Agile is viewed as a strategy to hasten the development of new products since it is flexible, practical, and cost-effective. The startup firm where the case study was conducted is a poultry retail agrotechnology startup. However, there are several difficulties in practice. One of the company's main products is IoT-based poultry technology solutions and livestock management software. The product development has been using Scrum since January 2022. However, there are still issues with the implementation, such as projects not being finished on schedule, workload being distributed unevenly, and incorrect documentation and reporting on team and company performance. Expectations for project completion might be as high as 80%. However, only 50% of projects are completed. The work process is still ineffective, especially when gathering requirements and reviewing products. The purpose of this research is to identify the critical failure factors that contribute to the failure of Scrum implementation in the company and provide a recommendation to be a strategy to improve Scrum implementation in the company to solve the issues. The TOPSIS approach was employed in the research. The lack of a complete set of agile practices, lack of project management capabilities, lack of agile progress tracking, the organization is too political, and lack of management commitment were the most relevant factors to the implementation failure. Resistance from groups or individuals, lack of customer relationships, and ill-defined customer roles are the ones that have the most negligible impact. Recommendations have been arranged for the company for a strategy to improve the implementation of Scrum. © 2022 Little Lion Scientific.
