Managed does not mean unowned
A managed platform can take on infrastructure responsibilities while the customer retains application behaviour, authorised data use and outcome review. Hybrid and self-managed deployments change that allocation. Neither label establishes security, compliance or better economics.
Compare a consistent period
Write down fixed monthly operating cost and variable cost per completed task for each candidate. Keep volume, quality and service expectations consistent. A cost crossover is only the intersection of the supplied lines; it does not include migration effort, contract terms, capacity limits or differences in risk.
Use the model as a question generator
The Operating Model tool computes those lines and pairwise crossovers. Ask whether each model has credible staffing, identity, release, incident and change-control arrangements. Cost is one comparison dimension. The final choice needs engineering, procurement and business review.
