Companies are trying to save money, improve products, develop new materials and become more efficient. New technologies are developed to positively impact the manufacturing industry and society.

Energy generation and storage have a huge global impact on our lives - from decisions about the use of fossil fuels and their effect on our environment, to the development of cleaner, more-modern ways to create and store energy.

Developments in science and engineering lead to changes in materials technology. There are a range of modern materials with impressive properties, as well as traditional ones such as wood or metal.

Electronic systems can be understood using a systems block approach of input, process and output. This is vital in designing systems to understand how devices are programmed and how they operate.

Mechanical devices can change one form of force to another. All moving parts work on some sort of mechanism.

All materials have physical and working properties. Physical properties are the traits a material has before it is used, whereas working properties are how the material behaves when it is manipulated.

Designers need to ensure their designs are fit for purpose. Making informed material and manufacturing decisions can help ensure materials are conserved and the impact on the environment is reduced.

When a product is developed, consideration should be given to social, economic and environmental issues, such as the materials used, the product life cycle and how it will be recycled or disposed of.

Learning from and evaluating other designs to identify features that could be improved, eg changing materials, can help make a new design more successful or appealing to its target audience.

Designers use iterative design to simulate the design methods used in industry. Designers continually test, evaluate and refine ideas using a variety of methods to ensure designs meet user needs.

There are a variety of techniques, materials and media that designers can utilise while developing their ideas. Each provides a different function and allows designers to communicate ideas effectively.
