An MBA is an academic qualification, taught mostly by academics. Academics generally won&#x27;t teach Lean because there hasn&#x27;t been much academic discussion of it (yet). Mind you, I completed mine in 2013, so it&#x27;s possible there&#x27;s been some changes since.<p>Entrepreneurial units in my MBA focussed on writing 40-page business plans for conventional bricks-and-mortar businesses with known business models. Which is fine, because that&#x27;s what 90% of entrepreneurs do. Building a business without knowing the business model before you start is stupid risky according to this mindset (and they&#x27;re right, it is, but that&#x27;s half the fun).
