What is problem-solving?

→ Problem-solving is identifying a problem, understanding its root causes, and finding effective solutions to conquer it.

→ These methods are used to solve the problem.

→ A Problem is an undesirable event.

→ In other words, "Any Gap between what is expected and what is obtained".

→ Any effort to reduce this gap between what is expected and what is obtained is called "Problem-Solving".

Key Steps for Problem Solving:

→ Effective problem-solving techniques require critical thinking and creativity.

→ Sometimes collaborating with team members to develop the best possible solution.

→ It requires the discipline and skills.

⏩Key Steps for Problem-Solving are:

1. Identifying the Issue
2. Analyzing the Issue
3. Generating Possible Solutions
4. Evaluating and Selecting the Best Solution
5. Implementing the Solution
6. Monitoring and Reviewing

01. Identifying the Issue:

→ Identifying the issue is the first and the most crucial step.

→ So we need to define the issues clearly and concisely.

→ A well-identified problem is considered as half a problem solved itself.

→ We can identify issues through the symptoms, such as declining performance, unexpected outcomes, or defect generation.

02. Analyzing the Issue:

→ Analyzing an issue is the process of understanding its nature.

→ Analyzing the issue is more about gathering relevant information, and understanding the context.

→ In this step we need to find out the root causes and their impact.

→ Deep analysis creates the foundation for meaningful solutions.

03. Generating Possible Solutions:

→ Generating possible solutions is the third step.

→ In this step we need to brainstorm and develop various strategies to address the issue.

→ The goal is to identify the best possible solution.

→ This step encourages open-minded thinking where all ideas are considered as a part of the solution.

04. Evaluating and Selecting the Best Solution:

→ The next step is to evaluate and select the best solution.

→ In this step we need to select the best solution after validation of all possible solutions.

→ In this phase, we must select the best solution based on various parameters such as feasibility, cost, impact, and risk.

→ Finally based on feasibility we need to select the practical and effective solution.

→ After assessing the pros and cons of each potential solution.

→ Also we need to consider the potential consequences.

05. Implementing the Solution:

→ Implementing the solution is putting the chosen solution into action.

→ Successful implementation requires careful planning, clear communication, and effective execution.

→ This way we can ensure that the solution is successfully integrated and provides the expected outcomes.

→ This phase is critical because even the best solution can fail if not executed properly.

06. Monitoring and Reviewing:

→ Monitoring and reviewing are the last phases of the problem-solving techniques after the solution implementation.

→ In this step we need to ensure that the implemented solution working as intended resulting us the desired output.

→ We need to track the performance and also identify if any issues occur.

→ Based on the review we need to identify if the problem is resolved completely or not.

Goals of Problem Solving:

→ While we are addressing the problem we need to set clear goals.

→ Setting clear goals helps us to provide direction and motivation to employees.

→ The example of a goal is if we are hungry then our goal is to eat something.

→ The main goal is subdivided into many sub-goals to achieve the main target.

⏩The Goals are:

• Identify the root cause

⏩Four Steps of the PDCA Cycle:

→ P: Plan - Make a plan for improvement - (Identify the issue or area for improvement)

→ D: Do - Carry out the plan - (Implement the plan on a small scale to test its effectiveness)

→ C: Check - Summarize the result - (Analyze the results of the implementation to determine whether the plan achieved the desired outcomes)

→ A: Act - Determine what changes are to be made - (Decide whether to adopt the solution or repeat the cycle)

⏩Key Benefits of the PDCA Cycle:

• Continuous improvement
• Scalable solution
• Data-driven decision making
• Reduces risk
• Increases efficiency
• Adaptable and flexible

⏩Example of PDCA Cycle:

→ Now we will take an example of the manufacturing process.

→ In manufacturing, the PDCA cycle can be used to optimize production lines.

→ So in the planning phase, we can start with identifying the bottlenecks in production.

→ After that in the do phase, we can implement the solution in the pilot area.

→ Then in the check phase, we can measure the performance.

→ The final stage is the act phase, in this phase, we need to roll out the improvements across the entire factory.

→ This will improve the efficiency of the manufacturing process and prevent defects.

→ The PDCA cycle is a very simple and effective method.
