  • The Five Whys of Lean

    Root cause problem resolution is one of the core practises in agile. If the engine requires new oil every 500 km we don&#39;t just top it up with oil. We fix the engine.&nbsp; Adding oil is just a hack that leaves technical debt in the system and slows down our journey. It reduces our sustainable pace. Good operations people get this. Many ...

  • Why Going Faster Matters

    I did&nbsp;a talk on Value Stream Mapping from Lean last Thursday at the Danish Agile User Group&nbsp;meeting (slides in Danish are available at&nbsp;http://tech.groups.yahoo.com/group/DanishAgileUserGroup/files/&nbsp;(registration required)).&nbsp; One of the many interesting questions that came up was why faster is better - could it be that ...

  • The Waste of Defects - Bugs are Stop-the-Line Issues

    &quot;Don&#39;t clean it,&nbsp;&quot; my grandmother&nbsp;used to say; &quot;keep it clean.&quot;.&nbsp; She probably learned it long before the computer era.&nbsp;Yet for some reason her advice did not spread to the software industry.&nbsp;We still have a tendency to build up a big mess and put off cleaning it up until much later. I am thinking ...

  • re: Code Reviews and the Developer Handbook

    Andy Thanks for your comments. As a rule of thumb I think everything that is needed to build the system should be in placed under source control so I can set up a new machine by just fetching the project from source control and get going. So as you might have guessed we did indeed put the external libraries (NHibernate, Castle Project, Rhino ...

    The key principle in lean manufacturing is to eliminate waste. The Toyota Production System names seven major sources of waste.

  • re: Lean Software Development

    Mark, &quot;agile under fixed-price contracts&quot; is a great subject for a bigger post. Thanks. Maybe we will get back to that. Anyway, for now, there is a useful technique called &quot;exchange requests&quot; that allows the customer to be somewhat agile inside a fixed-price contract, namely by developing the application iteratively and ...

  • Lean Software Development

    Today the lean meme is in every business newspaper. It has been a long time coming. Some companies like Toyota have lived these principles since the 1950s when their lack of capital forced them to improve their production processes radically. In the West it appeared on the radar with the books by Womack &amp; Jones published from 1990 and onwards. ...

  • Going Agile - Introducing Inspect-and-Adapt Cycles

    Many large IT organizations are so inefficient that helping them go agile may seem like an incredible amount of work. The key to not being discouraged is taking the long view and following the advice for how to eat an elephant: it is &ldquo;one bite at a time&rdquo;. If we try to solve all the problems at once we will simply be overwhelmed by ...

  • Going Agile - Setting a Minimal Professional Standard

    Many agile processes are just that: Processes. However, one of the keys to success that is often overlooked is the technical project infrastructure, and the discipline and craftsmanship required by the team. While agile is lightweight it also sets the entry level for professional standards higher than many organizations are used to. It is all ...
