The list of desired properties will continue to expand (and many properties may not end in ility!!). Here is a list of the properties that may become increasingly important in the future - -
- Usability or operability - - These are old ilities, but increasingly complex systems will require a greater focus and appreciation of human factors and ergonomics-type issues.
- Flexibility - - The ability to change into different configurations that allow a particular system to perform multiple functions.
- Extensibility - - The ability to take small networks and expand them into larger ones.
- Resilience - - Not a pure ilities, but critical in a high-risk world. Resilience is the degree to which a system can recover quickly from a major disruption while regaining - - or even exceeding - - its original level.
- Interoperability - - A system property that allows a particular system or product to function independently in their own right but can also work together as a larger whole, even if they are owned and operated by different entities and were not designed originally to work together.
- Compatibility - - How well components of the system can be connected and work together.
- Modularity - - The ability to pull systems apart and then put them back together again.
- Sustainability - - The capacity for a system to endure. In the case of our earth system - - it is the long-term maintenance of responsibility (our very first ility!!).
