In the software community, Ward Cunningham has a reputation for being a font of ideas. He invented CRC Cards, a technique that facilitates object discovery. He invented the worlds first wiki, a web-based collaborative writing tool, to facilitate the discovery and documentation of software patterns. Most recently, Cunningham is credited with being the primary inspiration behind many of the techniques of Extreme Programming. link

About the $200M Oracle-Ford Desaster: the management did not give them enough power to go fully agile

Chet Hendrickson:

 It was a very frustrating situation.  The team asked Don and me
 to help with preventing the Oracle consutants from making changes
 directly to the production system.  This was about $150 million into the project.

 We tried to sell them on a more agile approach (as you might imagine), but by
 this time they were pretty far gone.

 It was unfortunante that we were not operating at a level in the organization
 that would have allowed us to get the plug pulled sooner.

Georg Tuparev has a nice case story, too: speak out if you are put on a death march.

 Few years ago I was called to lead a huge team stuck in one and half
 year design phase. The team was supposed to build a control software
 for a network of telecom satellites. Cannot disclosed names and
 resources, but one could imagine ...

 Three days in the project I had a phone conference with the CxO's of
 both companies involved. Told them that the way it is going no
 satellite will ever fly and that I know a better way. After getting
 green line, the design document was burned with a small celebration at
 a BBQ, and 85% of the initial team members were sent to an indefinitely
 long vacation. With the rest (15%) of the team we had the first
 functioning version 2 months ahead of the schedule and 50% lower then
 expected expenses.

 So the lessons:
 - it is never late to change direction of a project in order to save it.
 - I do not agree with Kent that this is a sad story. If you are a good
 programmer put on a death march project you should speak out! If no one
 listens - walk away. There is just one very precious life in front of
 us - do not waste it! And if these folks wasted 2 years of their lives,
 well, it is their business ... but they should not expect my
 sympathies.

 BTW, Philip is right - the project I was telling about had a 9 months x
 40 people "Big Requirements Up Front"!!! Then the design started...

 Just my 0.02

I think that to get a group to be agile, you have to get people to do something like one of these things:

1. Go in that room there and do all 12 XP practices until you actually do know better. (XP)
2. Go in that room there, don’t let anyone screw with you, work on whatever you think you can get done for a month. Keep doing that until everyone is happy. (Scrum)
3. Go in that room there, in peace love and understanding, ship software every month (*), and think about it. (Crystal Clear.)

There is a telling sameness to all of these, is there not? —> This is a wonderful summary of a summary! There’s not much to be removed (see Saint-Exupery, below). In Italian, the expresso of an espresso is called a "ristretto" (any Italians online?). This is the agile ristretto. It belongs on a Blog or something. "La perfection est atteinte non quand il ne reste rien a ajouter, mais quand il ne reste rien a enlever." (Saint-Exupery)

Sabre Airline Solutions had many years of experience with its AirFlite Profit Manager, a big modeling and forecasting package that many airlines use to wring more income out of flight schedules. Even so, Release 8 of the software was four months late in 2000 after final system testing turned up 300 bugs. The first customer found 26 more bugs in the first three days of its acceptance testing, and subsequent joint testing by Sabre and the customer uncovered an additional 200 defects. www.computerworld.com/softwaretopics/software/story/0,10801,91646,00.html

How can software development productivity be increased? Through the same approaches used in operations: a focus on customer value, a short, effective supply chain, healthy discipline, and innovation. Mary will discuss techniques that businesses have used for decades to jump-start an increase productivity, and show how they can be used to increase software development productivity. pdf

1) Simplicity-the design must be simple, both in implementation and interface. It is more important for the interface to be simple than the implementation.

2) Correctness-the design must be correct in all observable aspects. Incorrectness is simply not allowed.

3) Consistency-the design must not be inconsistent. A design is allowed to be slightly less simple and less complete to avoid inconsistency. Consistency is as important as correctness.

4) Completeness-the design must cover as many important situations as is practical. All reasonably expected cases must be covered. Simplicity is not allowed to overly reduce completeness.

DataVision is an Open Source reporting tool similar to Crystal Reports. Reports can be designed using a drag-and-drop GUI. They may be run, viewed, and printed from the application or exported as HTML, XML, PDF, LaTeX2e, DocBook, or tab- or comma-delimited text files. The output files produced by LaTeX2e and DocBook can in turn be used to produce PDF, text, HTML, PostScript, and more.

DataVision is written in Java and uses JRuby to add Ruby scripting.

I always enjoy reading his weblog.

I just now came across the rubyx website and noticed the logo. Nice!

Rubyx is a Linux-distribution similar to Gentoo, but all based on one ruby script :-).

The pics shows "history flow" from IBM research. Tons of other good links can be found in the c2-wiki.

Visualising is really interesting and up for a major change. I am totally sick of all these boring search-engines out there and yeah, grep -r is still my best friend. Another reason why I despise MS-Word, he, he and use LaTeX. It took me years to fall in love with that programming-language, which happens to be a word-processor, too.

I still remember my first ray traced spheres on old XTs 15 years ago :-).

There is a competition and the monthly irtc. See the May-June viewing page and relax.

Computers are a grate time-killer, especially once you get into 3D images and animations. Enjoy it!

The organisation will next week show off a Wi-Fi enabled bus at the Paris-hosted Public Transport Exhibition 2004. It will also launch a public trial of the technology, on the number 38 bus, which runs between North and South Paris. Buses on the route have already been equipped with Wi-Fi, RATP said. Travellers will be able to connect their (suitably equipped) PDAs and notebooks with the bus’ on-board access point. However, Internet connectivity is only provided at Wi-Fi speeds when the vehicle passes within range of a fixed hotspot - at a major terminus, for example. For the rest of the journey, connectivity is maintained through a GPRS link. link

When an organization wants more than the Agile process requires, it is easy to show the additional cost each iteration, and as the team builds credibility the customer/stakeholder(s) might be less inclined to want to spend money each iteration producing documentation.

So have some courage, tell your stakeholders that they can have it (whatever "it" is) if they want it and then make sure you follow up with giving them a good picture of the cost and value they get from "it". It’s their money - let them blow it if they want to. Let them slow the velocity by asking for non-code related items. All you can do is make it visible and help them down the path of figuring it out.

The sooner you start delivering some working code, the sooner you’ll have the credibility to address their real process issues. "It" will become less important the more iterations you deliver working tested code.

The hard part is getting code started, right? Maybe you can disguise the first few iterations as "prototyping" and use TDD as the process for your prototyping? :-)
