Problem Solving Framework: Production Control Steps

Troubleshooting Bibliographic Reference

Daniel Robert Sippe & Bulfin: Planning and Production Control, Chapter 3

Troubleshooting Problem Definition

Problem: When I expect something to happen and it does not.

Approaches to Resolution

How to Solve:

1. Acquittal: Ignore the issue.
2. Resolution: Use common sense.
3. Solution: Use the USA method (the best answer).
4. Dissolution: Redesign to eliminate the cause.

Participation in the Problem

Who is involved:

• Owners of the Problem: Those who interact with and live with the problem.
• Analysts: Those who study the solutions.

Focus: The Six-Step Problem Solving Process

Step 1: Identification of the Problem

1. Owners of the Problem
2. Analyst
3. Need / Opportunity
4. Overall Purpose:
   • Levels
   • Goals
   • Objectives
5. Assumptions

Step 2: Understanding the Problem

1. System
2. Owners
3. Analyst
4. Assumptions
5. Characteristics of the Problem
6. Validation of the Problem

Step 3: Development of the Model

A simplified representation of reality.

1. Analyst
2. Assumptions
3. Data
4. Concept Modeling
5. Representations
6. Frontiers
7. Objective
8. Restrictions
9. Internal Validation (Analyst)

Types of Models

1. Bidimensional: Graphics and photos.
2. Conceptual: Schemes such as mathematical models (requires knowledge of variables, relationships, and objectives; advantage is reopening them).
3. Iconic: Visual elements such as 3D models.
4. Computer: Mixture between models with 2D graphics in 3D iconic models.

Step 4: Settlement of the Model

1. Analyst
2. Resources
3. Algorithms: Logical, sequential, and iterative steps.
   • Must have positive statements (e.g., "I'm going to Vina").
   • Should not be ambiguous.
   • Should be achievable and attainable.
   • Must have a starting point and ending point.
4. External Validation (Owner): Trial by the owners for problem validation.

Step 5: Interpretation of the Solution

1. Owners
2. Analyst
3. Interpretation
4. Robust Solution: Remains valid despite small changes in data (e.g., clothing size).
5. Validation of the Solution
6. Trial: Acceptance or Rejection

Step 6: Implementation

1. Owners
2. Analyst
3. Presentation (to those involved)
4. Acceptance and Commitment
5. Training
6. Parallel Operation
7. Feedback (Make adjustments; avoid early return to the solution phase)
