About Us

Situation Management Systems, Inc. (SMS) was founded in 1976 as an applied behavioral science firm. We are dedicated to the development and delivery of high-quality management and leadership development programs and services that result in sustainable behavior change. Our commitment is to provide training programs that help people and organizations achieve success by offering applicable real-life solutions for challenging real-life situations.

As the original developers of the Positive Power and Influence® Program, our primary focus is Influence and how to use it to meet objectives while building and maintaining relationships. It is where we excel and where we focus our research. We not only teach influence as a foundational skill, but also demonstrate how it supports the implementation of other processes and strategies from a behavioral standpoint. SMS provides training in the subject areas of influence, negotiation, conflict resolution, sales effectiveness, and change management. SMS programs are currently offered in more than 40 countries and over 15 languages.

SMSidentifies critical problems faced by forward-looking organizations and devotes its resources to developing relevant training solutions. Our programs are tailored to meet current and future needs of individuals and the organizations they serve. Whether it is an off-the-shelf program for supervisors or a highly customized program for senior management, we are able to both meet and exceed customer expectations. After all, our business is people and relationships!
