How not to design a video conferencing product?

"Can you please stop sharing your screen so that I can share mine?" "I can't see that part of your shared screen because those buttons are overlaid on top." "How can I share my second webcam without stopping the first?" "Can you please say that again? I missed the last part." "It shows only up to nine videos even though I have a very big screen."

Do you ever feel frustrated due to some artificial restriction imposed by the video conferencing product you use? In this informal article, which some will find quite opinionated, I list some annoying product "features" when it comes to video conferencing. 

What do I do as a software architect?

"I am the Architect. I created the matrix. I’ve been waiting for you." -- The Architect

I present my view on what an architect does or should do? And what are the important things to keep in mind in my opinion? 

Topics: Introduction. Making decisions using trade-offs. Research and evaluate technology and tools. Create proof-of-concept of big picture. Systematically divide the goal into smaller solvable problems. Create knowledge base and training for others. Continuous monitoring and improvement of the system. Identify and address disruptive technologies. Conclusions.

What does it take to get things done? Why do some tasks get done quickly while others drag on forever? Is there a science behind it? Or just philosophy?
