Comparative Effectiveness Analysis

Benchmarking is a very effective method for identifying improvement opportunities by comparing your plant performance with similar plants in the industry. The Yokogawa Comparative Effectiveness Analysis service calculates your performance against production-related key performance indicators (KPIs) and provides a report which can compare your performance against:

- Similar operating plants within your corporate group of companies (if applicable)
- Similar operating plants across the industry (competitors)


This form of benchmarking enables clear identification and prioritization of improvement opportunities based on normalized performance criteria within your industry. Continuous periodical benchmarking is recommended to ensure that companies remain watchful of their competitors' positioning and maintain a culture of continuous improvement.

Industrial automation (IA) infrastructure can be regarded as the baseline for safe and profitable production. Therefore, it is important to do benchmarking. Yokogawa Comparative Effectiveness Analysis lends customers a tool that gathers IA data for automatic calculation of KPIs, which is then used by Yokogawa to create periodical benchmarking reports that are based on a longstanding experience as an IA supplier. This approach has the following advantages:

- Eliminates tedious and time consuming information acquisition/calculation - Compares performance against a rich industry database - Enables problem solving with Yokogawa Solution Implementation Services™ - Utilizes DCS internal parameters (e.g. DCS bus load, number of called panels)


Yokogawa intends to update KPIs regularly to meet customers' changing needs.
