Most companies operate under a dangerous illusion. In boardrooms, executives nod confidently when discussing the “target customer.” They have buyer personas with fictional names and stock photos pinned to the wall. They believe they know who buys from them. But Philip Kotler, in his diagnosis of the second deadly sin of marketing, throws a bucket of cold water on this belief: If your last market study is more than three years old, you don’t know your customer. You know a ghost.
The market is a living organism that constantly mutates. What consumers thought, felt, and valued three years ago—when the economy, technology, and their personal priorities were different—no longer exists. Operating with outdated data is like trying to navigate today’s ocean with a map from the last century. You will crash.
The Symptoms of Commercial Blindness
How do you know if your company suffers from this myopia? Kotler highlights three unmistakable red flags.
Sales below expectations. If your product is good but it doesn’t sell, it’s not the market’s fault; it’s your disconnection from it. The price may be wrong, or the message simply doesn’t resonate anymore.
Massive returns and complaints. A return isn’t just a lost sale; it’s a broken promise. It means the customer expected one thing and received another. If this happens frequently, your communication is failing to explain who you really are.
“Archaeological” research. If, when asked about market research, someone hands you a dusty report from five years ago, you have a serious problem.
Beyond the Survey: The Ethnography of Consumption
To cure this blindness, it’s not enough to send a satisfaction survey by email. Kotler urges us to go deeper, using a mix of classic and modern methods to hear the true “voice of the customer.”
Focus groups are useful for exploring initial reactions. Mercedes used them when evaluating the Smart car in the U.S. By hearing American consumers say “it looks unsafe,” they avoided a disastrous launch.
In-context research, at home and in the store, reveals truths people either hide or don’t consciously understand. Paco Underhill, pioneer of retail anthropology, discovered powerful insights simply by observing behavior: men hate asking for help and move quickly; if they don’t immediately see what they want, they leave. He also identified the importance of the “transition zone” at a store entrance, where customers are still slowing down and pay little attention to products.
Mystery shopping is another powerful tool. Kotler himself acted as a mystery customer at Pizza Inn and experienced painfully slow service—something internal reports never revealed.
Mining the Truth: CRM and Big Data
In the modern era, intuition must be complemented by hard analytics. Kotler emphasizes the power of CRM systems and data mining. Past purchases are the best predictor of future behavior. If a customer consistently buys newly launched technology, don’t send them clearance offers for outdated products. Offer them exclusive early access to the latest release.
Data analysis isn’t just about selling more; it’s about segmenting with surgical precision. Tools like perceptual maps allow you to see how consumers truly perceive you versus competitors—are you “reliable premium” or “cheap and risky”?
The Continuous Dialogue
The core message of this sin is simple: customer knowledge is not a one-time project; it’s a habit. Successful companies don’t run a study every five years—they maintain an ongoing dialogue. They build customer panels, monitor social conversations, and, above all, treat complaints not as annoyances but as free market intelligence.
To keep this information flowing and turn insight into action, you need an agile operational structure. GGyess WorkSuite allows you to centralize not only project management but also the critical information flowing between sales, support, and marketing teams—ensuring that customer insights don’t get lost in bureaucracy, but are quickly transformed into product improvements and effective go-to-market strategies, keeping your company aligned with real market conditions in real time.
