ENDCAP — YOUR ONE-TASK PROJECT BRIEF Who will use this? What is one task they need to finish? What goes in, and what should come out? What could go wrong? How will we know it works? Who looks after it? Compare: improve the spreadsheet / buy software / connect existing tools / build a focused tool. Include setup, moving data, training, subscriptions or hosting, support, ownership, and export. endcap.design/learn/spreadsheet-software-or-custom-tool/
