- Iterative design- cyclic approach
- Each iteration of a design is tested and evaluated. changes and refinements are then made.
- E.g Dyson vacuum cleaners- the orginal DC01 was developed as a result of thoudands of different prototypes.
Advantages of iterative design:
- Due to each iteration being tested/evaluated problems are more likely to occur in early stages instead of the final design.
- Encourages a focus on the most criticle aspects of a products design.
- User feedback is constantly being gathered.
Disadvanrtages of iterative design:
- Designers can be too focussed on one iteration they loose sight of the rest of the design,
- It can be very time consuming.
- An approach where the needs and wants of the end user are considered extensively at each stage of the design process.
Advantages of user-centred design
- The end user feels a greater scense of ownership as it is more tailored to suit there needs.
- By listening to the end user at each design stage means the final product will meet the users' needs/expectations.
Disadvanteges of user-centred Design
- Requires extra time to meet and interview users and takes designer time to alter the design based on user feedback.
- Product may not be suitible to sell to a wider audience because it becomes to focused on one user's idea/ preference.
- The systems based approach is often used when designing electronic or mechanical components to design the overview of the system,
- Top-down approach- starts with an overview of the overall system in terms of its input process and output sub-systems. Detaols form individual components of each sub-system are considered later.
Advantages of a systems Approach
- It does not require highly specialist knowledge of electronic or mechanicae components to design the overview of the the system.
- the top down approach makes it easy to communicate how the system will work to non-technical specialists, such as clients.
- The system is designed in blocks, so it is easier to find errors or faults in the design.
Disadvantages of a sysrems Approach
Because of the block based design approach, it can lead to the use of componets that are not necessary.
Can lead to larger costs due to unnecessary componets.
