OKR template to execute effective decoupling of legacy monolith system

This OKR is centered on the transition from a legacy monolithic system to a more modern microservices architecture. The main objective is to effectively decouple the system, in which one of the specific outcomes outlined is to reduce the number of monolithic components by 30%.

To attain this outcome, certain steps have been proposed such as identifying which components can be redesigned into microservices, implementing and testing the newly created microservices, and developing microservices that replace identified monolithic components. The milestone of this step would be to achieve 90% functionality of these services.

Another aim is to ensure business continuity without interruptions during this transition process. To achieve this, an initiative has been laid out to implement a schedule for regular maintenance and updates, develop comprehensive testing procedures for the new services, and make contingency plans for potential disruptions.

The final aim seeks to equip and fortify the software team to handle these changes. The goal here is to train 75% of the team in modular programming languages. The initiatives for this outcome involve scheduling comprehensive training sessions, conducting evaluations and measurements of progress after said sessions, and identifying team members who may be lacking in skills in modular programming.
