TNS Prognostics measures customer satisfaction. TNS Prognostics' Comparative Customer Satisfaction Surveys and other products and services help companies measure their business performance using the most crucial test of all, the opinions and intentions of their customers. TNS Prognostics helps its clients measure the Loyalty Gap - the difference between how important a particular aspect of the IT customer's ownership experience is and the customer's satisfaction with that aspect. TNS Prognostics takes a consultative approach to every research project, providing insight and analysis based on years of industry experience and our expertise in measuring customer satisfaction and loyalty. TNS Prognostics uses a variety of company-specific factors to customize the design of each client's research study. In addition, we team with our clients, presenting Action Planning Workshops to support data-based decision making to help companies improve business performance.
