   Corrected six overstated or inaccurate claims: clarified that 'the customer is always right' is a retail-era maxim, not an Agile principle (Agile emphasizes customer collaboration); reframed the Gaussian copula as one important contributor to mispriced CDO risk rather than the single universal cause of the 2008 crisis; qualified the Lehman VaR framing to note VaR by design says little about extreme tail events, rather than implying its outputs were predictably wrong; corrected the Waterfall description to sequential plan-driven engineering/manufacturing practice that can work when conditions hold rather than consistently failing; flagged the British-India cobra bounty as a widely repeated but poorly documented parable; and reframed Nokia's market-segmentation framework as one factor among several (software, ecosystem, organizational) in its smartphone struggles. The Porter/Five Forces Android illustration was left as a valid example.

   Before

   The article said Lehman VaR models made the collapse predictably wrong, Waterfall came from civil engineering and consistently fails, 'the customer is always right' is an Agile principle, the Gaussian copula was the universal standard cause of the CDO crisis, and Nokia's internal framework caused its smartphone failure.

   After

   Qualified the VaR, Waterfall, copula, and Nokia claims to acknowledge multiple causes and design limitations, corrected the false Agile attribution, and flagged the cobra story as a parable.

   Why: The claims were more absolute or mono-causal than the evidence supports, and the Agile attribution was incorrect. Corrections scope the claims and fix the attribution rather than adding new sources.
