Speaker A

So, um, when we started the— the project, we didn't really, you know, we didn't really understand the full scope of, of what we were getting into? [laughs]

Speaker B

Yeah, no, absolutely. I mean, it was— it was like, uh, we had this— this idea that it would take maybe, like, six months? But then, um, [clears throat] but then reality hit and we realized it was gonna be more like, like two years.

Speaker A

Mm-hmm. And the— and the funding was, was a whole other story. We had to— we had to go back to the, uh, to the board and basically say, “Look, we need— we need more time and more resources.” [pause] Which, you know, was not an easy conversation.
