Design architecture aims

Aspects of software that is engineered to have the following, although some will conflict, and thus a trade off is required. These trade offs and choices of what is a priority change and occur during the lifecycle of a system/application:

• accessibility

• affordability

• compatibility

• customizability

• dependability

• effectiveness

• fault tolerance

• integrity

• mobility

• portability

• provability

• reproducibility

• safety

• securability

• sustainability

• accountability

• agility

• composability

• debugability

• deployability

• efficiency

• fidelity

• interoperability

• modifiability

• precision

• recoverability

• resilience

• scalability

• simplicity

• tailorability

• accuracy

• auditability

• configurability

• degradability

• discoverability

• usability

• flexibility

• learnability

• modularity

• predictability

• relevance

• responsiveness

• seamlessness

• stability

• testability

• adaptability

• autonomy

• correctness

• determinability

• distributability

• extensibility

• inspectability

• maintainability

• operability process

• capabilities

• reliability

• reusability

• self-sustainability

• standards compliance

• timeliness

• administrability

• availability

• credibility

• demonstrability

• durability

• failure transparency

• installability

• manageability

• orthogonality

• producibility

• repeatability

• robustness

• serviceability

• survivability

• traceability

• To improve design to meet design requirements not only depends on the logic of your program, but other factors in the software stack

  • software stack from top to bottom dependencies

    • your programs

    • libraries/api

    • compilers

    • assembler

    • virtualisation

    • operating system

    • hardware

• As everything depends on hardware, improving this despite improving it's dependents can lead to better performance

  • but is an easy way out, but can be exponentially expensive for little gain after a while

  • So design needs to take to deal with other levels first, the higher levels are generally cheaper to fix or improve first
