Flexibility-Usability-Trade off
Flexibility-Usability Trade off
- As the flexibility of system increase, the usability decrease.
- For example, on Figure 8.3.1, the it shows a screw driver that has nay types of sizes and tip of screw driver. However it has flexibility-usability trade off because it is less efficient.

Flexibility
- As the flexibility of a system increases, the usability decreases.
- Flexibility designs :Able to perform more functions than specialized designs but less efficiently. However, flexible designs are difficult to use as they become more complicated. For example, scientific calculator.

Scientific
calculator is a good example for flexible design because it can compute
complex mathematical calculation such as quadratic equation and matrix
operation when compared to normal calculator that can compute simple
mathematical calculation only such as addition, subtraction, division
and multiplication.
