A business solution is not simply a piece of software or a contracted service. It is an operating arrangement that defines what information is authoritative, who may act, how work advances, and what happens when the normal path breaks. The product matters, but so do the process and ownership decisions around it.
Understanding that arrangement makes comparisons more useful. Instead of asking whether a platform has many features, readers can trace how a requirement becomes a record, how that record changes state, where handoffs occur, which controls apply, and how the organization learns whether the process is working.
