Problem Solving


Quality Glossary Definition: Problem Solving

Problem solving is the act of defining a problem; determining the cause of the problem; identifying, prioritizing and selecting alternatives for a solution; and implementing a solution.


An organization needs to define some standard of problem solving, so that leadership can effectively direct others in the research and resolution of issues.

In problem solving, there are four basic steps.

1. Define the problem

Diagnose the situation so that your focus is on the problem, not just its symptoms. Helpful techniques at this stage include using flowcharts to identify the expected steps of a process and cause-and-effect diagrams to define and analyze root causes.

The chart below identifies key steps for defining problems. These steps support the involvement of interested parties, the use of factual information, comparison of expectations to reality and a focus on root causes of a problem. What’s needed is to:

  • Review and document how processes currently work (who does what, with what information, using what tools, communicating with what organizations and individuals, in what time frame, using what format, etc).
  • Evaluate the possible impact of new tools and revised policies in the development of a model of “what should be.”

2. Generate alternative solutions

Postpone the selection of one solution until several alternatives have been proposed. Having a standard with which to compare the characteristics of the final solution is not the same as defining the desired result. A standard allows us to evaluate the different intended results offered by alternatives. When you try to build toward desired results, it’s very difficult to collect good information about the process.

Considering multiple alternatives can significantly enhance the value of your final solution. Once the team or individual has decided the “what should be” model, this target standard becomes the basis for developing a road map for investigating alternatives. Brainstorming and team problem-solving techniques are both useful tools in this stage of problem solving.

Many alternative solutions should be generated before evaluating any of them. A common mistake in problem solving is that alternatives are evaluated as they are proposed, so the first acceptable solution is chosen, even if it’s not the best fit. If we focus on trying to get the results we want, we miss the potential for learning something new that will allow for real improvement.

3. Evaluate and select an alternative

Skilled problem solvers use a series of considerations when selecting the best alternative. They consider the extent to which:

  • A particular alternative will solve the problem without causing other unanticipated problems.
  • All the individuals involved will accept the alternative.
  • Implementation of the alternative is likely.
  • The alternative fits within the organizational constraints.

4. Implement and follow up on the solution

Leaders may be called upon to order the solution to be implemented by others, “sell” the solution to others or facilitate the implementation by involving the efforts of others. The most effective approach, by far, has been to involve others in the implementation as a way of minimizing resistance to subsequent changes.

Feedback channels must be built into the implementation of the solution, to produce continuous monitoring and testing of actual events against expectations. Problem solving, and the techniques used to derive elucidation, can only be effective in an organization if the solution remains in place and is updated to respond to future changes.

Knowing how to analyze business problems, reconcile different perspectives, decide on a course of action, and persuade others are the key skills to successfully exercising the management profession.

The case method – IESE’s main teaching method – helps students to develop these skills by bringing real-life business problems into the classroom, training them to think and decide like managers.

Whether analyzing challenges faced by a construction company, amusement park, ceramic manufacturer or struggling airline, the case method asks the student to put him or herself in the shoes of the manager: How can I boost flagging sales? How can the company expand its revenue streams given its new competitive environment? What incentive policies might work in an industry with high turn-over?

In contrast to lecture-based teaching methods, here the students do most of the talking. The professor facilitates and guides the discussion, asking questions and eliciting participation from the entire class to enrich the discussion with contrasting viewpoints, different industry experiences, and cultural backgrounds

How it works:

1. Students prepare the case on their own, reflecting on key questions: What is the major problem? What are the alternative courses of action? What would you do if you were the manager in question?
2. Before going to class, students meet with their team to discuss and compare their analysis and contrast viewpoints.
3. The discussion is then taken to the larger classroom context with the professor facilitating a comprehensive discussion of the case.
4. Together the class develops an analysis, evaluates different courses of action with conclusions and key learning points.

The case might be recent or about a dilemma a company faced two decades ago. However the questions highlighted in each case are relevant and universal. After participating in hundreds of case discussions, students leave IESE better prepared to take on the challenges they will face as managers, as decision-makers and as leaders.
