We love Scrum at GigaSpaces

By |2020-10-12T07:45:16+00:00February 3, 2007|

It's been a while since my last post.
In the past few weeks I was very busy in kicking off the plans for GigaSpaces 6.0 due in the 3rd quarter 2007.

In this post I'd like to share with you my personal satisfaction with our decision to adopt Scrum as our product development methodology through 2006.
In few due-diligence I've been involved in the past couple of months with prospects (and now customers) who wanted to understand our development and quality management procedures, the discussion became very interesting when I described the way we implement Scrum at GigaSpaces.

The over-all is very positive. We currently have the spirit of an organization that constantly strives for improvement. Being a winning organization in spirit is not enough. We constantly monitor and measure our productivity and quality. We are able to identify the areas in our processes, collaborations and tools that need improvements. And we do improve those, right away!

For example, we've been working in the past couple of months on upgrading our automated testing framework. I've been assigning five of my top engineers and architects on a project with the objective to provide the development team fast feedback and monitors on quality.
Now we are able to identify specific source commits that either affect the product performance and stability. We identify those and fix them immediately. The turn-around is less than 48 hours of the cycle: code commit, failing test, fixed code and test verification. In 5.2 release, we needed only 3 weeks of stabilization, between feature freeze and the product GA release. Hopefully in 6.0 it will be even shorter than three weeks.

If you like to hear more on this, please drop me a line.

GigaSpaces 5.2 RC is out!

By |2020-10-12T07:55:45+00:00December 8, 2006|

After few night without proper sleep - I'm proud to say that GigaSpaces 5.2 RC is out.
Please refer to the release notes for a full description of the changes coming up.
Our next delivery is 5.2 GA - coming out by the end of the year.

We used scrum as our methodology for 5.2. It took us three sprints moving from 5.1 to 5.2. Over all, I'm very happy with the way we implemented scrum. We were able to show monthly incremental advancements and to constantly monitor both progress and quality. During this time the team was also able to respond to many customer requests coming in, and actually implement many of those in 5.2.

Some of the newest and coolest features of 5.2 are:

  • POJO enabled product
  • Support for slow consumer messaging scenarios
  • Continuous local view
  • Embedded workers bound to the space life-cycle
  • JMX focal server
  • Many SQL improvements
  • .NET PONO (Plain Old .NET Object) client
  • UI is now much more explicit on the information gives (notifications, transactions)
  • SELECT_FOR_UPDATE support
For a comprehensive list, please refer to the release notes.

I'm very proud of the team being able to execute in such great quality at this stressful time frame.

We have so many great plans for the future, and I believe we have found the balance between constant improvement of the little things to make our existing customers happy and moving forward with implementing on the Space Based Architecture road map.

Please feel free to try it out. Your feedback, as always is highly appreciated, and in this case extremely valuable for us to make 5.2 GA a great success.

I'm going to sleep the entire weekend, so until later ...
