My book, Designing Data-Intensive Applications, was published by O’Reilly in March 2017.
Published by Martin Kleppmann on 31 Dec 2009.
It’s the end of the year, a good time to take a step back and reflect on the past year and what it means for the future. For me, 2009 has been dominated by building Go Test It and then selling it to Red Gate. That’s a pretty successful year in my book.
Over Christmas I finally had time to read The Four Steps to the Epiphany by Steve Blank. I had heard from a few people that it was the best book in the world for startups, but of course you take that sort of recommendation with a grain of salt. When I finally got round to ordering it, my first impression was not very impressed. The graphics are misaligned, the typography is ugly, there are plenty of typos, the cover picture is cheesy, the CafePress binding is flimsy. All in all, not a good start.
Well, don’t judge this book by its cover. Despite those apparent flaws, it is absolutely brilliant. And yes, if you have any sort of startup ambitions, you should go out and read it immediately.
In fact, maybe the book is deliberately ‘unprofessional’, because that would be consistent with a theme which runs through the entire book: focus relentlessly on what really matters and what really adds value. What really matters to me with Steve Blank’s book is purely its content (which is clearly articulated and deeply insightful); professional design or editing wouldn’t have changed this book’s value to me. Similarly, what really matters with a startup is to discover and learn what customers need, how the product fits into their lives, and how you are going to get it into their hands. ‘Professionally’ executing a strategy comes later. First you’ve got to learn and discover what the strategy is going to be.
This sounds trivially obvious, but it is not.
Let me digress for a minute. Something else I read recently is The Fable of the User-Centred Designer by David Travis (a short but beautifully written eBook – well worth reading but quite different from the Four Steps to the Epiphany). It made me realise how badly we had gone wrong with Go Test It. Steve Blank’s book further strengthened that feeling. Ok, we built a product which works alright. We did a few informal usability tests (looking over people’s shoulder while they use it for the first time) and we got some useful feedback from the beta tests. And clearly the result was promising enough that Red Gate wanted to acquire it.
Here is my confession: I cannot truthfully say that we really engaged customers in the process. I had some ideas about use cases and I did a few pencil sketches of the user interface before it was implemented. But did I actually go out to potential customers and test my ideas on them? Not a single bit! We thought about the ideas for a few minutes by ourselves, nodded our heads, and then just went ahead and hacked it together.
I have no excuse whatsoever for ignoring our customers like I did. Hell, we even had a poster from the Usability Professionals’ Association hanging in our office for a while, detailing the steps of a user-centred design process. (Some years ago I thought our company was going to be a usability consultancy – that was before we got into web development and ultimately into building Go Test It. Hahaha! By the way, that’s why this blog is called Yes/No/Cancel.) And nevertheless I totally ignored it. We were not doing anything like user-centred design, let alone Customer Development as proposed by Steve Blank, which is a lot further-reaching.
So: building something which scratches your own itch is better than building something which you don’t even need yourself. But it’s still a pretty bad starting point, because you are only one data point. How do you know that you’re not an outlier? In our case, I was even a pretty bad data point. I had only worked on two significant commercial web app projects – not exactly a great deal of experience. I had never worked in a proper web agency, or a larger software company, or an established e-commerce retailer, or in fact any company which looked remotely like the type of company we’re trying to sign up as customers.
What we should have done – and I understand this now – is to follow a Customer Development route from the start, alongside building our product. Before the coding started, I should have at least made my hypotheses explicit, tested them on my target market, and refined the product idea. Basically, I should have read The Four Steps to the Epiphany a year ago and then followed it.
In my defence, it’s difficult when you are a sole founder. In principle you could multitask between Customer Development and Product Development, but I think the two activities require very different mindsets, and the context switching overhead between the activities is huge. Therefore I suspect that a sole founder doing both will take much more than twice as long compared to two cofounders who specialise in Customer Development and Product Development respectively. Hence it’s extremely tempting for a technical founder like me to pretend that the Customer Development side doesn’t exist, and focus exclusively on the product.
Well, late insight is better than never. Amir is joining me on the Customer Development side of Go Test It, and we have a lot of catching-up to do. In 2010 there will be soul-searching and maybe some changes of plans, but I am really looking forward to it, because I am confident that we can figure out how to turn Go Test It from something ok into a product which you simply must have.
