An Agile way of reporting bugs

July 6, 2008 Indraneel 1 comment

I have seen a lot of times that when I report bugs for a product that we are building, the developers don’t really understand the problem. Some bugs are so subtle and some so complicated that it takes an essay and half a dozen annotated screenshots to cover them. And even then I get “So what’s the problem, I have no idea what you’re talking about” from developers. Reporting bugs clearly, so that the person who’s supposed to fix it understands it completely without doubts is not trivial. So I resorted to a more vivid representation – short movies with live screen-captures and voice. And suddenly the daunting task of writing an essay and seemingly endless capturing of screenshots and annotating them vanished. If you haven’t guessed it yet, I use Jing http://www.jingproject.com to do just that. Jing sits as an icon atop all windows and it takes just two clicks to start recording the screen. It produces an .swf file – occupying as less space as possible. I promptly attach it to the issue I create in the bug-tracker.
I have found remarkable success with this. The developers are happy and so am I.

Winning strategies

June 30, 2008 Indraneel 1 comment

I’ve been serving in the Agile army for sometime now. Being a foot-soldier I’ve been pretty close to ground-zero and hence to the ground realities.

Being Agile is hard. It may sound a little odd, but it is true.

Discipline

Being Agile requires quite a bit of discipline. In fact success with Agile depends on it. We were developing this shiny new product. For quite some time during one iteration our builds were failing continuously. Though we had a continuous integration platform, we lacked the discipline to make sure that builds passed everyday. Eventually when the build statistics showed us all reds for about 2 weeks continuously, we kinda woke up to it. It took us a few days to figure out what were actually wrong with the builds. Had we acted upon it the very first day the builds failed, it would have taken us a lot less time to figure out what was wrong. Moral of the story – “Having a kickass tool or platform does not mean we follow Agile methodology. The entire team has to make sure that the tools are used in the everyday life of product development. And that, requires discipline

Planning

Being Agile does not mean that we try to build an aircraft today, a wicker basket tomorrow and a flower vase the day after. Agile does not mean ‘no planning’. In fact Agile is a lot about planning.

Which bring me to iteration or sprint planning. A functionality freeze at the beginning of an iteration or sprint is not a “nice to have“. It’s a necessity for delivering a “quality” product “on time“. In one of the products that we were developing, the product manager saw the need to modify the functionality in the middle of the iteration. He had valid business reasons to do that, but that iteration was a nightmare. The quality of the product suffered badly, the developers were stressed and stretched to their extremes and the engineering manager spent sleepless nights. Unless billions are at stake, I don’t recommend doing it ever.

Design

There is no substitute for good design.
Bad Design + Flawless code = Bad product. Nobody would buy a machine which has a super fast processor but can only be started after opening the casing and finding the right wires to connect.
Excellent Design + Bad Code = Still a bad product but it’s relatively easy to fix it. Design flaws are very very expensive to fix. The chances of getting a better product increases geometrically when the design is given the enough amount of time to iterate and mature.

Teamwork

The whole team needs to have a holistic view of the product. People working in silos with blinders on don’t make a good team and are usually not at their productive best. This is a issue of epidemic proportions. I have seen it in mom-and-pop software shops as well as in Fortune 100 organizations. Good software requires more than collaboration. Each member of the team needs to understand and appreciate the big picture of the product, the purpose the product will serve and the kind of users who are likely to use the product . More often than not, engineers underestimate, misunderstand or simply ignore the value of having this holistic view. It’s not enough if only the functionality is implemented right.

Cross functional skills in the team are the need of the day. A job done by keeping in mind that one’s output will become someone else’s input is a job done well. A UI designer who knows a little about coding will be able to design the UI in a way which can make coding a breeze. An eye for detail can save a lot of time by
cutting down on rework. A developer who keeps an eye open for obvious design or UI errors can reduce rework manifolds. For example if the input boxes in a web-page are not properly aligned the developer should contact the UI developer or the designer and get it resolved before starting to code. It would take quite some rework if the non-aligned imput boxes made it to a QA build.

In the end, the success of a product depends on a lot of factors. Some of these we don’t have control over. But we gotta do our best with the factors we can control.

This is the first post in this series. There is more to come.
