An elementary class of evolutions in unital Banach algebras is obtained by integrating product functions over Guichardet's symmetric measure space on the half-line. These evolutions, along with a useful subclass, are characterised and a Lie{Trotter product formula is proved. The class is rich enough to form the basis for a recent approach to quantum stochastic evolutions.
