Very Small Entities (VSEs), crucial to the software industry, often struggle to balance agile practices with the need for standardized processes to ensure quality. This research addresses the challenge of adopting ISO/IEC 29110 in agile VSEs, where resource constraints and a preference for informality hinder standardization. We propose a multi-faceted intervention strategy focusing on gradual, low-intrusion adoption of ISO/IEC 29110, leveraging existing tools, and aligning with agile principles. The methodology involved mapping, case studies, and professional surveys to develop and validate this strategy. The expected outcome is an implementation strategy, supported by tools and instruments, to enhance both process and product quality in VSEs.
