Nothing personal.
To go fast, you want to embrace the Methodology and use the assets out of the box. Trust will enable that speed. Without trust, instead of using the assets, you will be checking whether they're good or not.
In paid projects, we build trust through collaboration, the Methodology is secondary. Former clients refer us, and we prove ourselves at each step.
In a DIY project, you need to build that trust through what is available online. We have not done much work to promote this Methodology (and we do not aim to) so you might be on the fence.
Let us know here what would help build that trust.
We recommend one person in the Team (the Content Lead or Project Lead is probably best suited for it) audits the Methodology and backs it up afterward so that Trust is built internally.
