Architecture decisions, RFPs and vendor evaluation for digital commerce platforms.

Migration should be treated as a controlled business transition with observability, reconciliation and the ability to reverse. The migrations that go quietly are the ones planned around a rollback, not around a launch date.
Replacement is justified when the capability and economic gap exceeds the risk and cost of migration. Migrating too early wastes budget; migrating too late is the more common and more expensive mistake.
The goal is to control critical dependencies and preserve real options where switching cost could constrain strategy. Lock-in rarely announces itself; it shows up later as a decision the business can no longer make.
TCO should model the cost of acquiring, implementing, operating, evolving and leaving the platform under several scenarios. The sticker price is usually the smallest number in the real cost of a platform decision.
The right architecture maximises net change velocity after coordination, operations and risk are considered. Composable is not automatically faster once integration and governance costs are counted honestly.
The right platform must manage a complete service promise, from search and purchase through change, use and support. A platform that only handles the sale is already the wrong platform for a service business.
Sound comparison requires equivalent evidence, difficult scenarios, references and a combined view of fit, cost and risk. The right vendor is the one that survives the scenario the sales demo was designed to avoid.
The RFP should make solutions, costs and risks comparable through real operational scenarios. A good RFP ends with a defensible choice the business can commit to, not a scorecard nobody trusts.
