Basically, system migration should be regarded separately from ROI because it is a part of equipment maintenance. Our customers are now more focused on ensuring long-term survival by investing to increase productivity and seeking to minimize production losses. Similarly, customers are looking everywhere for ways to improve profits, even in system migration projects. Yokogawa believes that a system migration can be a very effective step forward in modernizing your plant, and offers a value-added system migration service to make this a reality.

The value-added migration process consists of the following phases:

- Feasibility study that analyzes the gap between targeted and actual results, identifies bottlenecks, proposes practical countermeasures, and estimates the resulting improvement in profits

- Implementation of system migration countermeasures

Yokogawa’s experienced specialists are involved in all phases of this process.
