What does a really effective multi-disciplinary team look like? Well, it probably looks a lot like The Beatles. They released 12 albums and over 200 songs in 8 years. And in those 8 years they evolved more than most artists do in a lifetime.

I believe that product development is more art than science. It is messy, collaborative, experimental, unpredictable, and fundamentally creative.

Peter Jackson’s new documentary Get Back gives us an incredible insight into The Beatles’ creative process and mindset. Here are four lessons I took from watching the series.

Lesson #1 — Move fast and release things

The Beatles work quickly, and like to finish stuff. When George Harrison is struggling with a new song he quotes the advice John Lennon gave him many years earlier: “Finish them straight away, as soon as you start them.”

They talk a lot about the value of pressure, deadlines, and having their “backs to the walls”. It’s striking how hard and fast they want to work. As Paul McCartney says: “Achieve something every day.”

We see this in full with the development of the song Get Back. On the 7th January, McCartney creates the song from nothing. As he jams and experiments on his bass guitar, the melody appears and other band members begin to join in. Two weeks later the track is fully formed, and they get the idea to “just put it out as a single next week”, “like in the old hustling days”.

As they talk there’s a great line from producer Denis O’Dell who sums up the attitude: “Never save a good idea, do it.”

The Beatles always recorded fast — that’s how they made all those albums. They liked to get stuff finished while it was fresh. They talk a few times about the risks of over-thinking and over-playing tracks to the point that they go stale. Release early, release often. Stop starting and start finishing. The Beatles had these nailed.

Lesson #2 — Embrace creativity

It is fascinating and great fun to watch the band experiment, jam and practice. They show a surprising mix of seriousness, ambition, and playfulness. As they work on songs they go off on tangents, do lots of ‘silly’ takes, and add and reject ideas continuously. Their studio is a place where the brainstorming cliché is actually true: there’s no such thing as a bad idea.

When they are struggling with a track McCartney says they should “play it shitty ten times so it’s in there, and then I think we can play it quite good.” Lennon often wants to “improvise it”, and Harrison wishes they would just rehearse and “carry on until it gets better.” Later he puts it beautifully: “Whatever it’s going to be, it becomes.”

In the world of digital and technology I often feel like we underestimate the need for creativity and collaborative experimentation. We tend to focus on theory, rationality, frameworks, inputs and outputs, ceremonies, and a belief that the right process will deliver success. We have created cultures where having an idea is criticised as jumping to a solution.

Watching The Beatles at work shows what it feels like to be on a team that is really flowing. The magic is in the collaboration, the space to breathe, the batting around and testing of ideas, the ‘strong opinions, loosely held’, and enjoying the journey while having high expectations and a real focus on quality.

Lesson #3 — Nothing is new

The Beatles were extremely creative and original. But at the same time, lots of their music was simple, generic, and derivative. In the studio they mix and match constantly, blending their new songs into their old songs into other people’s songs. George Harrison arrives one day with a new song, I Me Mine, inspired by a waltz he saw on TV the night before.

In a wonderful exchange, Harrison says their new track, Don’t Let Me Down, “sounds like the same old shit.” Lennon’s response: “Well I like the same old shit, if it is clear.”

The documentary brings home the truth that there is no such thing as a completely new idea. We are all building on what’s gone before. Maybe this is summed up best when Paul McCartney looks down at the piano and says, “the great thing about a piano is like, there it all is. There’s all the music that’s ever been written.”

Lesson #4 — This stuff is hard

Get Back provides a complete (8-hour long!) picture of the creative process. Even while we’re watching a great band, often joyful and completely at ease, doing brilliant work; those moments are countered by the struggle. They get bored and tired. They lose confidence. They grumble and bicker. They hold back tears. They overthink things, and go down dead ends.

“I think it is awful actually” says Harrison of one song. “I can’t think how to do this one at all,” says McCartney, looking a bit broken.

But they push on, powered by their work ethic and a sense of purpose. At one of their lowest moments, Lennon says, “I’ve decided the whole point of it is communication. We’ve got a chance to smile at people.” For McCartney it is simple. “I’m here because I want to do a show. We either go home, or we do it.”

It is great to see and appreciate that even with all that talent, and all those resources, this stuff is never easy.
