Lessons Learned by Eric Ries Monday, March 16, 2009 Combining agile development with customer development Today I read an excellent blog post that I just had to share. In most agile development systems, there is a notion of the "product backlog" a prioritized list of what software is most valuable to be developed next.

Focus on the output metrics of that part of the product, and you make the problem a lot more clear. I had the opportunity to pioneer this approach to funnel analysis at IMVU, where it became a core part of our customer development process.

The design failure meant that there was constant thrashing as the servers struggled to provision capacity according to the “elegant&# algorithm we’d designed. Are the engineers in the customer development team allowed to push quick and dirty "prototypes" to production? One last thought. Eric, great post.

For the past couple of years Ive used a question that I once was asked in an interview, in which you have the candidate produce an algorithm for drawing a circle on a pixel grid. As they optimize their solution, they eventually wind up deriving Bresenhams circle algorithm. Case Study: Continuous deployment makes releases n.

Because five whys kept turning up a few key metrics that were hard to set static thresholds for, we even had a dynamic prediction algorithm that would make forecasts based on past data, and fire alerts if the metric ever went out of its normal bounds.

At least, not in the traditional sense of trying to squeeze every tenth of a point out of a conversion metric or landing page. Instead, we try to accelerate with respect to validated learning about customers. Even if it shows improvement in some micro metric, does that invalidate the overall design? No one feature is to blame.

More common is to use a one-way hashing algorithm to map the data to be accessed to one of the shards that store it. Theres no complex algorithm to go wrong, just a simple lookup table. Of course, you could use URL-based sharding to "wrap" a CH algorithm (or any hashing scheme you wanted).
