Like the classic, inherit a broken code base, and not being allowed by the owner to rewrite it from scratch. So you have to spend more time making each part work without the others working. Also before you are finished the customer says they have something else for you to do
Programmers love to rewrite things, but it’s often not a good idea, let alone good for a business. Old code can be ugly because it is covered with horrible leasons and compromises. A rewrite can be the right thing, but it’s not to be taken lightly. It needs to be budgeted for, signed off on and carefully planned. The old system needs to stable enough to continue until the new system can replace it.
That’s when you start introducing modules that have the least impact on the legacy code base. Messaging is a good place to start, but building a new code next to the existing one and slowly refactoring whenever you got time to spare is at least a bearable way to go about it.
