14.1 Problem-Solving Models and Techniques

Problem-solving models and techniques are essential tools for tackling complex issues. From structured approaches like IDEAL to creative methods like brainstorming, these strategies help break down problems and generate innovative solutions.

Visual tools like Ishikawa diagrams and mind maps organize ideas, while analytical methods like SWOT analysis provide strategic insights. These techniques empower critical thinkers to approach decision-making systematically and creatively, enhancing their problem-solving abilities.

• IDEAL model consists of five steps to systematically approach problems
  • Identify the problem clearly
  • Define the problem's scope and constraints
  • Explore potential solutions and strategies
  • Act on the chosen solution
  • Look back to evaluate the effectiveness and learn from the process
• Root cause analysis digs deep to find the underlying causes of issues
  • Uses techniques like the "5 Whys" method to probe deeper
  • Aims to address the source of problems rather than symptoms
  • Often visualized using fishbone diagrams or cause-and-effect charts
• Decision trees provide a visual representation of choices and their potential outcomes
  • Branches represent different decision options
  • Leaves show possible consequences or end results
  • Helps quantify the value of outcomes and the probability of different scenarios
  • Useful for complex decisions with multiple variables (investment choices)

Visual Problem-Solving Tools

• Ishikawa diagram, also known as fishbone diagram, organizes potential causes of a problem
  • Main "bone" represents the primary problem or effect
  • Smaller "bones" branch out to show categories of potential causes
  • Commonly used categories include People, Process, Equipment, Materials, Environment, and Management
  • Helps teams brainstorm and categorize all possible contributing factors to an issue

Creative Thinking Techniques

Collaborative Idea Generation

• Brainstorming encourages free-flowing idea generation without immediate judgment
  • Typically conducted in groups to leverage collective creativity
  • Emphasizes quantity over quality in the initial stages
  • Rules include deferring judgment, building on others' ideas, and encouraging wild ideas
  • Can be structured (round-robin) or unstructured (free-for-all)
• Six thinking hats technique, developed by Edward de Bono, promotes parallel thinking
  • Each colored hat represents a different thinking style or perspective
    • White hat: Facts and information
    • Red hat: Emotions and feelings
    • Black hat: Critical judgment and caution
    • Yellow hat: Optimism and benefits
    • Green hat: Creativity and new ideas
    • Blue hat: Process control and organization
  • Encourages participants to adopt different thinking modes deliberately
  • Helps separate emotion from logic and creativity from information

Visual Idea Organization

• Mind mapping creates a visual representation of ideas and their relationships
  • Starts with a central concept or problem at the center
  • Main themes branch out from the center, with subtopics extending from these branches
  • Uses colors, images, and keywords to enhance memory and association
  • Facilitates non-linear thinking and helps identify connections between ideas
  • Can be created individually or collaboratively, digitally or on paper

Analytical Tools

Strategic Analysis Methods

• SWOT analysis evaluates internal and external factors affecting an organization or project
  • Strengths: Internal positive attributes and resources
  • Weaknesses: Internal negative aspects or limitations
  • Opportunities: External factors that could be beneficial if leveraged
  • Threats: External factors that could cause problems or risks
  • Helps in strategic planning and decision-making by providing a comprehensive overview
  • Can be applied at various levels (personal, project, organizational, industry)
• Pareto principle, also known as the 80/20 rule, helps prioritize efforts and resources
  • States that roughly 80% of effects come from 20% of causes
  • Applied in various fields (business, economics, quality control)
  • Helps identify the most significant factors contributing to a problem or outcome
  • Guides decision-makers to focus on high-impact areas for maximum efficiency
  • Examples of application include:
    • 80% of sales coming from 20% of customers
    • 80% of complaints arising from 20% of product issues
