Too Long; Didn't Read
I’ve talked about the challenges of building responsive applications in other blog posts (e.g. <a href="https://hackernoon.com/what-to-do-when-things-get-complicated-56fa17de4969" target="_blank">here</a>and <a href="https://medium.com/@terrycrowley/where-have-all-the-hangs-gone-bd4193e2bd62" target="_blank">here</a>). Microsoft Office took a significantly different approach for Word, PowerPoint, and Excel when they built for the modern mobile platforms (WinRT, Android, iOS) compared to the traditional architecture on Win32. I want to talk about what the team did and why they changed the architecture they had been using for several decades. I was leading Office development at the time and was deeply engaged in the design discussions and planning around these issues.
