What Drives Me by Ivar Jacobson

What Drives Me

“The best way to predict the future is to invent it!“ (Alan Kay)

A few days ago, a very simple but thought provoking question was raised to me: “what it is that drives me?” The simple truth is that I do not know. But I do know what it is that does not drive me. It is not about money. Actually, never has it been about money. Neither is it about power. I am happy to step aside and I am happy to delegate both up and down. It is not about popularity – but I do like to be appreciated for what I do.

No, it has to do with helping others improve themselves over and over again. I get a kick out of seeing others become successful because I helped them. It was like that in the late 1960s and the ‘70s when the Ericsson AXE system beat all competition and won every contract thanks to being component-based. Similarly, when Rational was successful because of UML and Objectory. And Telelogic because of SDL. I am happy when people are successful thanks to use cases.

Aspect Oriented Development by Ivar Jacobson

September 8, 2003

Last week I gave a talk on aspect-oriented software development at an IBM conference on this subject in Yorktown Heights. Last time I was at this IBM facility was in 1984 when I spent a year as a visiting scientist at MIT. IBM then offered me a job doing research in language development (Prolog-based). I was very excited about moving permanently to the US and so was my family. However, I decided to go back to Sweden to complete my thesis and get a Ph.D. If not, I probably wouldn't have founded Objectory, which was acquired by Rational, which in its turn was acquired by IBM. However, the "end" result was almost the same - working for IBM :-). I am now an executive technical consultant of IBM.

I believe that aspect technology will dramatically improve the way software is developed. I have described this technology as 'the missing link' to keep use cases separate all the way from requirements to code and test. I have written several papers on this subject. Right now I am working on a new book on aspects & use cases.

Last week I gave the same talk on Aspects & Use Cases at the Rational User Conference in Orlando. It was a very well organized conference - a lot of good technical stuff as well as a good portion of fun.

The conference was in Disney World, Orlando, so there were lots of opportunities for having fun. One evening we were dancing at the hotel. Great Caribbean music. The bad part was that the music had to stop at 10 pm! There is no doubt that the interest for aspect-oriented programming (AOP) is growing dramatically. The good news is that the use-case driven development approach is a perfect fit with AOP. To make AOP successful, it needs a methodology. We have such a methodology. Still, it will take a few years before tools support this technology.

At the same conference Jaczone (www.jaczone.com) demonstrated WayPointer. WayPointer really got a lot of attention. All the time there were people waiting to get a demo. What is so exciting is that WayPointer makes process active and at the same time practically invisible. This is done, by using intelligent agents to support developers in the many micro-activities in software development.

Aspects and agents will be important complementary technologies for the next years to come. You should take the time to learn about them.
