System active
You should not need another workaround.
The most useful software projects often begin with an ordinary operational frustration.
- 01Your team copies the same information between systems.
- 02A critical process lives in a spreadsheet and someone’s memory.
- 03Emails and documents consume hours of repetitive attention.
- 04A good product idea needs a credible first version.
- 05Two essential systems refuse to talk to each other.
- 06An existing website or application has become a liability.
