This IDC Survey Spotlight analyzes retailers' sources of innovation funds in the context of a broader business model innovation process. It explains why retailers must involve internal stakeholders and the ecosystem of partners in the process of sourcing funds, and why they should frame it within unified innovation strategies. It leverages data from IDC's 2020 Global Retail Innovation Survey, in which we posed 11 maturity questions to understand retailers' approach to innovation. We asked retailers to self-assess on topics such as innovation strategies, co-innovation activities, retail commerce platform implementation, the use of artificial intelligence/machine learning (AI/ML) capabilities, innovation funds sourcing, innovation piloting, and innovation implementation and scaling. The survey includes 25 questions.
