  The $R$-parity-violating Minimal Supersymmetric Standard Model (RPV-MSSM) can
naturally accommodate massive neutrinos as required by the oscillation data.
However, studying the phenomenology is complicated due to the large number of
undetermined parameters involved. Thus, studies are usually restricted to
specific submodels. In this work, we develop an approach that allows us to be
less restrictive. Working in (almost) the completely general RPV-MSSM setting,
we analyze the structure of the neutrino mass matrix, and identify -- for the
case of two massive neutrinos -- only four minimal classes of structures that
can solve the neutrino data; we call these Minimal Oscillation Models (MOMs).
We study the general features of each MOM class, and present numerical fits to
the oscillation data. Our approach allows us to study all RPV models satisfying
the neutrino data in a unified manner, as long as they satisfy the MOM
criteria. Through several examples, we show that this indeed holds for many
interesting scenarios.
