What
To find the strengths and limitations of the system-to-be and dimension it accordingly.
How
The dish
Find the strengths and the limitations of the system-to-be and dimension it accordingly.
Ingredients
- all previously produced artefacts
Process
Describe the environment in which the system-to-be will operate. Consider the following aspects, then make a list and determine the importance of each aspect:
- Special environments, such as ships, hospitals, deserts, space, etc.
- High or low temperatures, humidity, etc.
- Mechanical strength. Here considerations about who the users are (children, trained personnel, etc.) is needed and how the system will be used.
- Electromagnetic environments which include unforeseen disturbances, such as lightning, Electro-Static Discharges (ESD) and Electromagnetic Fields (EMF).
- The use (medical, industrial, household, etc.).
- Special legislations. In Europe, common legislation exists. However, outside of Europe, legislation may vary from country to country. In some areas, e.g. within the refrigeration industry, there is special legislation.
- The lifetime of the product.
From this list it should be possible to dimension all parts of the system-to-be.
Always consider the worst-case scenarios. Ask questions such as: "Is it possible that ... will happen? If then, ...?
When these questions are asked, new aspects will be found to consider. Based on experience a company specific check-list may be helpful.
Why
To ensure that the system-to-be fulfils all demands, withstands the environment in which it will operate and is safe to use.
From here Design will be a suitable process to continue with.
