What is the catchy phrase or an aphorism, or a buzzword, or an idiom with the meaning of looking at something from several different perspectives?
In particular, I am looking for something that is relevant to the context of measuring something using a range of methods.
For example (maybe not the best example), the outside temperature can be gauged:
- Using a thermometer
- Looking outside the window
- Looking at the weather forecast
- Using your own feeling of warmness/coldness
