When should one consider using a metamodel in place of an expensive analysis component? I haven't actually seen an example of an openMDAO project that uses metamodels yet, so I was wondering if they're recommended or whether it's still best to treat expensive analyses like normal ones.
Using a metamodel is a trade-off. You trade accuracy vs execution time so it is up to you in your context.

Currently, I'm implementing a Robot framework using the "Page object model".
Kindly let me know if there is another better model.
I would say that the answer depends on what is your system under test (SUT) and how large your test code will be. IMO, page object model is a good choice for SUTs that are systems with many views and you will have a large test automation code base.
If the code base is small, you don't have to think that much about maintainability and code re-usability.

Hi i am making asp.net website
and i am following SDLC Straitegy
so which diagrams are required to draw.
Depends on what diagrams you need!
Diagrams should not be drawn for thr sake of drawing a diagram. It should add value to your development process.
Having said that, You might want to make a Class diagram and a Sequence Diagram for starters. Drawing the overall system architecture wont hurt either.
