The process of developing Excel systems that leverage the advantages of Excel.

Our company has consistent communication between the front desk and system developers. Even those who are inexperienced in system ordering can smoothly place orders for system development.

■What was the process for advancing the development? In the case of Global Payment Co., Ltd. Since the job description is complex, I first organized the series of processes and provided the documentation. After that, we invited you to our office, where we explained the current flow while showing you the operational procedures of the old system, saying, "This is how we are proceeding." The sheet we showed you at that time does not function as a system yet, but it has buttons and a well-organized screen layout. After that, we implemented the program and conducted system verification. The system verification involved checking whether the results matched those of the previously used system while refining the system internally. ■Results since the introduction of the Excel system "Complex tasks have become shareable." The usability is very simple, so by following the procedure manual, tasks can be completed, creating a situation where work can be easily shared. Even if the person in charge is absent, I feel that this system allows others to continue the work.
