    I will introduce the basic notions and properties of factorisation
    systems. A factorisation system on a category provides a way of
    splitting every map into a composite of two maps from specified
    sub-classes of morphisms. There are strong and weak varieties of such
    systems, depending on how canonical is the factorisation. I will
    discuss how in the former case a functorial factorisation and a monad
    on the arrow category are obtained. If there is time I will also
    outline the idea of factorisation systems generated by certain
    classes of morphisms.
