This is the tenth of 12 posts about the principles of agile software development. Purpose is to go back to the start of the agile manifesto (http://agilemanifesto.org/principles.html) and discuss the implementation of the 12 principles in real life software engineering.

According to a new survey by research and consulting firm Hurwitz & Associates, manual configuration errors are wreaking havoc across IT organizations, not only impacting developer and staff productivity, but also causing significant delays in the roll out of customer-facing web applications. These errors are resulting in application downtime costing companies as much as $72,000 per hour

Brent Simmons writes on the Anatomy Of A Feature , using his recent work in NetNewsWire to add support for the popular Instapaper service: It’s tempting to think that adding a feature like this is just about adding the functionality — but there’s a bunch more to it than that. Here you see the gory, deliberate details that a responsible developer must consider when adding even what seems like an incredibly “easy feature.” Without a doubt, the part of my job that slows me down the most is exactly this kind of consideration

As staff members set up or change appointments in the scheduling software, they will have the option of exporting this information into their personal calendar on their computer. As this is completed, the staff member will then receive an e-mail with their calendar attached for later viewing. By clicking on the email, they are able to add it to their calendar. Customers on the other hand may export their schedule of appointments to their own calendar as they receive confirmation e-mail. The appointment scheduling software allows at any time both the client and staff member can log in to view current schedules and appointments. Clients can print out or export their schedule of appointments at any time. Appointments Per Time Slot: Scheduling Software Depending on what type of company you have, you may schedule anywhere from one to several patients at one time. With our scheduling software you have the capability of scheduling and managing multiple patients in one time slot. A doctor may see several patients at one time so he or she would need the flexibility to schedule several patients in one time slot. The scheduling software also allows you to customize your appointment screen with tabs that list items such as reservations, customers, tours etc. For each block of time you can for example, name the task to be performed as it pertains to your business

There is an ongoing debate about best practices for configuration management between XML configuration with schema support versus Annotational meta data. I can make a valid argument either way so the choice really depends on each case and context. That said, I have been on large-scale enterprise migration project recently and having been 50% of the decision in that case to go with xml configuration over Annotations for the right reasons, now that the new, migrated application is getting huge,

I’ve been off filling my brain at the Stanford Graduate School of Business for the past two weeks, so I haven’t been able to post much. I have nevertheless managed to keep my Tweetstream going so, if you’re not already following me on Twitter , you may wish to consider doing so because I am changing my sharing pattern to include more Tweets based upon the realization that bit.ly makes it very easy to do so and that I only blog on somewhere between 5% and 25% of the topics that I throw on my to-blog list.

We’ll be hosting another DII workshop soon, and this one will be of special interest to those who want to understand the inner workings of MCE (Markup Compatibility and Extensibility) as defined in Part 3 of ISO/IEC 29500. We’ve used MCE for new functionality in documents created by Office 2010, and members of SC34 WG4 have expressed interest in understanding the details of our implementation. So we’re planning a workshop in Redmond on Friday, September 18, the day after the upcoming SC34 plenary in nearby Bellevue, to do a deep-dive review of how Office 2010 uses MCE. For those who aren’t familiar with MCE, here’s how it is described in the Scope clause of the standard (ISO/IEC 29500-3): This Part of ISO/IEC 29500 describes a set of conventions that are used by Office Open XML documents to clearly mark elements and attributes introduced by future versions or extensions of Office Open XML documents, while providing a method by which consumers can obtain a baseline version of the Office Open XML document (a version without extensions) for interoperability. By using MCE for the new functionality in Office 2010, we can deliver innovations like sparklines in Excel 2010 or new slide transitions in PowerPoint 2010, while maintaining compatibility with the Open XML standard. At this one-day event, members of the Word, Excel, PowerPoint and graphics teams will demonstrate these new capabilities and show how these new capabilities are stored in MCE alternate content blocks and extension lists

Brent Simmons writes beautifully about a frustration that most indie software developers can relate to: the payoff proposition. He highlights the all-too-common scenario where a user offers a cash bounty, $50 for instance, to add a particular feature: “The developers I know would rather rip up $50 bills, long sequences of them, than do something that, in their best judgment, is against the best interests of the software and its users.” This reminds me of a listener question from a soon-to-be-released episode of Core Intuition , the podcast I do with Manton Reece . The question asks, roughly, “how can managers who don’t code relate better to their programmer employees?” Non-coder managers and customers have a lot in common: they have a great vision for the future of a product, with little understanding of the work it will take to get there.
