An interesting piece in the Whats Agile and What Isn’t space.
“The construction of software is an essentially social activity typically performed by anti-social people.”
I don’t know who said that first. I doubt it was me, but I’ll take credit for it if no one else will. Or maybe I’ll take the blame. After all, the construction that we who code are anti-social by nature is a convenient construct, just as the neck-beard and the particularly pernicious “you don’t look like a software engineer” have served to pigeonhole — and thus devalue — those who practice our craft.
Stereotypes are rarely cut from whole cloth though. Those who create stereotypes are just not that good at what they do. Consider the normal view you get of coders coding: A line of people staring at one or more screens (often artfully placed), locked-in, headphones (actual or virtual) strapped on, spouting a notable series of oaths out into the cosmos at irregular intervals, punctuated by brief smiles of self-satisfaction. Yes, we do that. Yes, we do that more than a little.
But there’s so much more going on. First of all, little software these days is the product of a single mind. Problems tend to be broad, requiring input from a series of people grounded in different disciplines. Solutions tend to be no less broad, requiring the use of multiple tools from multiple cognitive toolsets. But the mind that can focus equally well on data collection and frontend design, distributed processing concerns and architecture at multiple levels is both exceedingly rare and, seemingly, if you listen to most management rhetoric, in constant danger of either winning massive lottery prizes or being crushed by rogue, on-road, public transportation.
So we build teams — or we try to. We try to build stable, self-regulating teams with a wide array of complementary talents that can build useful software within a palatable time frame. And I say “try to” because it’s damn hard to do. It’s difficult enough to find a minimal group that can cover all the conceptual needs, making sure the human dimensions are covered as well makes the process an order of magnitude more difficult.
But what does a team look like? Well, there’s the “two pizza” rule. No more active members than can be fed with two pizzas. That sets a limit of eight or so. It’s a pretty good limit; any more than that and you start needing internal management (just on a human level) and standups and such quickly become interminable. You also need able representatives of the various stakeholder groups within an organization, where ‘able’ refers to being empowered to make all but the most major calls, otherwise the call chains get unacceptably long.
It’s a non-trivial exercise to be sure.
But, actually, it’s worse than that. Not only do you need to make sure all needs are accounted for under optimal circumstances, you also need to make sure that you at least get close under suboptimal circumstances — which is, frankly, just about always. People get sick. Take vacations. Are unavailable due to some special project. Or a conference. In fact, as soon as you get to the point of having enough people to make a team truly viable, you reach the point where it is more likely than not that some member won’t be available at any given time.
So, OK. It’s impossible.
But just because it’s impossible, doesn’t mean it’s not worth trying. It’s actually essential. If Conway’s Law holds at all, that is.
And when you have a team, or part of a team, or even the germ of a team, by all means nurture it.
We’re developers. We love code.
We’re developers. We hate code. “No code is better than no code”.
We have developers. They are a great resource.
We have developers. They are a terrible expense.
Each developer is unique.
Developers are a commodity.
A long time ago, when I was a “programmer/analyst” for a major advertising firm, we ran into a bit of a conflict with someone from account management. I don’t remember the details, but it had something to do with scope changes and ill-defined requirements. And no matter how off the wall their requests were, how self-contradictory, how internally inconsistent, we had to go with them. It was disturbing and would sometimes get a little heated.
Finally a senior executive — silver-haired and well-suited as you might reasonably imagine in those immediately post-Mad Men days — took me aside, saying, “One thing you have to remember: They are a profit center. You are a cost center. The sooner you incorporate that into your being, the less discomfort you’ll feel.”
Whether you call us programmers or software engineers or developers, we’re a pretty fortunate bunch. With the exception of just a couple of downturns over the last number of decades, we’ve been generally in demand. We’ve been generally pretty well-compensated. And, perhaps because of that last item, there’s always been an attempt to commoditize us. Whether it’s the not-so-virtuous cycle of technology adoption (“we’ll use X because there are a lot of software engineers that know X so a lot of people learn X because it’s popular and some of them shouldn’t be writing code at all so the quality of those who write X goes down so…”) or off-shoring or whatever there’s a desire to make things at least predictable but mostly, well, cheaper.
And that’s a shame. Admittedly looking from the inside, developers can often have a rather broad view of a company and deep concerns for its success. And we tend to be a reasonably clever bunch as well. We do, in general, blanch at the way much of business is done, with its reliance on hierarchy and on deeply abstracted metrics (often preferring, it seems, the state of the chosen metrics over the reality of the situation) but tend not to limit our view of things to the associated bits-and-bytes we push around.
This is not to say, for a moment, that we don’t enjoy the pure delight of techie nerd-wrestling; finding a more efficient way to move data or a more effective algorithm to find a small bit of truth is always a delight. But we care about the bottom line. We have a true understanding that if the organization does not have success neither do we.
But finding the sweet spot is a non-trivial exercise. Engineers need to be engaged and involved as well as being left alone to do their jobs. They need to be appreciated as humans contributing as well as being appreciated as a resource. And they need to be respected as people who are often dealing with the unknown. Developers spend a good deal of their time finding needles in haystacks, discovering ways to model a not-completely-consistently-defined reality.
Given what we cost, finding that sweet spot is well worth it.
Just saw this post. It had to be shared. <– (that’s a link right over there. Click it! Click it!)
Read it. Really. Read it!
I am not talking about having two coders, each of which is trying to destroy the other’s life and career, being chained together and forced to pair. What I am talking about, though, is an idea to add to the list of pairing/mobbing options that exist.
One of the typical rules observed in any multi-programmer paradigm is that there is one and only one driver. That one person at the one keyboard is the only one who presses the buttons and makes the magic appear on the screen. What if we did something different than the one-driver rule?
I’m proposing doing just that. But instead of just having two different people at two different keyboards clicking away madly, we merge in ideas from TDD. In this case, one of the keyboards is writing tests, the other is writing code. Tests are an expression of requirements; code fulfills those requirements. As functionality develops, tests can be written to expose possible corners where behavior may not be as desired. Tests try to break, code is refined to fix. The adversarial back-and-forth creates a rhythm that should have an optimizing effect upon the process.
This could also be fruitfully extended to a mob programming context (and may, in fact, work better there). There would still be two drivers, but the other members of the team would be making contributions as appropriate.
[I’m looking forward to an opportunity to implement this, at least in the small. I’l report back.]
I have a copy of “The C Programming Language” (not the ANSI C EDITION).
Procedural? Check. OO? Check. Homoiconic? Check. Immutable? Check. Functional? Check, check.
I like this stuff and I sometimes write about it.
The previous entries here are items originally written for Sparefoot’s Engineering Blog, which I use here with permission. Thank y’all for that.
Create value or create language by which your colleagues can create value. It’s all value.
“People > Process” means just that. It’s unambiguous.
Narrow contexts compose a hell of a lot better.
Saying “we’ll simplify later” is the worst kind of technical debt.
Complication eats effort. And yields nothing.
Dealing with complication is like paying protection money; all it does is cost.
TEAM is a powerful concept. Multiple sets of eyes is a benefit, not a cost.
