, 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. It refers to an idea or problem that cannot be fixed, where there is no single solution to the problem; and "wicked" denotes resistance to resolution, rather than evil. Another definition is "a problem whose

means that it has no determinable stopping point". Moreover, because of complex interdependencies, the effort to solve one aspect of a wicked problem may reveal or create other problems.

, 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; Conklin's defining characteristics are: # 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.

Background

Rittel and Webber coined the term in the context of problems of social policy, an arena in which a purely scientific-engineering approach cannot be applied because of the lack of a clear problem definition and differing perspectives of stakeholders. In their words, 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 view A worldview or world-view or ''Weltanschauung'' is the fundamental cognitive orientation of an individual or society encompassing the whole of the individual's or society's knowledge, culture, and point of view. A worldview can include natural p ...
s 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

(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, Nancy Roberts identified the following strategies to cope with wicked problems: ;Authoritative :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. ;Competitive :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. ;Collaborative :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. A significant advantage of this approach is the creation of a strong information sharing environment. The main problem is the risk that certain ideas, while integral to finding a possible solution, may be too controversial to accept by other involved parties. 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. Another difficulty is that, in some matters, at least one group of people may hold an absolute belief that necessarily contradicts other absolute beliefs held by other groups. Collaboration then becomes impossible until one set of beliefs is relativized or abandoned entirely. 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

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, 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", Robert Knapp stated that there are ways forward in dealing with wicked problems: Examining networks designed to tackle wicked problems in health care, such as caring for older people or reducing

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." According to Horn, the defining characteristics of a social mess are: # 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; #
