The phrase less institutionalized matters. It does not mean chaotic, irrational, or empty of rules. The passengers quickly create expectations about the aisle, information sharing, and assistance. Those rules are temporary, open to revision, and produced in the event. They differ from the transit agency’s written evacuation plan, job descriptions, and chain of command.

Routine organizational behavior begins with more settled roles, authority, and procedures. A conductor making a scheduled announcement follows an institutional role. Riders lining up at a marked platform use an established convention. If the speaker fails and riders appoint one person to relay messages between cars, their improvised coordination moves toward collective behavior.

Spontaneity is a matter of degree. People rarely enter an uncertain scene with no cultural knowledge. They bring habits about helping children, listening to uniforms, protecting personal space, or recording events on phones. Collective behavior develops as those inherited scripts meet a situation they do not completely cover.

Duration alone does not decide the category. A brief graduation ceremony follows a detailed institutional script, while an improvised neighborhood supply network may continue for weeks. The first is routine organized action. The second can begin as collective behavior and later acquire offices, schedules, records, and recognized leaders.

Collective behavior can also occur without physical proximity. During a false online alert, thousands of people may exchange warnings, copy one another, and develop an informal rule about which accounts seem trustworthy. Digital connection changes speed and reach, but the analytic question stays the same. Were settled procedures already directing the action, or did participants have to interpret the situation together?

Power still matters in an improvised setting. A transit employee may gain attention through recognized authority. A passenger with a charged phone controls scarce information. Someone who speaks the dominant language can become an interpreter while other riders struggle to be heard. Temporary order can solve a problem and still distribute influence unevenly.

Collective behavior may disappear, remain informal, or become institutionalized. The passenger relay ends when the train reaches a platform. A disaster kitchen may become a neighborhood nonprofit. Protest marshals may later join a formal social movement organization. The classification describes how action is organized at a particular point, not an unchanging identity for the group.

Institutionalization can be observed as a sequence rather than guessed from duration. After a blackout, residents place extension cords outside and create an improvised phone-charging table. A month later, they elect coordinators, obtain insurance, post eligibility rules, and schedule quarterly drills. The first episode depends on situational adjustment. The later program has durable offices, records, and authorized procedures. If another blackout occurs, volunteers may still improvise, but they now do so inside an organization that existed before the event.

A hybrid case requires evidence about which layer produced the disputed action. Suppose a city emergency office opens an authorized shelter, yet evacuees create an unofficial childcare rotation because the plan assigns no one that task. The shelter opening is routine organizational action. The childcare rule is collective behavior inside that setting. Researchers can compare the written plan, initial assignments, timestamped messages, and later rule changes. If the city eventually adds childcare teams to its official protocol, the improvised solution has become an institutional lesson. This time sequence shows how collective behavior can generate a practice that an organization later adopts without making every action in the shelter spontaneous.

Quick review: Ask how settled the rules, roles, and authority were when action began. Routine organization follows established procedures. Collective behavior develops through a relatively spontaneous response to a shared situation and may create temporary order.
