Learning Objectives
What you need to know and understand
- Know the principles of visual management, Understand the benefits of visual management, Know the range of visual management techniques, Understand how to prepare for the deployment of visual management, Understand how to apply visual management systems in the workplace, Know how to conduct a review of the visual management system, Know how to take forward the visual management system principle
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating an understanding of how visual management aligns with lean principles and reduces waste.
- Look for evidence of a tailored deployment plan considering workplace layout, stakeholder engagement, and training needs.
- Assessors should see clear examples of applied techniques, such as colour-coded floor markings or performance boards, with justification for their use.
- Credit the ability to conduct a structured review using metrics like compliance rates, cycle time reduction, and employee feedback.
- Expect a forward plan that shows how the system will be sustained and improved over time, including ownership and audit processes.
Assessment Guidance
Guidance for achieving higher grades
- 💡Link theoretical principles to concrete workplace examples in your evidence to demonstrate applied understanding.
- 💡When reviewing a system, always suggest incremental improvements tied to data, such as reduced response times or error rates.
- 💡Prepare a clear, step-by-step deployment plan that includes risk assessment and contingency for resistance to change.
- 💡Use the '6S' approach (Sort, Set in order, Shine, Standardise, Sustain, Safety) as a framework to structure your deployment.
- 💡In your evidence, include before-and-after photos or diagrams to visually demonstrate the impact of your visual management improvements.
- 💡Always use correct terminology and define acronyms when first used, e.g., DMAIC, 5S, VSM.
- 💡In calculation questions, show all working steps and include units in your final answer.
- 💡When asked to 'evaluate' or 'discuss', provide balanced arguments with examples from manufacturing contexts.
Common Mistakes
Common errors to avoid in your coursework
- Assuming visual management is only about signage, ignoring other techniques like visual controls and metrics.
- Overlooking the need for employee involvement, leading to systems that are imposed rather than adopted.
- Failing to link visual management to key performance indicators, so it becomes decorative rather than functional.
- Neglecting to standardise visuals across shifts or areas, causing inconsistency and confusion.
- Not reviewing or updating the system post-deployment, resulting in outdated or ignored displays.
- Misconception: Kaizen is only about big changes. Correction: Kaizen focuses on small, continuous improvements that accumulate over time.
- Misconception: 5S is just cleaning. Correction: 5S is a systematic method for organising the workplace to reduce waste and improve productivity, not just tidiness.
- Misconception: Six Sigma is only for statisticians. Correction: While it uses statistical tools, Six Sigma is a problem-solving methodology accessible to all levels with proper training.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on Lean principles and the 7 wastes. Create flashcards for each waste and practice identifying them in case studies.
- 2Week 2: Study 5S and Kaizen. Visit a workplace or watch videos to see real-life applications, then attempt past exam questions on these topics.
- 3Week 3: Learn DMAIC and Six Sigma tools. Practice drawing a fishbone diagram and Pareto chart from given data.
- 4Week 4: Revise calculations (cycle time, efficiency, defect rates) and attempt full past papers under timed conditions.
- 5Week 5: Review examiner feedback and common pitfalls. Focus on weak areas and practice writing model answers.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A manufacturing cell produces 120 units per 8-hour shift, with a planned downtime of 30 minutes for breaks. Calculate the cycle time per unit in minutes, and then determine the number of units that would be produced if the cell operated at 85% efficiency.
- 1.Step 1: Calculate available working time: 8 hours × 60 minutes = 480 minutes. Subtract planned downtime: 480 – 30 = 450 minutes.
- 2.Step 2: Calculate cycle time: 450 minutes ÷ 120 units = 3.75 minutes per unit.
- 3.Step 3: Calculate effective time at 85% efficiency: 450 × 0.85 = 382.5 minutes.
- 4.Step 4: Calculate units produced at 85% efficiency: 382.5 ÷ 3.75 = 102 units.
Question: A process has a defect rate of 2%. If 500 units are produced, how many defects are expected? Then, if a Kaizen event reduces defects by 40%, what is the new defect rate and the new number of defects?
- 1.Step 1: Calculate initial defects: 2% of 500 = 0.02 × 500 = 10 defects.
- 2.Step 2: Calculate reduction: 40% of 10 = 4 defects eliminated.
- 3.Step 3: New defects = 10 – 4 = 6 defects.
- 4.Step 4: New defect rate = (6 ÷ 500) × 100 = 1.2%.
