Flashcards for Quick Revision

As the exam nears, heavy textbooks and lengthy notes aren’t your best friends. What you need is a way to quickly jog your memory and test your understanding. Enter flashcards! These pocket-sized powerhouses are ideal for last-minute revisions. Here’s how to make the most out of them.

Tips on Creating or Using Existing Flashcards

  1. Simplicity is Key: Each card should represent one idea, fact, or concept. Keep the information concise.
  2. Use Visuals: Where possible, include diagrams or doodles that can help you remember the information more vividly.
  3. Categorize: Sort your flashcards into different piles based on the DMAIC methodology or the specific subject matter. This can help you target your weak areas.
  4. Interactive Elements: If you’re making digital flashcards, consider incorporating interactive elements like quick quizzes or clickable infographics.
  5. Review, Shuffle, Repeat: Don’t just go through the cards once. Shuffle them and go through them multiple times to reinforce your memory.

Highlight Key Metrics, Statistical Tools, and Lean Principles

When you’re close to the exam, you should focus on the most crucial elements of Lean Six Sigma, such as:

  • Key Metrics: Cards for metrics like Defects Per Million Opportunities (DPMO), Process Sigma, and Cost of Poor Quality (COPQ) are a must.
  • Statistical Tools: Don’t forget flashcards on tools like Pareto Charts, Control Charts, and Fishbone Diagrams. Understanding these tools is crucial for both the exam and real-world applications.
  • Lean Principles: Cover the core principles like ‘5S’, ‘Just-In-Time’, and ‘Voice of the Customer’ to make sure you’re well-rounded in your understanding.

Flashcards are a powerful tool for last-minute revision. They help you focus on the key points that are often the difference between passing and failing. They’re also portable, making it easy to revise on the go, anytime, anywhere.
