We would like to introduce a case study of a shrine management system project commissioned by Iosis Co., Ltd. Although there was prior experience in building another shrine management system, we were approached due to the high costs of the relevant vendor and decided to take on the project. We conducted a skill transfer to the vendor's staff by March 2024, and from April 2024 onwards, the vendor has been handling maintenance independently. There were significant troubles in the upstream processes, such as fixing specifications after the planned release date, which resulted in a larger budget relative to the project's scale. Documentation was accumulated in Confluence, and the repository was transferred. Since the customer lacked knowledge in AWS and PHP during the handover, we also provided training alongside maintenance. [Case Overview] - Start Date and Duration: November 2022 - June 2023 - System Scale: 10 person-months (80 million yen) - System Overview: Shrine Management System - Keywords: AWS, PHP-Laravel, React.js, MySQL, Github *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of a commissioned project for a POS (Point of Sale) system for beauty salons, handled by Iosis Co., Ltd. Two years have passed since the system launch, but there are still many unresolved issues, and the vendor's response has been poor, leading the user side to decide to change vendors. After receiving inquiries from other vendors who could not provide support linguistically, Iosis conducted an investigation and determined that we could provide support. At the vendor's request, the handover was gradually redone over the course of a year. During this process, the areas of responsibility were gradually transferred to Iosis, and the transfer was completed. After that, we regularly implemented updates such as migrating the infrastructure from Heroku to AWS and adding new features. 【Case Overview】 ■ Start Date and Duration: April 2019 - December 2021 (currently still providing maintenance support) ■ System Scale: 25 person-months (20 million yen) ■ System Overview: POS system for beauty salons ■ Keywords: AWS, Ruby on Rails, React.js, MySQL, GitHub *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study of a project commissioned by a tutoring company that was handled by Iosis Co., Ltd. This project developed from an SES project that had been under maintenance for about 1.5 years. Originally, it was a project ordered to a different vendor, but a vendor change was decided due to the user's intention. Initially, it involved partial function development, but the quality of the assigned areas was high and the schedule was always ahead of time, so ultimately, we were asked to handle the entire production. There were about 90 specification deficiencies that were discovered after the order was placed, but we absorbed those as well. Since we were able to deliver ahead of schedule, we also provided technical training for the internal SE of the tutoring company, created manuals, and supported maintenance planning. [Case Overview] ■ Existing System Replacement Development ■ Start Date, Duration: April 2023 - September 2024 (Maintenance support planned for the future) ■ System Scale: 350 person-months (approximately 295 million yen) ■ System Overview: Core system for tutoring operations ■ Main Development: Agile development ■ Keywords: AWS, React.js, Go-Echo, Github, Sendgrid *For more details, please download the PDF or feel free to contact us.

• Process Control System

We would like to introduce a case study of a project commissioned by a construction company that was handled by IoSys Co., Ltd. At the customer's request, we developed the system from scratch. The project encompassed a wide range of functionalities including customer management, contract management, construction management, and sales management. However, since the requirements were clearly defined, we only needed to address the work from the basic design phase onward. Additionally, the user side took care of all infrastructure-related aspects, which resulted in the system being completed on a significantly low budget relative to its scale. In addition to this, our company has experience with: - "Function development for core systems due to vendor change" - "Numerous bugs and renovation projects for remote office management systems" These cases have been adopted by companies facing various issues related to their systems. Please feel free to contact us when you need our services. 【Case Overview】 ■ Start Date, Duration: October 2019 - March 2022 ■ System Scale: 11 person-months (8.8 million yen) ■ System Overview: Sales, construction progress, and sales management system for a construction company ■ Keywords: AWS, PHP-Laravel, MySQL, Github *For more details, please download the PDF or feel free to contact us.
