Engineer or Programmer? The (non existent) Existential Dilemma…


EVERYTHING

This article describes my opinion of the term and title ‘software engineer’ and the implications behind it, and how it ties (or should tie in) to the viewpoints of the engineering discipline at large. (Blog header illustration created using canva)

I very rarely spend attention on philosophical debates relating to software development, but last week I was reading an article I came across at ‘The Atlantic’, which prompted a train of thought, including this blog post. I suggest you read it before continuing, as it has a very interesting premise on why programmers should not call themselves (software) engineers. I neither agree nor disagree with the author or the article, but it had some very interesting ideas, that motivated me to document my thoughts and opinions in this post…

First, a bit about the term ‘software engineering’ from my own perspective and understanding. Throughout my career, I used to work with people who were (are) referred to as software engineers, themselves being graduates of computer science, information systems, or software engineering, the titles being appropriated to the name of the undergraduate degree that each followed in his or her academic journey. I myself hold a degree in ‘software engineering’ issued by a well known university situated around Regent street, north-west of central London in the United Kingdom. Therefore, the term or title ‘software engineer’ was something I was (and am) quite comfortable with, whether in how I introduce myself, or how I refer to my colleagues.

On the origins of the term ‘software engineering’, the article in question quotes a fact that is commonly taught in the industry and field of software development today, which is that the term ‘software engineering’ was first deliberately used in the 1968 Garmisch-Partenkirchen conference organized by NATO. It is said that the term was coined provocatively, in a bid to challenge software development at the time to align with the rigid processes and methods followed by the established branches of engineering. But it was interesting for me to come across an article by Bertrand Meyer, that provides some evidence and basis that the term was used at least two years prior to the NATO conference, and in positive light, indicating (at the time) that software development should be considered an engineering discipline in its own right.

The established engineering disciplines, are coined as ‘established’ based on the rigid processes, regulatory bodies, certifications, licenses, continuous learning, and ethical codes they follow. I am quite firm in my understanding that this is a good thing. But some of these aspects came about mainly due to the problems and engineering disasters that were prevalent in the 19th and 20th centuries, and saw the need to bring in standards, ethics, regulations, certifications and the rest. There is always a scenario which prompts the need for better processes, regulations, and policies. This was widely characterized in the software development world in the last two decades, where a myriad of development philosophies and approaches were invented. Even Robert C. Martin discusses about the situation, and tries to convey the message that if software developers (engineers?) don’t start getting there act together, we will be imprisoned by regulations and policies dictating how we should develop software.

If the practice and business of developing software is expected to evolve into an (established) engineering discipline, the progress will always be compared to the other mature engineering disciplines. This outlook and comparision was not favoured by some, which resulted in a large number of software development circles stating that software is more art/craft/science than engineering, and that there are better ways to build software than using rigid engineering processes. This viewpoint is widely respected and quite popular in the software development world today. On this side of the wall, software development should be lean, agile, and dynamic, without heavy weight engineering processes and regulations retarding these ideas, which is practical for all sense and purposes. Software is an artifact and material unlike anything that traditional engineers are used to working with, and early lessons taught us that building software  to specifications with rigid processes containing blueprints and schematics was not the best way to go about things. But the problem was (and still is) that the computing infrastructure (used by the public, consumers, clients, business users etc.) which is the end product of software development, still requires the same rigidity, reliability, safety, and conformance that a bridge or building built by a civil engineer should have. This is expected by a society which functions daily on the trust and understanding placed on the infrastructure around them, built by engineers. And therein lies the disdain towards the software development world (mostly by the engineering community, I suppose), where systems go wrong, bugs seem to evolve and reproduce, and software development is an activity that seems random and haphazard. The engineering world has its fair share of problems and disasters, just as there are software project failures and disasters. But a crucial difference is that the engineering disciplines will emphasize and priorotize the regulations, standards, safety to public health, and ethics, even if failing to deliver.

Just as engineering has foundations in the natural sciences, software ‘engineering’ too, has its origins in philosophy, mathematical logic, and various other branches of science, that has no direct correlation to what we do today as developers of software. The early proponents and pioneers who set the stage for software development to be a wide spread phenomenon, were computer scientists, mathematicians, particle physisicts, and information theorists. Not engineers per se. I was searching online and came across the professional engineers ontario website, where the definition of a professional engineering was formally stated. Based on my reading, I specifically chose canada as they are one of the countries who are extremely strict with the title ‘engineer’ and who is licensed to carry it. I would like to directly quote the definition of the practice of engineering, taken from their website:

Professional engineering is:

  1. any act of planning, designing, composing, evaluating, advising, reporting, directing or supervising (or the managing of any such act);

  2. that requires the application of engineering principles; and

  3. concerns the safeguarding of life, health, property, economic interests, the public welfare or the environment, or the managing of any such act.

Rings a bell? At least for me it did. This seems to sum up what I have been doing for the past few years in my tenure as a software engineer. In a sense, what’s missing is the regulatory bodies, the policies, licenses, code of ethics, and the rest of the bells and whistles.

Let me summarize (thank you, if you are still reading) and propose an approach towards building better software, gaining the respect of traditional ‘mature’ branches of engineering, and proving ourselves worthy of the title ‘software engineer’.

  • First, I lied about software development not having a code of ethics: Software engineering does have a code of ethics known as the IEEE CS/ACM Code of Ethics and Professional Practice, but no regulatory body to enforce it. It would be a great start to read this, and attempt to see how applicable it is in our everyday work. We may not have regulatory bodies, policies or practice licences etc. but that is not an excuse for not committing to the best standards and practices, and/or not being ethical. In the popular book Content Inc, one of the main (controversial) ideas conveyed by the author is that you should build an audience before you figure out what it is you want to sell them. Ours is a somewhat similar situation, where we need to build our audience (society expecting traditional engineering recipes) and figure out what to sell them (trust and reliance in software development using tailored/non-traditional engineering processes, backed by ethics and a sense of responsibility).
  • Second, the use of sound engineering principles: The design and architecure of the software intensive systems we build, the practices and guidelines followed when coding, the project management and costing aspects, the control and quality checks, all rely on the application of sound engineering principles in the construction of software. True, there is no universal standard or guideline dictating how we go about doing this (in fact there are a great many variety of approaches and methodologies), but whatever we tradeoff or cut-down on, it would be advisable to always reflect and check whether whatever we are doing can still be comfortably called ‘applying sound engineering principles’, without any hint of doubt in our mind.
  • Third, continuous learning and certifications: The software development world is plagued with people who are too busy learning and have no time to work, or are too busy working and have no time to learn. Jokes aside, continuous learning is something we developers are familiar with, due to the evolving trends and technology waves that tow us in their wake. There is no one person or body to standardize it and tell us the how, why, what, and when to learn, but we have ample certification programs to showcase to employers how good we are. Maybe we should have that same pride and attitude, in showing that we are capable of building great software, and that our certifications and achievements are a testament to our responsibility and obligations towards our stakeholders as well.

That was not a short summary, and I apologize for that. Looking back, this post is not a negative response to the original article at ‘The Atlantic’, but instead I was interested in critically analyzing and identifying the weaknesses in software engineering, which is constantly being targeted by traditional engineering disciplines. That being said, in ending, a big salute to all the software engineers, developers, and programmers, who constantly and daily contribute in advancing and moving the field of software engineering, towards being a mature and well respected discipline and industry.
