This document intends to elucidate the complexity of microservices decomposition and this its inherent process of implementation. Developments in technology and design, achieving higher performance, reliability, or lowering costs are valid reasons to consider controlling the product’s quality by guaranteeing its conformance with established characteristics and standards. Control is made possible by adding quality control, inspection routines, and trend analysis to a manufacturing process. These techniques are established in the Quality field academically and business-wise. Repeat Part Management (RPM) is software that allows users to apply these techniques efficiently and has brought value to the company. However, RPM has been growing, and issues have emerged due to customer needs - accumulated technical debt. These ever-growing modifications are common through different business areas, and architectures’ research evolution has accompanied them. This demand for highly modifiable, rapid development, and independent systems has resulted in the adoption of microservices. There is a concern for existing systems for decomposition due to the characteristics of microservices, which encourages approach/technique research. This architecture promotes legacy system analysis to map current functionalities and dependencies between components. Furthermore, critical concepts in a microservices architecture are researched and implemented in a new system that encompasses Repeat Part Management’s functionalities. This thesis explores the microservices’ architecture evolution with an already defined mature domain in quality assessment.
