and least personally burdensome. When asked neutrally by a third party, the client may identify other factors, such as a lack of understanding of their needs, response time, or trust in a competitor. Price can be a rationalization for a decision that was made for entirely different reasons.<\/p>\n<h3>When should win-loss interviews be conducted after a purchasing decision?<\/h3>\n<p>Ideally, as soon as possible after the decision, usually within a few weeks, while the client still remembers the sequence of events and arguments. Waiting too long means the interviewee remembers the outcome but not the details of the decision-making process. Contacting them too early, in turn, may be perceived as intrusive, so the timing should be adapted to the nature of the relationship with the particular client.<\/p>\n<h2>Ask about research into won and lost opportunities in your B2B business<\/h2>\n<p>If you want to base sales decisions on what clients say rather than on your team&#8217;s assumptions, Hume&#8217;s Institute will design and conduct win-loss analysis tailored to your sales process. <a href=\"https:\/\/humes.pl\/en\/contact\/\">Contact us<\/a> to discuss the scope of research into the reasons behind won and lost opportunities in your organization.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Your sales team has lost another tender, and the CRM report once again says: &#8220;too expensive.&#8221; The problem is that this is the salesperson&#8217;s version, not the client&#8217;s &#8211; and the difference between the two determines whether you improve your sales process based on facts or assumptions.
