I am based in the UK. I work as a software/automation engineer in department A. Recently, department B bought software from a big-name company which uses yaml files to steer/control automation framework (think IaC). I don't work for/with anyone in dep. B, but they showcased their new software to few different departments (including mine) - hence I learnt about that software. Now, during presentation, it came up that while controlling everything through YAML files is amazing (thanks to git versioning, webhooks etc.) it was brought up that manging 100s of files and lines of code will be difficult due to amount of places to change single value. When discussed, it was stated that there is no plans to create any frontend by that company to manage all those files and this seemed to upset a lot of stakeholders. The software has been purchased and it's going to be rolled out anyway.

I see this as an opportunity to step in and sell the idea of creating frontend for this tool, however I don't want to do anything for free. Since I don't work in this department directly, I don't know how I should approach this. Perhpas I should create MVP first and engage with some stakeholders and see if they are interested?
