A wicked problem is a problem that is difficult or impossible to solve because of incomplete, contradictory, and changing requirements that are often difficult to recognize. The use of the term "wicked" here has come to denote resistance to resolution, rather than evil. Moreover, because of complex interdependencies, the effort to solve one aspect of a wicked problem may reveal or create other problems.
The phrase was originally used in social planning. Its modern sense was introduced in 1967 by C. West Churchman in a guest editorial he wrote in the journal Management Science, responding to a previous use of the term by Horst Rittel. Churchman discussed the moral responsibility of operations research "to inform the manager in what respect our 'solutions' have failed to tame his wicked problems". Rittel and Melvin M. Webber formally described the concept of wicked problems in a 1973 treatise, contrasting "wicked" problems with relatively "tame", soluble problems in mathematics, chess, or puzzle solving.
Rittel and Webber's 1973 formulation of wicked problems in social policy planning specified ten characteristics:
- There is no definitive formulation of a wicked problem.
- Wicked problems have no stopping rule.
- Solutions to wicked problems are not true-or-false, but good or bad.
- There is no immediate and no ultimate test of a solution to a wicked problem.
- Every solution to a wicked problem is a "one-shot operation"; because there is no opportunity to learn by trial and error, every attempt counts significantly.
- Wicked problems do not have an enumerable (or an exhaustively describable) set of potential solutions, nor is there a well-described set of permissible operations that may be incorporated into the plan.
- Every wicked problem is essentially unique.
- Every wicked problem can be considered to be a symptom of another problem.
- The existence of a discrepancy representing a wicked problem can be explained in numerous ways. The choice of explanation determines the nature of the problem's resolution.
- The social planner has no right to be wrong (i.e., planners are liable for the consequences of the actions they generate).
Conklin later generalized the concept of problem wickedness to areas other than planning and policy.
- The problem is not understood until after the formulation of a solution.
- Wicked problems have no stopping rule.
- Solutions to wicked problems are not right or wrong.
- Every wicked problem is essentially novel and unique.
- Every solution to a wicked problem is a 'one shot operation.'
- Wicked problems have no given alternative solutions.
Classic examples of wicked problems include economic, environmental, and political issues. A problem whose solution requires a great number of people to change their mindsets and behavior is likely to be a wicked problem. Therefore, many standard examples of wicked problems come from the areas of public planning and policy. These include global climate change, natural hazards, healthcare, the AIDS epidemic, pandemic influenza, international drug trafficking, nuclear weapons, nuclear energy, waste and social injustice.
Rittel and Webber coined the term in the context of problems of social policy, an arena in which a purely scientific-rational approach cannot be applied because of the lack of a clear problem definition and differing perspectives of stakeholders. In their words, "The search for scientific bases for confronting problems of social policy is bound to fail because of the nature of these problems...Policy problems cannot be definitively described. Moreover, in a pluralistic society there is nothing like the indisputable public good; there is no objective definition of equity; policies that respond to social problems cannot be meaningfully correct or false; and it makes no sense to talk about 'optimal solutions' to these problems... Even worse, there are no solutions in the sense of definitive answers."
Thus wicked problems are also characterised by the following:
- The solution depends on how the problem is framed and vice versa (i.e., the problem definition depends on the solution)
- Stakeholders have radically different world views and different frames for understanding the problem.
- The constraints that the problem is subject to and the resources needed to solve it change over time.
- The problem is never solved definitively.
Although Rittel and Webber framed the concept in terms of social policy and planning, wicked problems occur in any domain involving stakeholders with differing perspectives. Recognising this, Rittel and Kunz developed a technique called Issue-Based Information System (IBIS), which facilitates documentation of the rationale behind a group decision in an objective manner.
A recurring theme in research and industry literature is the connection between wicked problems and design. Design problems are typically wicked because they are often ill defined (no prescribed way forward), involve Stakeholders with different perspectives, and have no "right" or "optimal" solution. Thus wicked problems cannot be solved by the application of standard (or known) methods; they demand creative solutions.
Strategies to tackle wicked problems
Wicked problems cannot be tackled by the traditional approach in which problems are defined, analysed and solved in sequential steps. The main reason for this is that there is no clear problem definition of wicked problems. In a paper published in 2000, Roberts identifies the following strategies to cope with wicked problems:
- These strategies seek to tame wicked problems by vesting the responsibility for solving the problems in the hands of a few people. The reduction in the number of stakeholders reduces problem complexity, as many competing points of view are eliminated at the start. The disadvantage is that authorities and experts charged with solving the problem may not have an appreciation of all the perspectives needed to tackle the problem.
- These strategies attempt to solve wicked problems by pitting opposing points of view against each other, requiring parties that hold these views to come up with their preferred solutions. The advantage of this approach is that different solutions can be weighed up against each other and the best one chosen. The disadvantage is that this adversarial approach creates a confrontational environment in which knowledge sharing is discouraged. Consequently, the parties involved may not have an incentive to come up with their best possible solution.
- These strategies aim to engage all stakeholders in order to find the best possible solution for all stakeholders. Typically these approaches involve meetings in which issues and ideas are discussed and a common, agreed approach is formulated.
In his 1972 paper, Rittel hints at a collaborative approach; one which attempts "to make those people who are being affected into participants of the planning process. They are not merely asked but actively involved in the planning process". A disadvantage of this approach is that achieving a shared understanding and commitment to solving a wicked problem is a time-consuming process. Research over the last two decades has shown the value of computer-assisted argumentation techniques in improving the effectiveness of cross-stakeholder communication. The technique of dialogue mapping has been used in tackling wicked problems in organizations using a collaborative approach. More recently, in a four-year study of interorganizational collaboration across public, private, and voluntary sectors by Fischer at the University of Oxford, steering by government was found to perversely undermine a successful collaboration, producing an organizational crisis which led to the collapse of a national initiative.
In Wholesome Design for Wicked Problems, Professor Robert Knapp states that there are ways forward in dealing with wicked problems. "The first is to shift the goal of action on significant problems from "solution" to "intervention." Instead of seeking the answer that totally eliminates a problem, one should recognize that actions occur in an ongoing process, and further actions will always be needed."
Examining networks designed to tackle wicked problems in health care, such as caring for older people or reducing sexually transmitted infections, Ferlie and colleagues suggest that managed networks may be the 'least bad' way of "making wicked problems governable".
Problem structuring methods
A range of approaches called problem structuring methods (PSMs) have been developed in operations research since the 1970s to address problems involving complexity, uncertainty and conflict. PSMs are usually used by a group of people in collaboration (rather than by a solitary individual) to create a consensus about, or at least to facilitate negotiations about, what needs to change. Some widely adopted PSMs include soft systems methodology, the strategic choice approach, and strategic options development and analysis (SODA).
Messes and social messes
Russell L. Ackoff wrote about complex problems as messes: "Every problem interacts with other problems and is therefore part of a set of interrelated problems, a system of problems…. I choose to call such a system a mess."
Extending Ackoff, Robert Horn says that "a Social Mess is a set of interrelated problems and other messes. Complexity—systems of systems—is among the factors that makes Social Messes so resistant to analysis and, more importantly, to resolution."
- No unique "correct" view of the problem;
- Different views of the problem and contradictory solutions;
- Most problems are connected to other problems;
- Data are often uncertain or missing;
- Multiple value conflicts;
- Ideological and cultural constraints;
- Political constraints;
- Economic constraints;
- Often a-logical or illogical or multi-valued thinking;
- Numerous possible intervention points;
- Consequences difficult to imagine;
- Considerable uncertainty, ambiguity;
- Great resistance to change; and,
- Problem solver(s) out of contact with the problems and potential solutions.
Divergent and convergent problems
E. F. Schumacher distinguishes between divergent and convergent problems in his book A Guide for the Perplexed. Convergent problems are those for which attempted solutions gradually converge on one solution or answer. Divergent problems are those for which different answers appear to increasingly contradict each other all the more they are elaborated, requiring a different approach involving faculties of a higher order like love and empathy.
Wicked problems in software development
In 1990 DeGrace and Stahl introduced the concept of wicked problems to software development. In the last decade, other computer scientists have pointed out that software development shares many properties with other design practices (particularly that people-, process-, and technology-problems have to be considered equally), and have incorporated Rittel's concepts into their software design methodologies. The design and integration of complex software-defined services that use the Web (web services) can be construed as an evolution from previous models of software design, and therefore becomes a wicked problem also.
Super wicked problems
Kelly Levin, Benjamin Cashore, Graeme Auld and Steven Bernstein introduced the distinction between "wicked problems" and "super wicked problems" in a 2007 conference paper, which was followed by a 2012 journal article in Policy Sciences. In their discussion of global climate change, they define super wicked problems as having the following additional characteristics:
- Time is running out.
- No central authority.
- Those seeking to solve the problem are also causing it.
- Policies discount the future irrationally.
While the items that define a wicked problem relate to the problem itself, the items that define a super wicked problem relate to the agent trying to solve it. Global warming is a super wicked problem, and the need to intervene to tend to our longer term interests has also been taken up by others, including Richard Lazarus.
