Product & Projects
Section titled “Product & Projects”Overview
Section titled “Overview”Product development and project management are critical capabilities for bringing new products and services to market. This topic covers both the design process (QFD, Concurrent Engineering) and project execution approaches (Waterfall, Agile). Understanding these frameworks helps organizations choose the right approach based on product characteristics, requirement stability, and time pressures.
Building a new product is like planning a big school project:
QFD (Quality Function Deployment) = Asking your classmates what they want BEFORE you build it
- Kids say: “We want a cool, easy-to-use, colorful toy!”
- You translate: “Cool” = has lights, “Easy” = one button, “Colorful” = 5 bright colors
- Now you know EXACTLY what to build!
Concurrent Engineering = Everyone works TOGETHER from the start
- Old way (Over the Wall): Designers draw it → throw it “over the wall” to builders → builders say “This can’t be built!” → back to square one
- New way (Concurrent): Designers + builders + painters all work together from day one → fewer problems!
Waterfall = Following a recipe step-by-step
- Step 1: Read whole recipe → Step 2: Buy ingredients → Step 3: Mix → Step 4: Bake → Step 5: Eat
- Problem: Can’t go back! If you forgot sugar, too late!
Agile = Cooking in small batches and tasting as you go
- Make a little → taste → adjust → make more → taste again
- Good: Can fix mistakes early
Core Concept
Section titled “Core Concept”Product development involves two key decisions:
- How to capture customer needs? → QFD (Quality Function Deployment) translates voice of customer into design specifications
- How to organize the development process? → Choose between Sequential (Waterfall) vs. Iterative (Agile) vs. Simultaneous (Concurrent Engineering)
QFD ensures the product reflects what customers value. Concurrent Engineering speeds development by having cross-functional teams work simultaneously. Waterfall provides structure for well-understood products. Agile enables adaptation for uncertain requirements.
Components / Framework
Section titled “Components / Framework”| Framework | Purpose | Key Characteristic | Source |
|---|---|---|---|
| QFD | Translate customer wants to design specs | Voice of Customer → House of Quality | Chapter3.pptx, Slide 22-24 |
| Concurrent Engineering | Speed development through collaboration | Simultaneous, not sequential | Chapter3.pptx, Slide 26 |
| Waterfall | Sequential product development | Six phases, one after another | Chapter3.pptx, Slide 9-15 |
| Agile | Iterative development with learning | Build-Test-Learn cycles | Chapter3.pptx, Slide 17 |
Example
Section titled “Example”QFD Example (Auto Industry): Customer expectations → Customer requirements → Vehicle specifications
- Customer: “Car door should feel solid at highway speeds”
- Requirement: “Door should close with satisfying sound”
- Engineering: Door weight, seal tightness, latch specifications
Concurrent Engineering Example: Traditional: “We design it, you build it” (over the wall) Concurrent: “Let’s work together simultaneously”
Implications
Section titled “Implications”- QFD: Ensures product design reflects customer value, reduces redesign (Toyota: 60% cost reduction)
- Concurrent Engineering: Reduces development time by up to 80%
- Waterfall: Best for stable requirements (sporting goods, furniture, tools)
- Agile: Best for uncertain requirements, enables learning through iteration
Related Concepts
Section titled “Related Concepts”- Design for Manufacturing (DFM): Designing products that are easy to manufacture
- Rapid Prototyping: Building quick prototypes to test and learn
- Cross-functional Teams: Teams with members from multiple disciplines
- Voice of Customer (VOC): Customer needs stated in their own words
Quick Summary
Section titled “Quick Summary”| Concept | Key Idea | When to Use |
|---|---|---|
| QFD | Voice of Customer → Design Specs | When customer needs must drive design |
| Concurrent Engineering | Simultaneous development | When speed to market is critical |
| Waterfall | Sequential phases | When requirements are stable |
| Agile | Iterative cycles | When requirements are uncertain |
Key Concepts Summary:
- QFD = Voice of Customer → Design
- Concurrent = Simultaneous
- Waterfall = Sequential
- Agile = Iterative
Exam Tips:
- QFD STARTS with customer (not engineering)
- Concurrent = SIMULTANEOUS work (not sequential handoffs)
- Waterfall = 6 phases in order (can’t go back)
- Agile = Build-Test-Learn cycles (high/medium priorities first)
