Why Nokia
The most rigorously documented case of signal suppression in the management literature
Most organizational failures are documented after the fact, in journalism and litigation. Nokia's signal suppression failure is documented in a peer-reviewed academic study based on direct interviews with Nokia executives and engineers conducted while the company was still operating. Vuori and Huy (2016) described specifically how fear of negative consequences created a systematic pattern of upward filtering that prevented accurate competitive intelligence from reaching decision authority.
Nokia is not an anecdote. It is a documented organizational mechanism. The mechanism is Signal Line Protection's primary diagnostic target.
