A successful spreadsheet vision job is not a pile of tools. It is a sequence: a good image, good fixturing, good tools, good math, good I/O, and a good HMI.

Six boxes show Image, Fixturing, Tools, Math, I/O, and HMI. A forward arrow denotes construction; a reverse arrow denotes tracing the reported result back to its source.
D01. Build from image formation toward the human interface. When a reported failure needs explanation, trace the result back toward its inputs. The reverse path is a diagnostic method, not a requirement to ignore an obvious image defect.

Wizard-style builders are useful for simple jobs and awkward for complex ones, but their order is still the right mental model. Image formation comes first because every later tool inherits contrast, focus, and part presentation. Fixturing then locks a stable reference so measurement and reading regions move with the part. Tools extract features. Math turns those features into pass, fail, and messages. I/O delivers a handshake the machine can trust. The HMI explains the result to a person who was not in the room when the job was written. Skipping a milestone does not save time. It moves the failure downstream, where it is harder to see.
