  Using ideas of Olson \cite{Ols} who showed that the system of effect
operators of a Hilbert space can be ordered by the so-called spectral order
such that the system of effect operators is a complete lattice. Using his
ideas, we introduce a partial order, called the Olson order, on the set of
bounded observables of a complete lattice effect algebra. We show that the set
of bounded observables is a Dedekind complete lattice.0
