What Is a “Just Do It” Project in Lean Six Sigma?
Learn when to use the “Just Do It” (JDI) methodology for your Lean Six Sigma certification. Discover why JDI is best suited for small, simple projects with obvious solutions that require quick fixes without the extensive analysis of a full DMAIC project.
Question
Which type of projects are best suited for the “Just Do It” methodology?
A. Small, simple projects that need quick solutions
B. Projects that involve product design from scratch
C. Projects requiring complex statistical models
D. Large-scale projects with high complexity
Answer
A. Small, simple projects that need quick solutions
Explanation
“Just Do It” addresses quick fixes without extensive analysis. The “Just Do It” (JDI) approach is designed for problems where the issue is straightforward, the solution is obvious, and implementation can be done quickly without the need for a formal, data-intensive project.
Understanding the “Just Do It” Approach
“Just Do It” projects, sometimes referred to as “quick wins,” are improvements that do not require the rigorous, five-phase DMAIC (Define, Measure, Analyze, Improve, Control) framework. The JDI methodology is applied when a problem’s cause and solution are already known and can be implemented with minimal resources and risk. These are typically small-scale issues identified by employees during their daily work that can be resolved quickly to yield immediate benefits. The key is that extensive data analysis is not needed because the path forward is clear.
When to Use “Just Do It” vs. DMAIC
Choosing the right methodology is critical for efficient problem-solving.
Use “Just Do It” when:
- The problem is simple and well-understood.
- The solution is obvious and has been confirmed.
- The fix can be implemented quickly (e.g., within a day or a few hours).
- The risk of implementation is low.
- The resources required are minimal.
Use DMAIC when:
- The problem is complex, and the root cause is unknown.
- The risks associated with the problem are high.
- Data is required to understand the problem and validate solutions.
- The project requires significant resources and cross-functional team involvement.
A simplified version of DMAIC, sometimes called DPIC (Define, Plan, Implement, Control), can be used for JDI projects to provide some structure without the full analytical burden of the Measure and Analyze phases.
Analysis of Incorrect Options
B. Projects that involve product design from scratch: This is incorrect. Designing a new product or process requires a different, more comprehensive methodology known as Design for Six Sigma (DFSS), which typically follows a DMADV (Define, Measure,Analyze, Design, Verify) framework.
C. Projects requiring complex statistical models: This is the opposite of a JDI project. Problems that require complex statistical analysis are, by definition, not simple and are prime candidates for the full DMAIC methodology, particularly the Analyze phase.
D. Large-scale projects with high complexity: This is incorrect. Large, complex projects with unknown solutions are exactly the types of problems that the structured and data-intensive DMAIC framework was created to solve. Attempting to use a “Just Do It” approach on such a project would likely lead to failure.
