Architecting for the Lines!

matt deacon — Tue, 15 Sep 2009 12:17:17 GMT

It is so often the case that integration is a secondary concern and along with identity, audit/logging and reporting it ends way below the fadistic significance of the UX in driving developer time (and cost). Not that I want to decry the importance of...(read more)

Mind the architect gap

matt deacon — Thu, 16 Jul 2009 14:14:30 GMT

I’m fortunate to know and work with a great many really influential architects both within my organisation and outside through my work as UK chair of the International Association of Software Architects (IASA). However, it has become increasingly apparent that for some the role of architects/architecture is clear while for others it is not. For me this begs the question that as organisations wake up, could there be and increasing gap between supply and demand of capable architects.

Back last year I commissioned some research with Freeform Dynamics to look at the difference between “progressive” IT organisations and followers. This clearly demonstrated a significant correlation between Architecture, integration and progressive IT. A more recent Forrester study shows the key role of Enterprise Architects in purchasing where “just fewer than 90% of IT execs said it was important, very important, or mandatory for EAs to approve technology purchases”. And back with the IASA, we ran a study with MWD Advisors that demonstrated the value of architects in design and implementation of BPM projects.

While these studies provide empirical evidence of the key role architects play in delivering business value do they also indicate and emerging gap between supply and demand of good architects? As more and more businesses seek architectural guidance will there be enough qualified architects to go round? Indeed this leads us on to what does a qualified architect look like and how do you spot one? Currently, this is measured by “time in service” or “battle scars” (I saw that on a job spec recently) but with corporate governance once again coming under the spotlight is this rule of thumb approach enough? can you trust mission critical systems to a guy with “battle scars”?

I know I’ve said this before, but is it time to we started to define the profession more accurately and perhaps more importantly, start to define the route(s) to becoming a professional? The millennials are rapidly taking over the asylum and out numbering the genXs (I’m one) and worse, the babyboomers are disappearing to the south of France and taking their “battle scars” with them. In many ways you can look at the future of technology in many ways looks similar to phases in the past but is anyone learning from their mistakes? Is anyone interested – you can bet that the milennials aren’t – how many of them have heard of “the mythical man-month” for example?

The Interoperability Files: Defining Interoperability and Integration Part 2

matt deacon — Mon, 06 Jul 2009 16:13:03 GMT

Ah Mr Nanni,

I am indeed humbled and excited at reading your reply to my posting on Defining Interoperability and Integration and for highlighting the apparent paradox in my definition. However, as to whether this leads us back to using the original definitions I am not sure I agree. It is not that I disagree with your points or that I think our views are that far apart but that this represents an opportunity for us to move the definition forward rather than to settle for second best with the current version.

On first glance, I think our differences can be explained by the fact that we are approaching the problem from different starting points. For my part I was viewing the problem from a System Integrator (bespoke development) perspective where as I think you are taking a particularly product centric view. This is not to indicate a flaw in your thinking but more in mine, for which I thank you greatly. In order for the requirement of integration to exist then there must exist at least two different ‘systems’ (immaterial of whether they were bought from a vendor or built in-house) that need to be integrated together in the first place. Therefore, taking a product centric position (irrespective of the source vendor or bespoke) does indeed make sense and I would agree that “interoperability is a quality of the system” and not of integration itself.

However, I think the fact that we started from these two different perspectives highlights a significant feature of interoperability that your definition does not capture. Taking the System Integrator view there is still much work to do to ensure that one system interoperates with the other even if the originator (vendor or in-house) of each system believes that each system is interoperable in of themselves. This ‘glue’ that exists to broker this integration must therefore be classified as a ‘system’ itself and therefore exhibits some quality of interoperability as do the systems themselves, that are being integrated. I think it is too easy to assume that by a product being to some level “interoperable” solves all the problems.

I think this is an important factor that should be reflected and while I agree in essence with your redefinition “Interoperability [of systems] is a condition sine qua non to achieve system Integration” I think it needs further extending to ensure the notion of “quality” is maintained. With this in mind I propose the following definition for interoperability, with the changes to my original as listed.

- As discussed interoperability now relates to the system (or organisation).

- Quality Attribute is a common architectural term that I have decided this time round to introduce and to replace the word “property”.

- “facilitates” to replace “ensures”

- “a level of independence” removed from definition.

Interoperability is a quality attribute of a system (or organisation) that facilitates the integration between it and other existing and future systems (or organizations).

As for the definition of integration, there may be a “temporal dichotomy” but if this is the case then surely that is true of the original definition. Therefore, it is clearly not right for us to revert back to the original. Perhaps I do not fully understand the dichotomy you talk of here so until I receive further clarification I recommend the use of my original definition.

Integration is the process of linking together diverse systems or organizations

This now brings me to your final Zen comment. I am unfortunately not one for remembering quotes however, one that does come to mind given we share the name which (and please do not read too much into this) is a quote from Matthew 15:14:

”If the blind lead the blind, both shall fall into the ditch.”

Ok, so now I got to hunting around so how about these pearls of wisdom from Isaac Asimov:

“If knowledge can create problems, it is not through ignorance that we can solve them.”

I guess what I am thinking here is that it is a good idea to try and get some definition here …

Bletchley Park Architects Council Part 2

matt deacon — Mon, 06 Jul 2009 11:43:11 GMT

The Microsoft UK Architect Council Meeting
8 & 9 June 2009
Bletchley Park, Milton Keynes

On the afternoon of the second day the Council broke into 3 groups to discuss interoperability in the context of

Security & Identity
Standards
SOA

The groups were asked to consider the following questions:

What does interoperability mean and what is its relevance to this area?
What are your experiences on interoperability in this area?
What are the challenges/opportunities?
What the outcomes being achieved through interoperability in relation to this area?
What does interoperability have to deliver?

And were asked to respond from a Business, Application and Infrastructure/Technology Architecture perspective.

Their output was captured/consolidated as powerpoints and their playback recorded. The output is provided below.

Bletchley Park Architects Council Part 1

matt deacon — Mon, 06 Jul 2009 11:42:19 GMT

Microsoft UK Architect Council Meeting
8 & 9 June 2009
Bletchley Park, Milton Keynes

In June 2009 a group of senior IT Architects from across the industry assembled at Bletchley Park, the home of the World War II code breakers for two days to discuss the current state and requirements for interoperability, standards, security and service-orientation across the IT industry. Bletchley offered a more than fitting venue to discuss and debate these subjects given its history and the incredible achievements they made.

Welcome to Bletchley Park

Dave Gristwood and I chew the fat before the two day meeting takes place to talk about what we’re going to be discussing and why Bletchley was such a great place to be doing this.

But don’t let this stop you from viewing as there is then a great welcome from Simon Greenish, Trust Director at Bletchley Park who really made a special effort for us during our stay and who continues to be the driving force behind the growing success that is Bletchley Park today!

A quick view of Bletchley Park

Bletchley is a key part of our cultural and scientific heritage and for the computer industry stands out, not only as the scene of some of the most amazing code breaking stories of WWII that undoubtedly reduced the duration of the war by some considerable time but also as the birth place of modern computing.

We all owe much to Simon and his team at Bletchley for the incredible job they are doing to not only save this for us and future generations but in so doing enable us to learn from the lessons of Bletchley and the work that went on there during the War!

However, it should be noted that Bletchley remains under threat and I would impress on all the importance of your roll in ensuring its continued survival and future success.

Many thanks in particular to our guide David Whitchurch and also to Tony Sale for demonstrating how Colosus boots faster than his copy of XP!

So what is Interoperability anyway?

Interoperability means many things to many people but here just a few thoughts from the architects who met at Bletchley to discuss the subject …

The presentations …

The interoperability imperative

Giampiero Nanni, Director of Interoperability, Microsoft Ltd

Interoperability is at the same time a challenge and an opportunity for organisations, private and public, with implications that go way beyond the pure technical aspects and issues. Microsoft is committed to solve these challenges, starting from weaving Interoperability into the fabric of the company, and through a collaborative approach with the different communities, government and standard bodies

Standards and software – combining innovation and interoperability

John Phillips, UK National Standards Officer, Microsoft Ltd

The vibrancy and innovation of the software industry is incredible. It has created the modern tools needed by competitive enterprises. But raw innovation in the modern multi-vendor, multi-domain environment can challenge interoperability as implementers interpret standards in different ways. The advanced software architect needs to combine innovation and interoperability in complex systems to keep customers happy. This session will explore the challenges today’s standardisers in the software domain may face in building a standardizing capability for system-wide interoperability.

Lessons from Bletchley

Ian Race, Senior Architect, Merrill Lynch Bank of America

Rupert Brown, Senior Architect, Merrill Lynch Bank of America

Why is it that so many software projects fail? As the Standish Group's 2009 CHAOS report confirms, this record is getting worse, with only 32% of projects delivered on time, on budget, with all required features. 44% were challenged being late, over budget, and/or with less than the required features and 24% failed or cancelled prior to completion.

Bletchley represents enormous success by a relatively small group of contributors in a relatively short period of time. Was this just luck or judgement? Are their lessons we can learn? Taking a couple of assumptions into account the council represents well over 800 years combined IT experience, during this time there have probably been one or two successes? Is there anyway we can capture some of this collective wisdom and turn it into a form that could save current and future projects from failure?

University Challenge

Keith Straughan, Dean, University College Milton Keynes

Earlier this year the Higher Education Funding Council for England proposed a new University Challenge to 'unlock Britain’s talent" to support the Government’s aspiration to see up to twenty new Higher Education Centres in the UK. In many ways Milton Keynes is a natural choice, but perhaps rather than just proposing itself as being another University why not take a step back and maybe consider what the University of Tomorrow might look like. What if it were to really harness the power of modern technology? What would this 'virtual' university look like? Keith and his team have been spending some time thinking about this problem and have come up with some interesting thoughts.

Security Strategy Briefing

Ed Gibson, Chief Security Advisor, Microsoft Ltd

Ed gave a free flowing account of the state of security across the industry. He covered many of the industries top security challenges, a new economy action plan, and described Microsoft’s strategy in relation to Trustworthy Computing and the Security Development Lifecycle.

Security Intelligence Report

Cliff Evans, Security and Privacy Lead, Microsoft Ltd

Cliff provided his perspective on the changing threat landscape including software vulnerability disclosures and exploits, malicious software (malware), and potentially unwanted software. Using data derived from hundreds of millions of Windows users, and some of the busiest online services on the Internet, this session will provide an analysis of the threat landscape and the changing face of threats and countermeasures, including information on privacy and breach notifications.

SOA is Rubbish

Jon Collins, Managing Director, Freeform Dynamics

"SOA is Rubbish", "SOA is Dead", "SOA: Lives with Elvis" are just a few of the recent headlines from analysts and press over recent months provoking the debate on whether the great white hope of SOA has ever really materialised? What is the SOA ROI? But SOA has ridden worse storms over the many Gartner hype years than this. What is the state of play? Maybe the truth is we're doing this anyway, leave us alone! Just stop calling in SOA and stop getting my CEO all excited about nothing!
