Questions for you:
- Think of a significant decision your organisation made recently, that affected you. How much of it followed a rational problem-to-solution sequence, and how much was shaped by who happened to be in the room, what proposals were already on the table, and when it occurred?
- Can you think of a good idea in your organisation that has never got traction? What ingredients for a decision have been missing, and how might you get them to collide?
- If you accepted that timing and presence play a larger role in organisational decisions than merit alone, how would that change how you advocate for your own ideas?
Organisational applications:
Managing the bin rather than the process: The Garbage Can model’s practical implication, as the story states, is that you cannot control the whole decision-making process. What you can influence is the quality of what circulates within it. This means ensuring that good ideas are kept visible and accessible rather than presented once and filed away, that the right people are persistently part of the conversations where decisions tend to crystallise, and that choice opportunities, the moments when a decision becomes possible, are recognised and seized rather than deferred.
In practice, this often means separating the work of generating good options from the work of creating the conditions for them to be chosen, treating those as distinct tasks rather than assuming that quality ideas will naturally find their way to decisions.
Timing as a strategic variable: The story notes that a bad idea can succeed because the room was unusually empty, and a good one can fail because the moment never came. This is not simply a complaint about organisational dysfunction; it describes a feature of complex systems with many participants.
One response is to treat timing as something to be managed deliberately. Proposing ideas when key decision-makers have available attention, when adjacent problems have just surfaced that your proposal could address, or when a window of organisational appetite has opened because of external change, tends to produce better outcomes than presenting the same idea repeatedly in identical conditions. Attending to the other streams in the bin, what problems are live, what solutions are competing, and who is currently engaged is more productive than refining the proposal in isolation to its environment.
Using the model to diagnose decision failures: When a decision goes wrong, post-mortems typically focus on the quality of the analysis or the soundness of the choice.
The Garbage Can model suggests a different set of diagnostic questions: which streams were present and which were absent when the decision crystallised? Was the solution attached to the wrong problem? Was the decision made by whoever happened to be available rather than whoever had the relevant knowledge? Did a choice opportunity open and close before the right participants were engaged?
These questions are often more explanatory than “did we have the right data” and point to remedies, process design, stakeholder management, and decision governance rather than to better analysis.
Further reading
On the Garbage Can model and organisational decision-making:
Ambiguity and Choice in Organizations by James G. March, Johan P. Olsen, and Michael D. Cohen. The source text for the Garbage Can model. Academic in register but directly relevant; the original empirical work was done in universities, which makes the examples recognisable to anyone who has worked in a large organisation.
A Primer on Decision Making: How Decisions Happen by James G. March. March’s more accessible account of how decisions actually emerge in organisations, covering the gap between rational choice models and observed behaviour.
On timing, windows, and political opportunity in organisations:
Agendas, Alternatives and Public Policies by John W. Kingdon. Kingdon developed a parallel streams model for understanding how policy decisions happen in government, which maps closely onto the Garbage Can logic. His concept of the “policy window” is the most useful practical framework for understanding when conditions align to make a decision possible.
The Tipping Point by Malcolm Gladwell. A less rigorous but more accessible account of how small factors, including timing, context, and the characteristics of key individuals, determine whether ideas spread or stall.
On rationality, bounded rationality, and how organisations actually choose:
https://en.wikipedia.org/wiki/Thinking,_Fast_and_Slow
by Daniel Kahneman. Kahneman’s account of the limits of rational decision-making provides the individual-level cognitive basis for why organisational decisions deviate from rational models, complementing the structural account the Garbage Can model provides.
Images of Organization by Gareth Morgan. Morgan’s chapter on organisations as political systems and as flux and transformation is useful context for understanding the Garbage Can model within a broader framework of how organisations can be understood.
