Where they differed most
A 25-person charity asks you to automate its expense approval: every claim, whatever the amount, currently needs a line manager's signature, then the finance officer's, then a trustee's, and a claim for a £14 train fare took nine days last month. They want a workflow tool that routes it through all three faster. Give them the honest answer. Explain why automating this process as described would make the wrong thing efficient, what question they should be answering instead, and what the design would look like if the goal were 'the £14 fare is paid this week and the trustees still see what they need to see'. Be concrete about what you would keep — say what a trustee genuinely needs oversight of and how they would still get it.
Here is the honest answer you need to give them. ### Why automating this process makes the wrong thing efficient Automating a nine-day, three-signature process for a £14 train fare doesn’t fix the problem; it just digitizes the bureaucracy. In software design, this is called "paving a cow path." You are taking a broken, over-engineered workflow and making it run slightly faster, but you are still wasting three people’s time on a £14 claim. The bottleneck isn't the medium (paper vs. software); it’s the rules. By demanding a trustee’s signatur…
**Don’t buy a workflow tool to rush every claim through three signatures.** That would make the wrong thing efficient. ### Why “route all three, but faster” is the wrong move You would be automating a control design that treats a £14 train fare like a material commitment. The delay is not mainly a software problem; it is a **proportionality** problem. - Three human approvals on every amount signals that *no one is trusted with small sums* and that *trustees are a routine processing step*, not governance. - The hidden cost of nine days and thr…
