Square Pegs, Round Holes, and Silver Bullets


People like easy answers.

Why spend time analyzing and evaluating when you can just take some thing or some technique that someone else has already put to use and be done with it?

Why indeed?

I mean, “me too” is a valid strategy, right?

And we don’t want people to get off message, right?

And we can always find a low cost, minimal disruption way of dealing with issues, right?

I mean, after all, we’ve got data and algorithms, and stuff:

The thing is, actions need to make sense in context. Striking a match is probably a good idea in the dark, but it’s probably less so in daylight. In the presence of gasoline fumes, it’s a bad idea regardless of ambient light.

A recent post on Medium, “Design Sprints Are Snake Oil” is a good example. Erika Hall’s title was a bit click-baitish, but as she responded to one commenter:

The point is that the original snake oil was legitimate and effective. It ended up with a bad reputation from copycats who over-promised results under the same name while missing the essential ingredients.

Sprints are legitimate and effective. And now there is a lot of follow-up hype treating them as a panacea and a replacement for other types of work.

Good things (techniques, technologies, strategies, etc.) are “good”, not because they are innately right, but because they fit the context of the situation at hand. Those that don’t fit, cease being “good” for that very reason. Form absent function is just a facade. Whether it’s business strategy, management technique, innovation efforts, or process, there is no recipe. The hard work to match the action with the context has to be done.

Imitation might be the sincerest form of flattery, but it’s a really poor substitute for strategy.

Storming on Design

My youngest son has recently fallen in love with the idea of being a storm chaser when he gets older. Tweet storms are more my speed. There was an interesting one last week from Sarah Mei regarding the contextual nature of assessing design quality:

Context is a recurring theme for me. While the oldest post with that tag is just under three years old, a search on the term finds hits going all the way back to my second post in October, 2011. Sarah’s tweets resonated with me because in my opinion, ignoring context is a fool’s game.

Both encapsulation and silos are forms of separation of concerns. What differentiates the two is the context that makes the one a good idea and the other a bad idea. Without the context, you can come up with two mutually exclusive “universal” principles.

A key component of architectural design, is navigating the fractals that make up the contexts in which a system exists. Ruth Malan has had this to say regarding the importance of designing “outside the box”:

Russell Ackoff urged that to design a system, it must be seen in the context of the larger system of which it is part. Any system functions in a larger system (various larger systems, for that matter), and the boundaries of the system — its interaction surfaces and the capabilities it offers — are design negotiations. That is, they entail making decisions with trade-off spaces, with implications and consequences for the system and its containing system of systems. We must architect across the boundaries, not just up to the boundaries. If we don’t, we naively accept some conception of the system boundary and the consequent constraints both on the system and on its containing systems (of systems) will become clear later. But by then much of the cast will have set. Relationships and expectations, dependencies and interdependencies will create inertia. Costs of change will be higher, perhaps too high.

This interrelationship can be seen from the diagram taken from the same post:

It’s important to bear in mind that contexts are multi-dimensional. All but the very simplest of systems will likely have multiple types of stakeholders, leading to multiple, potentially conflicting contexts. Accounting for these contexts while defining the problem and while designing a solution appropriate to the problem space is critical to avoiding the high costs Ruth referred to above.

Another takeaway is that context can (and likely will) change over time. Whether it’s changes in terms of staffing (as Sarah noted) or changes in the needs of users or changes in technology, a design that was fit for yesterday’s context can become unfit for today’s and a disaster for tomorrow’s.
