People don't consider using my project. There's a client with a business problem, there's a vendor who solves problems for clients. The vendor produces an architecture document that describes how technology will achieve a solution †.
There is no noping the fuck out, as this is a hospital asking you for a one-off to manage/settle insurance payments. Or an electoral district asking you to merge three emergency response systems into one. Or Nokia asking you to tariff calls going through a switch in real time.
† This is nuanced. Often a client's procurement department invites a number of candidate vendors to submit proposals including a design proposal/architecture and associated cost estimates. Vendors range from the high end (McKinsey, Bain & Co, Ernst & Young) to the mid-tier (Wipro, Accenture and so on) to the niche.
