SDN Virtual Community Day

Last Thursday was my first webcast at SDN: Agile SAP, Mission Impossible? The replay is, just as the other sessions, available on SDN.
With a webcast it is a kind of difficult to interact with the people that are connected. Known pitfall is then to start talking faster and faster. I sure hope that the message got through. And for those who want to view the presentation again - it is available via SlideShare:


On the last slide some interesting links to more information are available.

During the session some questions arose in the chat window.
  • Use cases instead of user stories: We thought that user stories are very well applicable to web environments. But in our situation we also had a lot of backend functionality and processes to be realized. Therefore we decided to model everything with use cases.
  • Bigger size teams (>=100): Our team developed 1/3 of the total solution. The other teams did not work according to scrum. But if they did there is a scrum of scrums approach to share the information of all the scrum teams. Dagfinn Parnas: "scrum does scale very well, but it does require some extra thought with regards to organization, tools etc. Craig Larman has a few good books on the topic.
  • Using Scrum with non collocated teams: We were all located together, one of the biggest advantages for the project to minimize communication issues. So no experience yet. With online dashboards and nowadays conference call possibilities it can be made a success. As long as you keep to the basics of the approach: Working together during all phases of a sprint. I am curious to hear on experiences using Scrum and an offshore team.
  • How did the SAP team work together? An ABAP developer will not do CRM customizing. That's for sure. But everybody can help designing the solution, documenting and testing it. All team members are expected to help each other. We saw some pair programming activities during the project: CRM and ABAP consultant working together.
  • Resourcing scrum team: A project running at high speed needs a team that is almost 100% available. If not, people will miss a lot and have to catch up every time when they are back. Make sure that people that enter the team somewhere during the project that they get a proper introduction on how business is done within the scrum team.
Best advice according to Harald Reiter: Go out and do it!

Thanks to those who were attending my session. Feel free to share your thoughts on this topic with me.

September 24, 17:00 (GMT+1)
2009 Virtual Community Day
An SDN webcast open to everyone who is interested. After my slides I hope to have an interesting discussion with fellow SDNers on this topic. This will be my first webcast, I will try to prevent any technical flaws ;-) Follow the Twitter updates to get the link where the session is broadcasted.

Sander and I will do the “Agile SAP: Mission Impossible” show together for the first time. Hope we have enough time for all our slides and stories ;-)

October 27 – 29, SAP TechEd Vienna
During the SAP TechEd in Vienna I hope to find a timeslot to organize a meet up with other agile enthusiastic participants. Maybe we can find each other in the community clubhouse and have a cappuccino together.

November 25, 14:00
Landelijk Architectuur Congres 2009 (Dutch Architecture Congress)
Our story is divided in two sessions:
First mine: A recipe for an SAP SOA project: from spaghetti to lasagna.
Then Sander: Designing service oriented projects with smart use cases.

Currently I am busy starting up the next Agile SAP project at the Dutch Railways. But first we will do a review on our first project. The results will most certainly end up in a blog entry ;-)
