On the Laravel News site there's an article posted from Sharon Steed covering some habits of highly productive tech teams including topics like trust, meetings and understanding roles.

There’s always a lot of talk about “culture” on tech teams. And that makes sense: managers generally hire people that will fit in well with the group they’ve assembled because they know there’s more to work than just doing the job. Being able to get along with your coworkers, being reliable, and looking the part are also important. A big part of building a solid company culture is about creating an environment which helps your employees be productive. Unfortunately, a lot of what we do in tech has the opposite effect.

She talks about the role of perks in an effective workforce and how, despite some seeming very nice on the outside, can cause burnout as it encourages longer work hours than normal. From there she moves into some suggestions about "meeting culture" and some of the major drawbacks to meetings (including how they can distract from "real, paying work"). There's a nice flow chart included in the post too that can help you determine if a meeting is really necessary or not. From there she goes on to talk about the other two topics mentioned above - employees knowing and understanding their roles and fostering trust between them through things like delegation and effective listening.
