The industry usually frames these as opposing forces requiring balance. The
framing is misleading. Heritage that is not reinterpreted does not survive as
heritage; it becomes a costume. Innovation that is not anchored in an
established identity does not accrue to the house; it produces a novel object
that any competitor could have produced.
The genuine question is narrower and more useful: which elements of a house are
load-bearing, and which are period detail. Load-bearing elements are those whose
removal would make the house unrecognisable to the people who value it most.
Period detail is everything that has become familiar through repetition without
being essential.
Organisations are consistently poor at telling these apart, and the error runs
in a predictable direction: familiarity is mistaken for necessity. Habits
acquire the status of principles simply by lasting. A house can end up defending
a distribution arrangement, a category or a communication convention in the
sincere belief that it is defending its identity.
The reverse error is less common but more damaging when it occurs. A house that
treats everything as negotiable in pursuit of relevance discovers that it has
spent the very asset that made relevance commercially valuable. Its output may
be well received and still fail to accumulate, because nothing about it is
specific to that house.
What separates the two judgements is not method but understanding: a specific,
internally shared account of what this house is that is precise enough to
generate a clear answer when a difficult case arises. Houses that possess such
an account can change a great deal without losing themselves. Houses that do not
tend to alternate between paralysis and drift.
