At the Agile Mumbai 2010, Mahesh Baxi takes you through an exciting journey of key lessons learned from one of the largest agile projects executed at ThoughtWorks which will cover:

• Key agile principles
• What challenges comes along with the scale of up to 200+ people with added complexity of distributed location
• How is it different from other agile projects in terms of planning ahead, release plans, scope management, infrastructure
• Communication – The most important ingredient for large scale agile projects to be successful
• What kind of team structure would work best?
• How to stay focused? How to identify bottlenecks and work through them

Since I’ve started working for Industrial Logic, I’ve spent a decent amount of time pair programming with folks in the US. Yes, we do Remote Pair Programming.

Quite a few people have asked me:

• What special editor or tool we use for remote pairing?
• How effective is the pairing?
• How much time is spent in setup each time?
• How long does it take for one to get used to remote pairing?

Here is my answer:

The most important part of pairing is free flow of ideas between the 2 individuals. Its about the brains of the 2 individuals being at the same wavelength so communication can truly take place. Tools can certainly disrupt or get in the way of this flow. But IMHO the individuals contribute 80% towards the success of the pairing experience, tools contribute 20%. Skype with Video Sharing lets us achieve 80%. Better tools might improve that. We’ve experimented with some Eclipse based plugins, all of them have their trade-offs. There is no clear winner. Also on our team since we’re all used to Skype for conference calls, the threshold to get started is very low. So my recommendation is to get started with simple tools, something that you are already familiar with. When starting anything new, focus on the crux and not on the peripheral stuff.

For a more introductory material on pair programming refer to Pairing FAQs.

Over the last year, I’ve been helping (part-time) Freeset build their ecommerce website. David Hussman introduced me to folks from Freeset.

Following is a list of random topics (most of them are Agile/XP practices) about this project:

• Project Inception: We started off with a couple of meetings with folks from Freeset to understand their needs. David quickly created an initial vision document with User Personas and their use cases (about 2 page long on Google Docs). Naomi and John from Freeset, quickly created some screen mock-ups in Photoshop to show user interaction. I don’t think we spent more than a week on all of this. This helped us get started.
• Technology Choice: When we started we had to decide what platform are we going to use to build the site. We had to choose between customer site using Rails v/s using CMS. I think David was leaning towards RoR. I talked to folks at Directi (Sandeep, Jinesh, Latesh, etc) and we thought instead of building a custom website from scratch, we should use a CMS. After a bit of research, we settled on CMS Made Simple, for the following reasons
  • We needed different templates for different pages on the site.
  • PHP: Easiest to set up a PHP site with MySQL on any Shared Host Service Provider
• Planning: We started off with an hour long, bi-weekly planning meetings (conf calls on Skype) on every Saturday morning (India time). We had a massively distributed team. John was in New Zealand. David and Deborah (from BestBuy) were in US. Kerry was in UK for a short while. Naomi, Kelsea and other were in Kolkatta and I was based out of Mumbai. Because of the time zone difference and because we’re all working on this part time, the whole bi-weekly planning meeting felt awkward and heavy weight. So after about 3 such meetings we abandoned it. We created a spreadsheet on Google Docs, added all the items that had high priority and started signing up for tasks. Whenever anyone updated an item on the sheet, everyone would be notified about the change.
• User Stories: We started off with User Persona and Stories, but soon we just fell back to simple tasks on a shared spreadsheet. We had quite a few user related tasks, but just one liner in the spread sheet was more than sufficient. We used this spreadsheet as a sudo-backlog. (by no means we had the rigor to try and build a proper backlog).
• Short Releases: We (were) only working on production environment. Every change made by a developer was immediately live. Only recently we created a development environment (replica of production), on which we do all our development. (I asked John from Freeset, if this change helped him, he had mixed feelings. Recently he did a large website restructuring (added some new section and moved some pages around), and he found the development environment useful for that. But for other things, when he wants to make some small changes, he finds it an over kill to make changes to dev and then sync it up with production. There are also things like news, which makes sense to do on the production server. Now he has to do in both places). So I’m thinking may be, we move back to just production environment and then create a prod on demand if we are plan to make big changes.
• Testing: Original we had plans of at least recording or scripting some Selenium tests to make sure the site is behaving the way we expected it to. This kind of took a back seat and never really became an issue. Recently we had a slight set back when we moved a whole bunch of pages around and their link from other parts of the site were broken. Other than that, so far, its just been fine.
• Evolutionary Design: Always believed in and continue to believe in “Do the Simplest, Dumbest, thing that could Possibly work“. Since we started, the project had taken interesting turns, we used quite a lot of different JavaScript libraries, hacked a bit of PHP code here and there. All of this is evolving and is working fine.
• Usability: We still have lots of usability and optimization issues on our site. Since we don’t have an expert with us and we can’t afford one, we are doing the best we can with what we have on hand. We are hoping we’ll find a volunteer some day soon to help us on this front.
• Versioning: We explored various options for versioning, but as of today we don’t have any repository under which we version our site (content and code). This is a drawback of using an online CMS. Having said that so far (been over a year), we did not really find the need for versioning. As of now we have 4 people working on this site and it just seems to work fine. Reminds me of YAGNI. (May be in future when we have more collaborators, we might need this).
• Continuous Integration: With out Versioning and Testing, CI is out of question.
• Automated Deployment: Until recently we only had one server (production) so there was no need for deployment. Since now we have a dev and a prod environment, Devdas and I quickly hacked a simple shell scrip (with mysqldump & rsync) that does automated deployment. It can’t get simpler than this.
• Hosting: We talked about hosting the site on its own slice v/s using an existing shared host account. We could always move the site to another location when our existing, cheap hosting option will not suit our needs. So as of today, I’m hosting the site under one of my shared host account.
• Rich Media Content: We questioned serving & hosting rich media content like videos from our site or using YouTube to host them. We went with YouTube for the following reasons
  • We wanted to redirect any possible traffic to other sites which are more tuned to catering high bandwidth content
  • We wanted to use YouTube’s existing customer base to attract traffic to our site
  • Since we knew we’ll be moving to another hosting service, we did not want to keep all those videos on the server which then will have to be moved to the new server
• Customer Feedback: So far we have received great feedback from users of this site. We’ve also seen a huge growth in traffic to our site. Currently hovering around 1500 hits per day. Other than getting feedback from users. We also look at Google Analytics to see how users are responding to changes we’ve made and so on.
• We don’t really have/need a System Metaphor and we are not paying as much attention to refactoring. We have some light conventions but we don’t really have any coding standards. Nor do we have the luxury to pair program.
• Distributed/Virtual Team: Since all of us are distributed and traveling, we don’t really have the concept of site. Forget on-site customer or product owner.
• Since all of this is voluntary work, Sustainable pace takes a very different meaning. Sometimes what we do is not sustainable, but that’s the need of the hour. However all of us really like and want to work on this project. We have a sense of ownership. (collective ownership)
• We’ve never really sat down and done a retrospective. May be once in a while we ask a couple of questions regarding how something were going.

Overall, I’ve been extremely happy with the choices we’ve made. I’m not suggesting every project should be run this way. I’m trying to highlight an example of what being agile really means.
