Last year, when we were helping to develop YourNextMP, the candidate-crowdsourcing platform for the General Election, we made what seemed like an obvious decision.
We decided to use PopIt as the site’s datastore — the place from which it could draw information about representatives: their names, positions, et cetera. We’d been developing PopIt as a solution for parliamentary monitoring sites, but we reckoned it would also be a good fit for YourNextMP.
That turned out to be the wrong choice.
YourNextMP was up and running in time for the election, but at the cost of many hours of intensive development as we tried to make PopIt do what was needed for the site.
Once you’ve got an established site in production, changing the database it uses isn’t something you do lightly. But on returning to the codebase to develop it for international reuse, we had to admit that, in the words of mySociety developer Mark Longair, PopIt was “actually causing more problems than it was solving”. It was time to unpick the code and take a different approach.
Mark explains just what it took to decide to change course in this way, over on his own blog.
The post contains quite a bit of technical detail, but it’s also an interesting read for anyone who’s interested in when, and why, it’s sometimes best to question the decisions you’ve made.
