Evaluation and Recommendation for Scrum Implementation Improvement with Hybrid Scrum Maturity Model: A Case Study of A New Telco Product

In 2019, a telco company launched a new product for the youth. It has the tagline 'Everything You Want' that gave young customers the freedom to bundle their mobile communication packages. The Blue team developed the product guided by Scrum, However, there were troubles during software development, such as missing the targeted deliverables. A measurement of the Scrum process maturity level was conducted to address the problems. It followed the modified Scrum Maturity Model, which was updated from the 2017 Scrum Guide and Scrum Body of Knowledge version 3. The assessment showed that the Blue team achieved maturity level 1 (Initial). It was attained with 16 'Fully Achieved' practices, 49 'Largely Achieved' practices, and 14 'Partially Achieved' practices. Once the maturity level and existing problems were identified, recommendations based on Scrum components (Scrum roles, Scrum artifacts, and Scrum events) were proposed. It aimed to improve Scrum practices that had not been fully achieved by the Blue team.
