One inspiration for gradual enrichment is spreadsheets. In a spreadsheet, a user can start writing down data in a freeform grid, without committing to any particular structure. They can then write formulas that run computations on information, if and when it’s useful to do so. Eventually, after lots of iterations, they might arrive at a highly complex software application, but one grown organically from their data and unique needs. At every point along the way, the artifact remained useful and grounded in real needs.
