Thanks for the feedback Simon, I already mentioned in the blog that first two approaches are not ideal in nature as its introduce a degree of technical debt in platform however its also a reality check that customers like to get value and they plan to go forward with implementing non-IT services as a starting point using core platform and not purchasing additional licenses for HRSD etc.

They can do so with using ITSM, App engine as a starting point but I never meant to recommend to  stand up a HRSD application using app engine.

You then can document these tech debts, plan for a roadmap to set the right foundation in next upsells.

Again, views are personal and based on personal experience, nothing to do with employer.
