Technological Thoughts by Jerome Kehrli

A few years ago, I worked intensively on a pet project: AirXCell (long gone ...)
What was at first some framework and tool I had to write to work on my Master Thesis dedicated to Quantitative Research in finance, became after a few months somewhat my most essential focus in life.
Initially it was really intended to be only a tool providing me with a way to have a Graphical User Interface on top of all these smart calculations I was doing in R. After my master thesis, I surprised myself to continue to work on it, improving it a little here and a little there. I kept on doing that until the moment I figured I was dedicated several hours to it every day after my day job.
Pretty soon, I figured I was really holding an interesting software and I became convinced I could make something out of it and eventually, why not, start a company.

And of course I did it all wrong.

Instead of finding out first if there was a need and a market for it, and then what should I really build to answer this need, I spent hours every day and most of my week-ends developing it further towards what I was convinced was the minimum set of feature it should hold before I actually try to meet some potential customers to tell them about it.
So I did that for more than a year and a half until I came close to burn-out and send it all to hell.

Now the project hasn't evolve for three years. The thing is that I just don't want to hear about it anymore. I burnt myself and I am just disgusted about it. Honestly it is pretty likely that at the time of reading this article, the link above is not even reachable anymore.
When I think of the amount of time I invested wasted in it, and the fact that even now, three years after, I still just don't want to hear anything about this project anymore, I feel so ashamed. Ashamed that I didn't take a leap backwards, read a few books about startup creation, and maybe, who knows, discover The Lean Startup movement before.
Even now, I still never met any potential customer, any market representative. Even worst: I'm still pretty convinced that there is a need and a market for such a tool. But I'll never know for sure.

Such stories, and even worst, stories of startups burning millions of dollars for nothing in the end, happen every day, still today.

Some years ago, Eric Ries, Steve Blank and others initiated The Lean Startup movement. The Lean Startup is a movement, an inspiration, a set of principles and practices that any entrepreneur initiating a startup would be well advised to follow.
Projecting myself into it, I think that if I had read Ries' book before, or even better Blank's book, I would maybe own my own company today, around AirXCell or another product, instead of being disgusted and honestly not considering it for the near future.
In addition to giving a pretty important set of principles when it comes to creating and running a startup, The Lean Startup also implies an extended set of Engineering practices, especially software engineering practices.

This article focuses on presenting and detailing these Software Engineering Practices from the Lean Startup Movement since, in the end, I believe they can benefit from any kind company, from initiating startup to well established companies with Software Development Activities.
By Software Engineering practices, I mean software development practices of course but not only. Engineering is also about analyzing the features to be implemented, understanding the customer need and building a successful product, not just writing code.
