Johnson, DTizard, DDamian, DBlincoe, KClear, A2020-11-202020-11-202020-11-022020-11-02https://hdl.handle.net/10292/13807CrowdRE has been argued to comprise four main activities: motivating crowd members; eliciting feedback; analysing feedback and monitoring context and usage data. However, determining requirements within a software ecosystem poses demands beyond those found by a single product owner. In this paper, we describe open challenges for CrowdRE in handling the many, competing and heterogeneous sources of RE data in a software ecosystem. We illustrate the case of Xero ecosystem - a global accounting software company - as an ecosystem platform provider and Figured - a developer of a farming industry application and one of Xero's partner apps.Copyright © 2020 IEEE.
