What do hitting a golf ball and software development have in common?

Well I'll tell you...consistency and quality.

Tad-da...I present to you, AGA..Agile Golf Analogy...that's right folks, you heard it here first. The next time you hear "We've just duffed the project into the rough" or "We're in a bunker with the workflow components" you know there it originated.

I've have a couple of conversations over the last few days about our experiences using SCRUM and as usual there was lots of interesting thoughts and theories to emerge. It wasn't until I was at a driving range with some other guys from work and one of them said "it's the same swing just a different club" that it hit me. The key to a great golf swing is absolute consistency in the rhythm, effort, control and technique you use. The golf club does the hard work for you.

  • Your shot is your Sprint.
  • Your swing is your project team.
  • Your club is your engineering practices.
  • Your ball is your softwares functionality.
  • The pin is the Sprint Backlog.
The objective is to get the ball from the tee to the target...easy right?

Want to hit the ball further? Use a bigger club.

DO NOT try to hit the ball harder with the same club.

Want to produce more software during a sprint? Use better engineering practices.

DO NOT push your team harder and make them work longer hours.

Want to hit the target? Make sure you are lined up with it.

DO NOT start implementation without knowing enough about what you are trying to build. [I'm not advocating complete upfront analysis, no sir! Just shifting it prior to Sprint start to gain a little more knowledge and increase utilisation consistency.]

It was about this point at the driving range my game took a complete nosedive!! BTW I can highly recommend the

TopGolf

computerised driving range we were at. It's like a cross between a bowling alley and a driving range. You have RFID enabled balls and lots of target holes - the nearer the hole the more points you score - there are lots of types of games you can play...I liked the "Snooker" variant - need to get a red (easy hole) followed by a colour (harder). If you are a seasoned golfer this really does highlight any problems with your accuracy!

Oh yes, were was I?

To focus on the consistency more I'd like to share our thoughts. We started a Sprint and our analyst and business domain experts got together to discuss the Sprint backlog. Meanwhile the developers, although not idle were largely waiting on some sort of output so we could start coding. Once we understood what we were building we got on with it and the analysts wound down with occasional bursts of clarification activity. The top left graph shows (exaggerated) a view on how this looked workload wise.

Sprint characteristics


Problem: Starting analysis at the beginning of the Sprint

Results:

  • Inconsistent utilisation across the team.
  • Delayed start to implementation whilst waiting for analysis to complete.
  • Inadequate analysis as pressure is on the get the development team productive.
  • Descoping of Sprint backlog items as the team is over committed because of a lack of knowledge about the actual requirements complexity.

The bottom left graph shows how this effects the Sprint - the team has insufficient understanding of the business functionality and based on their current (mis)understanding of the requirement they take onboard more work that they can complete. It is not until they are well into the Sprint and their understanding has increased do they realise the requirements are actually much more complex then envisaged and that they have overcommitted themselves.

Resolution: Shift the start of Sprint backlog selection and analysis into the previous Sprint.

  • The analysts have time to understand a better (not full) picture of the requirements complexity.
  • More time spent on analysis leads to a more granular, less monolithic understanding of each requirement. Is may be possible to acheive some of the functionality rather then dumping the whole requirement.
  • The team have more knowledge and can make a better guestimate of what they can actually acheive in the Sprint.
  • A clearer picture emerges earlier in the Sprint of what will be built - no awkward "Sorry, but we've had to descope that, and that...oh, yeh that went too" conversations a week before Sprint end. The product backlog also has a truer reflection on the state of play.
  • Team moral remains high, no feelings of inadequate performance as they cannot complete what they had originally stated they will deliver.

So ends part one of AGA...I'll flesh this out more on the engineering practices side of things very soon as I'm dying to get hooks, slices and especially shanking into this somehow!

Do this stuff actually work?

Exactly the solution we came up with, too. Otherwise the Sprints are unbearably stressful. Perhaps with a pure XP team (no designated "analysts") this is different, or perhaps they sacrifice someone in each sprint to prepare for the next?

(and, in answer to the previous comment: yes, absolutely, this stuff works! Check out controlchaos.com !)

Walk-Thru: Using Wolfpack to automatically deploy and smoke test your system

First, some history... The advent of NuGet has revolutionised many many aspects of the .Net ecosystem; MyGet, Chocolatey & OctopusDeploy to name a few solutions building upon its success bring even more features to the table. I also spotted that NuGet could solve a problem I was having with my OSS System Monitoring software Wolfpack ; essentially this is a core application framework that uses plugins for extension ( Wolfpack Contrib ) but how to unify, standardise and streamline how these plugins are made available? NuGet to the rescue again - I wrapped the NuGet infrastructure (I deem NuGet to be so ubiquitous and stable that is has transcended into the software "infrastrucuture" hall of fame) with a new OSS project called Sidewinder . Sidewinder allows me to wrap all my little extension and plugins in NuGet packages and deploy them directly from the Wolfpack application - it even allows me to issue a new version of Wolfpack and have Wolfpack update itself, sweet huh

Configuration in .Net 2.0

11-Dec-2007 Update I've updated this post to fix the broken images and replaced them with inline text for the example xml and accompanying C# code. This post has been by far the most hit on this blog and along with the comments about the missing images I thought it was time to update it! Whilst recreating the examples below I zipped up the working source code and xml file and loaded this onto my Project Distributor site - please download it to get a full working custom configuration to play with! Just click on the CustomConfigExampleSource link on the right hand side, then the "Source" link to get the zip. We are in the process of converting our codebase to .Net 2.0. We've used Enterprise Library to great effect so decided that we should continue with this in the form of the Jan 2006 release which targets 2.0 and I've got the job of porting our Logging, Data Access etc wrappers to EntLib 2.0. ...And so far so good - the EntLib docs aren't bad and the migrati

Castle/Windsor schema enables Visual Studio intellisense

There has been a lot of noise recently about Inversion of Control (IoC) with .Net recently (stop sniggering at the back java guys!).... I've been using IoC via the Spring.NET framework for over 2 years now - it's a completely different approach to coding and once you get your head around it everything just falls into place and development is a real joy again. As I mention, Spring.NET is my framework of choice but a recent change in employer has seen me bump up against Castle/Windsor . First impressions are that I like it - it's not as powerful or feature rich as Spring but that's not always a bad thing! The one thing I did miss though was Visual Studio intellisense when editing the configurations - Spring has an online schema that can be associated with a Spring configuration. This got me thinking - if the VS intellisense can be hooked into that easily why not create one for Windsor configuration? So I did...you can download it from my new google code site here . Remem
