C3.1.4 Function, Performance and Usability

Function, performance, and usability evaluation is a process used by designers to analyse how well a product works, how efficiently it performs, and how easy it is to use.

This process helps designers identify problems and improve products based on testing, measurements, and user feedback.

The Three Main Areas of Product Evaluation

1. Function

Function refers to the main purpose of a product.

It answers the question:

Does the product perform its intended task correctly?

Function Testing

Function describes the main purpose of a product, while function testing is the process used to verify whether the product performs that purpose correctly. Function testing checks whether the product works properly.

Example: Electric Kettle

Function testing may involve checking whether the kettle can successfully perform its main functions, such as:

• boiling water to the correct temperature,
• automatically switching off after boiling,
• allowing the lid to open and close properly,
• pouring water safely without spilling.

Example of Function Testing Data

Design Improvements from Function Testing

Testing may reveal that the automatic shut-off occasionally fails.

This insight could lead designers to:

• improve the thermostat system,
• redesign safety mechanisms,
• increase reliability.

2. Performance

Performance evaluates how efficiently and effectively a product works.

It answers the question:

How well does the product work?

A product may function correctly but still perform poorly.

Performance Testing

Performance testing measures:

• speed,
• efficiency,
• durability,
• energy consumption,
• reliability under different conditions.

Example: Electric Kettle

Performance testing may include:

• measuring boiling time,
• testing energy efficiency,
• durability testing through repeated use cycles.

Example of Performance Data

Design Improvements from Performance Testing

Testing may show that the kettle becomes less efficient with larger water volumes.

This could lead designers to:

• redesign the heating element,
• improve insulation,
• modify the kettle capacity.

3. Usability

Usability refers to how easy, intuitive, and comfortable a product is to use.

It answers the question:

Is the product easy and comfortable to use?

Even if a product functions correctly, poor usability can create frustration for users.

Usability Testing

Usability testing often involves real users interacting with the product.

Designers observe:

• user behaviour,
• difficulties,
• comfort,
• efficiency of interaction.

Example: Electric Kettle

Usability testing may evaluate:

• ease of filling,
• pouring comfort,
• clarity of controls,
• handle ergonomics,
• visibility of indicators.

Example of Usability Problems

Users may struggle to see the water level indicator in low-light conditions.

Possible redesign solutions:

• illuminated water window,
• improved contrast,
• repositioned indicator.

4. Reverse Engineering

Function, Performance, and Usability are areas of product evaluation, while reverse engineering is a method designers use to better understand these aspects in existing products.

Reverse engineering involves disassembling and analysing existing products to understand:

• how they work,
• how they are manufactured,
• what materials are used,
• what design solutions have been implemented.

Why is Reverse Engineering Important?

Designers use reverse engineering to:

• learn from competitors,
• discover innovative solutions,
• identify weaknesses,
• improve their own products.

Example: Electric Kettle

Reverse engineering may reveal:

• more efficient heating elements,
• better insulation materials,
• improved safety systems,
• advanced filter designs.

Design Improvements from Reverse Engineering

A competitor’s kettle may contain a more effective scale filter.

This could inspire designers to:

• redesign their own filter system,
• improve maintenance,
• increase product lifespan.

Summary Table

to improve traction and stability in running shoes.

Result

The redesigned shoes provided:

• improved grip,
• safer movement on wet surfaces,
• better athletic performance,
• increased durability.

C3.1.6 Constructive Discontent

Constructive discontent is an important concept in product design that helps drive innovation and product improvement.

Instead of simply accepting products as they are, designers critically analyse them and ask:

“How could this product be improved?”

It encourages continuous improvement rather than accepting products as “good enough”.

Types of User Needs

Functional Needs

These relate to how well the product performs its task.

Example:

• short battery life,
• weak materials,
• poor durability.

Emotional Needs

These relate to how users feel when interacting with the product.

Example:

• unattractive appearance,
• frustrating experience,
• lack of personalisation.

Experiential Needs

These relate to the overall user experience.

Example:

• uncomfortable use,
• confusing controls,
• difficult handling.

Solution-Oriented Thinking

Constructive discontent does not focus only on identifying problems.

It also focuses on finding solutions and opportunities for improvement.

Problem

Wired earphones become tangled and inconvenient.

Opportunity for Improvement

Development of:

• wireless earbuds,
• Bluetooth headphones,
• compact charging cases.

User-Centred Perspective

Designers must analyse products from the user’s point of view.

Example

An engineer may believe a product works perfectly.

However, users may think the product is:

• too heavy,
• confusing,
• uncomfortable,
• difficult to use.

Continuous Improvement Mindset

Constructive discontent encourages designers to continuously improve products.

Even successful products can be redesigned and enhanced.

Example: Smartphones

Every year smartphones are improved through:

• better cameras,
• improved batteries,
• lighter materials,
• enhanced software,
• new features.

This process happens because companies constantly search for areas of improvement.

Constructive Discontent as a Driver of Innovation

Constructive discontent often leads to major innovations and entirely new product categories.

Example: Vacuum Cleaners

Problems with Traditional Vacuum Cleaners

• heavy,
• difficult to manoeuvre,
• bulky,
• inconvenient cables.

Innovations Created

These problems led to the development of:

• cordless vacuum cleaners,
• stick vacuums,
• robotic vacuum cleaners.

Result

Designers transformed user frustrations into opportunities for innovation.

Difference Between Criticism and Constructive Discontent

Final Idea

Constructive discontent helps designers:
