A weak signal is a difficult-to-detect piece of information, activity, behavior, or event that may indicate an emerging change or pattern. In facilitation, weak signals reveal group dynamics, perspectives, and relationships that may affect a session or outcome. One occurrence is not a pattern; significance emerges by connecting observations with other signals and information. section 5.4.2
A harmless joke with a serious implication
During a discussion about standard products versus customized solutions, someone clearly rejecting the conversation is a strong signal. Someone joking about joining another team’s Friday drinks seems random, but may indicate disagreement, dissatisfaction, or thoughts of leaving. The facilitator treats it as an observation to explore, not proof of a conclusion. section 5.4.2
Use weak signals while guiding collaborative sensemaking:
- Put perspectives and conflicts on the table so less visible dynamics can become discussable. section 5.4.2
- Listen more than you talk, ask objective questions, and return observations and summaries to the group. section 5.4.2
- In remote sessions, deliberately observe nonverbal communication and adapt structured whiteboard templates to the group’s needs. section 5.5
