A work graph consists of the units of work (tasks, ideas, clients, goals, agenda items); information about that work (relevant conversations, files, status, metadata); how it all fits together; and then the people involved with the work (who’s responsible for what? which people need to be kept in the loop?).
The upshot of the latter data structure is having all the information we need when we need it. Where the enterprise social graph requires blasting a whole team with messages like “Hey, has anyone started working on this yet?”, we can just query the work graph and efficiently find out exactly who’s working on that task and how much progress they’ve made. Where the enterprise social graph model depends on serendipity, the work graph model routes information with purpose: towards driving projects to conclusions.
