However, major system integrators do not handle all processes solely within their own departments. Although we are in charge of requirements definition and design, the actual development and testing is often delegated to subcontractors. Major system integrators also have a large number of projects and are working to get orders, so they don't have enough manpower to have one employee focus on a single project. Partly due to the shortage of manpower, secondary and tertiary subcontracting is commonplace in system development sites. The more subcontractors there are, the more the company that ultimately receives the contract will have to work under tighter schedules, budgets, and everything else, which can lead to problems such as ``delivered products not being as expected.

'' To prevent this, one option is to place orders with small and medium-sized system development companies that do not rely on subcontractors from the beginning. At GIG, our in-house development department is always in charge of the requested project, and we Phone Number List form a team that involves internal and external professionals depending on the development content. Point 3: Don't choose a development company based solely on low development costs. When a development company emphasizes ``low development costs,'' it is almost always the case that they cut labor costs when estimating costs. From the perspective of the ordering party, the lower the cost, the better, but if the cost is too low, the quality of the system will deteriorate.





From the author's experience, this was a scratch project for a large company with multiple overseas locations, and we had to develop an extremely large-scale function, and from the perspective of an on-site engineer, the process from . I felt the need to estimate. However, in reality, it only took about two weeks of man-hours. *Man-month: Number of personnel required for one month of development. In the case of 2 person-months, it means that 2 people are required for 1 month of development. If we estimate man-hours that are too far removed from reality, development will not progress as originally planned due to continuous rescheduling. In the end, you may run out of budget and time, and you may not be able to make it to release. This is not limited to system development, but choosing a development company simply because the cost is low is a recipe for failure.
