Agile

It's the topic that stirs much emotion in the software development field. Being in the field for 30+ years I've had the opportunity to be involved with many different types of development methodologies with Agile only being the latest among them. Each of them have aspects that are shared but may be implemented differently in different phases of the development lifecycle and Agile is no different.

The need to gather and understand the customers requirements, the need to track progress during coding and to verify the operational aspects of the work thus far. All of these aspects exist in different methodologies to different degrees. My personal perspectives on Agile are:

  • It’s not the holy grail of development methodologies. 
  • It tries to instill from a process what good concerned developers should already contain and just using a different process will not over come developers ill suited for a project. 
  • It tries to instill a mantra that could be perceived as “somewhat” of a religion. It’s this last issue that most disturbs me, as this could blind people to the issues that need to be addressed for any given project. 
Any development methodology can not remove it’s self from the company, people and teams that it effects. Any selected methodology must be flexible for the needs not of just the developers but of project management, QA and the people that are involved in all aspects of the project. It cannot remove it’s self from the need of a sound foundation and no amount of refactoring (which can lead to a type of thrashing), tests or strict adherence to any methodology will make up for this. Foundations such as: 1) starting with a well thought out architecture and development structure, 2) having the goal of providing the company (they are your first customer) and the end user with a usable solution (a product or service) and 3) guiding well matched staff to develop the product.

Any development methodology should not be an end unto it's self instead of just another tool.

There is no "Right" way.

It's not that your way is not the right way, it's that everyone has their own right way.  So which is the right way?  Is there a right way? Software development is full of discussions that revolve about the "right" way of doing something. The terms used in discussing software design, tools and implementation are so undefined as to make them meaningless.  Code is not designed and written in a vacuum, it's designed by real people in real companies, each with their own constraints and issues.  Code that may look like a hack could have been the result of an employee dragged out of bed at 2am by a company shirt that only cared that they they did not lose their personal client the next morning.  Everything must be looked at in context.  A project written to "Best Practices" may never be finished before development funding dries up.   Goals, vision, constraints and thoughts should be somewhat aligned for project to be successful (or at least enjoyable ...

3rd Try is a Charm

I've been trying to draw / paint these barns for a couple of years but never felt or got them right.  This time I think they turned out right. So What went wrong before and what's right now with this drawing?  This time, the light was right.  It's coming from the upper right and the shadows just looked right.  The other thing is the corn field on the left had to "be in season", otherwise it's just a plowed field.  I had taken other photos from different angles but they never felt right.  This angle has the road, power lines, corn field, etc. all leading to the right.  The shadows on the lower right helps fill in that corner (don't forget about the corners!).  The last part is trying to draw (ink paint maybe) the trees in the background.  Not so easy when they are kind of a blob is green shades. So yeah, it's composition that is king.  Many times I just don't see it until the drawing / painting is finished and when it's right it feels goo...

So THIS is My Style?

 If I play around long enough my style will appear.  I'm guessing that this is kind of it.  I'll keep working on other techniques in watercolor but for now this appears to be my style. I do like it and others appear (to my face) to also like this.  Not every one of my paintings is a success.  About 1/3 so far, but when they do I am rather pleased that anything good comes out of it at all. I do love color.  Color is happy and outdoors is full of color, be it the west or back east with the greens.  Color color color. Also doing some painting on hot press paper and see how that goes. Later......
