1. Performance

Definition: Performance relates to how well a product or service performs its intended function.

  • Key Aspects:
    • Functionality: Does the product/service perform its core functions effectively?
    • Reliability: How dependable is it under specific conditions or over time?
    • Durability: What is its lifespan or how long can it sustain functionality?
    • Speed: How quickly does it perform its tasks or deliver its service?

Example: In smartphones, performance includes processing speed, network reliability, battery life durability, and app functionality.

2. Features

Definition: Features are additional characteristics or capabilities beyond basic performance that add value and distinguish the product/service from competitors.

  • Key Aspects:
    • Additional attributes: What extra functionalities or options does it offer?
    • Customization: Can it be tailored to specific customer needs?
    • Versatility: How adaptable is it to different conditions or uses?

Example: Car features may include navigation systems, safety enhancements, customizable interiors, and entertainment options.

3. Reliability

Definition: Reliability refers to the consistency of performance over time and under varying conditions, and the probability of failure-free operation.

  • Key Aspects:
    • Consistency: How reliably does it deliver expected results?
    • Failure rate: What is the likelihood of malfunction or breakdown?
    • Maintenance: How often is maintenance needed to ensure reliability?

Example: In construction, durability ensures structures endure weather conditions and maintain structural integrity over time.

6. Serviceability

Definition: Serviceability refers to how easily and quickly a product can be repaired or maintained, and the quality of support services provided.

  • Key Aspects:
    • Ease of repair: How straightforward is it to diagnose and fix issues?
    • Availability of parts: Are spare parts accessible, or are there delays?
    • Customer support: How responsive and effective is technical assistance?

Example: In IT, serviceability is crucial for minimizing downtime through prompt technical support and parts availability.

7. Aesthetics

Definition: Aesthetics concerns the sensory appeal of a product/service, including its appearance, feel, sound, smell, and taste.

  • Key Aspects:
    • Visual appeal: How attractive is its design and appearance?
    • Sensory perception: How pleasing is it to touch, hear, smell, or taste?
