Windows Analysis - What does it mean?

Hi Guys,

New to posting but have been a keen reader for a while. There are some very talented users on here.

So my question is this: What is the accepted practical definition of a Windows Analysis?

So far I have used a few methods involving 'Windows':

1. Float Mapping / 'As-Is' analysis

2. As-Planned Vs As Built review of windows

3. TIA (UK definition) - Impacting the start of each window, adding progress to identify 'concurrent' delay at the end of each window

Is each of the above an accepted form of 'Windows Analysis'? Or does the term have a common understood meaning, say with reference to a TIA/Windows analysis.

Thanks

Alan
