PSD.17:2 - Problem
A practice can preserve its visible forms while losing the reasons that made them useful. A concern map becomes a diagram to complete. A conditional comparison becomes an unconditional recommendation. A workshop’s apparent agreement becomes a claim that affected people were represented. These changes can travel through teaching, templates, peer imitation, commissioning and recognition even when nobody intends them.
The reverse failure is to resist every variation in the name of fidelity. A receiving team faces different access, values, uncertainty or authority conditions, but is told to reproduce the original format. It may preserve the carrier while making the Method unusable.
Neither a new edition nor one successful engagement settles this problem. The practitioner needs to distinguish what was made available, what reached another person, what was actually done, what was selected and retained, and what consequence followed. A bounded intervention can then be chosen without pretending to control an entire discipline.
