Context of the request
The customer was considering upgrading their existing Ruby/Ruby on Rails system and contacted us because of our extensive Ruby/Rails expertise. They initially planned to use domestic resources, but saw cost advantages in using resources from our wholly owned subsidiary in Vietnam, as well as the ability to accelerate delivery by pooling resources. Therefore, we decided to support the entire project, from customer communication to implementation and testing, with our Vietnamese human resources.
Details about your support
To minimize risk during Ruby/Ruby on Rails version upgrades, we have implemented a phased upgrade approach.
This phased approach allows for early detection and resolution of errors and problems, minimizing the risk of significant impact on the entire system.
Furthermore, compatibility issues can be resolved in small steps, contributing to system stability.
π§ Challenges and Initiatives
An issue occurred with the automatic email sent when creating a job posting after completing the “Dr. Recruitment Navi” version upgrade, due to the presence of an outdated method from Rails 5.1. Furthermore, during retesting after debugging the code, it was discovered that the behavior of the merge method had changed in Rails 7, and the following fix was made to address this issue.
- Identify the `merge` method in all 200 or more locations in the source code, localize the areas that need modification, and adapt the SQL statements in those sections to suit the new usage.
- Because the merge approach has a broad impact, we thoroughly reviewed the relevant parts of the code and fixed any issues.
Support system
So that customers could track progress in real time, we managed work progress using Google Spreadsheets and facilitated seamless information sharing through regular weekly meetings.
Furthermore, creating Q&A sheets summarizing customer questions during testing and tables listing issues discovered has made information sharing easier, ensuring no issues are overlooked.
β Customer feedback
To continue to improve operational efficiency, we ask each company to cooperate by completing a monthly assessment survey.
M-Stage has also kindly responded to our survey every month and given us high praise.
We would like to share some excerpts from their reviews.
We have made many requests and are grateful that you have communicated with us in a way that together we can find solutions to fulfill them.
Furthermore, we believe that the thoughtfulness you showed from the beginning of the project was a key factor in helping the project to be released safely.
