iterative design

What is the first stage of the product life cycle?

• Introduction

• Growth

• Maturity

• Decline

Which design principle does iterative design primarily focus on?

• Using the same design for each product

• Continuous improvement through testing and feedback

• Minimising costs only

• Increasing aesthetic appeal only

Light dependent resistors (LDRs) are commonly used in circuits to:

• Measure temperature

• Control light intensity

• Detect moisture

• Determine battery life

Which of the following statements about LEDs is true?

• They consume more energy than incandescent bulbs

• They can only emit red light

• They have a longer lifespan than traditional bulbs

• They require a high voltage to operate

During which stage of the product life cycle do sales peak?

• Introduction

• Growth

• Maturity

• Decline

The purpose of conducting a life cycle assessment (LCA) is to:

• Evaluate the environmental impacts of a product throughout its life cycle

• Determine the cost-effectiveness of a product

• Assess the market demand for a product

• Analyze the production efficiency of a product

What does an LDR change in response to?

• Temperature

• Humidity

• Light levels

• Sound

Which of the following is NOT an advantage of using LEDs over traditional light sources?

• Durability

• Cost efficiency

• Heat production

• Energy saving

What is an important step in the iterative design process?

• Finalising the product without feedback

• Testing prototypes and gathering user input

• Ignoring previous designs

• Using only digital mock-ups

The decline stage of the product life cycle is characterised by:

• Increased sales and profits

• Introduction of new competitors

• A reduction in consumer demand

• Major educational campaigns about the product
