Weekly agile links 28th June - 2nd July 2010

Adventures in Accelerated Learning If you're in the business of spreading knowledge in one way or another, if you're a change agent, trainer or coach or you simply want to learn an effective way to tell a tell then you should read this article. I also highly recommend the 2 books mentioned.

Guidelines for Group Collaboration and Emergence Trust, Respect, Participation, Comittment.. A brilliant article by Venessa Miemis.. for me it created a lot broader understanding of something I've already read about elsewhere. Thanks.

12 Things the Best Bosses Believe I believe in certain things about being a great leader so this one naturally caught my attention. I find this to be a Great list with very useful reminders.

Identifying Waste Lean Thinker says “Make less, buy less, use less, throw away less.”. Sounds reasonable to me :)

Kate Oneal: Productivity 2 years old and still very relevant. From XProgramming.

Cultivate Informal Leadership Jurgen Appelo's article gives some practical advice about leadership that is worth having.

Understand Technical Debt by Playing a Game - Packing Peanuts This game sounds great fun and looks like it will demonstrate technical debt. Thanks for sharing Masa!

Risk Management Methodology Ray W. Frohnhoefer provides some useful guidance that can be used to do risk management in agile (I know, I know "agile is risk management" yet I am regularly asked how do you do it?)

A MANAGER’S GUIDE TO GETTING FEEDBACK A new article by Esther Derby. Incidentally I participated in a similar discussion on one of the agile user group boards.

How can we encourage active participation in groups after the original excitement of forming has died down? an article on Collective Self by lori which suggests that self-organizing work groups don’t live on indefinitely. I'd agree with that. Useful ideas about what options are available once you're in this situation.

Making TDD Stick: Problems and Solutions for AdoptersMark Levison's article about TDD is not about 18 months old. Still plenty of relevant ideas, some not always practical. I'd add BDD at the top of the list.

The Estimate Goat The only bad thing about this site is that I have not discovered it earlier. Great tool to give you estimates!

Your Project Needs Business Rules, Not Meetings To be honest I cannot be bothered to read this one right now and hence I will not comment on it. I am including the link as I might need it later and it does sound controversial which usually means there might be some good ideas in it.

SQL Server: Searching data in all tables in multiple databases

Recently, I had to deal with a weird issue which was related to possible invalid references stored in a database. I did not know much about this database so in order to remove these instances I wanted to search through all the tables in all the databases for a specific fairly long and definitely unique string value.

Then I came across this article which suggests a great solution for searching within a single database, however I had a fair amount of databases to look through so instead I wanted to see if with a little bit of tweaking I could make it work for multiple databases. It turned out I can and I thought I'd share the result.

So below is a stored procedure that you need somewhere on the server (db not important) that will search through all the tables in each of the databases you supply as a comma delimited string. You could also rework this to be a simple script rather than a stored procedure if that suits you better.

I hope it does come useful ;)

Weekly Agile Links 14th-18th June

Some more links from the past week. things continue to be extra busy with plenty going on and finding it difficult to spend time reading.. too bad :(

Lean-agile dogs: Are we chasing the right car? One more Scrum/Kanban article by Pascal Pinck.. some interesting thoughts on what is important.

AGILE PRINCIPLES REVISITED This is results from a survey asking respondents to rate how important is each of the original agile manifesto principles along with other stuff like what is essential to be considered agile. Interesting idea but they all are .. no really, they are.. Also no mention that being agile based on these results may simply mean nothing.

Animating a Blockbuster: How Pixar Built Toy Story 3 A very Scrum/Agile like process although does not mention the words.. according to e very reliable source who has actually read it ;)

Weekly Agile Links 7-11th June 2010

Have I said busy in the last weeks? I obviously did not understand the meaning of the word! Anyway, I will still be collecting links and posting them here for the same reasons I started these posts and if it happens that someone finds these useful then even better. Here's my modest collection from last week. Enjoy ;)

Using an Agile Software Process with Offshore Development Martin Fowler writes about his experience with off-shore development in Bangalore. Always interesting to read what he has to say..

A Fundamental Turn Toward Concurrency in Software See, this article is 5 years old and I feel I should have read it a while back.. it is worth a bit of time ;)

June 8, 1637: Descartes Codifies Scientific Method very interesting read by Lisa Grossman

Maximum Viable Product Bradford Cross on product management, looking at some successful products & companies, looks a good read.

Belts and Tools Not Needed to Improve Service Article by Tripp Babbitt related to Systems Thinking Concepts. Generally I like the system thinking ideas.

Another busy week of very little time for links.. hopefully a few good ones below..
just one more week of madness and should be able to provide better quality comments ;)

Enjoy ..

Right.. here's another manifesto suggestion Next step of the Agile Manifesto? What is it? the Manifestos year? Otherwise this one has sensible suggestions.. I agree.

What Motivates People? No huge secrets revealed in this one. PAWEL BRODZINSKI states a truth everyone would sooner or later establish. Once you step on that road of course.. might be better staying off it longer term tbh.

Jeff Bezos and Root Cause Analysis Real 5 whys example (apparently).

SHIFTING THE PATTERN: A SYSTEMS APPROACH TO CHANGE The title kind of explains it.. Esther Derby talks about change and systems thinking..


The "Command and Control" Military Gets Agile Interesting article by Dan Mezick about what happens when the usually inflexible military 'gets' agile
