There are two ways to do anything:
- The wrong way
- and my way 🙂
There are different types of questions:
- Questions of faith,
such as „Does God exist?“.
- Questions of opinion,
such as „Who is the greatest baseball player of all times“.
- Debate questions,
such as „Should abortion be legal“.
- Questions that can be answered to a degree of certainty by the application of scientific method, which are called empirical questions – in other words, those can be largely settled by the evidence.
Lets stick to the latter, define the requirements and limitations known and validate our opinions and assumptions via a test (ex: create executable architecture alternatives).
