  The complexity of a business environment often causes organizations to
produce several inconsistent views on the same business process, leading to
fragmentation and inefficiencies. Business process view integration attempts to
produce an integrated view from different views of the same model, facilitating
the management of models. To study trends around business process view
integration, we conduct a systematic literature review to summarize findings
since the 1970s, up to its potential novel applications. With a starting corpus
of 798 documents, this survey draws up a systematic inventory of solutions used
in academia and in the industry. By narrowing it down to 51 articles, we
discuss in-depth 15 business process integration techniques papers. After that,
we classify existing solutions according to their practicality. Our study shows
that most integrated views are constructed by annotation, using formal merging
rules. Finally, we explore possible future research directions. We highlight
the application of view integration to the blockchain research area, where
stakeholders can have different views on the same blockchain. We expect that
this study contributes to interdisciplinary research across view integration.
