The guide is arranged to look at the funnel and its operational processes from top to bottom with a focus on RevOps Data Quality. If you want to use the whole guide to get a perspective on all the processes at all the stages, great; go from start to finish. If you have a specific area that's in your purview, then you can go straight to that section, see what it has for you, and dip into other parts as needed.
The guide has callouts for the hands-on operations team that needs to know what to build as well as sections geared to executives and operations leaders who need a high-level view of the benefits of what the team is doing.
If you're a RevOps leader, check out the sections called "the business benefits" to see what the downstream impacts will be from the processes.
