Our company maneuvered themselves into a classic technical debt situation with a project of a second team of devs.

They then left, signing a maintenance contract and now barely work on the project for exorbitant amounts of money.

Of course management got the idea to hand off the project to the first team, i.e. our team, even though we are not experts in that field and not familiar with the tech stack.

So after some time they have asked for estimates on when we think we are able to implement new features for the project and whom we need to hire to do so. They estimates returned are in the magnitude of years, even with specialists and reality is currently hitting management hard.

Code is undocumented, there are several databases, several frontends and (sometimes) interfaces between these which are all heavily woven into one another. A build is impossible, because only the previous devs had a working setup on their machines, as over time packages were not updated and they just added local changes to keep going. A lot of shit does not conform to any practices, it's just, "ohh yeah, you have to go into that file and delete that line and then in that other file change that hardcoded credential". A core platform is end of life and can be broken completely by one of the many frameworks it uses. In short, all knowledge is stowed away in the head of those devs and the codebase is a technical-debt-ridden pile of garbage.

Frankly I am not even sure whom I am more mad at. Management has fucked up hard. They let people go until "they reached a critical mass" of crucial employees. Only they were at critical mass when they started making the jobs for team 2 unappealing and did not realize that - because how could they, they are not qualified to judge who is crucial.

However the dev team behaved also like shitbags. They managed the whole project for years now and they a) actively excluded other devs from their project even though it was required by management, b) left the codebase in a catastrophic state and mentioned, "well we were always stuffed with work, there was no time for maintenance and documentation".

Hey assholes. You were the managers on that project. Upper management has no qualification to understand technical debt. They kept asking for features and you kept saying yes and hastily slapped them into the codebase, instead of giving proper time estimates which account for code quality, tests, reviews and documentation.

In the end team #2 was treated badly, so I kinda get their side. But up until the management change, which is relatively recent, they had a fantastic management who absolutely had let them take the time to account for quality when delivering features - and yet the code base looks like a river of diarrhea.

Frankly, fuck those guys.

Our management and our PM remain great and the team is amazing. A couple of days a week we are now looking at this horrible mess of a codebase and try to decide of whom to hire in order to help make it any less broken. At least it seems management accepted this reality, because they now have hired personnel qualified to understand technical details and because we did a technical analysis to provide those details.

Let's see how this whole thing goes.
