Investigation, modification, and handover support for systems without specifications.
There is no specification document and no person in charge. For systems developed by other companies, we will organize the approach for investigation of the current situation, modifications, and maintenance handover.
Cannot find the specifications," "Unable to contact the development company," "The person in charge has resigned, and I don't understand the system" — J&C supports the investigation, modification, and maintenance handover of existing systems. We confirm the current system through source code, databases, screens, reports/CSV, logs, server environments, and interviews with users. Even if old documents are available, we will verify them against actual operations. Based on the investigation results, we compare options for continued use, partial modifications, system integration, gradual renewal, and complete migration. We prioritize organizing the information necessary for future maintenance and incident response, leading to a smooth handover. You can consult us even if the documentation is incomplete or if the policies for modifications or renewals have not been decided. We will assess the feasibility and scope based on the available information and investigation results. The published catalog explains "7 pieces of information to confirm," "4 stages of investigation," and "preparations before handover and consultation.
