He advises that those thinking of a portfolio career should start with the ideal whole portfolio in mind, considering aspects like flexibility. “Don’t start by looking for a non-exec role: start by working out what having a portfolio means for you and your whole life plan,” he adds. “How busy do you want to be? What else do you want to be doing? How flexible do you want to be? Non-executive work is not flexible: the board meetings are in the diary for the next two years and can’t be changed. Do you want what comes with chairing committees?”

Alongside that, aim for clarity on what you hope to gain from a NED role, whether that is working as part of a team, learning a new sector or enjoying transformation. Once you know what a good role would look like and why you want it, let executive search firms know – so you are on their radar for suitable openings. You will need to position yourself differently. “Exec jobs are about positioning yourself based on what you can do; non-exec roles are about positioning yourself around what questions you can ask and what you can bring to the board discussion,” says Simon.

When joining a board, active listening and keen observational skills come to the fore. “Understand the context and then work out where you can bring something valuable to the discussion and conversation,” he advises. “You need to challenge, bring balance and different perspectives. It’s more like having a coaching conversation than being the leader.”

You’ll also need to be prepared for the volume of pre-work required for each meeting, which can run into hundreds of pages, and the need to be across all of it. As for the best advice Simon has ever received around being a NED? “Non-execs should be hands out, noses in.”

Simon’s top tips

• Think about what the ideal portfolio looks like for you. How flexible do you want to be?
• Expand your network of executive search firms and influencers.
• Position yourself differently: NED roles are more about ‘asking’ than ‘action’.
