Are we becoming Software Architects dinosaurs?

What is an architect? What it does? why do you need them btw? Thats really depends on what you belive and how to you see systems.

The IT Industry have some common ground ideas, but often ideas get mixed with different interpretations of the terns and practices.

There are company that say stuff like an Java Architect or .NET Architect. I think this is worng, most likely they are senior developers in java or .net or a architect that knows one of this languages a real architect know more than one language for me. So an Architect is an architect is not an Java Architect. If you just know java could you be consider architect? Today a solution could be using several different technologies and stacks, would a pure vendor/language solution be ideal?

Why Management does not work on Agile?

Today everybody talks about agile, yeah agile is mainstream. Agile become "Management", scrum is better than waterfall but things are not working as they should.

I`m not staying you not need management. As you grown into a complex structure you will need coordination, costs control, and management is need as you get something bigger and complex.

But in order to get it right you need realize when and where you fit management. People talk a lot about scaling agile and i think is funny so little is about engineering. People talk about multiples teams, multiple Product owners, multiple work streams, multiple timezones and cultures but where is the engineering? Deming(The Big mind behind Lean) talk a lot about psychology and the ability to understand systems and they nature.  Go Google you will lots of things talking about teams and so little talking about stuff like: Culture, Engineering practices, software architecture(real one, not power points) and principles.

How do I learn?

Learning is very important. Companies dont pay attention on this. All training activities are so old fashion and people are wasting a lot of create skills because people are just working but they are nor learning.

So this is the first thing to me, work is about learning if you are not learning you are not working you are just being a machine and belive me a bad one because machines can do better repetitive task them us.  There are always a chance to learn something, the problem is that people dont make time to this, instead they are always using the same old tools and approaches. Because is easy an often people feel good to be in the comfort zone, i few awful if i dont learn something new every week actually i got sick.

SOA Contract Testing

One of the most important aspect of a SOA approach is testing. In order to get this right you should have several levels of tests, is very hard to match all things you should have just with unit tests.

If you think on abstractions a Service in Service Orientation(SO) it`s a composed by a service implementation and a contract.

A service could implement multiples contracts. I like to have one contract per service but there are scenarios where you could like to have more than one, for service aggregates or domain segregation cases.

So whats is a contract? For SOA contract is DATA, thats the real contract, but this could be seeing as many things, so i like to thing in some things to define what is the contract.  SOA is about Design so this could change depending of your main architecture design but in the way that i see it a contract would composed by the following elements.

Walking Dojo

I always did unconferences and coding dojos with people i do Coaching. So this time i tought about doing something different. So the ideas is do a unconference talk without computers or slides and do that walking since is spring in south of Brazil and the weather is great :-)

This photo you see is the cover of the event i created. This was very cool because as guys working with software we are always doing things with computers(thats great) but with that we dont stop and something is great to stop and relax and talk about ideas. The ideas was that everybody had to talk and was a simple walking conversation about some cool subject that have some links between each other. We did 2h walking and talking thats was amazing because we did 2 great things, 1 talk about ideas and 2 walk so was good for our mind and health as well. :-) So this is the first post that will explain some of the things i create as a coach, you can see the whole index here: Coaching Catalog.
