『The Personal MBA』要約

Josh Kaufman’s "The Personal MBA" argues that a business education can be self-assembled from first principles rather than purchased through a graduate degree. Kaufman, a former corporate manager, contends that an MBA overcharges for networking and credentialing while teaching concepts available in books, and he organizes his alternative curriculum around five interlocking areas: value creation, marketing, sales, value delivery, and finance. Within those, he presents named mental models such as the Iron Law of the Market (no market need dooms any offering), the Core Human Drives (the desires for acquisition, bonding, learning, defense, and feeling), and the Expectation Effect (customer satisfaction is the gap between expectations and perceived results). Kaufman also popularized the "four pricing methods" (replacement cost, market comparison, discounted cash flow, and value comparison) and the "twelve standard forms of value," including product, service, shared resource, subscription, resale, lease, agency, audience aggregation, loan, insurance, capital, and speculation. He explains the "five parts of every business" (value creation, marketing, sales, value delivery, finance) and warns against "analysis paralysis" and premature scaling. The book is deliberately practical: chapters are short, framed as standalone lessons, and draw on examples from real companies like Apple, Walmart, and Netflix rather than fictional case studies. Kaufman closes with sections on working with yourself and others, covering "locus of control," the "five-factor model" of personality, and the "strengths and weaknesses" trade-offs. First self-published in 2010 and later revised, the book is less a get-rich manual than a structured glossary of business reasoning, aimed at founders and employees who want an MBA’s conceptual vocabulary without the tuition or the two-year absence from the market.
