Crowdsourcing can be an efficient organisational strategy to harness innovation and agility by distributing work to Internet users. As crowdsourcing is different from other business strategies, organisations are often unsure about how to structure different crowdsourcing activities. Managing this problem, this book conceptualises and develops crowdsourcing as an organisational business process. To open the book, this chapter gives an introduction to business process crowdsourcing, as a necessary development to move crowdsourcing from an unstructured, immature form towards a more structured repeatable process. The chapter then sets the scene by defining the research objectives, presenting the research approach, and pointing out the contributions.
