When I work in an open office I am always been up to date with what is going on. We have been able to squash problems when they were small because we could overhear people having problems with the systems. Problems that would be too small to bother us with if we are working from home. Communication in the office is quicker, we can get to the root of something fast. People who might known something will overhear and chip in

Lots of small things get fixed and fail to grow into big things

When I work from home I get uninterrupted focus on the task at hand which is something that is almost impossible in the office but only get to hear about problems when they get big and urgent

I also feel that I am dropping out of the loop. There are too many messaging systems that I need to keep an eye on, email, chat, texts, whatsapp, slack to keep in touch. In office communications is basically email for clients or in person

If I have a solid piece of work to do the office is not the best place but only if you can do it by yourself. In the office I can see when I can or cannot interrupt someone. When working from home I have no idea if it is a good time to interrupt someone

But for me the open office is only 12-15 people. Large than that and communications become impossible and the noise to signal get worse. Also managers seem to do more 'managing' in bigger offices :(
