\section{Introduction}  Although computational creativity is well studied in both theory and  practice, the role of \emph{serendipity} hasoften not  been discussed largely neglected  in this field -- even though serendipity has played a well-documented  role in historical instances of scientific and technical creativity.  One reason for this omission may be that the field of computational  creativity has tended to focus on artistic creativity. But creativity, which is modelled in such a way that creative outputs are largely under the direct control of the creative agent. However,  serendipity is increasingly seen as relevant within the arts  \cite{mckay-serendipity} and other creative enterprises  \cite{kakko2009homo,engineering-serendipity}: \cite{kakko2009homo,engineering-serendipity}, where  it is managed and encouraged with methods drawn from fields ranging from architecture to data science.  %  An interdisciplinary perspective on the phenomenon of serendipity  promises further illumination. Here, we consider the potential for  formalising this concept concept. This paper follows  and investigate its utility expands \citeA{pease2013discussion}, which is a robust brief survey where many of the ideas developed here were first presented. The current paper uses the opportunity of a fresh start and a wider canvas to advance some bold claims about the usefulness of serendipity  as a new framework for computational creativity. Serendipity centres itself is centred  on reassessment. For example, a non-sticky ``superglue'' that no one was quite sure how to use turned out to be  just the right ingredient for 3M's Post-it\texttrademark\ notes.  %
