Vertical Integration

One of the coolest things about Tesla’s business, apart from its success and all that, is the use of vertical integration. Elon Musk does this as well with SpaceX. I think software engineers have a lot to learn from this. We have a tendency to specialize, and it leads to inefficiencies in what we do.

One area of interest here is Development Operations. A common case with DevOps is that the DevOps technicians are shared resources, and developers sort of shrug and assume someone else will set up the Web server, security, load balancers, etc., and DevOps in turn assumes that the developer has taken these same things into account as they wrote their software.

Increasingly granular models of SDLC, which have moved to digestible ‘stories’, have further moved the developer away from the infrastructure and servers. Continue reading “Vertical Integration”

Good Metaphors

When I started a job a few years ago, I was assigned to a project on a Marine Base. There was one member currently on the team as it was undergoing  staffing transition, and he had perhaps the best and most memorable welcome I have ever received, which was a great example of good metaphors in IT.

He said something along the lines of: “We have only one rule here, and it was said best by the Rock: Know your role and shut your mouth.” Continue reading “Good Metaphors”

Bad Metaphors

Several years ago, I left a dinner table of colleagues wishing a question had gone unasked. We were having dinner before a big release which included a major migration for a business unit, and a product manager said something like ‘This is like the night before the big game to you guys, right?”

I sat upright, and launched into, what was, to me, an impassioned motivational speech about comparing a multi-year software project’s final deployment to a game where the likelihood of success stood around 50%. I think it’s very important to keep in mind that modern engineering requires at least a 90% delivery probability, if not 100%. Sports is a competition whose mechanics can be good metaphor, but whose outcomes probably can’t. Continue reading “Bad Metaphors”

A Quantum of Programming

As I’ve worked through almost two decades as a software developer, I’ve often wondered about the relationship between time and features. Basically, should the ‘explainability’ of a feature be proportional to its time to develop. I think it should. This can be generalized as: A small feature should take a small time to develop.

In physics, a quantum is the smallest divisible amount of energy that a thing can have. In software, I think that a ‘Quantum of Programming’ is the smallest unit of work that is actually a piece of usable software. Continue reading “A Quantum of Programming”

Welcome. A blog has to start somewhere

Welcome to my Blog. After years of considering it, I’ve decided to put together a site that allows me to jot down my various musings and ideas about my profession. I hope that I can help someone out somewhere, and that maybe I have some original ideas to contribute.

My main interests here are not technology per se, but but to be a good manager, build good teams, and then replicate this, so that one can continue to deliver good software and engineering over the course of a career.
