Sensemaking in Organizations

At Mann Gulch, a survivable action could not become a shared account

On August 5, 1949, fifteen U.S. Forest Service smokejumpers parachuted into Montana's Mann Gulch, where ranger James Harrison was already working a wildfire. The fire crossed below them, cutting off the route toward the Missouri River. The sixteen men turned uphill. Wind, grass, heat, and slope accelerated the fire until it was gaining faster than they could climb. Thirteen died; foreman Robert “Wag” Dodge and two smokejumpers survived.¹

Dodge survived by doing something the crew had not been trained to recognize. He stopped, lit the grass in front of him, waited for the new fire to burn a patch, and lay in its ashes while the main fire passed around it. He tried to bring the others into the burned area. They continued toward the ridge; only two made it over. A Forest Service technical reconstruction models the final twenty minutes as a race the crew could not win. It establishes the material severity of the fire. It does not by itself explain why Dodge's improvisation saved only Dodge.²

Karl Weick used that gap in his 1993 Mann Gulch analysis, which became a central route into Sensemaking in Organizations. His claim is not that language caused the blowup or that a better story could erase the slope. It is that the crew's capacity to organize action disintegrated as the situation stopped matching the roles, tools, and experience through which it had been intelligible.³

Dropping tools disrupted both weight and identity

A smokejumper carried tools because the group had arrived to fight a fire. Dodge's order to drop them was materially sensible: axes, saws, packs, and other equipment slowed the climb. In Weick's reading, it was also an identity shock. If the men were no longer equipped firefighters moving toward a fire line, what were they, and which rule now organized the group? The order arrived while the crew was already shifting from suppression to escape and from formation to individual flight.⁴

That is what identity contributes to sensemaking. “Who are we here?” is not a philosophical preface to action. It helps determine which cue matters and which instruction is credible. Dodge saw a patch he could burn before the main front arrived. To crew members running through flame and noise, a foreman lighting another fire could look like further danger rather than a refuge. His action enacted evidence—a burned area with no fuel left—but the evidence did not carry a shared meaning in time.⁵

Weick calls the event a collapse because the normal sources of order failed together. Retrospectively, the escape fire forms a coherent survival story. Prospectively, the crew had seconds, incomplete perception, and no familiar name for what Dodge was doing. Plausibility therefore matters: people often need an account credible enough to coordinate before accuracy can be complete. Mann Gulch adds the necessary limit. In an irreversible crisis, a plausible account that does not fit fire behavior still kills, and an accurate innovation that cannot become socially intelligible may not coordinate anyone.⁶

The book turns a disaster into a theory of organizing

Published in 1995, the book responds to organization theory's emphasis on decision making and strategic rationality. Weick asks what happens earlier: how an equivocal flow becomes a situation about which a decision can be made. People look back, extract cues, negotiate a story, act, and then encounter a world partly changed by that action. Identity, retrospection, social exchange, ongoing activity, cues, enactment, and plausibility are the book's seven familiar properties, but Mann Gulch shows why they belong together. ⁷

The case is an interpretation, not direct observation. Weick worked from Norman Maclean's reconstruction and fire records decades after the deaths. The Forest Service's current history of Mann Gulch also traces institutional consequences—fire-behavior research, standard orders, and training—that followed the tragedy. Those changes are evidence that the agency learned from the fire; they are not a direct test that Weick's seven properties caused the breakdown. The firefighters and their families deserve that distinction. Their deaths are more than an elegant illustration.⁸

Later fieldwork made control and contest more visible

The book's vocabulary generated a large research program, but its dramatic cases can make sensemaking appear to begin only when a world collapses. Sally Maitlis's later longitudinal study followed ordinary issues in three British symphony orchestras. She found different forms of sensemaking depending on how strongly leaders and stakeholders tried to shape others' accounts. Some processes were guided; others were fragmented, restricted, or minimal. Meaning did not simply emerge from available cues. Participation and control affected which account and action could form.⁹

That evidence extends and complicates Weick. A stakeholder may understand a situation clearly yet lack the position to make their account authoritative. A leader can animate inquiry or narrow it through “sensegiving.” The institutional setting—employment, expertise, hierarchy, professional identity, and access to a forum—shapes who can define plausibility. Weick, Kathleen Sutcliffe, and David Obstfeld later restated the perspective with more attention to action, emotion, persuasion, power, and organizing. That is a documented revision within the tradition, not proof that the 1995 account already contained every later answer.¹⁰

The same distinction matters in Managing the Unexpected. High-reliability organizing needs people who notice weak cues and revise a story, but it also needs material expertise, usable authority, and practiced ways to make an unfamiliar instruction credible. Mann Gulch leaves a demanding question: before the next breakdown, can an organization build identities and relationships that remain flexible enough to recognize a new reality without making every voice, experiment, or provisional story equally safe to trust?¹¹

The links to executive attention, information, and organizational sensing, culture, informal organization, trust, and voice, organizational ignorance, organizational intelligence, and benefit for all life are editorial reading paths for testing who notices, speaks, is believed, learns, and bears risk. They are not claims that Weick used those later formulations.¹²
