WOW! I just realised that it’s been a year since I did a blog post. I knew it had been a while, but I figured around 6 months max… Well, I suppose I needed it, and the good news is that I’M BACK!
I’m not going to go in to what has transpired over the past year since an agile adoption, as it’s quite involved and will come out in some successive posts, but will focus on where I am now and what my Posting Plans are.
Near the end of last year we started planning a return to Australia after almost a decade in the UK – what a BLAST! So many lovely experiences, people, places and new friends :-) Eventually though, it was time to return to Australia as it really is my home and although I may have a few gripes about it, Australia really is an amazing place and as the old cliche goes: I now really appreciate how lucky I am to live in this country after being away so long. That shot above is from my local beach which is 3 mins drive, and I can get in to the city (in the distance) in around 1/2h with a walk and public transport – that’s a pretty good lifestyle.
So what’s in the pipe? A much more varied mix than when I started out doing just “software stuff”:
- Reflections on life in the UK and Europe
- Observations on life in Australia now I’m back
- Reviews of gadgets
- Travelogues as I explore my own country – now I’ve probably seen more of Europe than I have of Australia, so it’s time to correct that
- Process – yes, I’m still on the agile path
- Architecture – looks like that will be my primary area of work still
- Software – which I’m gradually getting back in to, with the current focus being Clojure
- Probably the odd bit of music or photography to round things out
- Anything else anyone would like me to write about…
It’s been quite a while since I’ve posted much, mainly due to a contract which requires me to drive on the M20 and M25 (aka “the carpark” for those outside the UK) and as a result, I just don’t seem to of had the time and energy…
I look forward to getting on something where someone else is doing the driving so I can use my time effectively
Amazingly, it seems like only 7% (4.5 Million) people in the UK use public transport. Given that nearly 1/3 (22 Million) live in the South-East, where transport is generally pretty good, that seems pretty low. No surprise given the number of people on the motorways – I’ll be happy to take one more off them next contract.
So what’s up for 2015 for me and this blog?
For one, I plan to start getting back in to a bit more of a rhythm, both with my posts and the associated (play) work (generally outside “real work”), and I will continue to post based on my experiences – recent and past…
- Lifestyle & Reviews
- Process & People & ScramJet
- Architecture, including Enterprise & SOA aspects
in no particular order. I won’t get in to specifics as much of it is not yet planned, or I’m working on it but don’t want to reveal it until I have enough meat on the the bones so I can be sure it will fly.
- Review of Bob Marshall’s “Thinking Different” happening last year
- Review of the: BMW i3 electric car; Samsung Galaxy Alpha
- Corporate Subversion – in a positive manner of course :-)
and that’s really just the “boring stuff” – there should be some very interesting posts coming as I hit my stride.
I hope you’ve all had a great XMas & New Year break and look forward to some great interactions in 2015!
Today I’m (@RiczWest) starting a new twitter account. It’s called ChangeArc. For those who follow me, you’ll recognise this as my “Blog Name” – so what’s the purpose?
Simple – when I started using Twitter, it was primarily as a bookmarking tool. To some extent I still use it as such, but also for so much more…
There’s one problem though – as I look at a lot of content, that means a lot of tweets, and not everyone likes that, including me! There are a number of great people I’d like to follow, but I can’t because they tweet too much.
To that end, I’m going to start a much lower volume (only a few tweets per day) account which is ChangeArc. So what can you expect apart from less tweets? Extremely high quality tweets that will include any posts I do.
I don’t know how this will evolve, but it will be interesting to see…
It’s amazing how time flies as it seemed like yesterday, but it’s now been 8 years. Must be that old adage as I’ve certainly been having a lot of fun here. When I’d finished my last post on this, Agile Baby Steps – Iteration 3 (2 & 1), I’d finished up in Australia and moved to the UK. By coincidence it was where my Agile journey got a bit of a Turbo-Boost
After a few months of being a tourist and “kinda looking for work” I finally ended up in Andover which is a nice “little” market town just over an hour out from London working with Lloyds TSB. The role was initially as a Service Designer, but due to some enlightened management there I was able to introduce Scrum. Remember that in Aus I’d only just used it with a Scrum Master to integrate with Rational Unified Process, so I’d only just started down this route. To do a proper implementation we ran training with about 15 people and a Scrum Alliance trainer. This was the first time I’d been exposed to “pure Scrum” and it absolutely blew my mind! During the time there we rolled Scrum out across the various projects in the Business Process Re-engineering programme, even scaling it. Probably the key reason things went so smoothly was that the programme was Agile in it’s BPR activities and there had been a Lean effort in the past. Also, the programme had the concept of “Daily Prayers” that were like a Scrum, only unstructured so Scrum was really just a refinement (as the DP’s weren’t scaling) and extension which made sense as the program was just starting.
Next along was TNT and I had no intent originally for any process work as I was just there to do some performance tuning and architectural refactoring. After a few weeks though, it emerged that the team they were building up was having problems keeping track of things. One of the lessons I learnt from the previous engagement was not to be too prescriptive, so I said I knew a simple technique that could help. I told them the basic rules of Scrum and had Backlog, Doing, Done but did not tell them what to put on the stick notes! In the beginning it was just the task but after the first retrospective someone suggested adding the person responsible – “great idea” I said ;-) After the next retrospective, they suggested adding time! They’d invented Scrum Sticky Notes! I think this is a great example of what happens when you trust people and let them own “the process solution”.
Even better, was the fact that this was integrated with their existing Project Management process as at the end of each sprint I gathered up all the sticky notes and gave them to my enlightened PM who then did whatever she did with Gantt charts, reports etc… As the Scrum Master, I worked hand-in-hand with my PM and it only took less than 1h per day for me as the PM handled all the issues. Oh, but it didn’t stop there – we had an offshore team also. Again, thanks to enlightened management, we had a number of devs from offshore being rotated in and the timing was perfect. After a few weeks some of them went back to India and because they knew the process (it was theirs after all) Scrums were quickly up and running over there. We’d then have a teleconference Scrum to sync everyone up which worked a treat.
The interesting thing about the TNT implementation was that the “pure Scrum” people would be frothing at the mouth as we’d probably broken a number of “rules” – e.g. estimating in time, rather than story points, bananas, etc… Yet, I’d regard this as on of my best Scrum implementation so far as we’d cracked two of the classic problems that people have:
- Working in a more conventional Project Management process and
- Working with offshore teams
Most of this was not to do with me, it was obviously the management chain running through 3 levels who all supported this as what they’d been doing obviously didn’t work as well – they were ripe for change.
After a “pure SOA Architect” role I then ended up in Agile Land, this time at Yell (RIP ;) which was an Agile environment – and I really mean this! They were running a whole BPR programme using Agile with some of the best coaches I’d worked with. Needless to say, I learnt a lot about the subtleties of Agile and was even able to contribute at the end in helping develop a more scaled version of agile based around Dean Leffingwell’s Scaling Software Agility for the entire enterprise. One of the key lessons though was that you can be “too agile” – at one stage, as an Agile SOA Architect, I was continually (every few weeks) altering service designs for the Implementation teams. In the end, they (nicely) screamed “Enough! We can’t absorb this much change!”. As a result of a retrospective workshop we did on this issue, it was agreed that there should be a bit more up-front work and broader investigation in order to minimise the change to the designs they were implementing.
Coming off the pure agile role, I landed in what was at one stage one of the largest Agile projects in Europe at British Gas. Due to it’s scale (we’re talking thousands of people) there were some waterfall elements to it, but the base rule was that wherever Agile made sense, we’d use it. Again, more amazing scum masters and even some of the ones from Yell. For me, this role followed on nicely from Yell to a place that had implemented Agile at scale. There has been a lot of debate as to how Agile their approach was, but from my perspective, I was at a transition point from Waterfall into Agile and it was working, but it wasn’t easy. There were some great features though, especially where they’d applied an “Agile Mindset” to a “Waterfall Mechanism” which resulted in a more people-centric and communicative process.
For a while though, I’d been reading and learning about this new “Kanban Thingy”. It certainly had an appeal and I realised that I’d actually been using some of it’s practices in Scrum, so I decided to start injecting some Kanban tools in to Scrum (this was before I’d heard of Scrumban). I then managed to use this approach successfully in two Enterprise Architecture assessments for global organisations topped off by an Agile implementation of Agile Governance for SOA a few years ago.
As I went through this beginning of my Scrumban phase (which I’m still technically in) I had a dawning realisation: there is quite a disconnect between the work I do in Solutions, SOA and Enterprise Architecture (where I’ve used Agile, Scrum, Lean and Kanban most of the time over the last decade) and what I was reading and hearing about in “Cool Agile Land” (that’s where all the cool hipsters are xDD’ing ;).
It was then that I realised that there was just as much of a need in these areas – the problem was that this was not where the majority of “activity” was happening and that in general the mindset was more waterfall. There were however, some mavericks (who both backed and worked with me) like my self who believed that there was a middle path – we could use Agile techniques in Architecture in Big Organisations without conflict and hopefully start a revolution…
So far, I’ve only given you the 100,000ft view (as one would have with a Scramjet :)
A personal exploration of the use of Kanban, Scrum and Lean Principles to create a Service Oriented Architecture within a large organisation.
What does that really mean though? Why should you keep reading or even tell your friends? Like anything I do, this will be iterative, lean and hopefully have a good feedback cycle (it’s appreciated whenever you want as a comment here or tweet to me).
My immediate plans are that there will be two arcs:
- A personal narrative about Fellowship and hopefully some use of Antimatter in working with and transforming a team*
- Notes and guidelines around the use of lean/agile that I observe or think of along the journey
Anything could happen as I have no real plan for this except for the vision of a Skramjet
*Disclaimer: Any resemblance between the company, team and any people described in this narrative are purely co-incidental ;-)
A scramjet (supersonic combusting ramjet) is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic airflow.
A Skramjet (ScRuM, KAnban, lEan, Just in Time) is a process in which work takes place in a SuperPersonic flow state environment.

I’ve decided to do a bit of a “deep dive” in to the Fuse ESB, which is now owned by Red Hat, to upgrade my technical skills in this area. I’ve actually ended up using a product called Fuse Service Workbench instead of this and will eventually do a post similar to this on how to install it. The directions given here will work though if you want to set up “Basic Fuse” along with the Developer Studio.
One thing I have discovered (by getting FSW up and running) is that due to various bugs in Oracle’s JDK 1.7 on Apple – you should use it, at least for this. Instead, you need to use Apple’s JDK 1.6, making sure that you set JAVA_HOME to the real path, not a symbolically linked one (of which there are many). I’m assuming 1.7 is OK on Windows (as the doc says it should be) – feel free to let me know your experiences in the comments section.
For simplicity, I’m using the RedHad FUSE ESB which includes: Installers, Testing, Performance, Third party verification, Centralized management of uniquely configured brokers with Fuse Fabric and Incremental patching. It’s a 30 day trial, but I’m just using it for the quick and easy installation.
1. Install JBoss FUSE Beta (6.1)
Get it from http://www.jboss.org/products/fuse, unzip the file, uncomment the (last) admin user line from etc/users.properties:
and start the ESB, so you should get something like this:
JBoss-FUSE rwest$ bin/fuse Please wait while Fabric8 is loading... 100% [=============================================================] _ ____ ______ | | _ \ | ____| | | |_) | ___ ___ ___ | |__ _ _ ___ ___ _ | | _ < / _ \/ __/ __| | __| | | / __|/ _ \ | |__| | |_) | (_) \__ \__ \ | | | |_| \__ \ __/ \____/|____/ \___/|___/___/ |_| \__,_|___/\___| JBoss Fuse (6.1.0.redhat-328) http://www.redhat.com/products/jbossenterprisemiddleware/fuse/ Hit '<tab>' for a list of available commands and '[cmd] --help' for help on a specific command. Open a browser to http://localhost:8181 to access the management console Hit '<ctrl-d>' or 'osgi:shutdown' to shutdown JBoss Fuse.
As mentioned above, you can then go to http://localhost:8181 and login
which should give you the welcome screen!
Congratulations – you’ve almost got FUSE running as what you have at the moment is a Fabric, which is kind of like a ‘mini cloud’
Now you should shut FUSE down using
JBossFuse:karaf@root> osgi:shutdown Confirm: shutdown instance root (yes/no): yes JBossFuse:karaf@root> JBoss-FUSE rwest$
so you can …
2. Install JBoss Developer Studio 7.1
Get it from https://www.jboss.org/products/devstudio.html and just open it – as it’s a jar file, on a Mac (which I use) it will just run the installer:
If you’re on a Mac, then the JVM/JDK will probably be set to your browser’s JVM, which is not correct – it should be set to your JDK. In the case of Apple, it should be 1.6:
>> TODO: Update Diagram Below
Contrary to the screen above, you can use the “Visual Page Editor” on a Mac if you do a 32-bit installation. At the end you can then start the IDE and at a minimum you should install all of the “Integration Stack” items as some of these work with FUSE:
and there’s some pretty cool stuff such as support for Rules systems like Drools and Guvnor. You’ll probably get a warning about “unsigned content”, but that’s just someone (in Red Hat) being lazy.
After the installation, JBoss DevStudio will want to reboot and then you’ll be right for development with FUSE which we’ll cover in the next installment…
NOTE: Still a bit more updating to do, but most of the above should be correct.
It’s that time of year where everyone is reflecting on the last year, so I thought I’d toss my hat in to the ring. Personally, it’s been a year of great change, having moved from a highly toxic street in Reading (where our dog unfortunately passed away just before we left) to a beautiful one in Ashford where we are much more settled and I’m at last able to relax, grow and learn in a supportive environment.
That’s enough about me though, what about the IT Industry and wider world from my perspective?
- The year Apple Stumbled – It wasn’t just iMaps, it was the lack of innovation and wierd and frequent release schedules which all smacked of internal chaos – understandable given that Jobs passed away late the previous year, but they’ll need to get back on track if they want those stock options to be worth something
- The year Microsft Stumbled – two words: Windows 8 or Windows RT or Microsoft Surface. I must admit that I’m less disappointed with W8 than I though I would be – only going by playing with it in a store though as I’d never install it on any of my computers. It’s not over though, so the real question is what’s going to happen with W8 and Surface (Pro)
- SEMAT – Software Engineering Method and Theory has been pretty much defined by Ivar Jacobson and his merry band of Industry Legends and Corporations. It was favourably received by the OMG in December
- ArchiMate picks up steam – for me at least before this year, it was only occasionally being used, whereas now, many organisations are using it for Enterprise and Solution Designs and then linking these to UML Technical Designs and Realisations
- Clojure – I’ve been getting in to this and went to the London Skills Matter Clojure eXchange. Rather than a bunch of enthusiasts though, I met a bunch of enthusiasts, 1/2 of whom were working in Clojure! It seems this is probably an increase of a few hundred percent over the previous year, so something is happening. This may be part of the wider movement to “different” and sometimes functional languages.
- Light Table – at the moment this is only a Clojure IDE, which will be expanded to handle other languages, but I’m yet to be sold on it. The demo was really cool, but the releases won’t run my code (which obviously works in other environments) and the interface feels a bit too simple at the moment. They’ve got kickstarter funding, so here’s hoping that we start seeing more features and functionality from the original demo as it could be one of the best development environments ever!
- Raspberry Pi – how can this not be mentioned??? It’s a UK concept that is taking the world by storm and riding a wave that was started by Arduino, DreamPlug and the like. The great bit is that Raspberry Pi only opened the space, much as OLPC did for small cheap laptops. The side effects already are and I’m sure will be awesome
- FreedomBox, first proposed by Eben Moglen is gradually getting there. Not there yet, but it will get there and hopefully redress much of the planned snooping that governments around the world have fallen in love with
- The Maker Movement seemed to jump up a level with people even 3-D printing guns and starting to sue each other over who owns what and can sell it
- Fibre rollout in UK seems to be really happening and I’m liking what I see. I signed up on the minimal (and slowest) plan but it’s easily enough for me at 75G : ~ 30Mbps down and ~10Mbps up (real rather than pretend bandwidth). The great bit is for an extra £10 or so I can double those rates! The best way to get decent FTTC seems to be by going through a BT Reseller such as Xilo / Uno
- Nonviolent Communication – highlighted by Bob Marshall and created by Marshall Rosenberg, this seems to be gaining ground, along with concepts like Soft Power. This (hopeful) trend towards a kinder, gentler and more humane approach may hopefully only be the start
- Lot’s of Noise from the Quiet People ;-) There seems to be a pick up in dialogue about introversion and quietude – all good stuff
- The continuing Industrialisation of Agile. Agile stopped being done widely (in smaller numbers, but more effectively) ages ago. What we seem to have now is a bunch of PM’s who have done “Scrum” or “Agile” training and are operating using the same patterns – “I want that velocity increased next sprint!”
- The world didn’t end! This is not a unique phenomenon though. Apparently at the end of the last millennium, the church predicted the end of the world, and as a result waged a number of wars to convert the heathens to christianity before the end of days – sound familiar?
- Thinking we know How to Create a Mind – I’m writing a review of this, but overall it looks like Kurzweil may be right to the degree that we’ll have significant AI’s by the end of the next decade.
- The US (aka The United States of Goldman-Sachs) edging closer to becoming a fascist corporate regime with warrantless wiretapping, legalising of domestic drones and the effective elimination of Posse Comitatus. This doesn’t leave the populous (who all seem to be classified as “possible terrorists”) with (m?)any rights should the government and it’s “leaders” decide to “turn corporate nasty”. Many in the US such as Naomi Wolf have spoken out about such issues, so here’s hoping that humanity and openness prevail over fear and alienation
That’s pretty much it. We’re off this evening to watch the London fireworks on a cruisey boozy boat on the Thames, so I hope you all have / had a great NYE.
If you’re interested in IT, Privacy, Science, Maths, Process, Systems (of people and technical), Programming, Organisations and any other topics that grab my attention, then you may want to follow this.
I did have a site called Architectural musings (which I’ll be reposting content from) but thanks to much listening, twittering and thinking I’ve decided to broaden my remit a bit because I do work a lot with change and at the end of the day, most of my architectural work does involve change in some form.
Most of my work is in large corporates, doing either (or both of):
- Architecture (Yang): Enterprise, Solutions, SOA and Application / Technical (Java & J2EE)
- Process (Yin): Waterfall, V, Agile, Lean, Scrum, Kanban and anything else that seems useful
And just like in life, I’m after achieving some sort of balance :-)
