Our support
Background of the request
The client was considering upgrading their Ruby/Ruby on Rails and consulted with us, who have extensive knowledge of Ruby/Rails. Initially, they considered using domestic resources, but they appreciated the cost benefits of using resources from our wholly owned subsidiary in Vietnam compared to domestic resources and the ability to accelerate delivery by concentrating resources. As a result, they decided to use our Vietnamese resources to act as the client’s liaison and handle everything from implementation to testing.
Support details
When upgrading Ruby/Ruby on Rails, we performed the upgrade in stages to reduce risk.
By upgrading in stages, we were able to detect and address bugs and issues early, reducing the risk of them having a major impact on the entire system. It also allowed us to resolve compatibility issues in small steps, which helped maintain system stability.
Issues and Initiatives
Due to the remaining methods deprecated in Rails 5.1, after the upgrade of “Dr. Hiring Navi” there was a problem with the automatic email sent when creating a job posting. In addition, when re-examining after correcting the code, it was discovered that the behavior of the merge method had changed in Rails 7, and the following corrections were made to address this issue.
- Check the merge method in places where it is used in the source code (over 200 places), identify areas that need to be modified, and adjust the SQL in those areas to make them compatible.
- Because the merge method has a wide range of impact, we carefully re-checked the operation of the related parts and fixed the problem.
Support system
In addition to managing task progress using Google Spreadsheet so that the client could understand progress in real time, we held regular weekly meetings to ensure smooth information sharing.
We also created a Q&A sheet that summarized questions for the client during testing, and a sheet that summarized any issues detected during testing, which made information sharing easier and allowed us to respond to any issues without any omissions.
Client reviews
In order to further improve our performance, we ask each company to fill out an evaluation survey every mont. M-Stage also kindly answers the survey every month and has given us high marks.We would like to introduce some of the evaluation comments below.
Client Comments
We made a variety of requests, and we were extremely grateful that you communicated with us in a way that allowed us to work together to find ways to make them a reality. We also believe that the consideration you gave us from the start of the project was a major factor in the safe release of this project.
