I started working at the age of 14. I was bagging groceries and stocking shelves at the neighborhood grocer. The place was kinda gross. Weird things happened. The butcher stole steaks. The stock boys smoked cigarettes behind the building. People slept in the doorway overnight. Daily, I'd have to wander the neighborhood searching for shopping carts, folks had used to transport their groceries home. But we all knew who the boss was. Ken. Ken was a bulky man with a larger mustache. He was in charge. It was a messy franchise, but it was his messy franchise, and he let you know it. Paid only $4.15 per hour, I worked my heart out for him.
As an adult, I've encountered many organizations including tightly coordinated military units, massive enterprise software providers, high tech cost centers, and horizontal startups. The last one, the horizontal start up, is tough.
For a long time, I figured horizontal was everything. I tried to practice it too. But I learned through trial and error that many this approach is the result of uncertain leaders. Individuals who never had to lead diffuse their power through others. Sometimes it works, sometimes it doesn't.
When it does work, it is because you have the best talent on hand. Those individuals know how to mobilize, coordinate, and get things done. It works well.
When it doesn't work, it is because the talent isn't there. People work in shadows. People talk too much or not at all. Projects never have a clean end, but sprawl and never get truly finished.
Either way, a company must have the ability to draw a line, to a diagram, end to end how the widgets get fabricated. Maybe Ken designs it. Maybe the team stumbles until they figure it out. Either way, the company is only getting started when there is visible, universal alignment on the widget making.
If the process is only in your head, trust me, it is only in your head. Get drawing.
