15Five is web-based software that improves communication between managers and employees to align goals and uncover obstacles and opportunities that are often missed. 15Five is easy, quick, and automated, using the power of simple questions to reveal important information for business success.

Each week, employees take about 15 minutes to answer a few insightful questions on things like obstacles, achievements, morale, innovation, and trends. Then Managers take five minutes to review and respond—addressing issues recognizing accomplishments, and learning new ideas.

Unlike status reports, anonymous surveys, or even 1 on 1 meetings, 15Five inspires open and honest dialogue that brings to light issues and opportunities that are often missed.
