In an ideal world, a finished piece of software, designed as per the specification, should equate to neat Jenga bricks, all stacked in 3 x 3 perpendicular rows.
So think back to our Jenga tower, delete one block of ‘Jenga code’, just one word, one value or one command and it could be the same as removing one block too many from the tower. Crash.
A logic path contained an error that was uncovered in our last sprint. The developer fixing the problem fixed the error, but didn’t touch the rest of the method – a Jenga player touches one brick at a time.
