Some years back I worked for a network equipment company. It was probably one of the worst jobs I've ever had, complete with rows of beige cubicles highlighted with sickly green trim. Not only was I told to write my Java classes mostly in caps, with few files and minimal whitespace, but each day we had hours of conference calls with a team in New Jersey. Our computers were vintage and our shell connection was slow. The "vision" was to try and catch up with whatever Cisco was doing.
Internally, the project was considered a success, but to me it was clearly a failure. I'd be shocked if the company kept a single customer from leaving, and I'm virtually positive it didn't land new ones. The website was horribly confusing and unattractive. It was intended to be a B2B site. The dilapidated culture of the company and its hollow objective coupled with a bizarre need for control yielded predictable outcomes.
Consider how Anonymous works. It started with a general vision of anarchistic attacks against centers of power. Over time, this has become specific to punishing "bad behavior" and grabbing attention. There is no five-year plan (that we know of). Something happens, folks come together -- in an IRC chat or other medium -- and collaborate on their work. Despite the lack of an overall plan, tactical successes occur.
On the other hand, lack of a plan causes Anonymous to be a slave to the news cycle. While I'm not saying its activities at the height of the Arab Spring didn't contribute, key strategic objectives were not accomplished -- for instance, the repeated calls by freedom fighters to bring down Gadhafi's satellite TV channel. This is where a plan would be helpful. I've seen a lot of organizations function with neither shared vision or a plan. I've yet to see a successful software project without both.
Control has its limits
Many managers believe that if they aren't getting the results they want, they can just put pressure on the team. But as a developer who's transitioned to a management role, I can tell you that the more I push that button, the less effective it is.
Consider the misadventures of our hacker anti-heroes. Where Anonymous has had a central nerve, it has been attacked, which has led to arrests. The effects have trickled down and negatively affected the group.
