Plays aren't built by one person. If you have a play that you want to create, jot it down and then put it into action. The great thing about Work.software is the play will take shape because we involve your team to articulate what it is they need to know in order to execute that play independently.
A play is meant to help your team move forward without you. Make sure that your play explains why you're doing it, what you're doing, and what resources are available to your team to get the job done. The best Play allows a teammate to be able to execute a task without asking anyone for support.
