How the work is organised
Three habits that show up in every engagement.
Start at the decision
Every build works backwards from the decision someone has to make, not forwards from the data that happens to exist.
Design for the non specialist
If a platform only rewards a trained analyst, it has quietly excluded most of the people it was meant to serve.
Leave capability behind
Training, documentation and internal ownership are part of the delivery, not an optional extra at the end.
Answering the public's curiosity
Short answers to what people search for most often.
