Version Française ICI: http://bit.ly/TOD-FR English translation of my lateral thinking essay on Organizational Performance. Feel free to share, print, disseminate and teach with credits: "CC-BY-NC-SA Paul Merino, The Time Hunter @SEUILS". This is a mental model for a "DNA of Effectiveness". This model accounts for the 4 DNA nucleotides, and also for the 2 alternating residues forming the DNA backbone - totaling 6 generic elements which I call "Doorways". What's interesting is that the 4 Doorways here associated with DNA nucleotides represent "Value", whilst the 2 others (here associated with DNA backbone) represent "Work". I titled this 1997 essay after its central tool "The Merino's Eye" because this is how I formed my understanding of the dynamics of Time, but it is more neutrally subtitled "The Theory Of Doorways" (TOD).
