There's a question I get asked a lot, dressed up in different ways: "tell me about a transformation you led." Most people expect a story about a system replaced, or a process made faster. The story I actually want to tell is a different shape. The best transformation I ever ran ended with the business not needing me for that piece of work anymore.
At Apple, working on iPod, part of my job was to get the finance process wrapped around the product line into better shape, cleaner reporting, a faster forecast cycle, less manual reconciling between the local teams and EMEIA team. I reengineered it to the point where the role I'd been doing wasn't needed anymore. That's an odd thing to put on a CV, because it can look like you designed yourself out of a job. It's the opposite. More got done, with fewer resources, because the process did the work that used to depend on a person pushing it through by hand.
That's not a failure. It's the point.
Most transformation projects get judged at go-live. Go live, tick the box, move on to the next initiative. The real test comes six or twelve months later: does the thing still run properly without the person who built it standing next to it? A lot of "successful" transformations quietly fail that test. The system's still there, but someone still has to work around it, patch it, explain it to whoever's new.
At ARM, I built and led an FBP team across a complex, multi-geography business, and the piece I'm proudest of isn't a single project. It's the planning tools and the data quality work that outlasts my time there. Better underlying data, less manual work. That's not just an efficiency gain, it's a decision-making game changer because it frees the team to spend their time on the analysis that actually shapes decisions rather than fighting the numbers into shape every month. The team didn't just inherit a better system. They inherited the skills and the confidence to keep improving it without me.
This matters for how businesses should think about bringing in senior finance help, not just how they manage it day to day. If you're hiring a fractional FD or a finance leader for a transformation piece, the question worth asking isn't "will they get it live." It's "what happens to my team's capability after they leave." Someone who builds their own indispensability into the process has quietly made themselves a permanent cost. Someone who builds capability into the team has done the opposite. They've made the business stronger, and made their own role, for that piece of work, optional.
The practical version of this is fairly simple, even if it takes discipline to hold to. Document the reasoning behind decisions, not just the decisions themselves. Coach the team through the "why" while you're still there to be challenged on it, rather than leaving a manual behind and hoping it sticks. And treat a successor being ready to take over as the success metric, not as a threat to how useful you look.
That's the part of finance transformation I care about most: not being the person a team relies on, but building the team and the process so they don't have to. If you're wrestling with this in your own team, I'd enjoy comparing notes.
