Seriously. I recently spoke with a client who swears that software quality improved once they got rid of the QA team. Instead of making QA responsible for quality, they put the responsibility squarely on the backs of the developers producing the software. This seems to go against conventional wisdom about quality software and developers: Don't trust developers. Or, borrowing from Ronald Reagan, trust but verify.
This client is no slouch, either. The applications provide real-time market data for financial markets, and the client does more than 40 software releases per year. If the market data produced by an application were unavailable or inaccurate, then the financial market it serves would crumble. Availability and accuracy of information are absolute. This app can't go down, and it can't be wrong.
Why Does This Work?
The client said that this works because the developers know that they have 100% responsibility for the application. If it doesn't work, the developers can't say that "QA didn't catch the problem." There is no QA team to blame. The buck stops with the application development team. They better get it right, or heads will roll.
As British author Samuel Johnson famously put it, "The prospect of being hanged focuses the mind wonderfully."
What is the definition of an "application"? We are "applications development and delivery professionals" - surely we have this question nailed, don't we? The question keeps coming up in different contexts, and since there are many potential opinions, a blog is the perfect place to spur debate. Here are some (simplistic) questions to generate debate:
Is a Web page an application?
If not, how many Web pages does it take until I consider it an application - 10, 100, 1,000?
Does size matter? (Please behave yourselves with this one.)
Is the size of the code base a pertinent factor?
What about SharePoint sites, Access databases, and spreadsheets? Are they applications?
Where do COTS and packaged apps fit?
Does the technology I use affect the definition?
If I use a scripting language for a quick-and-dirty task, is that an application?
Does SOA erode the definition of an application?
Do we cease thinking about applications as entities and think about them more as containers that hold collections of SOA services?
How does open source affect the definition?
How does my role affect my perception of an application?
Do developers and users use similar definitions?
I have my opinions - in fact I just finished a draft piece of research on it that will be published in January, but what are your opinions?
A quick note on a big announcement today by IBM that is being rolled out as I write this. No, I don't have a crystal ball - my colleague Brad Day and I spent a day in Poughkeepsie in late June for the full scoop - provided under NDA. The announcement is massive, so I'll just lay out the high points and a few of my thoughts on what it means to apps folks. I'll leave the deeper I&O/technical details to Brad and others in subsequent posts and research. My goal here is to get a conversation going here on what it may mean to apps people in your IT shops.
What's in the zEnterprise announcement?
It's a new computing environment that unifies Linux, AIX, and z/OS on a new server complex that includes mainframe servers, x86, and Power7 blades under a single set of management software: the zEnterprise Unified Resource Manager (URM).
A 10 Gb private data network joins the new z server (z196) and zBX - an ensemble that houses racks of x86 and Power7 blades. It also includes an intra-ensemble network that is physically isolated from all networks, switches, and routers - permitting removal of blade firewalls.
One client claims a 12-to-1 reduction in network hops by eliminating blade firewalls.
The z196 permits up to 96 Quad-core 5.02 ghz processors, 80 available for customer use, and 112 blades.
What is the impact on applications people and application-platform choice?
zEnterprise is a monster announcement that heralds a long laundry list of improvements - it would be impossible to cover all of the ramifications in a single blog post; however, a brief glimpse of some of the most notable improvements that affect applications folks include (zEnterprise as compared to z10):
Many cloud computing services in the consumer space are per se for free. Even sophisticated platform-as-a-service (PaaS) environments are coming from most vendors with a free sandbox environment and start charging finally the productive use. The obvious question I hear from many vendors today is how to monetize platforms and applications in the cloud. The situation for established ISVs of business applications can be even worse: The cloud might significantly cannibalize existing license revenue streams. Thus a transformation of existing business models and vendor strategy is anything but easy.
Addressing this challenge, I'd like to point you to a Forrester workshop “Selling The Cloud” on 30th September in London.
The workshop will focus on a evaluating your “cloud readiness” and consequently help develop your cloud strategy through the use of a self assessment tool. This is a great opportunity to learn an effective method for improving the business results of any migration to a cloud-based service. You can actually predict which, if any, of your products will be successful in a cloud deployment.
The workshop will be hosted by Stefan Ried, Senior Analyst at Forrester and in case you’re interested, here’s a Web page with an agenda: View Workshop Details.
You can register right on the site or, if you’d like more information, you can contact an Event Sales Representative at +1 888/343-6786 or email@example.com
You can also simply leave a comment to this blog, asking any question to the event agenda and value.
Applications development people can't stand the Luddites in the operations group, and ops people hate those prima donas in apps dev - at least that's what we are led to believe. To explore the issue, two of my colleagues who write to the infrastructure and operations (I&O) role - Glenn O'Donnell and Evelyn (Hubbert) Oehrlich - invited me to participate in an experiment of sorts. They arranged a joint session for the I&O Forrester Leadership Board (FLB) meeting, and I was the sole applications guy in the room - a conduit for I&O FLB members to vent their frustration at their apps dev peers. For those who aren't aware, FLBs are communities of like-minded folks in the same role who meet several times a year to network, share their experiences, guide research, and address the issues that affect their role.
We infused the session with equal parts education, calls for joint strategic planning across all IT work, and a bit of stand-up comedy - Glenn noted that as representatives of our respective roles, he and I were actually twin sons of different mothers. I noted that in that context that our parents must have been really ugly. Once we opened the session for discussion, the good folks in the room wasted no time in launching verbal stones my way. Now, I'm no IT neophyte: I've been in the industry since 1982, and I'm no stranger to conflict - I grew up with 3 older brothers, and we all exchanged our fair share of abuse as siblings will. Still, I wasn't quite prepared for the venting that followed. To summarize a few of the main points, I&O sees apps folks as:
Recently, I discussed complexity with a banker working on measuring and managing complexity in a North American bank. His approach is very interesting: He found a way to operationalize complexity measurement and thus to provide concrete data to manage it. While I’m not in a position to disclose any more details, we also talked about the nature of complexity. In absence of any other definition of complexity, I offered a draft definition which I have assembled over time based on a number of “official” definitions. Complexity is the condition of:
OK, so the holidays are over, you've either closed, or are in the process of closing out 2009 year-end processing. The 2010 decade has begun, and it promises momentous change before we see the end of it: Leading edge technologies will become commonplace; Still newer technologies will emerge; New business threats and opportunities will arise; And the impact of the Baby Boomer phenomenon will finally arrive.
