I say Agile, You say Traditional, Document-Driven

Sunday, May 2nd, 2010

What do you do when your team/company is all excited to be “agile”, while your customers want to operate in the traditional, heavy-weight, documentation-driven approach? Every now and then I run into Customers or companies dealing with Customers who insists on writing pages of requirement document, with specifications as vague as the night sky, insist on accurate estimates (oxymoron) on turnaround time at the moment of document handover and to not be involved again until they receive the software they asked for?*

IMHO this is one of the biggest issues teams face when they want to use more Agile ways to deliver software. I’ve been in similar situation and sometimes have been able to influence the customers to collaborate more. Sometimes I’ve not been able to. Following tricks have worked for me in the past:

1) First and foremost, it’s worth understanding why they are opting for this approach. In most cases it turns out that they don’t trust the software team and hence they want to push all the risk to the software development side. May be they have burnt their hands in the past. May be their hands are tied. Or may be they are just ignorant of the fact that this is an extremely sub-optimal way to build software. Seeing the world from their point of view, helps me understand where they are coming from. If one is able to see the underlying driving factor and break that bubble, things can get lot more constructive. For Ex: if Risk is the underlying factor, showing them how risky their approach is, can turn things around.

2) Sometimes during the scope discussion of the project, I’m able to highlight things that they’ve not thought through. Sometimes I’m able to hit the nail where it hurts the most. Immediately, the customer moves from a stand where they were saying “We know it all, just build this” to “This piece, we are not sure and it might need a little more work, but rest of the stuff you should be able to plan & estimate”. Slowly through these discussions (couple of hours) you highlight enough such instance, to point out the fact that, there are lots of uncertainties. Also you highlight the fact that we can make assumptions and move on, but it could lead to rather adventurous ending. At this point, I pull some of the biggest project failure case studies and show them how adventurous the ending might be.

3) Sometimes, I start off saying,

I’m sorry, I’m not good enough for this job. You need an expert, who have implemented the same project many times before and is extremely desperate for work to agree to your terms of project execution or you need someone who is an expert at acting to make you feel like they are in control.

I also add saying,

It does not appear to me that your are building a software project for the first time. So if you look back at your past experience, how has this approach of building software really worked for you? Be true to yourself. Were you happy with the results? Did you feel it could have been lot faster and costed a lot less? Also did you feel the team could have come up with lot of innovative, valuable ideas in the project?

Sometimes these questions shake them up a little. At this point, they want to hear more. Its very likely that you’ve touched upon some of their fears and pain points.

4) I also bring to their attention that, I’ve worked for a lot of companies who will go with the traditional model, but put a serious (expensive) change request process. They know that on an average sized project 20-40% requirements will change as the project continues. (There are graphs that show this very clearly.) Software companies typically use this approach as a way to teach their customers a lesson. And on subsequent projects or mid-way through the project, the customer agrees to collaborate more instead of tossing it over the wall. If the customer still does not agree, heck what, you make good money through the strict change request process.

5) At this point, hopefully they are slightly more open to listening to you. So I propose that we start-off with a week or 2 week inception phase to flush out some of the uncertainties and to bring everyone on the same page, so we all can agree upon the common goals. Depending on how important this project is, we price the project inception piece of work accordingly. Sometimes even free. During the inception phase, we do some brainstorming about what we need to build, how it’s going to affect/help endusers and businesses, we build some models, we build some working prototypes, etc. This helps the customers experience the value of collaboration. (It’s like the trailer of the movie.) In my experience so far, most customers see the value, we are able to build some trust and respect for each other and we are really set to build a project using agile methods.

6) After all this, if they still don’t see the point, I tell myself,

Life is too short to waste time on such projects. Time to find a new project/customer. In fact life is too short to build products for others. Its high-time I build my own products.

Interestingly, I’ve had some customers who understand all of this stuff and tell me that the main reason they don’t want to collaborate is, they fear they might get attached to the project. And will not be able to take objective calls. This is a valid point. When I cook something, it always tastes good. Even if it does not, I keep trying to make it taste better. Hard to draw the line. In case of software projects, we can work out strategies so customers are able to collaborate but still take objective calls when they need to.

Ultra-light Development and Deployment Example

Monday, October 26th, 2009

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.
