Comparison of Scrum Maturity Between Internal and External Software Development: A Case Study at One of the State-Owned Banks in Indonesia

Abstract

Bank XYZ, a state-owned bank in Indonesia, has just begun its digital transformation and employed scrum methodology for only one year. Lack of resources in the internal IT division (Div-IT) led to the necessity to create a separate unit (Div-Ex) to expedite several digital transformation initiatives to be able to support Bank XYZ in competing with other banks. The purpose of this research is to measure and compare the maturity level of both Div-Ex and Div-IT. This research was conducted under a mix-method approach. Team observation was done for both Div-Ex and Div-IT. Subsequently, questionnaires with 69 questions were circulated online to both divisions. Maturity level was assessed by combining Scrum Maturity Method (SMM) to measure current state and Agile Maturity Method (AMM) to evaluate each key process area. Div-IT reached 72,5% largely achieved Maturity Level 2 - Managed, 72.05% largely achieved Maturity Level 3 - Defined, 50% partially achieved Maturity Level 4 - Quantitatively Managed, and 63.89% largely achieved Maturity Level 5 - optimized. Whereas Div-Ex reached 91,25% fully achieved Maturity Level 2, 91.25% fully achieved Maturity Level 3, 50% partially achieved Maturity Level 4, and 77.78% largely achieved Maturity Level 5. In summary, Div-Ex is overall more mature with maturity level 3 whereas Div-IT only maturity level 2. Recommendations for improvement based on Scrum Guide, SBOK Guide, and Praise for Essential Scrum are provided to Bank XYZ to improve the maturity level of the Div-IT.
