So, this many posts in and I am still less than 5 years into my career... but an important shift in the story is imminent.
As I came off pure programming work like the new devevelopment project I have been describing, the Analyst part of my Programmer/Analyst job title started to dominate. Some of it was the work I moved on to, but also a parallel path of training that the company paid to have me attend. Everyone has a complaint or two about anywhere they have worked, but my first employer did understand that training was vital to the development and overall happiness of their employees.
Some of the training was general skills, like public speaking and on giving presentations. On the IT side of things, structured techniques were all the rage, broken into the parts of Structured Analysis and Structured Design. As I was still primarily a programmer, I recall I attended a Structured Design course first; it was given by an external vendor. The actual diagrams and techniques have faded from memory, but I do recall it is where I first learned about"high cohesion" and "low coupling". The course also showed how it used the results of Structured Analysis as input to Structured Design.
So, I continued along, doing enhancement work on existing systems. Understanding what the business wanted out of the enhancement, and then determining the impact it would have a on a system was the majority of the work; the actual programming work needed could often be minimal. So, it seemed like maybe I was turning into an Analyst who programs a little. I think the company did have the Business Analyst job title already, so I veered my career path towards that title.
That meant I got to attend the next offering of Structured Analysis training. The course used one of the era's gurus as a basis for the course: DeMarco or Constantine or Yourdon or whomever. I should have kept my course material, it would be a classic now!
It was on this training I was first introduced to the Data Flow Diagram, orDFD. The idea of diagramming what your system should do really appealed to me, even if the diagrams were hand-drawn and hard to change. Pencils and erasers is what I remember of the course and subsequent work back at the office. That would have caused a lot of people to use it less or stop using it, but not me. My future was being defined right there in that course.
Next time - the next big project
